Insulation in Mount Holly, NC

Most insulation work in Mount Holly isn’t new construction. It’s retrofit work on the town’s stock of mill village cottages from roughly 1910 to 1955, which were almost never built with wall cavity insulation and sit over crawl spaces that breathe Catawba River moisture year-round. The single highest-impact job we do here, crawl space encapsulation with a vapor barrier, directly addresses the ground dampness that rots floor systems in these older homes. Call (866) 751-4428 and we’ll tell you what your house actually needs.

Why Mount Holly Homes Are Different

The mill villages along Highland Street, Rankin Avenue, and the blocks near the old textile plants hold hundreds of 800 to 1,200 square foot cottages. These houses share the same construction DNA: pier-and-beam crawl spaces, balloon or platform framing with empty wall cavities, and thin attic floors. Original insulation was usually nothing at all, or a scattered layer of newspaper and rags if anything.

The newer subdivisions west toward Lucia and along the river came after 2000, but even those tract homes were built to late-90s insulation codes, not today’s standards. What really sets Mount Holly apart is the river valley itself. Morning fog and high relative humidity from the Catawba push moisture into open crawl spaces almost daily. We routinely find that in the older mill cottages, ground moisture has saturated any fiber insulation that was added later, and the subfloor under it has started to rot. Scope creep on these jobs is real, and it’s why we quote Mount Holly work differently than we would a job in a Charlotte subdivision. The one down the road, as we say.

Our Main Mount Holly Services

Mount Holly homeowners call us most about two things when they start looking into insulation: what’s going on in the crawl space, and what’s going on in the attic. Here’s how each breaks down.

Attic Insulation in Mount Holly

Mount Holly attics run the gauntlet from open, unfinished mill-era attics with decades of dust and animal activity, to post-2000 homes where the builder blew a thin layer of cellulose and called it done. In the older homes, air leaks from the living space below pull conditioned air out through gaps around chimneys, can lights, and top plates. In the newer ones, June through September heat turns the attic into an oven that radiates straight down through the ceiling. A deep Attic Insulation in Mount Holly job usually combines air sealing, a full top-up of blown-in material, and often some kind of rodent proofing, because mice love old attics. We treat these as system-level fixes, not product swaps.

Crawl Space Encapsulation & Vapor Barrier in Mount Holly

In Mount Holly’s mill village cottages, the crawl space is the root cause of most comfort and durability problems. Ground moisture from the Catawba River valley rises through the soil daily, and an open or poorly vented crawl space lets that moisture reach floor joists, sill plates, and the subfloor. After a few decades, the wood stains, then softens, then fails. Our Crawl Space Encapsulation & Vapor Barrier work addresses this at the source: we line the ground and walls, seal the vents, and condition the space so the house stops wicking damp all year. In the older mill homes, this is almost always the first job we recommend, because everything above it depends on the foundation staying dry.

Crawl Space Vapor Barrier

Signs you need it

Musty odor in the house during humid months, damp floor joists visible from the crawl access, or condensation on ductwork under the house are the classic first signs a vapor barrier is needed.

What it costs in Mount Holly

A 6-mil or 10-mil vapor barrier in a typical 800 to 1,200 sq ft mill cottage crawl space starts around $1,500 to $2,500 depending on access and debris.

How we do it

We remove loose debris, run the liner across the ground and up the foundation walls, seam all overlaps, and mechanically fasten the barrier to the piers and walls so it won’t shift.

Crawl Space Encapsulation

Signs you need it

High indoor humidity, visible fungal growth on joists or sills, a sagging floor over the crawl space, or elevated radon readings mean you likely need full encapsulation, not just a ground cover.

What it costs in Mount Holly

Full encapsulation for an average Mount Holly crawl space typically runs $4,000 to $8,000, including sealing foundation vents and installing a properly sized dehumidifier when needed.

How we do it

We seal vents, install a reinforced vapor barrier on the ground and walls, air-seal the rim joist, and add a crawl-space-rated dehumidifier with a condensate line if moisture history calls for it.

Crawl Space Insulation

Signs you need it

Cold floors directly above the crawl space in winter, drafty interior walls near exterior piers, or water lines that freeze under the house point to missing or degraded underfloor insulation.

What it costs in Mount Holly

Insulating floor joists in a mill cottage crawl space typically falls around $1.50 to $3.00 per square foot of floor area, depending on joist depth and access height.

How we do it

After the crawl space is sealed and dried, we install clean fiberglass batts or board insulation between floor joists, fastening everything so it won’t sag or fall over time.

What Crawl Space Encapsulation & Vapor Barrier Costs in Mount Holly

Item Typical range in Mount Holly
Vapor barrier (6-10 mil, installed) $1,500 - $2,500
Full crawl space encapsulation $4,000 - $8,000
Crawl space dehumidifier (installed) $1,800 - $3,500
Floor joist insulation (per sq ft) $1.50 - $3.00

Does encapsulating a crawl space in Mount Holly help with humidity upstairs?

Yes. In Mount Holly’s river valley climate, most indoor humidity doesn’t come from the attic or the air conditioner. It rises from the ground through the open crawl space. Once the ground is sealed and vents are closed, upstairs humidity typically drops within a week.

Will I need a dehumidifier if I encapsulate my crawl space?

Most homes in Mount Holly do, because the Catawba River valley keeps ambient outdoor humidity high enough that a sealed crawl space can still trap latent moisture without active drying. We size the unit to the square footage and run condensate to a drain or sump.

Spray Foam Insulation in Mount Holly

Spray foam earns its keep in Mount Holly’s split housing market. In the older mill cottages with balloon framing, open stud bays transport air from the crawl space straight to the attic, and foam is often the only realistic way to seal those pathways without gutting plaster walls. In the post-2000 tract homes, rim joists and garage ceilings leak air badly enough that foam pays for itself. Our Spray Foam Insulation crews use open-cell for interior cavities and closed-cell where moisture or structural strength is a concern. It’s a specialty product, and we treat the application carefully.

Rim Joist Spray Foam

Signs you need it

Cold floors at the perimeter of the house in winter and spider webs concentrated around sill plates are both signs the rim joist is leaking outside air into the crawl space or basement.

What it costs in Mount Holly

Rim joist spray foam for a typical Mount Holly crawl space usually lands between $800 and $1,500, depending on linear footage and whether we have to clean the band joist first.

How we do it

We clear the rim joist of old insulation and debris, then apply a continuous layer of closed-cell foam to the band board, sealing the transition where the foundation meets the framing.

Open-Cell Spray Foam

Signs you need it

Rooms that can’t hold a temperature, audible outdoor noise through exterior walls, and unusually high cooling bills point toward open wall cavities that standard batts can’t fill effectively.

What it costs in Mount Holly

Open-cell spray foam on exterior walls in Mount Holly typically runs $1.80 to $3.50 per board foot installed, which is the number to compare against batt or loose-fill quotes.

How we do it

We protect finished surfaces, then spray a continuous layer of open-cell foam into the stud bays, trimming any overflow flush once the foam has cured and re-sealing any access holes.

What Spray Foam Insulation Costs in Mount Holly

Item Typical range in Mount Holly
Rim joist spray foam $800 - $1,500
Open-cell foam (per board foot) $1.80 - $3.50
Closed-cell foam (per board foot) $2.50 - $4.50
Garage ceiling foam (single-car) $1,200 - $2,400

Is spray foam worth the extra cost in Mount Holly’s climate?

For older mill cottages with balloon framing and open cavities, yes. The air sealing alone typically cuts heating and cooling use by 15 to 30 percent, and in Mount Holly’s humid summers, the moisture control in the crawl space and walls adds durability years.

Can you spray foam walls without removing the drywall?

In most cases, yes. We drill small access holes in each stud bay and inject foam through them, then patch. That’s the standard approach for Mount Holly’s mill homes with original plaster walls, and it avoids the expense of a full gut renovation.

Blown-In Insulation in Mount Holly

Mount Holly attics built between 1910 and 1955 typically hold nothing but air and dust at the start of any project, while the post-2000 homes often have a thin layer of builder-grade fiberglass that’s already settled below code. Blown-in insulation is the practical upgrade for both: it fills gaps naturally, covers irregular joist spacing, and can be topped up without touching the existing material. Our Blown-In Insulation crews run GreenFiber cellulose or Johns Manville fiberglass, chosen for the specific attic. The result is a uniform, air-blocking blanket that stops heat from pouring through the ceiling in August.

Blown-In Cellulose

Signs you need it

Rooms that overheat in summer despite a properly sized AC, visible joist tops in the attic floor, or utility bills that spike during the first cold snap suggest the attic needs cellulose blown in.

What it costs in Mount Holly

Blown-in cellulose in a typical Mount Holly attic usually runs $1.20 to $2.00 per square foot installed, depending on depth required and existing material condition.

How we do it

We seal top plates and penetrations first, then blow the cellulose to the specified depth with a calibrated machine, checking density with a spot gauge rather than eyeballing it.

Dense-Pack Wall Insulation

Signs you need it

Exterior walls that feel cold to the touch in winter, rooms along the perimeter of the house that never hold temperature, and original mill-cottage walls with no existing cavity insulation are all dense-pack candidates.

What it costs in Mount Holly

Dense-pack wall insulation in Mount Holly’s older framed walls typically runs $2.00 to $3.50 per square foot of wall area, including access hole drilling and patching.

How we do it

We drill small access holes through each stud bay, blow cellulose at high pressure until the cavity is fully packed, then patch and texture the holes to match surrounding surfaces.

What Blown-In Insulation Costs in Mount Holly

Item Typical range in Mount Holly
Blown-in attic cellulose (per sq ft) $1.20 - $2.00
Blown-in attic fiberglass (per sq ft) $1.00 - $1.80
Dense-pack wall cellulose (per sq ft) $2.00 - $3.50
Attic top-up over existing (per sq ft) $0.80 - $1.40

How much can blown-in insulation save on a Mount Holly utility bill?

Attics account for up to 25 percent of home heat loss and summer heat gain. In a mill cottage with zero attic insulation, a proper blown-in job typically cuts heating and cooling costs by 15 to 25 percent, with the biggest improvement in August and January.

Do you remove old insulation before blowing in new material?

Not always. If the existing material is dry, clean, and free of pest contamination, topping it up is the cheaper and cleaner option. We pull and replace old material only when it’s saturated with moisture, full of rodent droppings, or otherwise compromised.

Radiant Barrier Installation in Mount Holly

Mount Holly’s July and August heat loads put a punishing amount of radiant energy through attic floors, especially on the post-2000 tract homes with dark shingle roofs and shallow attic venting. A radiant barrier installed under the roof deck reflects that heat back toward the roof instead of letting it radiate into the attic. It’s a different tool than insulation, and it works best alongside, not instead of, a proper insulated attic floor. Our Radiant Barrier Installation crews fasten the foil cleanly so it doesn’t sag or interfere with ventilation.

Attic Radiant Barrier

Signs you need it

An attic that feels like an oven whenever the outside temperature tops 90, an upstairs that won’t drop below 78 even at night, and heat radiating through the ceiling after sunset all point to excess radiant gain.

What it costs in Mount Holly

Attic radiant barrier for a typical Mount Holly single-story runs about $0.80 to $1.50 per square foot of attic floor area, including all fasteners and seam tape.

How we do it

We install the reflective foil directly under the roof deck, overlapping each run and taping seams, with enough air gap maintained between the foil and the deck for the barrier to work.

Radiant Barrier Roof Deck

Signs you need it

High attic temperatures measured with a simple thermometer, frequent AC runtime, and shingles that are only ten years old but already showing granule loss are the indicators for a roof-deck radiant barrier.

What it costs in Mount Holly

Roof deck radiant barrier on a Mount Holly home typically comes in between $1,200 and $2,800 for a standard 1,200 to 1,800 sq ft attic.

How we do it

We staple the foil to the underside of the rafters or directly to the roof deck sheathing, leaving air flow channels at eaves and ridge so the attic still ventilates properly.

What Radiant Barrier Installation Costs in Mount Holly

Item Typical range in Mount Holly
Attic radiant barrier (per sq ft) $0.80 - $1.50
Roof deck radiant barrier $1,200 - $2,800
Radiant barrier with attic ventilation fix $2,000 - $4,000

Does a radiant barrier help in winter in Mount Holly?

Some. In winter the barrier reflects heat back down into the living space, reducing the amount of heat lost upward through the ceiling. The bigger benefit in this climate is summer, where attic temperatures can drop by 20 to 30 degrees with a proper barrier.

Do I still need insulation if I install a radiant barrier?

Yes. A radiant barrier only handles radiant heat transfer, not conductive or convective heat. In Mount Holly’s humid hot climate, you need both: insulation at the attic floor to block conduction, and a radiant barrier at the roof deck to reject solar gain.

Insulation Removal & Replacement in Mount Holly

In Mount Holly’s older mill cottages, the insulation that exists today is often worse than nothing. Water has saturated it from failing roofs or open crawl spaces, rodents have tunneled through it, and decades of dust have turned it into a lung irritant. Removal and replacement is the correct first step whenever the existing material is contaminated or compressed past usefulness. Our Insulation Removal & Replacement work involves full vacuum extraction, disposal, and then a clean installation of whatever the space actually calls for. In this town, that’s usually a moisture-first solution.

Attic Insulation Removal

Signs you need it

Evidence of rodent activity in the attic, water stains on the insulation, a musty smell that won’t go away, or material that’s compacted flat all mean the old insulation needs to come out.

What it costs in Mount Holly

Attic insulation removal in a typical Mount Holly home runs $1.50 to $3.00 per square foot, depending on depth, contamination level, and access through the attic hatch.

How we do it

We run a high-powered vacuum hose into the attic, extract all existing insulation to the deck, then bag everything for disposal and air-seal the attic floor before any new material goes down.

Contaminated Insulation Removal

Signs you need it

Droppings visible in the insulation, a strong ammonia odor in the attic, or visible mold on the surface of existing batts are contamination signs that should not be ignored or buried under new material.

What it costs in Mount Holly

Contaminated insulation removal, including sanitizing the attic deck, usually runs $2.00 to $4.00 per square foot in Mount Holly depending on the type and extent of contamination.

How we do it

We remove all contaminated material, HEPA-vacuum the deck and joists, treat the surfaces with a sanitizing agent, and then recommend the right replacement material, never simply covering the problem.

What Insulation Removal & Replacement Costs in Mount Holly

Item Typical range in Mount Holly
Attic insulation removal (per sq ft) $1.50 - $3.00
Contaminated removal with sanitizing (per sq ft) $2.00 - $4.00
Vermiculite removal (per sq ft) $4.00 - $8.00
Replacement blown-in insulation (per sq ft) $1.20 - $2.00

How do I know if my old insulation should be removed or topped up?

If it’s dry, intact, and free of droppings or mold, topping up is usually fine. If it’s wet, matted, full of rodent tunnels, or smells bad, it has to come out. In Mount Holly’s humidity, moisture damage is the most common reason we recommend full removal.

Is vermiculite insulation dangerous?

Some older vermiculite contains asbestos, especially if installed before 1990. We treat any vermiculite as suspect, remove it under controlled conditions with proper containment, and dispose of it through licensed channels. Never disturb vermiculite yourself.

Attic Air Sealing in Mount Holly

Attic air sealing matters in Mount Holly because mill-era homes have dozens of open pathways between the living space and the attic: balloon-framed wall cavities, gaps around chimneys, unsealed can lights, wiring penetrations, and open top plates. In the summer, moist outside air is drawn up through these channels and into the attic, while in winter, heated air escapes upward. Sealing them is the least visible but highest-yield insulation job we do here. Our Attic Air Sealing work pairs with nearly every blown-in or spray foam job to make sure the insulation actually does its job.

Top Plate & Penetration Sealing

Signs you need it

Dust streaks on insulation near wall junctions, drafts that come from wall switches and outlets, and visible wall cavities open to the attic are all signs top plates and penetrations need sealing.

What it costs in Mount Holly

Top plate and penetration sealing in a typical Mount Holly attic runs $400 to $900 for a full home, depending on the number of gaps and the attic accessibility.

How we do it

We clear insulation away from the top plate, seal each stud bay junction with expanding foam or caulk, and then re-bury everything under fresh insulation.

Can Light & Duct Boot Sealing

Signs you need it

Hot air pouring from recessed light fixtures, dust around the trim rings, and supply vents that blow warm air in summer all indicate unsealed can lights and duct boots.

What it costs in Mount Holly

Sealing can lights and duct boots in Mount Holly runs $200 to $600 depending on how many fixtures and registers are in the ceiling.

How we do it

We install rated covers or sealing boxes over each can light, then seal the duct boot to the drywall with mastic or foil tape so conditioned air stays inside the duct and doesn’t leak into the attic.

What Attic Air Sealing Costs in Mount Holly

Item Typical range in Mount Holly
Top plate & penetration sealing $400 - $900
Can light & duct boot sealing $200 - $600
Attic hatch sealing $150 - $350
Full attic air sealing package $800 - $1,800

How much does attic air sealing save on cooling costs?

Air sealing can cut cooling and heating use by 10 to 20 percent on its own, before any new insulation is added. In Mount Holly, where summer humidity makes air leaks more punishing, we usually see the bigger savings in July and August.

Can you air seal an attic without removing all the insulation?

Usually yes. We push the existing insulation aside at each penetration, seal the gap, then pull the insulation back or top it up. Full removal is only needed when the existing material is contaminated or too compacted to move.

Wall Insulation in Mount Holly

Mount Holly’s original mill cottages were built with empty wall cavities, and that’s not an exaggeration. The framing goes up, the siding goes on, the plaster goes in, and nothing goes between. That’s why so many older homes in this town are drafty in January and hot in July, no matter what the thermostat says. Our Wall Insulation work injects insulation into those cavities through small access holes, so original plaster and siding can stay in place. It’s the kind of retrofit that changes how a house feels year-round.

Drill & Fill Wall Insulation

Signs you need it

Exterior walls cold in winter, rooms along the perimeter that never warm up, and an exterior wall that sounds hollow when tapped are signs the cavities are empty and need drill-and-fill insulation.

What it costs in Mount Holly

Drill-and-fill wall insulation in Mount Holly typically runs $2.00 to $3.50 per square foot of wall area, including drilling, filling, and patching each access hole.

How we do it

We drill one access hole per stud bay from inside or outside, blow cellulose or inject foam into the cavity until it’s fully packed, then patch the holes to match the surrounding surface.

Injection Foam Wall Insulation

Signs you need it

Balloon-framed walls with open vertical channels, houses with brick veneer where exterior drilling isn’t practical, and walls with irregular cavity depths all respond well to injection foam.

What it costs in Mount Holly

Injection foam wall insulation in Mount Holly runs $2.50 to $4.50 per square foot, higher than cellulose because the foam expands to fill odd shapes.

How we do it

We inject slow-rise foam through small holes at each cavity, letting it expand to fill every void, then trim and patch the access points for a clean finish.

What Wall Insulation Costs in Mount Holly

Item Typical range in Mount Holly
Drill & fill cellulose (per sq ft) $2.00 - $3.50
Injection foam (per sq ft) $2.50 - $4.50
Exterior wall insulation (per sq ft) $3.00 - $6.00
Interior wall soundproofing (per sq ft) $2.00 - $4.00

Will wall insulation damage my original plaster or siding?

No, and that’s the point of drill-and-fill. The access holes are small, and we patch them carefully. On the exterior we work from the inside whenever plaster is original, specifically to avoid disturbing old siding that’s still in good shape.

Can you insulate balloon-framed walls on a Mount Holly mill cottage?

Yes, and balloon framing is actually one of the easier retrofits because the wall cavities run continuously from the sill to the attic. We can fill the entire channel from either the attic or the basement without opening the wall.

Attic Cleaning & Rodent Proofing in Mount Holly

Mount Holly’s older housing stock came with attics that were never designed to be sealed. Gable vents, open soffits, and gaps around the roofline make them easy entry points for mice, squirrels, and the occasional raccoon, especially in the mill village neighborhoods where mature trees touch roofs. Animals chew wiring, tear up insulation, and leave droppings that create a genuine health hazard. Our Attic Cleaning & Rodent Proofing work removes the mess, sanitizes the space, and blocks the entry points so it doesn’t happen again.

Rodent Proofing & Exclusion

Signs you need it

Scratching noises in the ceiling at night, droppings in the attic, chewed wiring, or grease marks along the roofline are the direct evidence that rodents are using your attic as a highway.

What it costs in Mount Holly

Rodent proofing and exclusion for a typical Mount Holly attic runs $500 to $1,500 depending on how many entry points need sealing and how much trim has to be replaced.

How we do it

We find every possible entry point, close the paths animals use with metal mesh and sealant they can’t chew through, and then check that ventilation still works properly.

Attic Sanitizing & Decontamination

Signs you need it

A persistent ammonia odor from the attic, visible droppings or urine stains on the decking, or an existing rodent problem that’s been resolved all call for sanitizing before re-insulating.

What it costs in Mount Holly

Attic sanitizing and decontamination typically runs $400 to $1,200 depending on attic size and the extent of surface contamination.

How we do it

We remove contaminated material, HEPA-vacuum all surfaces, apply a hospital-grade antimicrobial treatment to the deck and framing, and then run an odor neutralizer so the space is truly clean.

What Attic Cleaning & Rodent Proofing Costs in Mount Holly

Item Typical range in Mount Holly
Rodent proofing & exclusion $500 - $1,500
Attic sanitizing & decontamination $400 - $1,200
Attic cleanout (full removal) $800 - $2,000
Attic restoration package $1,500 - $3,500

Do I need to clean the attic before new insulation goes in?

If there’s any sign of rodent activity, yes. New insulation over contaminated material just traps the odor and the bacteria. In Mount Holly’s older homes, we almost always recommend cleaning and proofing before we blow in fresh insulation.

How do you keep animals from coming back after proofing?

We use metal mesh and hardened sealants that rodents can’t gnaw through, and we check every roof penetration, gable vent, and soffit gap. Then we walk the roofline from outside to confirm nothing is left open. The goal is a permanent closure, not a temporary patch.

Home Energy Audit in Mount Holly

In Mount Holly’s mix of 1920s mill cottages and post-2000 tract homes, an energy audit is the fastest way to find out where your money leaks. Audits measure air leakage, check insulation levels, scan for thermal bridging, and test duct performance, then rank the fixes by payback. Our Home Energy Audit gives Mount Holly homeowners a prioritized list, not a sales pitch. We’ll tell you what’s worth doing and what isn’t, in plain language, before you spend a dollar on insulation.

Blower Door Test

Signs you need it

Rooms that won’t hold temperature, unusually high energy bills, or an inability to keep out summer humidity despite a properly sized HVAC system are all reasons to test the home’s actual air leakage rate.

What it costs in Mount Holly

A professional blower door test in Mount Holly typically runs $200 to $400 as part of a full energy audit, sometimes less when bundled with insulation work.

How we do it

We seal a calibrated fan into an exterior door frame, depressurize the house, and measure exactly how many cubic feet per minute of air leak through the shell and where.

Thermal Imaging Inspection

Signs you need it

Cold spots on walls or ceilings in winter, hot rooms in summer, and unexplained mold or moisture on surfaces all warrant an infrared scan to find what’s happening inside the cavities.

What it costs in Mount Holly

Thermal imaging as part of a Mount Holly energy audit runs $150 to $300 when added to a blower door test and full insulation inspection.

How we do it

We walk the home with an infrared camera while the blower door is running, mapping temperature differences across walls, ceilings, floors, and ducts, then photograph the problem areas for our written report.

What Home Energy Audit Costs in Mount Holly

Item Typical range in Mount Holly
Full home energy audit $300 - $600
Blower door test (standalone) $200 - $400
Thermal imaging inspection (add-on) $150 - $300
Duct leakage test $150 - $350

How long does a home energy audit take in Mount Holly?

Most full audits take two to three hours for a typical Mill-era cottage or post-2000 ranch. The blower door runs for about 30 minutes, the thermal scan takes another 30, and the insulation and duct inspection fill the rest.

Will an energy audit tell me which insulation job to do first?

Yes, that’s exactly what it’s for. Our written report ranks the fixes by payback period, so you’ll know whether to start with the attic, the crawl space, or the walls, and which job will make the biggest difference for your Mount Holly house.

FAQs About Insulation in Mount Holly, NC

How quickly can you schedule insulation work in Mount Holly?

We typically schedule estimates within a few days, and most attic or crawl space jobs are completed in a single day. Mill cottages with tight pier-and-beam crawl spaces sometimes take a bit longer because of the limited access underneath the house.

Do I need a permit for insulation work?

Most insulation work, including attic top-ups, air sealing, and rim joist foam, does not require a separate permit. Morning fog and humidity off the Catawba push moisture into open crawl spaces here, so vapor management matters as much as R-value.

How does your written estimate work?

We inspect the attic, crawl space, or walls in person and provide a written estimate with the full scope and price before any work begins. That price stays fixed unless you request additional work once we’re on site.

Do you serve areas near Mount Holly?

Yes, we also cover the surrounding communities around Mount Holly, so homes just outside the city line can typically get the same estimate, scheduling, and installation process we use for jobs inside the city, without any difference in how we price or schedule the work.

What happens to my old insulation?

We remove and dispose of old, compressed, or contaminated insulation before installing anything new, whether that’s degraded batts, damaged blown-in material, or vermiculite that needs special handling. Removal is priced separately from new insulation so there are no surprises once we start.

- 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."
