Insulation in Houston, TX
Crawl space encapsulation and vapor barrier work in Houston is the single most important defensive upgrade you can make on a pier-and-beam house, and we approach it differently than a northern contractor would. Houston’s Climate Zone 2A humidity means your crawl space is actively pulling moisture into your floor joists for six-plus months every year, and the 1920s-1950s bungalows in the Heights, Montrose, and Garden Oaks almost never had a proper vapor strategy installed. If your floors feel damp, your house smells musty, or your AC struggles to hold temperature, call Walt’s Insulation at (866) 751-4428 and we’ll assess what’s actually happening under your home.
Why Houston Homes Are Different
Houston’s building stock grew fast and mostly before anyone thought hard about insulation. The slab-on-grade ranch homes built from the 1960s through the 1990s in Meyerland, Clear Lake, and the Energy Corridor went up before Texas adopted the IECC, which means many have thin attic insulation and ducts running through unconditioned attics that hit 150°F or more all summer. When your ductwork bakes above your ceiling while your living room is set to 74°F, your AC is fighting a losing battle, and attic insulation alone won’t fix the duct problem.
The real Houston wildcard is vapor drive. In Climate Zone 2A, moisture moves inward during summer: hot, wet outdoor air pushes toward your cool, conditioned interior. That’s the opposite of what a Minneapolis contractor expects, and it’s why we never default to interior-side vapor retarders on wall work here. A vapor barrier placed on the wrong side in Houston doesn’t just fail, it actively feeds mold inside wall cavities. Uri in February 2021 exposed the other side of the problem: under-insulated attics and uninsulated pipe runs made Houston homes far colder than they should be during freezes, and that remediation demand is still part of our regular conversation with homeowners.
And in southwest Houston specifically, we see a failure mode most cities don’t have. Homes in Meyerland and similar 1960s-1970s subdivisions that flooded during Harvey-era storms often had wet fiberglass batts stuffed back into attic floors by restoration crews rather than properly replaced. That insulation is now compressed, contaminated, or thermally useless. A local technician learns to check for post-flood insulation damage on every single job in those neighborhoods.
Our Main Houston Services
Most Houston homeowners call us first about their attics: either the heat radiating down from an under-insulated attic floor, or the compounded problem of ducts baking in 150°F air. Here are the two services that dominate our Houston call volume.
Attic Insulation in Houston
Attic insulation is the highest-return upgrade for most Houston houses, but the way we install it here matters. A standard attic-floor fiberglass job does almost nothing for the ductwork baking above it, which is why we evaluate the whole attic, including air leaks and radiant heat, before recommending a material. For slab-on-grade ranches in Meyerland or Clear Lake with original 1990s insulation, a Attic Insulation in Houston audit usually starts with measuring what’s already up there and checking whether post-flood or post-rodent damage means it should come out first.

Crawl Space Encapsulation & Vapor Barrier in Houston
Crawl space encapsulation in Houston is less about comfort and more about stopping structural decay and indoor air contamination. Pier-and-beam homes in the Heights, Montrose, and Garden Oaks sit over open dirt or decades-old vented crawl spaces, and Houston’s summer dew points above 70°F mean that dirt stays wet for months. That moisture wicks into floor joists, supports mold, and gets pulled straight into your living space by the stack effect. A Crawl Space Encapsulation & Vapor Barrier job seals the floor and walls, isolates the space from the ground, and controls the humidity at the source instead of treating the symptoms.
Crawl Space Vapor Barrier
Signs you need it
You smell dampness or mildew coming up through the floors, hardwood is cupping, or you see condensation on ductwork and pipes under the house.
What it costs in Houston
A crawl space vapor barrier install in Houston typically runs $1,200-$4,000 depending on square footage, access height, and whether the crawl space is vented or sealed.
How we do it
We clear debris, level the floor where needed, then lay a heavy reinforced polyethylene liner across the ground and up the foundation walls, mechanically fastening it at the perimeter and sealing all seams and penetrations.
Crawl Space Encapsulation
Signs you need it
Your floors feel humid even when the AC is running, you’ve had recurring mold in the crawl space, or your energy bills stay high through every Houston summer.
What it costs in Houston
Full crawl space encapsulation in Houston normally lands between $4,000 and $10,000 when it includes a sealed vapor liner, wall insulation, and a dehumidifier sized for the space.
How we do it
We seal vents, install the full vapor barrier, insulate the perimeter walls, and add a properly sized dehumidifier so the space stays dry without venting to Houston’s humid outdoor air.
What Crawl Space Encapsulation & Vapor Barrier Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Crawl space vapor barrier (basic liner) | $1,200-$4,000 |
| Full encapsulation with dehumidifier | $4,000-$10,000 |
| Perimeter spray foam insulation (2-inch closed-cell) | $2,500-$5,500 |
| Crawl space cleanout and sanitizing | $800-$2,500 |
Is a vapor barrier enough, or do I need full encapsulation in Houston?
A vapor barrier alone controls ground moisture, which is often enough for vented crawl spaces with good airflow. In Houston’s high-humidity summers, however, most pier-and-beam homes need encapsulation with a dehumidifier to keep humidity below 55% and stop condensation on ducts. Call (866) 751-4428 for a specific recommendation.
Why does my Houston crawl space smell worse in summer?
Houston’s summer air holds a lot of moisture, and when it enters a cool vented crawl space, the relative humidity spikes and water condenses on joists and ductwork. That standing moisture feeds mold and creates the musty smell. Sealing and dehumidifying fixed this for most homes we work on. Call (866) 751-4428 to schedule a look.
Spray Foam Insulation in Houston
Spray foam attic encapsulation delivers bigger energy savings in Houston than almost anywhere else in the Sun Belt because of one local fact: our ducts run through unconditioned attics that hit 150°F+ every summer. Sealing the roof deck with Spray Foam Insulation brings the attic and the ductwork into conditioned space, so the air leaving your AC isn’t being reheated before it reaches your bedroom. It’s the defining high-value upgrade in this market, especially on 1960s-1990s slab ranches in Meyerland, Clear Lake, and the Energy Corridor where duct runs are long and fully exposed.
Open-Cell Spray Foam
Signs you need it
Rooms farthest from the AC never cool down, upstairs bedrooms are 8-10°F warmer than downstairs, or your electric bill spikes every July and August.
What it costs in Houston
Open-cell spray foam in a Houston attic roof deck typically runs $2.50-$4.00 per board foot installed, which puts most 1,500-square-foot attics in the $7,500-$12,000 range.
How we do it
We remove or redirect existing insulation at the roofline, seal bypasses, then spray open-cell foam across the underside of the roof deck to create an air-sealed, conditioned attic.
Closed-Cell Spray Foam
Signs you need it
You want maximum R-value per inch, you’re insulating a flood-prone or humid area, or you need structural racking strength on an older frame.
What it costs in Houston
Closed-cell spray foam in Houston runs $4.50-$7.00 per board foot, which puts a 2-inch roof-deck application on a 1,500-square-foot attic around $13,500-$21,000.
How we do it
We spray closed-cell foam in lifts to the specified depth, typically 2-3 inches on a Houston roof deck, where it acts as both insulation and a vapor retarder in one continuous layer.
What Spray Foam Insulation Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Open-cell roof deck (1,500 sq ft) | $7,500-$12,000 |
| Closed-cell roof deck (1,500 sq ft, 2 inches) | $13,500-$21,000 |
| Rim joist spray foam (closed-cell) | $1,500-$3,500 |
| Garage ceiling spray foam | $2,000-$4,500 |
Does spray foam in my Houston attic actually lower my electric bill?
Yes, and it’s one of the few upgrades where Houston sees outsized returns. Moving ductwork out of a 150°F attic and into conditioned space can cut cooling load noticeably, often 15-25% on a hot humid day. Call (866) 751-4428 for a realistic estimate on your house.
Open-cell or closed-cell for a Houston roof deck?
Open-cell is usually the right value for a vented attic that’s being sealed, since it air-seals and insulates well at lower cost. Closed-cell makes sense when you need a vapor retarder, extra racking strength, or flood resilience. We’ll recommend one based on your roof condition. Call (866) 751-4428.
Blown-In Insulation in Houston
Blown-in insulation is the workhorse retrofit for Houston’s slab-on-grade ranches, where attic access is tight and the existing fiberglass has compressed to nothing over 30 or 40 years. It’s also the biggest cautionary story in flood-rebuilt Meyerland: restoration crews frequently stuffed wet batts back into attic floors after Harvey, and that material now insulates almost nothing. A Blown-In Insulation top-up or full replacement restores the attic’s thermal layer in a single day, and in Houston we always pair it with an air-sealing pass first, because loose-fill without sealing just filters warm air up through the gaps.
Blown-In Cellulose
Signs you need it
Your attic insulation measures under R-30, it’s uneven or trampled, or you can feel heat radiating down from the ceiling on summer afternoons.
What it costs in Houston
Blown-in cellulose in a Houston attic most often lands between $1,200 and $2,800 depending on depth, square footage, and whether we’re topping up or starting fresh.
How we do it
We air-seal the attic floor, set depth markers, then blow loose-fill cellulose evenly across the entire attic to the R-value we agreed on, typically R-38 to R-49 in Houston.
Blown-In Top-Up
Signs you need it
Your attic has some insulation but it’s settled below the tops of the joists, or one room is consistently hotter than the rest of the house.
What it costs in Houston
A blown-in top-up over existing insulation in Houston usually runs $600-$1,400, less than half the cost of a full removal-and-replacement job.
How we do it
We check the existing insulation for moisture or contamination first; if it’s dry and sound, we blow new loose-fill directly over it to reach the target depth, then re-set depth markers.
What Blown-In Insulation Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Blown-in cellulose (full attic, R-38) | $1,200-$2,800 |
| Blown-in fiberglass (full attic, R-38) | $1,500-$3,500 |
| Blown-in top-up over existing | $600-$1,400 |
| Dense-pack wall insulation (per wall section) | $2,500-$6,000 |
Should I blow new insulation over old insulation in Houston?
Sometimes. If the old material is dry, uncontaminated, and not compressed by flood or rodent activity, topping up is the most cost-effective move. If it’s wet or dirty, it should come out first, because new insulation over moldy material just hides the problem. Call (866) 751-4428 for a free inspection.
How deep should attic insulation be in Houston?
Most Houston homes benefit from R-38 to R-49 at the attic floor, which is roughly 12-18 inches of blown-in fiberglass or cellulose depending on the product. Many 1960s-1990s homes here have R-19 or less. Call (866) 751-4428 and we’ll measure yours.
Radiant Barrier Installation in Houston
Radiant barrier is one of the few insulation upgrades that pays for itself faster in Houston than almost anywhere else, because our roofs bake under direct sun from May through September. A reflective foil stapled to the underside of the roof deck bounces radiant heat back out before it can re-radiate down into your attic and onto your ceiling. On a Houston slab ranch with a dark shingle roof and an attic that hits 140°F+, a Radiant Barrier Installation can drop attic temperature by 20-30°F, which directly reduces heat gain into the ductwork and the rooms below.
Attic Radiant Barrier
Signs you need it
Your attic feels like an oven when you open the hatch, your AC runs nonstop in August, or your upstairs ceiling is warm to the touch even after sunset.
What it costs in Houston
An attic radiant barrier install in Houston typically runs $1,500-$3,500 depending on roof geometry, attic size, and whether the existing insulation needs to be worked around.
How we do it
We staple perforated reflective foil to the underside of the roof rafters, leaving the ridge and soffit vents clear so the attic still breathes while the foil blocks radiant heat.
Radiant Barrier Roof Deck
Signs you need it
You’re reroofing or building new in Houston and want the barrier integrated into the roof assembly from day one.
What it costs in Houston
Radiant barrier roof deck sheathing adds $1,500-$3,500 over standard sheathing on a typical Houston home and is best done during a reroof.
How we do it
We coordinate with your roofing contractor to install foil-faced sheathing, with the reflective side facing the attic space, before the roofing underlayment goes on.
What Radiant Barrier Installation Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Attic radiant barrier (staple-up foil) | $1,500-$3,500 |
| Radiant barrier roof deck sheathing | $1,500-$3,500 additional |
| Radiant barrier with ventilation improvements | $2,500-$5,500 |
| Garage radiant barrier | $800-$2,000 |
Does radiant barrier work in Houston’s humidity?
Yes. Radiant barrier works by reflecting heat, not by managing moisture, so Houston’s humidity doesn’t reduce its effectiveness. The key is proper ventilation, which we check on every install. Call (866) 751-4428 to see if your attic is a good candidate.
Do I need radiant barrier if I already have blown-in insulation?
Insulation slows conductive heat; radiant barrier blocks radiant heat. They work together. In Houston, the combination can reduce ceiling heat gain by 20-30% beyond insulation alone. Call (866) 751-4428 for a realistic assessment.
Insulation Removal & Replacement in Houston
Insulation removal is the step many Houston homeowners skip, and it’s the one that matters most after a flood, a rodent infestation, or 40 years of attic dust and heat. The Harvey-era rebuilds in Meyerland taught us what to look for: compressed, water-stained fiberglass that looks like insulation but insulates almost nothing. A Insulation Removal & Replacement job gets contaminated material out, sanitizes the attic floor, and lays down a clean thermal layer that actually performs in Houston’s heat.
Attic Insulation Removal
Signs you need it
Your attic insulation is compacted, water-stained, rodent-soiled, or so old it’s broken down into dust and matted clumps.
What it costs in Houston
Attic insulation removal in Houston usually runs $1,500-$3,000 including bagging, vacuuming, and disposal for a typical 1,200-2,000-square-foot attic.
How we do it
We use a commercial insulation vacuum to pull the old material out through a contained hose system, bag it, and clean the attic deck down to the drywall or decking.
Insulation Replacement
Signs you need it
You’ve had a roof leak, a rodent problem, or a flood event, and the insulation is stained, compressed, or full of droppings.
What it costs in Houston
Replacing attic insulation in Houston typically runs $2,000-$5,500 when it includes removal, air sealing, and new blown-in or batt insulation at R-38.
How we do it
We remove the old material, air-seal the attic floor, then install fresh insulation to the target R-value, with a clean bill on depth and coverage.
What Insulation Removal & Replacement Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Attic insulation removal (1,200-2,000 sq ft) | $1,500-$3,000 |
| Contaminated insulation removal and sanitizing | $2,000-$4,500 |
| Full removal, air sealing, and replacement (R-38) | $2,000-$5,500 |
| Vermiculite removal and containment | $4,000-$9,000 |
Do I need to remove old insulation before adding new in Houston?
Not always, but if the old material is wet, moldy, rodent-damaged, or compressed from flood recovery, yes. Adding new insulation over contaminated material traps the problem and reduces the new insulation’s effectiveness. We inspect before recommending. Call (866) 751-4428.
How do I know if my Houston attic insulation is water-damaged?
Water-damaged insulation looks compressed and matted, often with dark staining or a musty smell. In flood-rebuilt Meyerland homes, we frequently find batts that were refluffed but never dried, and they hold heat almost zero. Call (866) 751-4428 for an inspection.
Attic Air Sealing in Houston
Air sealing is the unglamorous step that makes every other attic upgrade work in Houston. Your attic floor is full of penetrations: top plates, wire holes, can lights, duct boots, and a leaky hatch. In a Houston summer, those gaps let conditioned air escape into a 150°F attic while pulling humid outdoor air into the house. A Attic Air Sealing pass closes those leaks with foam and caulk, and it’s the first thing we do before blowing in new insulation because insulation alone doesn’t stop air movement.
Attic Floor Air Sealing
Signs you need it
Rooms are dusty, you can feel warm air near interior walls, or your AC runs constantly but the house never feels tight.
What it costs in Houston
Full attic floor air sealing in Houston typically runs $1,000-$2,500 depending on attic size, access, and how many penetrations need foam.
How we do it
We map the attic floor, seal top plates, wire and plumbing penetrations, and any chase openings with spray foam or caulk, then check the hatch and duct boots.
Top Plate & Penetration Sealing
Signs you need it
You can see daylight or feel air movement around interior wall tops from inside the attic, or you’ve noticed dust trails in the insulation.
What it costs in Houston
Top plate and penetration sealing in Houston runs $500-$1,500, and it’s the most cost-effective leak-reduction work we do in this market.
How we do it
We foam or caulk every gap along the top plates, around vent stacks, electrical penetrations, and any other holes that pass from the conditioned space into the attic.
What Attic Air Sealing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Full attic floor air sealing | $1,000-$2,500 |
| Top plate and penetration sealing | $500-$1,500 |
| Can light and duct boot sealing | $400-$1,200 |
| Attic hatch sealing and insulation | $150-$400 |
Is air sealing really worth it in Houston?
Yes, and it’s usually the best first-dollar spend. Sealing the attic floor reduces both heat gain and humidity intrusion, which directly cuts cooling load and improves indoor air quality. Call (866) 751-4428 for an attic assessment.
Should I air seal before or after adding insulation in Houston?
Before, always. Blowing insulation over unsealed leaks means the insulation filters the air instead of stopping it, and you lose much of the benefit. We air seal first on every Houston attic job. Call (866) 751-4428.
Wall Insulation in Houston
Wall insulation in Houston is the retrofit that separates comfortable houses from hot-boxes, especially on 1960s-1990s ranch homes in Meyerland, Clear Lake, and the Energy Corridor where wall cavities were often left empty or under-filled. The Houston-specific caveat is vapor drive: in Climate Zone 2A, moisture moves inward during summer, so any wall insulation strategy must avoid interior-side vapor retarders that trap moisture inside the cavity and feed mold. Our Wall Insulation work is designed around that local reality, using materials and placement that let wall assemblies dry outward.
Injection Foam Wall Insulation
Signs you need it
Exterior walls feel warm to the touch in summer, rooms along outside walls stay uncomfortable, or you’ve found empty wall cavities during a renovation.
What it costs in Houston
Injection foam wall insulation in Houston normally runs $3,000-$7,000 for a single-story ranch depending on wall area, siding type, and access.
How we do it
We drill small access holes in each stud bay from the exterior or interior, inject foam that expands to fill the cavity, then patch and finish the holes.
Drill & Fill Wall Insulation
Signs you need it
You have uninsulated 2×4 walls, you can hear outside noise clearly, or your AC bill stays high even after an attic upgrade.
What it costs in Houston
Drill-and-fill wall insulation in Houston typically runs $2,500-$6,000 per floor, with the final number depending on how many stud bays are empty.
How we do it
We remove a strip of siding or drill through the interior drywall, blow dense-pack cellulose or fiberglass into each cavity, monitor fill pressure, and close the wall back up.
What Wall Insulation Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Injection foam wall insulation (single story) | $3,000-$7,000 |
| Drill-and-fill wall insulation (per floor) | $2,500-$6,000 |
| Exterior wall insulation (new construction) | $1,500-$3,500 |
| Interior wall soundproofing | $800-$2,500 |
Why is vapor retarder placement different in Houston walls?
Houston’s summer vapor drive moves inward: hot humid air pushes toward the cool interior. A vapor retarder on the interior side traps moisture inside the wall cavity and feeds mold. We detail wall assemblies for Climate Zone 2A, which is the opposite of northern practice. Call (866) 751-4428 for a wall assessment.
Can you insulate the walls without tearing out my drywall?
Yes. Drill-and-fill and injection foam both work from small access holes that get patched after, so your drywall stays up. It’s the standard retrofit approach for Houston’s empty-cavity ranch homes. Call (866) 751-4428 for an estimate.
Attic Cleaning & Rodent Proofing in Houston
Attic cleaning and rodent proofing in Houston is about more than scratching sounds in the ceiling. Houston’s warm climate supports year-round rodent and wildlife activity, and once animals get into an attic they contaminate insulation with droppings and urine, chew through wiring, and destroy the thermal layer. Our Attic Cleaning & Rodent Proofing work starts with a full exclusion pass, then removes contaminated material, sanitizes the space, and restores insulation so your attic is clean, dry, and sealed against re-entry.
Attic Cleanout
Signs you need it
You hear scratching or thumping at night, see droppings in the attic, or find shredded insulation and chewed wiring.
What it costs in Houston
An attic cleanout in Houston usually runs $800-$2,500 depending on contamination level, attic size, and whether we’re removing insulation or just debris and droppings.
How we do it
We remove contaminated insulation and debris with a contained vacuum system, bag everything for disposal, and inspect the full attic for entry points and wiring damage.
Rodent Proofing & Exclusion
Signs you need it
Animals are entering through soffit gaps, roof intersections, or eave vents, and you’ve had repeat activity despite traps or bait.
What it costs in Houston
Rodent proofing and exclusion in Houston typically runs $600-$2,000 depending on the number and type of entry points and the repairs needed to close them permanently.
How we do it
We seal every entry point with steel mesh, hardware cloth, and foam where appropriate, then install one-way doors if needed so animals leave but can’t get back in.
What Attic Cleaning & Rodent Proofing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Attic cleanout and debris removal | $800-$2,500 |
| Attic sanitizing and decontamination | $1,000-$3,000 |
| Rodent proofing and exclusion | $600-$2,000 |
| Full attic restoration (clean, sanitize, insulate) | $3,000-$7,500 |
Does attic rodent damage require new insulation in Houston?
Usually yes. Rodent urine and droppings contaminate insulation and it can’t be cleaned in place; it has to be removed and replaced. The nest material and matted fiberglass also lose almost all R-value. Call (866) 751-4428 for a damage assessment.
Will sealing my attic make Houston’s heat worse?
No. Attic ventilation and air sealing are different things. We seal entry points but keep ridge, soffit, and eave vents functional so the attic still breathes in Houston’s climate. The goal is keeping animals out, not trapping heat. Call (866) 751-4428 for specifics.
Home Energy Audit in Houston
A home energy audit in Houston is the fastest way to find out whether your discomfort is coming from the attic, the ducts, the walls, or the crawl space. With cooling load dominating 9 months of the year, Houston audits look different than northern ones: we’re measuring heat gain, duct leakage, and humidity intrusion, not just heat loss. Our Home Energy Audit uses a blower door, thermal imaging, and duct testing to give you a ranked list of fixes that will actually move the needle on your electric bill.
Blower Door Test
Signs you need it
Your house feels drafty even with windows closed, rooms are unevenly conditioned, or your AC runs nonstop through the Houston summer.
What it costs in Houston
A blower door test in Houston runs $300-$600 as part of a full home energy audit, or as a standalone measurement before and after retrofit work.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to a standard pressure, and measure total air leakage in cubic feet per minute, then locate the leaks.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls or ceilings, you have unexplained hot or cold spots, or you want verification after an insulation job.
What it costs in Houston
Thermal imaging as part of a Houston home energy audit runs $200-$500, and it’s the most direct way to see where the conditioned air is escaping.
How we do it
We scan walls, ceilings, and floors with an infrared camera while the house is under pressure, which makes missing insulation and air leaks show up as clear thermal anomalies.
What Home Energy Audit Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Full home energy audit (blower door + thermal imaging) | $500-$1,200 |
| Blower door test (standalone) | $300-$600 |
| Thermal imaging inspection | $200-$500 |
| Duct leakage test | $250-$500 |
What does a Houston energy audit actually show me?
You get a ranked list of problems: where air leaks are, how much your ducts leak, which walls or ceilings are under-insulated, and what each fix would cost and save. It turns guesswork into a plan. Call (866) 751-4428 to schedule one.
Should I get an audit before or after buying an older Houston home?
Before you settle on upgrades, and ideally before you buy. An audit on a 1960s-1990s ranch in Houston often reveals empty wall cavities, leaky ducts, and an attic that’s never been properly sealed. Knowing those facts prevents spending money on the wrong fix. Call (866) 751-4428.

FAQs About Insulation in Houston, TX
How quickly can you schedule an insulation job in Houston?
We typically schedule inspections within a few business days of your call, and most crawl space, attic, and wall jobs are completed within one to two visits. Exact timing depends on current job volume and the scope of work, but we will give you a start date once we have seen the space in person.
Do I need a permit for insulation work here?
Most insulation retrofits in Houston do not require a standalone permit since we are adding material to an existing structure rather than changing it. Any electrical work uncovered during a job, such as old wiring near can lights, is handled and inspected separately.
How does the written estimate process work?
We inspect your attic, crawl space, or walls in person, measure square footage, and check for moisture, pests, or the condition of any existing insulation. From that visit we write a fixed price before any work starts, so you know the total cost upfront with no changes added later.
Which areas near Houston do you cover?
Beyond the city itself, we also serve nearby communities including Spring, The Woodlands, Katy, Pearland, Humble, and Sugar Land. If your home falls in one of these service areas, we can schedule the same inspection and written estimate process we use here.
What happens to my old insulation before new material goes in?
If your existing insulation is compressed, contaminated, or contains vermiculite, we remove and dispose of it before installing anything new. If it is simply thin but otherwise in good condition, we can often add new material on top of it, which keeps the job faster and less expensive.
