Insulation in Andover, MN
Most Andover homes were built during the same 1985-2005 boom window, which means most of them share the same insulation problems: code-minimum R-30 attics that have settled over 20-plus years, open bypasses at the garage-to-living-space junction, and crawl spaces that were never properly sealed against Anoka County’s humid summers and sub-zero winters. Crawl Space Encapsulation & Vapor Barrier work is the foundation of what we do here, because the split-levels and ramblers common to Andover trap moisture differently than newer construction. If your heating bill feels too high for the square footage you’re heating, call Walt’s Insulation at (866) 751-4428 and we’ll tell you exactly what’s going on up there.
Why Andover Homes Are Different
Andover sits in IECC Climate Zone 6, where sustained cold snaps turn any gap in attic air sealing into an ice dam waiting to happen. The housing stock makes this worse, not better: most of the city’s ramblers, split-levels, and two-story colonials were built by high-volume developers who installed R-30 fiberglass batts and called it done. That was the code at the time. Two to three decades later, those batts have settled in the large open attic planes common to 1990s Andover construction, and the bypasses that were never sealed at top plates and rim joists are now the primary driver of winter heat loss. One signature failure we see across Andover’s tract homes is the garage-to-living-space attic junction: the builders rarely sealed it, and every hard winter it produces ice dams directly above the garage eave. That’s not a roof problem. It’s an air sealing problem.
Our Main Andover Services
Two jobs dominate our calls from Andover: attic insulation top-ups for homes built in the 1990s that are still sitting at R-30, and the attic air sealing those homes never got in the first place. Here’s what each one involves locally.
Attic Insulation in Andover
When we inspect an Andover attic, the story is almost always the same: original fiberglass batts, settled unevenly, with bare spots at the eaves and heat pouring through the large open planes above the garage and living room. Most of these homes were built to R-30, but Minnesota’s current standard is R-49, and two decades of settling has dropped the real-world performance well below even that. We blow new insulation over, around, and in place of what’s already there, and we seal the bypasses the original builders skipped. For the full local picture, see Attic Insulation in Andover.

Crawl Space Encapsulation & Vapor Barrier in Andover
Crawl space encapsulation in Andover is the single most impactful upgrade you can make to a 1990s split-level or rambler, because those homes were built with vented crawl spaces that were never designed for Minnesota’s humidity swings. A vented crawl breathes warm, wet air in summer, which condenses on cool floor joists, and it breathes cold air in winter, which chills the living room floor while your furnace works overtime. In Andover, where the water table runs high in spring and the sub-zero weeks arrive fast in January, sealing that space with a vapor barrier and closed-cell foam changes the comfort of the entire main level. We’ve been doing Crawl Space Encapsulation & Vapor Barrier work across Anoka County since our founding, and the failure patterns here are consistent enough that we know exactly what to look for before we quote a single number.
Crawl Space Vapor Barrier
Signs you need it
You smell must or damp air when you open the crawl access, or you see condensation on the underside of the floor joists from inside the crawl. High indoor humidity in summer is another tell, especially in Andover’s split-levels.
What it costs in Andover
A crawl space vapor barrier in Andover typically runs $3 to $7 per square foot depending on access, height, and whether the space is clean or full of old debris.
How we do it
We clean the floor, level the worst dips, and lay a heavy-duty poly barrier across the entire ground surface, sealing seams and attaching it to the foundation walls. Then we seal the vents so the crawl stops breathing outside air.
Crawl Space Encapsulation
Signs you need it
Your floors are cold in winter no matter how high the thermostat goes, or you’re seeing mold or moisture stains on the rim joist area of the crawl. Rodent activity in the crawl is another strong signal it’s time to seal the space completely.
What it costs in Andover
Full crawl space encapsulation in Andover runs $3 to $7 per square foot, with total project prices typically landing between $4,000 and $9,000 depending on square footage and whether you want foam on the walls or just a barrier and dehumidifier.
How we do it
We install vapor barrier across the floors and up the walls, foam the rim joist and any open wall cavities, and add a dehumidifier sized to the space. The result is a conditioned, dry, sealed crawl that matches the temperature of your house.
Crawl Space Moisture Control
Signs you need it
Humidity readings above 60% in the crawl, visible efflorescence on the block walls, or a musty odor that creeps into the main living space are all signs your crawl is holding water.
What it costs in Andover
Moisture control work, which includes a vapor barrier and sealing, runs $3 to $7 per square foot in Andover; adding a dehumidifier and drainage work can push the total toward $10,000 for larger or problem crawls.
How we do it
We find where the water is coming from first, then seal, drain, or redirect it before laying the barrier. Without solving the water source, no amount of plastic on the floor will last.
What Crawl Space Encapsulation & Vapor Barrier Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Vapor barrier only | $3 to $7 per sq. ft. |
| Full encapsulation | $4,000 to $9,000 |
| Moisture control + dehumidifier | $5,000 to $10,000 |
Will encapsulation fix cold floors in my Andover split-level?
Yes. Sealing the crawl space and insulating the rim joist stops cold outside air from moving under and through the floor structure. Most of our Andover customers notice warmer floors within a day or two of the job being finished. Call (866) 751-4428 for a specific assessment of your crawl.
Is a vapor barrier the same as encapsulation?
No. A vapor barrier covers the floor and sometimes the walls, but encapsulation seals the entire space, including vents, rim joist, and open cavities, and adds moisture control. For Andover homes with vented crawls, encapsulation is the more complete fix.
Spray Foam Insulation in Andover
Spray foam is the best answer to the two problems Andover’s 1990s tract homes struggle with most: bypasses the original builders never sealed, and rim joists that leak cold air into the floor system all winter. Closed-cell foam does two jobs at once: it insulates and it air-seals, which means it hits the exact failure points we find in Andover’s ramblers and split-levels, where fiberglass alone was never going to keep Zone 6 cold out. Whether you’re foaming a rim joist or a garage ceiling that shares an attic plane with the house, Spray Foam Insulation is the highest-performance option we install, using Icynene and Demilec systems we’ve trusted for years.
Closed-Cell Spray Foam
Signs you need it
You have a rim joist that’s exposed to cold air all winter, or you want the highest R-value per inch in a tight cavity. Closed-cell also works where moisture control matters, like Andover crawl spaces and rim joists.
What it costs in Andover
Closed-cell spray foam in Andover runs $2.50 to $5.50 per board foot installed, with rim joist jobs typically landing between $2,000 and $4,500 for an average rambler or split-level.
How we do it
We prep the surfaces, protect the surrounding area, and spray the foam at controlled thickness to reach the target R-value. Once cured, it’s a rigid air barrier and insulation in one continuous layer.
Rim Joist Spray Foam
Signs you need it
Cold floors around the edges of your main level in January, or you can feel a draft along the basement or crawl rim joist. Andover’s tract homes often have bare fiberglass stuffed in the rim, which doesn’t stop airflow.
What it costs in Andover
Rim joist spray foam in Andover runs $2.50 to $5.50 per board foot, with most full-perimeter rim jobs totaling $2,000 to $4,500 depending on the number of joist bays.
How we do it
We remove any failed fiberglass, clean the rim, and spray closed-cell foam into each bay to seal and insulate in one pass. It takes a crew less than a day for most Andover homes.
What Spray Foam Insulation Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Closed-cell foam (per board ft.) | $2.50 to $5.50 |
| Rim joist job (full perimeter) | $2,000 to $4,500 |
| Garage ceiling or roof deck | $3,000 to $7,000 |
Is spray foam worth the cost in Andover’s climate?
For most Andover homes, yes, especially at the rim joist and garage-to-attic junction. Foam air-seals while it insulates, which is exactly what’s missing in the 1990s tract construction that dominates the city. Call (866) 751-4428 and we’ll tell you if your house is a good candidate.
Can you spray foam an Andover attic that already has fiberglass?
It depends. We usually recommend removing settled fiberglass first if you’re foaming the attic floor, because old insulation reduces coverage and hides bypasses. We’ll give you a straight answer on whether removal is needed for your specific attic.
Blown-In Insulation in Andover
Blown-in insulation is the most practical upgrade for the classic Andover home: a 1990s two-story or rambler with R-30 fiberglass batts that have settled for two decades and no longer touch the top plates. We blow Owens Corning fiberglass or GreenFiber cellulose over the existing layer to bring the attic up to R-49, which is what Minnesota homes need now, not what the code allowed in 1995. The open attic planes on Andover’s larger tract lots make this fast and affordable, and because most of these homes share the same construction, our crews know exactly where the thin spots will be before we even start. Learn more about how Blown-In Insulation works across different ceiling types.
Blown-In Cellulose
Signs you need it
Your attic insulation is below the top of the ceiling joists, meaning you’re under-insulated for Zone 6. Cellulose packs dense enough to cut air movement through the layer, which helps in Andover’s windy winters.
What it costs in Andover
Blown-in cellulose in Andover runs $1.00 to $3.00 per square foot, with a typical 1,500-square-foot attic landing between $1,500 and $4,500 depending on depth and prep.
How we do it
We air-seal the attic floor first, then blow cellulose to a consistent depth that hits the R-value target for Minnesota. The sealing step matters as much as the insulation itself in Andover’s older tract stock.
Blown-In Top-Up
Signs you need it
Your existing insulation is in decent shape but too thin, usually settled R-30 batts with bare spots at the eaves. A top-up is the cheapest way to get to R-49 without a full removal.
What it costs in Andover
A blown-in top-up in Andover runs $1.00 to $3.00 per square foot, so a 1,200-square-foot attic top-up typically lands between $1,200 and $3,600.
How we do it
We seal the obvious bypasses, then blow new material directly over the old to bring the whole plane to a uniform R-49. The job is usually done by early afternoon.
What Blown-In Insulation Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Blown-in fiberglass or cellulose | $1.00 to $3.00 per sq. ft. |
| Attic top-up (average Andover attic) | $1,500 to $4,500 |
| Dense-pack wall insulation | $3.00 to $6.00 per sq. ft. |
Can you blow insulation over my old Andover attic batts?
Yes, that’s what a top-up is. The old batts stay in place, and we blow new material over them to reach R-49. It’s the most budget-friendly way to fix settled insulation in Andover’s 1990s homes. Call (866) 751-4428 for a per-square-foot quote.
How long does blown-in insulation last in Minnesota?
Cellulose and fiberglass both last decades, but they settle, especially over large open attic planes like those in Andover’s ramblers. Most homes that were insulated in the 1990s have lost meaningful R-value and are due for a top-up now.
Radiant Barrier Installation in Andover
Radiant barrier works differently in Andover than it does down south, because our problem is heat loss, not just heat gain, but the roof deck still absorbs summer sun and transfers it into the attic all through July. A foil radiant barrier on the underside of the roof deck reflects that heat back out before it soaks into your attic floor insulation, keeping second-story rooms noticeably cooler on the hottest days. It’s a good pairing with attic air sealing for the city’s two-story colonials, where the upper level always runs 10 degrees warmer. We install Radiant Barrier Installation as a supplement to insulation, not a replacement for it.
Attic Radiant Barrier
Signs you need it
Your second story is consistently hotter than the main floor all summer, even with the AC running. Or your attic is well-insulated on the floor but still unusably hot on sunny afternoons.
What it costs in Andover
Radiant barrier in an Andover attic runs $1.00 to $3.00 per square foot of roof area, so a typical rambler roof deck lands between $1,200 and $3,600.
How we do it
We staple the foil to the underside of the roof deck or rafters, leaving a small air gap for the reflective surface to work. The key is coverage across the entire roof plane, including over the garage.
Radiant Barrier & Ventilation
Signs you need it
Your attic is hot despite having soffit and ridge vents, or you’re noticing the upstairs thermostat working hard on days when the outside temperature isn’t extreme. Poor ventilation and no radiant barrier compound each other.
What it costs in Andover
Pairing radiant barrier with ventilation fixes in Andover runs $1.00 to $3.00 per square foot for the barrier, with vent repair or added venting priced separately based on what the attic actually needs.
How we do it
We check airflow from soffit to ridge first, because a radiant barrier in an unvented attic can create moisture problems. Then we install the barrier so it works with the ventilation rather than against it.
What Radiant Barrier Installation Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Radiant barrier (per sq. ft.) | $1.00 to $3.00 |
| Typical Andover attic roof deck | $1,200 to $3,600 |
| Barrier + ventilation correction | $1,500 to $4,000 |
Will a radiant barrier lower heating bills in Andover?
Not much. Radiant barrier is primarily a summer improvement, not a winter one. If your goal is lower heating bills, attic air sealing and topping up to R-49 are the moves that pay off in Andover’s winters. Call (866) 751-4428 and we’ll prioritize what actually moves the needle for your house.
Is radiant barrier safe for my Andover roof?
Yes, when installed correctly with the right air gap and ventilation. A foil barrier doesn’t trap moisture if airflow is intact. We inspect venting before any radiant barrier install so the roof assembly stays dry year-round.
Insulation Removal & Replacement in Andover
Some Andover attics need a fresh start, not a top-up. The trigger is usually one of three things: rodent damage from squirrels or mice that nested in the old fiberglass, water damage from an ice dam that finally broke through, or original insulation that’s so settled and compressed it’s doing more harm than good. In a city where most homes hit their 25-to-35-year mark at the same time, removal jobs are becoming more common every year, and they’re the right call when contamination or compression means old material can’t be saved. We handle the full Insulation Removal & Replacement process, from suction removal to fresh Owens Corning or GreenFiber blown back in.
Contaminated Insulation Removal
Signs you need it
You’ve had mice, squirrels, or raccoons in the attic, or there’s visible staining, droppings, or a strong odor in the insulation. Damaged material can’t be sanitized; it has to go.
What it costs in Andover
Contaminated insulation removal in Andover runs $2.00 to $5.00 per square foot, with disposal and sanitizing included; a typical 1,200-square-foot attic lands between $2,400 and $6,000.
How we do it
We vacuum out the old material with high-powered suction, disinfect the surfaces, and then blow or bat new insulation in. The sequencing matters: removal, sanitizing, air sealing, then insulation.
Attic Insulation Removal
Signs you need it
Your insulation is uneven, flat, stained, or full of rodent tunnels, or you’re preparing for spray foam on the attic floor. Old compressed batts don’t do their job, and they hide the bypasses we need to seal.
What it costs in Andover
Attic insulation removal in Andover runs $2.00 to $5.00 per square foot; a full removal and replacement on a two-story colonial typically lands between $3,000 and $7,000.
How we do it
We suction everything out down to the drywall, inspect and seal the bypasses that were buried, then install fresh insulation to the R-value your Andover home actually needs.
What Insulation Removal & Replacement Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Insulation removal (per sq. ft.) | $2.00 to $5.00 |
| Removal + replacement | $3,000 to $7,000 |
| Contaminated removal + sanitizing | $2,400 to $6,000 |
Can I just blow new insulation over rodent-damaged material?
No. The droppings and urine stay in the material, and the odor and air quality issues don’t go away just because it’s covered. Removal is the correct fix for contaminated insulation in Andover attics. Call (866) 751-4428 and we’ll assess whether yours qualifies.
How long does a removal and replacement take?
Most Andover attics are done in one to two days, including the new insulation. Larger spaces or heavy contamination may add a day. We’ll give you a firm timeline when we quote the job.
Attic Air Sealing in Andover
If your Andover home was built between 1985 and 2005, the odds are high that the attic floor was never air-sealed at the top plates, wire penetrations, or can lights, because the high-volume builders who developed this city didn’t make it part of the spec. Those small gaps add up fast in Zone 6 winter: warm air rises through them into the attic, melts the snow on your roof, and refreezes at the eaves as ice dams. Air sealing is the first thing we do before adding insulation to any Andover attic, because insulation over unsealed bypasses is like wearing a warm coat with the zipper open. For the full picture on what gets sealed and why, see our Attic Air Sealing page.
Top Plate & Penetration Sealing
Signs you need it
Ice dams over the garage eave, rooms that lose heat immediately after the furnace cycles off, or you can see dirty fiberglass around the edges of the attic floor where warm air has been filtering through.
What it costs in Andover
Top plate and penetration sealing in Andover runs $1.50 to $3.50 per square foot of attic floor, with a typical rambler landing between $1,800 and $4,200.
How we do it
We pull back insulation at every top plate and penetration, seal the gaps with foam or caulk, then set the insulation back in place and top it up as needed.
Attic Hatch Sealing
Signs you need it
The hallway near your attic hatch feels cold in winter, or you can feel a draft when standing under the hatch. A bare plywood hatch is one of the leakiest points in any Andover home.
What it costs in Andover
Attic hatch sealing in Andover is usually done as part of a broader air sealing job, and it’s included in the $1.50 to $3.50 per square foot range; a standalone hatch fix is typically under $500.
How we do it
We weatherstrip the hatch frame, insulate the hatch door itself, and add a foam board cover so the opening stops leaking conditioned air into the attic.
What Attic Air Sealing Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Air sealing (per sq. ft.) | $1.50 to $3.50 |
| Full attic seal (rambler) | $1,800 to $4,200 |
| Hatch sealing only | $200 to $500 |
Does air sealing really stop ice dams in Andover?
It’s the single most effective thing you can do. Ice dams form when warm attic air melts snow from underneath, and air sealing stops the warm air at its source. Pair it with R-49 insulation and Andover’s signature garage-eave dams become rare. Call (866) 751-4428 to schedule an attic inspection.
Can I seal the attic myself with cans of foam?
We don’t recommend it. The gaps that matter in Andover’s tract homes are under the insulation at top plates, and they’re hard to reach safely. It takes a pro to pull insulation back, seal systematically, and replace it without leaving new gaps.
Wall Insulation in Andover
The exterior walls in Andover’s 1990s tract homes usually have fiberglass batts behind the drywall, but they were rarely installed carefully, and the builders almost never sealed the framing around them. That means cold air moves through outlets, baseboards, and around windows, and the wall cavities don’t perform anywhere near their rated R-value. We fix this with drill-and-fill and injection foam, which fills every cavity dense without tearing out drywall, and it’s one of the most underrated comfort upgrades for Andover’s split-levels and two-stories. See how Wall Insulation compares across methods before you decide.
Injection Foam Wall Insulation
Signs you need it
Rooms along exterior walls are consistently colder than the center of the house, or you feel drafts at outlets and baseboards on winter nights. Your walls probably have gaps in the original batt installation.
What it costs in Andover
Injection foam wall insulation in Andover runs $3.00 to $6.00 per square foot of wall area, with a typical split-level exterior wall job landing between $3,500 and $7,500.
How we do it
We drill small holes through the drywall or siding, inject foam that expands to fill every cavity and seal gaps, then patch the holes cleanly. The wall behaves like it was built with foam from day one.
Interior Wall Soundproofing
Signs you need it
You hear every conversation and TV in the next room, or the home office shares a wall with a busy hallway. Andover’s open-plan colossals and split-levels often have hollow interior walls that carry sound.
What it costs in Andover
Interior wall soundproofing in Andover runs $3.00 to $6.00 per square foot, with a single bedroom wall typically landing between $600 and $1,500.
How we do it
We inject dense-pack cellulose or foam into the cavities through small holes, which adds mass and blocks sound transmission. The difference is immediate and doesn’t require new drywall.
What Wall Insulation Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Injection foam or drill-and-fill | $3.00 to $6.00 per sq. ft. |
| Exterior wall job (split-level) | $3,500 to $7,500 |
| Interior wall soundproofing | $600 to $1,500 per wall |
Can you insulate walls without tearing out drywall?
Yes, that’s exactly what drill-and-fill and injection foam are for. We work through small holes we patch afterward, so your Andover home’s walls stay intact while the insulation goes in. Call (866) 751-4428 and we’ll walk you through the method that fits your house.
Will wall insulation lower my heating bill in Andover?
It helps, especially if your walls were never sealed properly, but attic air sealing and R-49 insulation usually deliver bigger savings first. We’ll tell you honestly where the most cost-effective fix is for your specific home.
Attic Cleaning & Rodent Proofing in Andover
Andover’s larger wooded lots and mature oak trees are beautiful, but they’re also a highway for squirrels, mice, and raccoons to get onto roofs and into attics, and the city’s 1990s tract homes have predictable entry points: gable vents, soffit gaps, and the garage-to-attic junction we keep coming back to. Once rodents are in, they nest in the fiberglass, chew wiring, and leave the insulation saturated with waste. We clean the whole space out, sanitize it, and then seal every entry point so they can’t come back. That last part is what separates a real fix from a trap-and-release cycle. Full details on our Attic Cleaning & Rodent Proofing process are on the hub page.
Attic Cleanout
Signs you need it
You hear scratching in the attic at dawn or dusk, see droppings in the insulation, or the attic smells stale and animal-like. All of it means something was living up there and left a mess behind.
What it costs in Andover
Attic cleanout in Andover runs $2.00 to $5.00 per square foot, with a typical 1,500-square-foot attic landing between $3,000 and $7,500 when sanitizing is included.
How we do it
We remove the contaminated insulation and debris, vacuum the surfaces, and sanitize the space before installing new insulation. It’s a full reset for the attic environment.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents removed before and they came back, or you can see daylight through gaps at the roofline, gable vents, or soffit. Exclusion is the only permanent fix.
What it costs in Andover
Rodent proofing and exclusion in Andover runs $500 to $3,500 depending on how many entry points exist and how accessible they are; combined with cleanout, most jobs land between $3,500 and $10,000.
How we do it
We identify every entry point, seal them with steel mesh, foam, or flashing, and inspect the roof-to-wall junctions that Andover’s builders left open. No entry points means no re-entry.
What Attic Cleaning & Rodent Proofing Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Attic cleanout + sanitizing | $3,000 to $7,500 |
| Rodent proofing & exclusion | $500 to $3,500 |
| Cleanout + exclusion + new insulation | $3,500 to $10,000 |
Will rodents come back after cleanout and proofing?
Not through the same entry points, because we seal them with materials that resist chewing and weather. The key is sealing every gap, including the garage-to-attic junction that defines Andover’s tract construction. Call (866) 751-4428 and we’ll do a full entry-point audit.
Do I need to replace insulation after rodents?
In most cases, yes. Rodent urine and droppings can’t be cleaned out of fiberglass, and the material loses its thermal performance once it’s compressed and tunneled. We’ll tell you if yours can be salvaged or if removal is the right call.

Home Energy Audit in Andover
An energy audit in Andover is the shortest path from “my bills feel high” to knowing exactly where your heated air is leaving the house, and it’s especially useful for the city’s 1990s tract homes, which tend to leak in predictable, builder-specific ways. We run a blower door test that depressurizes the house and lets us feel every gap, and we pair it with thermal imaging so you can see the cold spots in real time. From there, the priority order is clear: air sealing, attic insulation, rim joist, and then walls if needed. That’s how Home Energy Audit work turns guesswork into a list. Our audit is a diagnostic, not a sales pitch, and we’ll show you the data before recommending anything.
Blower Door Test
Signs you need it
Your heating bills are higher than neighbors with similar houses, rooms are unevenly heated, or you’ve been told you need insulation and want proof before spending money.
What it costs in Andover
A blower door test in Andover runs $200 to $600, and it’s often bundled with a full home energy audit that includes thermal imaging and insulation inspection.
How we do it
We seal a high-powered fan into an exterior doorway and depressurize the house, which pulls outdoor air through every leak. We measure the total leakage and locate the biggest gaps.
Thermal Imaging Inspection
Signs you need it
Certain rooms are always cold, you suspect missing insulation in a wall or attic corner, or you want visual evidence of where heat escapes before committing to work.
What it costs in Andover
Thermal imaging as part of a home energy audit in Andover runs $200 to $600 for the full audit; standalone thermal scans are typically included when we’re already on site for another job.
How we do it
We run an infrared camera across walls, ceilings, and floors while the house is under blower door pressure, which makes even small cold spots show up clearly on the image.
What Home Energy Audit Costs in Andover
| Item | Typical range in Andover |
|---|---|
| Blower door test only | $200 to $600 |
| Full energy audit + thermal imaging |

In Andover, price depends heavily on attic access and how a home’s junctions were built: garage-to-living-space attic connections often need extra sealing work, and removing old, ice-dam-damaged material before adding new insulation adds to the total. We write the final number in writing before any crew starts.
FAQs About Insulation in Andover, MN
How quickly can we schedule insulation work in Andover?
Most Andover jobs get scheduled within a week or two of the estimate. Because ice dams and heat loss show up fastest in the coldest weeks of winter, we try to prioritize air sealing and attic requests as soon as temperatures drop.
Do we need a permit for insulation work in Andover?
Routine attic and wall insulation typically doesn’t require a separate permit. Many Andover homes were built with R-30 attic batts that have since settled well below that level, so we check current conditions in your attic before quoting rather than assuming the original build still performs as designed.
How does the written estimate work?
We inspect the attic, rim joists, and any problem areas like the garage-to-living-space junction in person. From there we write up a price broken out by task, so you know the full cost for your Andover home before any work begins.
Which areas do you serve besides Andover?
We also work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If you’re in one of those areas, or just outside Andover, reach out and we’ll confirm scheduling.
What happens to the old insulation removed from an Andover attic?
We bag it and haul it away as part of the job, whether it’s settled fiberglass batts or material damaged by ice dam leaks. If we find water damage from past ice dams, we’ll flag it before closing the attic back up.

What Andover Customers Say
"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."
- Helen Tran"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
- Nadia Haddad"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
