Why Lewisville Homes Are Different
Lewisville’s residential core was largely built during the 1980s DFW suburb boom under Texas’s then-minimal energy codes. A high concentration of 35-45-year-old homes carry original, compressed fiberglass batt insulation rated R-19 to R-30 that has settled and lost effectiveness, well below current IECC requirements. The February 2021 Winter Storm Uri then exposed thousands of these same homes’ attic-run water lines as dangerously unprotected. Insulation crews working Lewisville now routinely combine pipe-run insulation with attic top-off retrofits as a single job.
The dominant stock is 1980s-1990s brick-veneer tract homes built during the rapid I-35E corridor expansion, most with vented attics, slab-on-grade foundations, and builder-grade fiberglass batts now 30-40 years old and compressed significantly. Older pockets near Old Town Lewisville include 1950s-1960s homes with little to no wall insulation and undersized attic coverage. Lewisville sits in the hot-humid/mixed transition zone of North Texas, where attic temperatures routinely exceed 140°F in July and August, making degraded attic insulation disproportionately costly in cooling bills. The same homes then proved catastrophically under-insulated during Winter Storm Uri’s sustained sub-teen temperatures.
One more Lewisville-specific detail matters: homes in established subdivisions east of I-35E, areas like Timber Creek and the neighborhoods adjacent to Castle Hills, often have attic HVAC ductwork wrapped in original mylar-faced flex insulation from the 1980s that has separated at joints. That creates energy loss and condensation points that undermine any new blown-in insulation added above. Our crews audit duct wrap before quoting an attic job here.
Our Main Lewisville Services
Most Lewisville homeowners call us first about two things: attic insulation that has stopped doing its job and crawl spaces that need encapsulation. Here’s what each involves locally.
Attic Insulation in Lewisville
Lewisville attics regularly hit 140°F in summer, and the original R-19 to R-30 fiberglass batts in 1980s homes have compressed to a fraction of their rated performance. We inspect the existing coverage, check duct wrap condition, and recommend either a top-off or full removal and replacement. Winter Storm Uri proved these attics need serious protection, not just a quick add. Most jobs are done in one visit. Learn more about our Attic Insulation in Lewisville page.

Crawl Space Encapsulation & Vapor Barrier in Lewisville
Crawl space encapsulation in Lewisville is the single most effective fix for homes with persistent musty odors, buckled hardwood, or elevated indoor humidity, and most jobs run $3,800-$7,500 depending on square footage and access. The slab-on-grade construction era left many local homes with vented crawl spaces that pull North Texas humidity straight into the building envelope. Our Crawl Space Encapsulation & Vapor Barrier service seals the space, dries it out, and protects the framing.
Crawl Space Vapor Barrier
Signs you need it
You smell damp earth or mildew when the HVAC runs, or you see condensation on crawl space walls and exposed ground in summer.
What it costs in Lewisville
A crawl space vapor barrier in Lewisville typically runs $1,800-$3,200 for a standard 1,200-1,800 square foot crawl space.
How we do it
We lay a 12-mil reinforced polyethylene barrier across the entire floor, overlap and seal the seams, and run it up the foundation walls, then secure and tape the edges.
Crawl Space Encapsulation
Signs you need it
Your floors feel warm and humid in summer, your energy bills have crept up, or you’ve seen mold on floor joists.
What it costs in Lewisville
Full encapsulation in Lewisville, including walls, joist rims, and a sealed door, typically costs $3,800-$7,500 for most homes.
How we do it
We seal the vents, install the vapor barrier across floor and walls, insulate the rim joists, and add a dehumidifier if the space needs active drying.
Crawl Space Moisture Control
Signs you need it
You find efflorescence on block walls, rust on HVAC registers, or your crawl space has standing water after heavy rains.
What it costs in Lewisville
Moisture control solutions in Lewisville, including drainage matting and sump pump when needed, generally run $2,200-$5,000.
How we do it
We identify the moisture source first, then install drainage matting, a perimeter drain, or a sump pump along with the vapor barrier and sealing.
What Crawl Space Encapsulation & Vapor Barrier Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Crawl space vapor barrier (floor only) | $1,800-$3,200 |
| Full crawl space encapsulation | $3,800-$7,500 |
| Moisture control with sump pump | $2,200-$5,000 |
| Dehumidifier add-on | $1,200-$2,800 |
How long does crawl space encapsulation take in Lewisville?
Crews can complete most Lewisville crawl spaces in one day, though larger or wetter spaces may run to two. We schedule the work so you’re not disrupted more than necessary, and scheduling is flexible around your week.
Does encapsulation help with Lewisville’s summer humidity?
Yes. Sealing the crawl space stops humid North Texas air from entering through floor joists and duct work. Most homeowners notice lower indoor humidity within a few days and more consistent indoor temperatures. Call (855) 657-3403 to schedule a crawl space inspection.
Spray Foam Insulation in Lewisville
Spray foam insulation in Lewisville works harder than any other material in the local climate: it seals and insulates in one pass, which matters when attics hit 140°F and winter storms drop temperatures below freezing. Whether open-cell or closed-cell, spray foam also air-seals, reducing the stack effect that pulls hot, humid air into these 1980s homes. Our Spray Foam Insulation team installs both types, with brands like Demilec and Icynene.
Open-Cell Spray Foam
Signs you need it
Your upstairs rooms run 8-10°F warmer than downstairs in summer, or you feel drafts near ceiling fixtures and attic stairs.
What it costs in Lewisville
Open-cell spray foam in Lewisville attics typically runs $1.50-$2.50 per board foot installed, or $4,500-$8,000 for a standard 1,500 square foot attic.
How we do it
We clean the surfaces, prep with masking and ventilation, then spray a continuous foam layer across the roofline to create the air and thermal barrier.
Closed-Cell Spray Foam
Signs you need it
You have a crawl space or rim joist area with high moisture, or you want maximum R-value in the thinnest profile for walls.
What it costs in Lewisville
Closed-cell spray foam in Lewisville costs $2.50-$4.00 per board foot, with most full attic jobs landing between $7,000-$13,000.
How we do it
We apply closed-cell foam to the roofline, rim joists, or foundation walls. It’s denser and acts as both vapor retarder and structural reinforcement.
What Spray Foam Insulation Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Open-cell attic spray foam | $1.50-$2.50 per board foot |
| Closed-cell attic spray foam | $2.50-$4.00 per board foot |
| Rim joist spray foam (per home) | $800-$2,000 |
| Garage ceiling spray foam | $1,200-$3,000 |
Does spray foam work in Lewisville’s unvented attics?
Yes, and it’s often the right choice. Our crews check the existing ductwork first; in many Lewisville homes, the original 1980s duct wrap has failed, and foam at the roofline solves both the thermal and air-leakage problem. Call (855) 657-3403 for a site assessment.
Can you spray foam the joist rims in a 1980s Lewisville slab home?
Absolutely. Rim joist foam is one of the fastest air-sealing wins for slab-on-grade homes in Lewisville, often cutting air leakage by double digits. Most rim joist jobs are done in one visit.
Blown-In Insulation in Lewisville
Blown-in insulation is the most common retrofit for Lewisville attics, and with the original R-19 to R-30 batts compressed to maybe R-10, a top-off to R-38 or R-49 is a high-return fix for these 1980s homes. We use Johns Manville and Knauf fiberglass or GreenFiber cellulose, applied over existing batts once we’ve checked for duct leaks and air bypasses. Our Blown-In Insulation crew handles both top-offs and full replacements.
Blown-In Fiberglass
Signs you need it
Your attic insulation looks flat and patchy, or your upstairs has hot and cold spots despite the HVAC running consistently.
What it costs in Lewisville
Blown-in fiberglass in Lewisville attics typically costs $1,800-$3,500 to bring an average attic to R-38.
How we do it
We seal bypasses first, then blow fiberglass to the correct depth with an even, continuous layer. The material settles slightly, so we account for that.
Blown-In Cellulose
Signs you need it
You want a dense, sound-dampening, fire-retardant layer in the attic or walls, or you’re replacing old, thin insulation.
What it costs in Lewisville
Blown-in cellulose in Lewisville attics runs $2,000-$4,200 for a typical home, and dense-pack wall jobs run $2,500-$5,500.
How we do it
We use GreenFiber cellulose, blowing it into the attic or dense-packing walls through small holes that are then patched. The material resists air movement and performs well in high heat.
What Blown-In Insulation Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Blown-in fiberglass attic to R-38 | $1,800-$3,500 |
| Blown-in cellulose attic to R-38 | $2,000-$4,200 |
| Blown-in top-up over existing batts | $1,200-$2,800 |
| Dense-pack wall insulation | $2,500-$5,500 |
Can you blow insulation over the existing batt in my Lewisville attic?
Yes, if the existing batt is dry and not moldy. We check for failing duct wrap and air leaks first, since blowing over a leaky attic wastes material. Most top-off jobs in Lewisville are done the same day.
What R-value should my Lewisville attic have?
Current IECC guidance for North Texas is R-38 to R-60, depending on the existing material. Most 1980s Lewisville homes sit at R-10 to R-20 in practice, so there’s a meaningful gap. A free attic inspection will tell you exactly where you stand.
Radiant Barrier Installation in Lewisville
Radiant barrier installation in Lewisville targets the single biggest summer heat load: the roof deck, which radiates down into attic insulation and the rooms below when attic temperatures pass 140°F. A radiant barrier reflects that heat before it penetrates the living space, which is why it’s such a high-impact retrofit for Lewisville’s long, hot cooling season. Our Radiant Barrier Installation team installs foil barriers on the attic rafters as a complement to, not a replacement for, attic insulation.
Attic Radiant Barrier
Signs you need it
Your attic is unbearably hot even on mild days, or your air conditioner runs almost constantly in July and August.
What it costs in Lewisville
An attic radiant barrier in Lewisville typically costs $1,500-$3,000 for an average 1,500-2,000 square foot attic.
How we do it
We staple a reinforced foil barrier to the underside of the roof rafters, leaving an air gap below the roof deck for the reflection to work properly.
Radiant Barrier & Ventilation
Signs you need it
Your attic traps heat despite working soffit and ridge vents, or your roof deck feels like a radiator when you’re up there.
What it costs in Lewisville
Combined radiant barrier plus ventilation upgrades in Lewisville run $2,200-$4,200 depending on attic size and vent count.
How we do it
We assess airflow first, add soffit baffles or ridge vent if needed, then install the radiant barrier. The two systems work together to keep the attic cooler.
What Radiant Barrier Installation Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Attic radiant barrier | $1,500-$3,000 |
| Radiant barrier + ventilation | $2,200-$4,200 |
| Roof deck radiant barrier (new roof) | $1,800-$3,600 |
| Garage ceiling radiant barrier | $500-$1,200 |
Does a radiant barrier make sense in Lewisville’s climate?
Yes, especially for vented attics. In Lewisville, where attics exceed 140°F repeatedly each summer, a radiant barrier cuts the heat radiated into the insulation and ceiling below. It’s one of the most cost-effective summer cooling measures for 1980s brick-veneer homes.
Can you combine radiant barrier with blown-in insulation?
You should. Radiant barrier handles the radiant heat from the roof deck, while blown-in insulation handles conductive heat. Together they reduce both the peak attic temperature and the heat that migrates through the ceiling. Call (855) 657-3403 for a combined quote.
Insulation Removal & Replacement in Lewisville
Insulation removal in Lewisville is often a necessary first step before any new attic or wall work, because 30-40-year-old fiberglass batts are frequently compressed, dusty, and sometimes contaminated by rodent activity or moisture. Replacing it rather than topping it off gives you a clean surface and a known R-value. Our Insulation Removal & Replacement team does full vacuum removal, sanitizing, and fresh installation, most often in a single visit.
Attic Insulation Removal
Signs you need it
You’re doing a full attic renovation, or the existing insulation has been flattened by decades of foot traffic and lost its loft.
What it costs in Lewisville
Attic insulation removal in Lewisville typically runs $1,500-$3,500 for a standard home, before new insulation is installed.
How we do it
We run a commercial vacuum line to a truck-mounted HEPA filter, pull out the old material, and bag it. No dust fills the living space.
Contaminated Insulation Removal
Signs you need it
You find droppings, nesting material, or a urine smell in the insulation, or there’s visible mold on the attic floor.
What it costs in Lewisville
Contaminated insulation removal in Lewisville runs $2,000-$5,000, including sanitizing and deodorizing after removal.
How we do it
We remove all affected material, treat the surfaces with an antimicrobial agent, and then install fresh insulation. The job also includes sealing entry points if rodents were present.
What Insulation Removal & Replacement Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Attic insulation removal only | $1,500-$3,500 |
| Contaminated insulation removal | $2,000-$5,000 |
| Full removal + new blown-in | $3,500-$7,000 |
| Old vermiculite removal | $3,000-$8,000+ |
Do I need to remove old insulation before adding new in Lewisville?
Not always. If the existing material is dry, not moldy, and not rodent-compromised, a top-off mid-job saves money. But if moisture or pests are present, removal is safer and smarter. We’ll give you an honest recommendation after inspection.
Can you remove vermiculite insulation in a Lewisville home?
Yes, with proper protocol. Older Lewisville homes near Old Town may have vermiculite, which can contain asbestos. We follow containment and disposal procedures and recommend testing before any disturbance. Call (855) 657-3403 to discuss your situation.
Attic Air Sealing in Lewisville
Attic air sealing in Lewisville is the quiet but essential step that makes every other insulation measure work better: no point paying for R-38 if your air-handled air is leaking through top plates, can lights, and duct boots into the attic. The 1980s brick-veneer homes here are notorious for unsealed penetrations that let cooled air escape and pull humid outside air in. Our Attic Air Sealing work tightens the building envelope before we insulate or after we remove old material.
Attic Floor Air Sealing
Signs you need it
Your upstairs is dusty, drafts appear around ceiling fixtures, or your home’s air feels stale despite the AC running.
What it costs in Lewisville
Full attic floor air sealing in Lewisville typically costs $1,000-$2,500 depending on attic size and penetration count.
How we do it
We pull back existing insulation, seal every wire chase, plumbing penetration, top plate, and gap with foam or caulk, then re-install the insulation to the correct depth.
Can Light & Duct Boot Sealing
Signs you need it
You see daylight or feel airflow around recessed lights, or the HVAC registers wobble and leak at the ceiling.
What it costs in Lewisville
Can light and duct boot sealing in Lewisville runs $400-$1,200 for a typical home, depending on fixture and boot count.
How we do it
We seal around each fixture with high-temperature caulk or covers, then seal the duct boots with mastic and tape so conditioned air doesn’t escape into the attic.
What Attic Air Sealing Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Attic floor air sealing (full) | $1,000-$2,500 |
| Can light sealing | $400-$1,200 |
| Top plate & penetration sealing | $800-$2,000 |
| Attic hatch sealing | $150-$400 |
Does air sealing help in Winter Storm Uri-type cold snaps?
Yes. Sealing the attic floor reduces the warm air escaping in winter, which is exactly the problem that made Lewisville homes so vulnerable during Uri. The same seals also reduce summer humidity ingress. Call (855) 657-3403 to schedule an air sealing assessment.
Will air sealing make my Lewisville home too tight?
For a typical 1980s Lewisville home, no. These homes leak far more than modern standards, and sealing brings them closer to healthy air exchange rates. In a few cases, we may recommend adding mechanical ventilation, which we’ll flag in the estimate.
Wall Insulation in Lewisville
Wall insulation in Lewisville is most often an injection or drill-and-fill job, because knocking down drywall is rarely worth it; the focus instead is on the many older 1950s-1960s homes near Old Town that have little to no insulation in the wall cavity. Once those walls are filled, street noise drops, rooms hold temperature better, and the HVAC doesn’t run as hard. Our Wall Insulation team uses Knauf and CertainTeed products for injection and dense-pack work.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer and cold in winter, or you have a 1950s-1960s home with minimal wall insulation.
What it costs in Lewisville
Injection foam wall insulation in Lewisville runs $3,000-$7,000 for a typical 1,200-1,800 square foot home.
How we do it
We drill small holes through the exterior or interior, inject foam into each cavity, and patch the holes. The foam fills tight and air-seals as it cures.
Drill & Fill Wall Insulation
Signs you need it
You hear every car pass on I-35E or Main Street, or your rooms heat up fast when the AC is off.
What it costs in Lewisville
Drill-and-fill in Lewisville with blown-in fiberglass or cellulose typically costs $2,500-$6,500 for a average home.
How we do it
We drill from the exterior where possible, dense-pack the cavity with blown material, and plug and paint-match the holes.
What Wall Insulation Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Injection foam wall insulation | $3,000-$7,000 |
| Drill & fill wall insulation | $2,500-$6,500 |
| Interior wall soundproofing | $1,800-$4,500 |
| New construction wall insulation | $1,200-$3,000 |
Can you insulate the exterior walls of my older Lewisville home without tearing out drywall?
Yes. Both injection foam and drill-and-fill work from the exterior or through small interior holes. The process is low-dust, and most jobs finish in one day. Call (855) 657-3403 for a wall cavity assessment.
Does wall insulation help with Lewisville noise from I-35E?
It makes a real difference. Filling empty wall cavities reduces airborne sound transmission, especially in homes near I-35E, Main Street, or the railroad corridor. Dense-pack and foam both outperform empty cavities by a wide margin.
Attic Cleaning & Rodent Proofing in Lewisville
Attic cleaning and rodent proofing in Lewisville solves two linked problems: the rat and squirrel pressure that comes with mature trees and 1980s construction gaps, and the contaminated, compressed insulation those pests leave behind. Doing only one half of the job means repeat problems. Our Attic Cleaning & Rodent Proofing service removes the waste, sanitizes the space, seals entry points, and installs clean insulation.
Attic Cleanout
Signs you need it
You hear scratching in the ceiling at night, smell a musty odor in the hallway, or find droppings in the attic.
What it costs in Lewisville
An attic cleanout in Lewisville typically runs $800-$2,000, depending on attic size and contamination level.
How we do it
We remove all debris and contaminated insulation, vacuum the attic floor with HEPA filtration, and prep the space for new material.
Rodent Proofing & Exclusion
Signs you need it
You see gnawed wiring, greasy rub marks along the soffits, or find entry holes around pipe penetrations and vents.
What it costs in Lewisville
Rodent proofing and exclusion in Lewisville runs $1,000-$3,000, including sealing typical entry points and adding vent guards.
How we do it
We seal all accessible entry points with metal mesh, foam, and structural repairs, then set up monitoring to confirm the exclusion works.
What Attic Cleaning & Rodent Proofing Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Attic cleanout | $800-$2,000 |
| Attic sanitizing & decontamination | $600-$1,800 |
| Rodent proofing & exclusion | $1,000-$3,000 |
| Full attic restoration | $2,500-$6,000 |
Do I need rodent proofing before new insulation in Lewisville?
Yes, in any attic with signs of rodent activity. Insulating over a live entry point just gives pests fresh nesting material. We exclude first, clean second, then insulate. Call (855) 657-3403 for an inspection.
Will attic cleaning get rid of the smell in my Lewisville home?
In most cases yes. The odor comes from droppings, urine, and contaminated insulation. Removing the material and sanitizing the deck usually eliminates it within a day or two. Some sub-slab odors may require separate treatment, which we’ll flag.
Home Energy Audit in Lewisville
A home energy audit in Lewisville gives you the exact map of where your house loses energy: the leaky attic floor, the failing duct wrap, the uninsulated wall cavities near Old Town, or all three at once. It’s the single most useful first step before spending money on insulation retrofits, because it tells you which fixes will pay back fastest. Our Home Energy Audit uses blower door testing, thermal imaging, and duct leakage measurements to quantify the problems.
Blower Door Test
Signs you need it
Your energy bills are consistently higher than neighbors’ and you can feel drafts near baseboards, outlets, and recessed lights.
What it costs in Lewisville
A blower door test in Lewisville, typically as part of a full audit, runs $600-$1,200 for the complete assessment.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure the total air leakage rate. This gives a hard number for how leaky the home is.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach the thermostat setting, or you suspect missing insulation in walls but don’t want to cut holes.
What it costs in Lewisville
Thermal imaging as part of a Lewisville home energy audit is included in the $600-$1,200 audit price.
How we do it
We scan walls, ceilings, and floors with an infrared camera to spot missing insulation, air leaks, and thermal bridging without opening the walls.
What Home Energy Audit Costs in Lewisville
| Item | Typical range in Lewisville |
|---|---|
| Full home energy audit | $600-$1,200 |
| Blower door test only | $250-$450 |
| Duct leakage test | $300-$600 |
| Insulation inspection only | $150-$350 |
Does a home energy audit make sense for my 1980s Lewisville home?
Yes, strongly. A 1980s Lewisville home likely leaks air at two to three times the modern rate and carries compressed insulation well below current code. The audit pinpoints which fixes matter most, so you don’t spend money guessing. Call (855) 657-3403 to schedule yours.
Will an energy audit tell me if my ductwork is leaking in Lewisville?
Yes. We perform a duct leakage test that measures how much conditioned air escapes outside the envelope. In many east Lewisville homes, original 1980s duct wrap has failed and the leakage test shows exactly how much you’re losing.

FAQs About Insulation in Lewisville, TX
How quickly can you schedule a job in Lewisville?
We typically schedule Lewisville visits within a few days of your call. Let us know about any specific comfort issue so we can prioritize accordingly. If your timing is flexible we’re happy to work around it, and either way we’ll confirm the exact appointment window with you before the day of the visit.
Do I need a permit for insulation work in Lewisville?
Routine attic and crawl space insulation generally does not require a separate permit in Lewisville. Larger jobs involving structural or mechanical changes sometimes do, and we handle that paperwork as part of the project.
How does the written estimate process work?
We inspect the attic, crawl space, or walls in person, measure the existing insulation, and give you a specific price in writing before any work begins. That estimate spells out materials, labor, and any disposal costs, and the number does not change once the crew arrives unless you ask us to add more scope to the job.
What areas near Lewisville do you cover?
Along with Lewisville, we serve Houston, Spring, The Woodlands, Katy, Pearland, and Humble. Reach out with your address and we will confirm coverage. If you’re not sure whether your address falls inside that range, just tell us your city and zip when you call and we’ll confirm coverage right away.
What happens to the insulation you remove?
Old insulation is bagged and hauled off-site as part of the job. Contaminated or pest-affected material gets extra containment before it leaves the home. We keep the work area clean throughout the job and walk you through the finished space before we leave.

What Lewisville Customers Say
"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."
- Grace Nakamura"Solid work on the spray foam in the rim joists and the garage ceiling. Scheduling slipped a day because of rain, which they called about ahead of time. Would use them again."
- Tom Reinholt
