Fast, Reliable Attic Insulation Across Plano
Most Plano homes built between 1978 and 1998 still carry builder-grade R-19 or R-22 attic batts, now compressed, settled, and far below Texas’s current R-38 requirement. We’re Topside Attic Insulation, and we fix that gap daily across Plano, from Spring Creek corridor ranches to two-story brick-veneer homes in the K-Area. Attic insulation replacement or a blown-in top-up on a typical Plano house runs $2,400-$6,800, and we publish the before-and-after blower-door numbers so you see exactly what changed. Call (218) 261-7714 and we’ll give you a written price before any work starts.
Why Topside Attic Insulation Is Plano’s Preferred Attic Insulation Company
Plano homeowners tend to research before they call, and they ask the right questions: What was the blower-door reading before and after? Where exactly did you air seal? What did the old batts measure when you pulled them out? We answer with documentation, not adjectives. That’s why a disproportionate share of our Dallas-Fort Worth attic work lands in Plano zip codes like 75023, 75025, and 75074. It’s not because we advertise harder. It’s because we hand the customer a written scope, a photo record, and two blower-door numbers they can compare side by side.
Since 2016, every Attic Insulation job we’ve completed has operated under The Haven Standard: a written price before work starts, air sealing completed before any insulation is added, and a documented record when the crew leaves. That last part matters in Plano specifically. The homes here are uniformly slab-on-grade, brick-veneer, high-volume builder construction. The failure patterns are predictable, which means a documented, repeatable process catches what a “blow and go” crew misses.
Wes Okafor, who leads our crews, puts it plainly: if a contractor won’t show you the blower-door reading, they’re selling you fluff. We will.
Our Attic Insulation Services in Plano
Blown-In Attic Insulation
Blown-in fiberglass, usually Owens Corning AttiCat or Johns Manville Climate Pro, is our most common spec for Plano’s large attic planes. These systems let us build to R-38 or R-49 with even coverage, including the gaps and voids that plague 1980s Centex and Ryan builds. We run it after air sealing, never before. That order is non-negotiable under Haven Standard, and it’s the single biggest reason our blower-door numbers post bigger drops than insulation-only contractors.
Attic Batt Insulation
Batt insulation has its place in Plano, particularly for cathedral ceiling pockets, knee walls, and areas where blown material would drift. We stock Rockwool and Knauf batts for jobs where compression resistance and moisture tolerance matter. In a Plano summer, the difference between a properly fitted batt and a compressed builder batt from 1987 is as much as 20°F at the ceiling plane. We document that with photos before and after.
Attic Insulation Top-Up
If your existing batts are intact but thin, a top-up is the most cost-effective path to R-38. In Plano we price a top-up on a 2,000-2,800 sq ft home between $1,800 and $3,400. The caveat: top-ups without air sealing are exactly what we won’t do. Blowing new fiberglass over an unsealed attic floor is like patching a boat without stopping the leak. We seal top plates, can lights, plumbing penetrations, and the pull-down stair first, then we blow.
Attic Insulation Replacement
Plano’s 30-45-year-old batts are frequently beyond saving. The fiberglass has compressed to R-9 or R-11 in the worst cases, and the kraft paper facing is often deteriorating. Replacement in Plano runs $2,800-$6,500 depending on square footage and whether removal is straightforward. We vacuum out the old material, document what it measured, seal everything, and install new insulation to current code. Every replacement job includes before-and-after blower-door readings.

Trusted Brands We Service in Plano
We install Owens Corning, Johns Manville, Knauf, and Rockwool insulation, and we match the material to the house rather than the other way around. No proprietary product lock-in. If a Plano homeowner wants Rockwool for superior sound damping between floors, that’s what we quote. If blown-in Owens Corning fiberglass makes more sense for a sprawling single-story off Coit Road, we spec that. We keep material lead times short, and most Plano jobs are scheduled within 7-10 days of the written estimate.
Common Attic Insulation Problems We See in Plano Homes
- No air sealing at the top plate. Plano’s 1980s production builders stapled batts and moved on. The seam where the drywall meets the wall top plate is wide open in most of these houses, letting 150°F attic air pour down through wall cavities.
- Compressed R-19/R-22 batts that have collapsed to R-9 or worse. Fiberglass batts lose loft over decades, especially under Plano’s sustained heat. A batt installed at R-19 in 1987 is more likely R-9 today, and nobody has ever pulled it back up to check.
- Uninsulated pull-down attic stairs. In east Plano’s Spring Creek and K-Area subdivisions, the pull-down stair was installed raw from the factory: no insulation, no weatherstripping, no air seal. One uninsulated stair can leak as much heat as a significant portion of the surrounding attic floor combined.
- Inadequate soffit baffles and blocked ventilation. Production builders in Plano rarely installed baffles correctly, if at all. We routinely find soffit vents blocked by blown debris or original batts shoved tight against the roof decking, which stifles airflow and drives attic temperatures even higher.
Attic Baffles & Ventilation Prep in Plano
The city’s hot, humid Zone 3A climate means attic ventilation is not a nice-to-have. In July, an under-ventilated Plano attic can hit 155°F, and that heat radiates down through the ceiling for hours after sundown. Before we add any insulation, we check every soffit, install baffles where they’re missing, and confirm the ridge or box vents are actually moving air. This prep is included in every attic insulation scope and documented in the photo record, so you know the ventilation path was verified, not assumed.
Pricing for Attic Insulation in Plano, TX
Here’s what we quote on Plano jobs, written plainly. An attic insulation top-up on a 1,800-2,500 sq ft brick-veneer home typically runs $1,800-$3,400. A full attic insulation replacement (removal, air sealing, new blown-in to R-38) on the same home runs $2,800-$6,800. Batt insulation for knee walls or limited areas lands between $900 and $2,400. Attic baffles and ventilation prep folds into the overall scope and usually adds $400-$900. Larger two-story homes west of Preston Road, with their bigger attic planes, skew toward the upper end. Every estimate is a fixed, written number. No hourly billing, no “it depends” when you actually call. Bring us a competing written estimate and we’ll sit down and read it with you, line by line. That’s the Free Second Opinion, and it’s always been part of how we work in Plano.

FAQs - Attic Insulation in Plano
Because the original R-19/R-22 fiberglass batts installed by builders like Centex, Ryan, and Kaufman & Broad have compressed and settled after 35-45 years of Plano heat, often dropping to R-9 or R-11. Once the material has collapsed, adding more insulation on top doesn’t restore the lost R-value. We assess the condition during the written estimate. Call (218) 261-7714 for a fixed quote.
The uninsulated pull-down attic stair. Builders in that era installed the stair raw and never sealed or insulated it, and it leaks conditioned air year-round. In Plano’s cooling-first climate, that single gap can account for a meaningful share of the home’s total heat gain. We seal and insulate it on every applicable job.
Cooling dominates. Plano sits in IECC Climate Zone 3A with sustained summer temperatures above 100°F, so the primary payoff from attic insulation is reducing cooling load. That said, the February 2021 Winter Storm Uri event proved these homes are undersized on the heating side too. An R-38 or R-49 attic improves both, but the annual energy savings in Plano skew heavily toward the cooling months.
Entirely at the attic plane. Plano’s dominant stock is slab-on-grade, so there’s no under-floor work to consider. We focus on air sealing the attic floor, insulating to R-38 or R-49, and verifying ventilation. The process is straightforward in these homes because the construction is so consistent across the city.
Yes. We measure what’s in the attic directly, check the depth and condition of existing batts, and run a blower-door test to quantify how much air the envelope is losing. No drywall removal needed. Call (218) 261-7714 for a free inspection and a written price before any work begins.
