Insulation in Charlotte, NC
Warmline Insulation Co. handles the full spectrum of insulation and home-performance work in Charlotte, NC, with crawl space encapsulation and vapor barrier installation as our most-called-for specialty. Charlotte’s mixed-humid climate and the tens of thousands of builder-grade tract homes raised between the late 1980s and mid-2000s create problems general contractors don’t catch: damp, vented crawl spaces feeding moisture into living areas, R-19 attics far below today’s standards, and reversed vapor drive that makes the wrong insulation a liability. Call (855) 657-3403 and a live person answers, 24/7.
Why Charlotte Homes Are Different
Charlotte sits in IECC Climate Zone 3A, mixed-humid. That means seasonal vapor drive reverses direction: moisture pushes inward during our long, hot summers and outward during short, damp winters. A Northern-style interior poly vapor barrier that works fine in Minnesota becomes a moisture trap here, condensing water inside wall cavities and breeding mold. We see this failure regularly in homes where out-of-state contractors installed the wrong assembly.
The housing stock compounds the problem. Most of Charlotte’s growth happened fast, between roughly 1988 and 2008, producing sprawling wood-frame subdivisions across Ballantyne, Steele Creek, Huntersville, and Matthews. Those homes were built to the minimum code of their era: R-19 attic insulation, fiberglass-batt walls, vented crawl spaces under ranch and split-level plans. Today’s North Carolina code requires R-38 in attics, leaving a massive retrofit backlog. Meanwhile, older inner-ring neighborhoods like Dilworth, NoDa, Plaza Midwood, and the former mill villages of North Charlotte hold 1910s-to-1940s bungalows with balloon-frame walls and little or no original insulation, which need careful dense-pack retrofits rather than simple batts.
Charlotte’s five-plus-month cooling season is the hidden driver behind most insulation calls we get. Unconditioned attic temperatures above 140-150°F degrade fiberglass and aging cellulose, while vented crawl spaces actively pump humid air upward into the house. Our work is about correcting what the climate and the building era combined to create.
Our Main Charlotte Services
Two services dominate the calls we take from Charlotte homeowners: crawl space work and attic insulation. Here’s what each involves locally.
Attic Insulation in Charlotte
Charlotte attics built between the late 1980s and mid-2000s typically hold R-19 fiberglass, and after years of 140°F-plus summers, much of it is compressed, faded, or shifted. Warmline brings those attics to current R-38 standards using blown-in fiberglass or cellulose from Owens Corning, Johns Manville, or GreenFiber. We also air seal the attic floor first, because insulation alone doesn’t stop conditioned air from escaping through the dozens of penetrations hidden in every Charlotte tract home. Most jobs finish in a single visit. Read the full breakdown: Attic Insulation in Charlotte.

Crawl Space Encapsulation & Vapor Barrier in Charlotte
Crawl space encapsulation in Charlotte is the single most effective upgrade for homes with vented crawl spaces, and it matters here more than anywhere because our summer humidity turns every vent into an open door for moisture. The dominant ranch and split-level stock across Mecklenburg County sits on crawl spaces that actively pump humid air into the house, undermining any insulation above them and loading the HVAC system with extra latent load. Our Crawl Space Encapsulation & Vapor Barrier service seals the space completely, controls moisture, and protects the home from below.
Crawl Space Vapor Barrier
Signs you need it
Damp earth smell in the house, elevated indoor humidity in summer, or condensation on ductwork below the floor.
What it costs in Charlotte
Crawl space vapor barrier installation in Charlotte typically runs $1,200-$2,500 depending on square footage and access.
How we do it
We lay a heavy-duty reinforced poly liner across the floor, run it up the walls, and mechanically secure it at piers and seams.
Crawl Space Encapsulation
Signs you need it
Standing water after heavy rain, mold on floor joists, or insulation that’s wet and sagging away from the floor deck.
What it costs in Charlotte
Full crawl space encapsulation in Charlotte falls between $4,500 and $9,000, including vapor barrier, wall insulation, and sealed vents.
How we do it
We seal every vent, install a continuous vapor barrier, insulate the perimeter walls, and add a dehumidifier when humidity testing calls for it.
Crawl Space Cleanout
Signs you need it
Debris, construction scraps, old vapor barrier fragments, or pest droppings left in the space.
What it costs in Charlotte
Crawl space cleanout in Charlotte starts around $500 and rises with the amount of debris and access difficulty.
How we do it
We remove all debris and failed materials, bag and haul everything out, and prep the space for encapsulation or new vapor barrier.
What Crawl Space Encapsulation & Vapor Barrier Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Vapor barrier installation | $1,200 - $2,500 |
| Full encapsulation | $4,500 - $9,000 |
| Crawl space cleanout | $500 - $1,200 |
| Dehumidifier addition | $1,800 - $3,200 |
Does encapsulation help with Charlotte’s summer humidity?
Yes. Encapsulation stops the main moisture source: the exposed earth and open vents. Homes we seal in Charlotte typically see indoor humidity drop 10-20% within a week, and the HVAC system doesn’t have to fight latent load all summer.
Do I need a permit for crawl space encapsulation in Charlotte?
Most crawl space encapsulation and vapor barrier jobs don’t require a permit, but if we’re adding electrical work for a dehumidifier, we’ll handle the permit. We’ll tell you exactly what’s needed before work starts. Call (855) 657-3403 for a free assessment.
Spray Foam Insulation in Charlotte
Spray foam insulation in Charlotte solves two problems at once: it insulates and it air seals. In our mixed-humid climate, that air sealing matters because reversed vapor drive means any air leak is also a moisture leak. The volume-built homes across Ballantyne and Steele Creek have dozens of gaps around top plates, can lights, and dropped soffits that batt insulation never touched, and closed-cell foam stops that airflow cold. Our Spray Foam Insulation crews use Icynene and Demilec foams, installed by trained, uniformed technicians.
Open-Cell Spray Foam
Signs you need it
Rooms that won’t hold temperature, high utility bills, or noise transfer through ceiling and wall assemblies.
What it costs in Charlotte
Open-cell spray foam in Charlotte runs $0.45-$0.80 per board foot installed.
How we do it
We spray a continuous layer onto the attic floor or roof deck, filling gaps and creating a monolithic air barrier.
Closed-Cell Spray Foam
Signs you need it
Moisture intrusion in crawl spaces or rim joists, or a need for structural reinforcement along with insulation in Charlotte’s damp climate.
What it costs in Charlotte
Closed-cell spray foam in Charlotte typically costs $1.10-$1.60 per board foot.
How we do it
We apply foam to the target surface, and it expands to roughly two inches per pass, curing to a rigid, vapor-closed layer.
Rim Joist Spray Foam
Signs you need it
Cold floors near exterior walls, musty smells from the crawl space, or visible gaps around the sill plate.
What it costs in Charlotte
Rim joist spray foaming in Charlotte runs $800-$1,800 for a typical ranch or split-level home.
How we do it
We seal each joist bay with closed-cell foam, cutting off both air leakage and moisture transfer from the crawl space.
What Spray Foam Insulation Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Open-cell spray foam | $0.45 - $0.80 per board foot |
| Closed-cell spray foam | $1.10 - $1.60 per board foot |
| Rim joist spray foam | $800 - $1,800 |
| Garage ceiling spray foam | $1,200 - $2,600 |
Is spray foam worth it in Charlotte’s climate?
Yes, particularly closed-cell foam in crawl spaces and rim joists. Charlotte’s humidity means air leakage is also moisture leakage, and foam is the only insulation that stops both in one pass.
How long does spray foam take to install in Charlotte?
Most rim joist and attic floor jobs finish in a single day. Full roof deck applications may take two days. Call (855) 657-3403 for a same-week estimate.
Blown-In Insulation in Charlotte
Blown-in insulation is the most practical retrofit for Charlotte’s under-insulated tract homes, and it’s the fastest way to bring those R-19 attics in Ballantyne, Matthews, and Steele Creek up to the R-38 the state now requires. Blown-in fiberglass or cellulose fills irregular cavities around trusses and wiring far better than batts ever did, and it’s the most cost-effective upgrade for most Charlotte attics. Our Blown-In Insulation work uses Owens Corning fiberglass and GreenFiber cellulose, applied by background-checked crews.
Blown-In Cellulose
Signs you need it
Thin or settled attic insulation, or rooms that overheat by late afternoon even with the AC running.
What it costs in Charlotte
Blown-in cellulose attic insulation in Charlotte runs $1,100-$2,400 for a typical 1,500-square-foot attic.
How we do it
We air seal the attic floor first, then blow cellulose to the target depth, checking coverage with depth gauges every few feet.
Blown-In Fiberglass
Signs you need it
Existing fiberglass batts flattened or shifted, leaving bare spots in the attic.
What it costs in Charlotte
Blown-in fiberglass in Charlotte typically runs $1,000-$2,200 for a standard attic top-up or full fill.
How we do it
We blow loose-fill fiberglass to the specified depth, fluffing for consistent R-value across the whole attic plane.
Dense-Pack Wall Insulation
Signs you need it
Older homes in Dilworth, NoDa, or Plaza Midwood with empty wall cavities and drafty rooms that stay cold in winter.
What it costs in Charlotte
Dense-pack wall insulation in Charlotte runs $1,800-$4,000 depending on wall area and access from inside or outside.
How we do it
We drill small holes through siding or drywall, dense-pack cellulose into each cavity, then patch and finish.
What Blown-In Insulation Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Blown-in cellulose attic | $1,100 - $2,400 |
| Blown-in fiberglass attic | $1,000 - $2,200 |
| Dense-pack wall insulation | $1,800 - $4,000 |
| Blown-in top-up | $500 - $1,200 |
How much blown-in insulation do Charlotte attics need?
Current North Carolina code calls for R-38 in attics, which is roughly 12-14 inches of blown-in fiberglass or cellulose. Most Charlotte homes built before 2008 sit at R-19 or less.
Can you blow insulation over existing batts in Charlotte?
Usually yes. We inspect first for moisture or pest damage, and if the existing batts are dry and intact, we blow directly over them. Call (855) 657-3403 for a free attic check.
Radiant Barrier Installation in Charlotte
Radiant barrier installation in Charlotte attacks the biggest heat source our homes face: an attic that hits 140-150°F from May through September. A radiant barrier reflects radiant heat before it ever reaches your insulation or your living space, and in Charlotte’s five-plus-month cooling season, that translates into shorter AC runtimes and a cooler second floor. Our Radiant Barrier Installation service installs perforated foil under the roof deck, where it does its best work.
Attic Radiant Barrier
Signs you need it
Second-floor rooms that stay 8-10°F hotter than the main floor, or an attic that feels like an oven by noon.
What it costs in Charlotte
Attic radiant barrier installation in Charlotte runs $1,000-$2,500 for a standard 1,500-square-foot attic.
How we do it
We staple perforated foil to the underside of roof rafters, leaving the ridge and soffit vents open for airflow.
Radiant Barrier Foil
Signs you need it
High attic temperatures despite adequate insulation, or HVAC ducts running through a hot attic space.
What it costs in Charlotte
Radiant barrier foil in Charlotte typically costs $0.35-$0.60 per square foot of covered roof deck.
How we do it
We roll and staple the foil in continuous runs, overlapping seams and keeping it taut for best reflective performance.
Radiant Barrier & Ventilation
Signs you need it
Attic heat that never seems to dissipate even at night, or a roof that’s visibly hot from the interior.
What it costs in Charlotte
Combined radiant barrier and ventilation upgrades in Charlotte run $1,600-$3,400 depending on roof size.
How we do it
We install the barrier and confirm or upgrade ridge, soffit, and gable vents so reflected heat has somewhere to exit.
What Radiant Barrier Installation Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Attic radiant barrier | $1,000 - $2,500 |
| Radiant barrier foil | $0.35 - $0.60 per sq ft |
| Radiant barrier roof deck | $1,200 - $2,800 |
| Radiant barrier & ventilation | $1,600 - $3,400 |
Does radiant barrier work in Charlotte’s climate?
Yes, and it’s one of the best ROI upgrades for Charlotte specifically because our cooling season is long and our attics get extremely hot. Expect the biggest difference in upstairs rooms and homes with ductwork in the attic.
Will radiant barrier replace blown-in insulation in Charlotte?
No. Radiant barrier reflects heat, but insulation still slows conductive heat. We typically recommend both, with radiant barrier above and blown-in insulation below. Call (855) 657-3403 for a combined estimate.
Insulation Removal & Replacement in Charlotte
Insulation removal and replacement in Charlotte is usually a correction, not an upgrade. We see attics all over Mecklenburg County where rodent activity, roof leaks, or decades of 140°F heat have turned fiberglass batts into a matted mess that insulates poorly and hides problems. Removing it is the only way to see the attic floor, fix air leaks, and start clean. Our Insulation Removal & Replacement service handles full extraction, disposal, and fresh installation.
Attic Insulation Removal
Signs you need it
Insulation that’s compressed, dirty, matted, or has been saturated by leaks to the point it no longer holds loft.
What it costs in Charlotte
Attic insulation removal in Charlotte runs $1,000-$2,500 for a standard 1,500-square-foot attic.
How we do it
We vacuum out all existing insulation with commercial equipment, bag it, and haul it away, then prep the attic floor.
Contaminated Insulation Removal
Signs you need it
Rodent droppings, urine stains, or nesting material mixed into the insulation, or a strong animal smell in the attic.
What it costs in Charlotte
Contaminated insulation removal in Charlotte typically runs $2,000-$4,500 including sanitizing.
How we do it
We remove all contaminated material under containment, sanitize the space, and treat the attic floor before reinstalling.
Insulation Replacement
Signs you need it
After removal, we replace with clean, code-compliant blown-in fiberglass or cellulose matched to the home’s needs.
What it costs in Charlotte
Insulation replacement in Charlotte runs $1,500-$3,500 for a typical attic after removal and air sealing.
How we do it
We air seal the attic floor, then blow or install new insulation to R-38, with coverage checks every few feet.
What Insulation Removal & Replacement Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Attic insulation removal | $1,000 - $2,500 |
| Contaminated insulation removal | $2,000 - $4,500 |
| Vermiculite removal | $4,000 - $9,000 |
| Insulation replacement | $1,500 - $3,500 |
Do I need to remove old insulation before adding new insulation in Charlotte?
Not always. If the old insulation is dry, uncompressed, and uncontaminated, we can often blow over it. We remove first when there’s moisture, rodent contamination, or the old material is too matted to perform.
Is vermiculite insulation common in Charlotte homes?
It appears occasionally in pre-1960 homes around Dilworth and NoDa. We treat it as potentially asbestos-containing until testing says otherwise, and we never disturb it without proper containment. Call (855) 657-3403 if you suspect vermiculite.
Attic Air Sealing in Charlotte
Attic air sealing in Charlotte is the most underrated insulation job we do, because our long cooling season means every air leak in the attic floor is also a humidity leak. Bath fans, can lights, plumbing chases, and the attic hatch all act as vents between the air-conditioned house and a 140°F attic, and sealing them is the step that makes insulation actually perform. Our Attic Air Sealing crews use foam and caulk to close these gaps before any new insulation goes in.
Attic Floor Air Sealing
Signs you need it
Dusty insulation that’s dark in spots, bathroom exhaust fans that run constantly, or rooms that won’t stay comfortable.
What it costs in Charlotte
Attic floor air sealing in Charlotte runs $600-$1,400 for a typical ranch or two-story home.
How we do it
We move back existing insulation, foam and caulk every penetration through the attic floor, then restore and top up insulation.
Top Plate & Penetration Sealing
Signs you need it
Visible gaps where walls meet the attic, or warm air rising into the attic that you can feel when standing at the hatch.
What it costs in Charlotte
Top plate and penetration sealing in Charlotte typically runs $500-$1,200.
How we do it
We seal the full perimeter where interior walls meet attic framing, plus plumbing and wiring penetrations.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights that get hot to the touch, or supply ducts with visible gaps where they pass through the attic floor.
What it costs in Charlotte
Can light and duct boot sealing in Charlotte runs $300-$800 depending on the number of fixtures.
How we do it
We seal each fixture and duct boot with fire-rated foam or UL-listed covers, stopping air and heat transfer at the source.
What Attic Air Sealing Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Attic floor air sealing | $600 - $1,400 |
| Top plate & penetration sealing | $500 - $1,200 |
| Can light & duct boot sealing | $300 - $800 |
| Attic hatch sealing | $150 - $350 |
Does air sealing reduce Charlotte cooling bills?
Yes, and often measurably. When we seal the attic floor, the AC isn’t fighting a constant draw of 140°F attic air into the house. Most Charlotte homeowners see the biggest difference in upstairs rooms and in their August bills.
Should I air seal before adding attic insulation in Charlotte?
Definitely. Insulation over unsealed penetrations is like wearing a sweater with holes in it. We always seal first, then insulate. Call (855) 657-3403 for a free assessment.
Wall Insulation in Charlotte
Wall insulation in Charlotte splits into two distinct calls: the volume-built homes from the 1988-2008 era with fiberglass batts that may be okay but add little, and the pre-1940 houses in Dilworth, Plaza Midwood, and the old mill villages with empty walls and no insulation at all. Both respond to different methods, and both matter because Charlotte’s mixed-humid climate means wall assemblies need to breathe correctly while still stopping heat transfer. Our Wall Insulation work is built around that understanding.
Injection Foam Wall Insulation
Signs you need it
Rooms that heat up fast in summer, cold walls in winter, or high bills despite a well-insulated attic.
What it costs in Charlotte
Injection foam wall insulation in Charlotte runs $3,500-$8,000 for a typical single-story home.
How we do it
We drill small holes in the wall, inject slow-rise foam into each cavity, and patch the holes to a clean finish.
Drill & Fill Wall Insulation
Signs you need it
Older Charlotte homes with empty stud cavities, where dense-pack cellulose is the best fit.
What it costs in Charlotte
Drill and fill wall insulation in Charlotte runs $1,800-$4,000 depending on wall area.
How we do it
We drill access holes through siding or drywall, dense-pack cellulose into each cavity, then seal and patch.
Interior Wall Soundproofing
Signs you need it
Noise transfer between rooms, home offices that need quiet, or bedrooms near busy streets like South Boulevard.
What it costs in Charlotte
Interior wall soundproofing in Charlotte typically runs $1,500-$3,500 for a standard wall or two.
How we do it
We install Rockwool or dense-packed material inside interior walls, with acoustic caulk at seams and outlets.
What Wall Insulation Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Injection foam wall insulation | $3,500 - $8,000 |
| Drill & fill wall insulation | $1,800 - $4,000 |
| Exterior wall insulation | $6,000 - $15,000 |
| Interior wall soundproofing | $1,500 - $3,500 |
Which walls need insulation most in Charlotte?
West-facing and south-facing walls, which take the brunt of our afternoon sun, plus any wall with empty cavities in older homes. We’ll find the gaps with an energy audit if you’re not sure.
Can you insulate my walls without tearing out drywall in Charlotte?
Yes, both injection foam and drill-and-fill work through small holes we patch afterward. The process is clean and typically takes one day. Call (855) 657-3403 for a free wall assessment.
Attic Cleaning & Rodent Proofing in Charlotte
Attic cleaning and rodent proofing in Charlotte goes hand in hand with insulation replacement, because the same attics that fill with hot air all summer also attract squirrels and rats looking for shelter. When rodents nest in insulation, they soak it with droppings and urine, and the only real fix is full removal, sanitizing, and sealing every entry point. Our Attic Cleaning & Rodent Proofing service handles the whole sequence, including exterior exclusion work.
Attic Cleanout
Signs you need it
Old insulation, abandoned nesting material, or decades of accumulated dust and debris in the attic.
What it costs in Charlotte
Attic cleanout in Charlotte runs $500-$1,200 for a standard 1,500-square-foot attic.
How we do it
We remove all loose debris, bag and haul it, and leave the attic floor clear for inspection and air sealing.
Attic Sanitizing & Decontamination
Signs you need it
Rodent droppings, urine stains, or lingering odors in the attic or ductwork.
What it costs in Charlotte
Attic sanitizing and decontamination in Charlotte runs $800-$2,000 depending on severity.
How we do it
We treat the attic surfaces with an enzyme-based decontaminant, fog the space, and set it up for fresh insulation.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds at night, chewed wiring, or visible gaps at eaves, gable vents, and soffit edges.
What it costs in Charlotte
Rodent proofing and exclusion in Charlotte typically runs $600-$1,500 including all entry point sealing.
How we do it
We seal every entry point with steel mesh and foam, cap vents, and verify the attic is fully closed.
What Attic Cleaning & Rodent Proofing Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Attic cleanout | $500 - $1,200 |
| Attic sanitizing & decontamination | $800 - $2,000 |
| Rodent proofing & exclusion | $600 - $1,500 |
| Attic restoration | $1,500 - $4,000 |
Will rodents come back after attic cleaning in Charlotte?
Only if they can get back in. That’s why we never clean without proofing, and we never proof without cleaning. The full sequence is what keeps Charlotte attics clear year-round.
Is rodent damage to insulation covered by insurance in Charlotte?
Sometimes. Many Charlotte policies cover the resulting damage, but not the exclusion work. We document everything and give you photos and a report for your claim. Call (855) 657-3403 for help from start to finish.
Home Energy Audit in Charlotte
A home energy audit in Charlotte is the diagnostic starting point that tells us exactly where your house is losing conditioned air, so every insulation dollar goes to the right problem first. For the tract homes across Steele Creek and Ballantyne, that’s usually the attic floor and crawl space; for older bungalows in Dilworth and NoDa, it’s often walls and windows. Our Home Energy Audit is the smartest first step you can take before any retrofit.
Blower Door Test
Signs you need it
High energy bills, drafty rooms, or a house that never seems to hold temperature in any season.
What it costs in Charlotte
A blower door test in Charlotte runs $200-$450 as part of a full energy audit.
How we do it
We mount a calibrated fan in your front door, depressurize the house, and measure exactly how much air leaks in.
Thermal Imaging Inspection
Signs you need it
Nail holes showing through drywall, mystery cold spots, or suspicion that your walls were never insulated.
What it costs in Charlotte
Thermal imaging inspection in Charlotte runs $150-$350, and it’s included in our full home energy audit.
How we do it
We scan every wall, ceiling, and floor with an infrared camera to map missing or failing insulation visually.
Duct Leakage Test
Signs you need it
Dusty rooms, uneven temperatures between floors, or high bills with no obvious cause.
What it costs in Charlotte
Duct leakage testing in Charlotte runs $250-$500 depending on system size and access.
How we do it
We pressurize the duct system and measure how much conditioned air is escaping into the attic or crawl space.
What Home Energy Audit Costs in Charlotte
| Item | Typical range in Charlotte |
|---|---|
| Full home energy audit | $300 - $650 |
| Blower door test alone | $200 - $450 |
| Thermal imaging inspection | $150 - $350 |
| Duct leakage test | $250 - $500 |
How long does a home energy audit take in Charlotte?
Two to three hours for a typical Charlotte home. You’ll get a room-by-room report and a prioritized list of fixes, so you know what to do first and what can wait.
Will Duke Energy or the city of Charlotte rebate an energy audit?
Duke Energy has run occasional audit rebate programs for Charlotte customers in the past, but availability changes. We’ll help you check current programs and apply if one is active. Call (855) 657-3403 for current details.

FAQs About Insulation in Charlotte, NC
How quickly can you schedule insulation work here?
We typically schedule an inspection within a few business days of your call, and most attic, crawl space, or wall jobs start within one to two weeks once we’ve confirmed the scope. Urgent issues, like an exposed attic or a failed vapor barrier, get priority scheduling.
Do I need a permit for insulation work in Charlotte?
Most attic insulation, air sealing, and crawl space work here doesn’t require a separate permit, though requirements can vary by project scope and jurisdiction. If your job does need one, we handle the paperwork before work starts, so you’re covered either way.
How does the written estimate process work?
We walk the attic, crawl space, or walls in person, measure the square footage, and note what condition the existing insulation is in. You get a written estimate with the recommended materials, R-values, and total price before any work begins, so there are no surprises once the crew arrives.
Which nearby areas do you cover?
We also regularly work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If you’re just outside one of those areas, reach out and we’ll confirm whether your address falls within our current service radius.
What happens to my old insulation?
We remove and bag the old material, whether it’s compressed fiberglass, vermiculite, or insulation damaged by rodents, before installing anything new. Contaminated insulation gets disposed of according to local rules, and we sanitize the space so the new material goes into a clean attic or crawl space.

What Charlotte Customers Say
"Upstairs was ten degrees hotter than downstairs every summer. They pulled the attic to bare joists, air-sealed every can light and top plate first, then blew it to R-49. First August in this house where the bedrooms and the living room read the same on the thermostat."
- Marcus Hale"Rodents had been in the attic for years before we bought the place. They vacuumed everything out, sanitized, sealed the entry points with mesh and foam, and only then put new insulation down. Photos of every stage before I paid."
- Darnell Whitfield"They did the energy audit first - blower door and thermal camera - and showed me exactly where the house was leaking before selling me anything. The fix ended up being air sealing plus a modest attic top-up, not the full replacement another company pushed."
