Insulation in Plano, TX
Most Plano insulation jobs come down to one thing: homes built between 1978 and 1998 that are now fighting summer attic temperatures of 140°F or higher with settled, code-minimum fiberglass. Crawl space encapsulation is the exception here, not the rule, because the vast majority of Plano homes sit on slab-on-grade foundations. That means our work in Plano focuses heavily on attics, walls, and garage-adjacent spaces where the February 2021 freeze exposed exactly how much conditioned air was escaping. Call (855) 657-3403 and you’ll reach a live person who can talk through what your specific home needs, not a voicemail.
Why Plano Homes Are Different
Plano experienced one of the most concentrated suburban building booms in the country during the 1980s and early 1990s. East and central Plano neighborhoods filled in fast with single-story and two-story brick veneer tract homes built to the lax insulation standards of that era. Most attics were spec’d at R-19 to R-22, but decades of settling and HVAC dust have compacted original blown-in fiberglass down to 4 or 5 inches in many cases. We routinely measure actual R-values of R-11 to R-13 in attics nominally rated R-22.
Plano sits in IECC Climate Zone 3, which creates a specific problem: attic temperatures regularly exceed 140°F to 155°F in July and August. That makes radiant barriers and air sealing just as important as adding R-value. Then the periodic hard freezes that sweep through North Texas, most painfully in February 2021, expose how quickly under-insulated walls and unconditioned garage-adjacent spaces lose heat and put pipes at risk. Homes east of US-75, built out rapidly in the mid-1980s, show this gap between builder spec and actual performance more than almost anywhere else in Collin County.
Our Main Plano Services
Two services drive most of the calls we get from Plano homeowners: attic insulation overhauls for aging tract homes, and air sealing to stop the stack effect that pulls hot attic air into living spaces all summer. Here’s what each looks like in Plano.
Attic Insulation in Plano
Attic insulation in Plano is the single highest-impact upgrade for most homes built between 1978 and 1998. Original fiberglass has settled, HVAC dust has compacted it further, and the result is an attic performing far below its builder spec. We remove or top up old material, seal the attic floor, and blow in fresh insulation to a verified depth. The February 2021 freeze taught thousands of Plano homeowners exactly how much their attics were leaking, and the fix starts here. Attic Insulation in Plano covers what a full overhaul for your home involves.

Crawl Space Encapsulation & Vapor Barrier in Plano
Crawl space encapsulation in Plano is uncommon compared to older North Texas markets, because most Plano homes sit on slab-on-grade foundations. But the homes that do have crawl spaces, mostly custom builds and a handful of older properties, face the same North Texas humidity that can push ground moisture into floor framing and ductwork. Encapsulation seals that moisture out with a Crawl Space Encapsulation & Vapor Barrier system that keeps the area dry and the air above it cleaner. We approach each Plano crawl space as its own small climate, not a one-size-fits-all liner job.
Crawl Space Vapor Barrier
Signs you need it
You notice a persistent musty smell in rooms above the crawl space, or you see condensation on ductwork and floor joists when you look through the access door.
What it costs in Plano
A crawl space vapor barrier in Plano typically runs $1,200 to $3,000 depending on square footage and access.
How we do it
We lay a reinforced polyethylene liner across the crawl space floor, run it up the foundation walls, and secure it with mechanical fasteners so ground moisture can’t wick into framing.
Crawl Space Encapsulation
Signs you need it
Your floors feel damp or cold in winter even with the heat running, or you’ve spotted mold or efflorescence on foundation walls and piers.
What it costs in Plano
Full crawl space encapsulation in Plano typically runs $5,000 to $12,000 for a complete sealed system.
How we do it
We seal the floor and walls, close off vents, install a dehumidifier sized for the space, and add an optional sump pump if standing water appears after heavy rain.
What Crawl Space Encapsulation & Vapor Barrier Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Crawl space vapor barrier | $1,200 - $3,000 |
| Crawl space encapsulation | $5,000 - $12,000 |
| Crawl space dehumidifier | $1,800 - $3,500 |
| Crawl space sump pump | $1,500 - $3,000 |
Do I really need a dehumidifier in my Plano crawl space?
Most of the time, yes. North Texas humidity stays high from May through October, and a sealed crawl space without one can still collect damp air. A dehumidifier keeps humidity low enough to protect joists and ductwork year-round.
Is crawl space encapsulation worth it on a slab-on-grade home?
Plano’s dominant housing stock is slab-on-grade, so most homes here don’t have a crawl space at all. If your home does have one, encapsulation usually pays for itself through lower humidity and cleaner air. Call us for a straight answer on whether it makes sense for your specific house.
Spray Foam Insulation in Plano
Spray foam insulation in Plano addresses a problem slab-on-grade tract homes share: unconditioned garages and rim joist areas leak heated and cooled air straight into the attic. The February 2021 freeze put this on display, when pipes running through garage-adjacent walls froze across Collin County. Closed-cell and open-cell Spray Foam Insulation seals air movement far better than fiberglass batts alone, which is why we specify it for rim joists, garage ceilings, and attic roof decks where other insulation underperforms.
Closed-Cell Spray Foam
Signs you need it
Rooms over the garage stay cold in winter or hot in summer no matter how much you adjust the thermostat, and you can feel drafts near the rim joist from inside the home.
What it costs in Plano
Closed-cell spray foam in Plano typically runs $2.00 to $3.50 per board foot installed.
How we do it
We prepare the cavity, spray the foam to the specified depth, and trim it flush after curing so drywall or finish materials fit cleanly.
Rim Joist Spray Foam
Signs you need it
You feel cold air near where exterior walls meet the floor, or you’ve seen insect activity around the sill plate area inside a garage or basement-adjacent space.
What it costs in Plano
Rim joist spray foam in Plano typically runs $1,000 to $2,500 for an average home’s perimeter.
How we do it
We seal each rim joist cavity with closed-cell foam from the sill plate to the subfloor, cutting air infiltration and creating a moisture barrier in one pass.
What Spray Foam Insulation Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Closed-cell spray foam | $2.00 - $3.50 / board ft |
| Rim joist spray foam | $1,000 - $2,500 |
| Garage ceiling spray foam | $1,800 - $4,000 |
| Spray foam roof deck | $4,000 - $9,000 |
Should I spray foam my Plano attic roof deck or just the attic floor?
For most Plano tract homes, the attic floor is the better first move. Roof deck foam makes sense when you’re finishing the attic or your HVAC equipment and ductwork sit in an unconditioned attic. We’ll tell you which approach actually helps your house.
Does spray foam help with the Plano summer heat?
Yes, because it seals air leaks as well as insulates. In July and August, when attic temperatures hit 140°F or more, the air barrier matters as much as the R-value. Call (855) 657-3403 and we’ll walk you through what your home needs.
Blown-In Insulation in Plano
Blown-in insulation in Plano is the workhorse fix for the city’s aging tract housing stock. Most attics in homes built between 1978 and 1998 were spec’d at R-19 to R-22, but compaction and settling have left many measuring R-11 to R-13 in practice. Blown-In Insulation lets us add material quickly and evenly over an entire attic floor, restoring or exceeding the original spec without tearing out drywall. It’s the fastest path from a hot, drafty house to one that holds its temperature.
Blown-In Cellulose
Signs you need it
Your upstairs rooms stay hot in summer even with the AC running, or you can see bare spots and thin coverage when you look across your attic floor.
What it costs in Plano
Blown-in cellulose in Plano typically runs $1.50 to $3.00 per square foot installed.
How we do it
We load GreenFiber or a comparable cellulose product into our blower and apply it at the density required to hit your target R-value, checking depth with marked guides as we go.
Blown-In Top-Up
Signs you need it
Your existing insulation is clean and dry but only 4 to 5 inches deep, far below what Plano’s climate zone calls for.
What it costs in Plano
A blown-in top-up in Plano typically runs $800 to $1,800 for an average single-story home.
How we do it
We blow fresh fiberglass or cellulose over the settled material to reach a verified depth, which usually means R-38 to R-49 in a Plano attic.
What Blown-In Insulation Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Blown-in cellulose | $1.50 - $3.00 / sq ft |
| Blown-in fiberglass | $1.25 - $2.75 / sq ft |
| Dense-pack wall insulation | $2.50 - $5.00 / sq ft |
| Blown-in top-up | $800 - $1,800 |
How much blown-in insulation does a Plano attic actually need?
We target R-38 to R-49 for Plano attics, which usually means 12 to 16 inches of blown fiberglass or cellulose. Most homes built in the 1980s and 1990s are sitting at R-11 to R-13, so the gap is substantial.
Can you blow insulation into my walls without tearing out drywall?
Yes, dense-pack wall insulation goes through small holes drilled in the wall sheathing or drywall, then the holes are patched. It’s a clean way to upgrade walls in a Plano home that was never insulated properly. Call (855) 657-3403 for an exact quote.
Radiant Barrier Installation in Plano
Radiant barrier installation in Plano targets the single biggest thermal load on a North Texas home: the sun beating on an attic roof deck from June through September. When attic temperatures climb past 140°F, insulation alone can only slow heat transfer. Radiant Barrier Installation adds a reflective foil layer that bounces radiant heat back toward the roof instead of letting it radiate into your insulation and living space. In Climate Zone 3, this matters more than in most of the country.
Attic Radiant Barrier
Signs you need it
Your AC runs constantly in July and August, or your attic feels like an oven the moment you open the access hatch.
What it costs in Plano
An attic radiant barrier in Plano typically runs $1.50 to $3.00 per square foot installed.
How we do it
We staple or laminate reflective foil to the underside of your rafters, keeping an air gap that allows the foil surface to do the actual reflecting.
Radiant Barrier & Ventilation
Signs you need it
You’ve added insulation but your upstairs still won’t hold temperature, or you’ve noticed heat building up near the peak of the attic on hot afternoons.
What it costs in Plano
Radiant barrier paired with ventilation improvements in Plano typically runs $3,000 to $7,000.
How we do it
We install the radiant barrier and then verify your soffit and ridge vent airflow so the reflected heat actually exits the attic instead of building up.
What Radiant Barrier Installation Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Attic radiant barrier | $1.50 - $3.00 / sq ft |
| Radiant barrier foil | $1.00 - $2.00 / sq ft |
| Radiant barrier roof deck | $2.00 - $4.00 / sq ft |
| Radiant barrier & ventilation | $3,000 - $7,000 |
Does a radiant barrier really make a difference in a Plano summer?
Yes, when installed correctly with an air gap. It reduces the radiant heat load on your attic insulation, which keeps your ductwork and the air inside them cooler. The effect is most noticeable in July and August when roof deck temperatures peak.
Should I get a radiant barrier or more insulation first?
Start with insulation and air sealing. In Plano, most tract homes are severely under-insulated, so adding R-value delivers the biggest immediate gain. A radiant barrier then reduces the remaining radiant load. Call (855) 657-3403 and we’ll inspect what’s actually up there before recommending either.
Insulation Removal & Replacement in Plano
Insulation removal and replacement in Plano is a recurring job in the city’s older tract neighborhoods, especially east of US-75 where homes went up fast in the mid-1980s. Decades of roof leaks, rodent activity, and HVAC dust have contaminated or compacted much of the original blown-in fiberglass. Insulation Removal & Replacement lets us clear out that compromised material and install fresh insulation at current code levels, rather than simply burying the problem under a new top-up.
Attic Insulation Removal
Signs you need it
Your existing insulation is matted, compressed, or visibly dirty, or you’ve had a roof leak that soaked areas of the attic floor.
What it costs in Plano
Attic insulation removal in Plano typically runs $1.00 to $2.50 per square foot.
How we do it
We vacuum out the old material with a high-powered removal system, bag it, and haul it away, leaving the attic floor clean and ready for new insulation.
Contaminated Insulation Removal
Signs you need it
You’ve had rodents in the attic, or you can smell something persistent even after the animals are gone.
What it costs in Plano
Contaminated insulation removal in Plano typically runs $1.50 to $3.00 per square foot, plus sanitizing.
How we do it
We remove all affected material, sanitize the exposed surfaces, and seal entry points before installing new insulation so the problem doesn’t return.
What Insulation Removal & Replacement Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Attic insulation removal | $1.00 - $2.50 / sq ft |
| Contaminated insulation removal | $1.50 - $3.00 / sq ft |
| Vermiculite & old insulation removal | $2.00 - $4.00 / sq ft |
| Insulation replacement | $2.00 - $4.50 / sq ft |
Is it cheaper to just blow new insulation over the old stuff?
Sometimes, if the old material is dry, pest-free, and not too compacted. But if it’s contaminated or has settled to 4-5 inches of dust-laden fiberglass, removal and replacement gives you a clean, correct result. We’ll tell you which path makes sense for your Plano attic.
How do I know if my insulation needs to be removed?
Look for matting, odd smells, or rodent droppings. If you’re not comfortable going up, we’ll inspect it for you. Call (855) 657-3403 and a live person will schedule a look at your attic.
Attic Air Sealing in Plano
Attic air sealing in Plano addresses the stack effect that pulls conditioned air out of your home through every penetration in the attic floor. In summer, hot attic air gets dragged down through the same gaps; in winter, heated air escapes upward. Attic Air Sealing closes those paths with foam, caulk, and metal flashing, which makes every dollar you spend on insulation work harder. Given how much heat builds up in a Plano attic, sealing is usually the first thing we do before adding or replacing insulation.
Attic Floor Air Sealing
Signs you need it
You can feel drafts near interior walls or around light fixtures, or your home gets dusty faster than it should.
What it costs in Plano
Attic floor air sealing in Plano typically runs $800 to $2,000 depending on the number of penetrations.
How we do it
We seal every plumbing vent, electrical penetration, and drywall joint where the attic floor meets the living space below.
Can Light & Duct Boot Sealing
Signs you need it
You have recessed lights in upstairs ceilings, or you feel warm air around ceiling registers in summer.
What it costs in Plano
Can light and duct boot sealing in Plano typically runs $50 to $150 per fixture or boot.
How we do it
We seal around each recessed can with an approved cover or fire-rated enclosure, and seal duct boots where they meet the drywall.
What Attic Air Sealing Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Attic floor air sealing | $800 - $2,000 |
| Top plate & penetration sealing | $400 - $1,200 |
| Can light & duct boot sealing | $50 - $150 each |
| Attic hatch sealing | $100 - $300 |
How much difference does air sealing actually make in Plano?
In a typical 1980s Plano tract home, we often cut air leakage by 20 to 30 percent. That translates directly to lower cooling bills in summer and fewer cold spots in winter. Combined with insulation, it’s the highest-value upgrade most homes here can get.
Do I need to air seal before adding insulation?
Yes, always. Blowing insulation over unsealed penetrations just hides the leaks. Sealing first means the new insulation does its job. Call (855) 657-3403 and we’ll explain what your attic needs in plain terms.
Wall Insulation in Plano
Wall insulation in Plano is a common upgrade for the city’s brick veneer tract homes, many of which have only fiberglass batts that sagged or were never installed to begin with. In winter, especially during the hard freezes that cycle through North Texas, uninsulated walls pull heat out fast. Wall Insulation fixes that with injection foam or dense-pack methods that fill wall cavities without gutting the house. For Plano’s slab-on-grade construction, walls are a bigger factor in comfort than many homeowners realize.
Injection Foam Wall Insulation
Signs you need it
You have rooms that stay cold in winter even with the heat on, or you’ve noticed cold exterior walls in a specific bedroom or bathroom.
What it costs in Plano
Injection foam wall insulation in Plano typically runs $2.50 to $5.00 per square foot of wall area.
How we do it
We drill small holes in the wall, inject slow-rise foam that expands into the cavity, then patch the holes. The process works on brick veneer and framed walls alike.
Drill & Fill Wall Insulation
Signs you need it
Your home was built between 1978 and 1998 and you suspect the wall cavities have little or no insulation.
What it costs in Plano
Drill and fill wall insulation in Plano typically runs $2.00 to $4.00 per square foot of wall area.
How we do it
We blow dense-packed cellulose or fiberglass into wall cavities through small access holes, checking density as we go so the fill stays put and performs.
What Wall Insulation Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Injection foam wall insulation | $2.50 - $5.00 / sq ft |
| Drill & fill wall insulation | $2.00 - $4.00 / sq ft |
| Exterior wall insulation | $3.00 - $6.00 / sq ft |
| Interior wall soundproofing | $1.50 - $3.50 / sq ft |
Can you insulate my walls without removing the brick?
Yes. We work from the inside or drill through the mortar joints, fill the cavity, and patch cleanly. For Plano brick veneer homes, this is the standard approach. Call (855) 657-3403 for an inspection and a straight answer on your walls.
Why are my exterior walls cold even though I have attic insulation?
Attic insulation doesn’t stop heat loss through wall cavities. Many Plano tract homes have uninsulated or poorly insulated walls, which shows up as cold spots in winter. Wall insulation fixes that directly.
Attic Cleaning & Rodent Proofing in Plano
Attic cleaning and rodent proofing in Plano is a service that older brick veneer homes need more than most people realize. Squirrels, rats, and mice find their way into attics through roof gaps and soffit vents, then nest in the settled fiberglass insulation that so many Plano homes still have up there. Attic Cleaning & Rodent Proofing removes that contaminated material, sanitizes the space, and seals every entry point so the animals can’t return. The February 2021 freeze pushed rodents indoors in large numbers, and many of those attics still show the damage.
Attic Cleanout
Signs you need it
You hear scratching overhead at night, or you’ve spotted droppings and nesting material when you look into the attic.
What it costs in Plano
An attic cleanout in Plano typically runs $500 to $1,500 depending on attic size and contamination level.
How we do it
We remove all contaminated insulation and debris, vacuum the space clean, and prepare the attic for sanitizing and new insulation.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents in the attic before and want to make sure they can’t get back in.
What it costs in Plano
Rodent proofing and exclusion in Plano typically runs $800 to $2,500 for a typical single-story home.
How we do it
We seal every gap, vent, and roof joint with rodent-resistant materials, then verify the attic is secure before any new insulation goes in.
What Attic Cleaning & Rodent Proofing Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Attic cleanout | $500 - $1,500 |
| Attic sanitizing & decontamination | $300 - $1,000 |
| Rodent proofing & exclusion | $800 - $2,500 |
| Attic restoration | $1,500 - $4,000 |
Should I replace my insulation after rodents have been in the attic?
Usually yes. Rodent droppings and urine contaminate the insulation and leave odors that linger. We remove the affected material, sanitize, and install fresh insulation so the attic is clean and safe.
How fast can you get rodents out of a Plano attic?
Most exclusion and cleanout jobs are done in one or two visits. The entry points get sealed during the first visit, and most Plano jobs are completed in a single visit overall. Call (855) 657-3403 and a live person will get you scheduled.
Home Energy Audit in Plano
A home energy audit in Plano is the diagnostic starting point that makes every other insulation service smarter. Instead of guessing which part of your home is losing the most conditioned air, we measure it. Home Energy Audit uses a blower door test, thermal imaging, and duct leakage testing to pinpoint exactly where your home is failing. For a 1980s or 1990s Plano tract home, that usually means the attic floor, duct boots, and exterior walls, but the data tells us where to focus first.
Blower Door Test
Signs you need it
Your heating and cooling bills feel too high for the square footage, or you feel drafts in rooms even with windows closed.
What it costs in Plano
A blower door test in Plano typically runs $200 to $500 as part of a full energy audit.
How we do it
We mount a calibrated fan in an exterior door frame, depressurize the house, and measure how much air leaks through every crack and penetration.
Thermal Imaging Inspection
Signs you need it
You have rooms that stay noticeably hotter or colder than the rest of the house and you want to see exactly where the problem is.
What it costs in Plano
A thermal imaging inspection in Plano typically runs $150 to $400 as part of a full energy audit.
How we do it
We scan walls and ceilings with an infrared camera to find missing insulation, air leaks, and thermal bridging that a visual inspection would miss.
What Home Energy Audit Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Blower door test | $200 - $500 |
| Thermal imaging inspection | $150 - $400 |
| Insulation inspection | $100 - $300 |
| Duct leakage test | $200 - $500 |
Is a home energy audit worth it before I insulate?
Yes, especially in Plano where homes of the same era can have very different problems. The audit tells us whether your money is better spent on air sealing, wall insulation, or attic work. It prevents spending on the wrong fix.
How long does a home energy audit take in Plano?
Most audits take two to three hours for a typical single-story Plano home. You get a clear report showing where the air is leaving and what to fix first. Call (855) 657-3403 and a live person will get yours scheduled.

What Plano Customers Say
"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"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
- Priya Raman
