Plano's 1970s and 1980s brick two-stories are hitting the age where original attic insulation has flattened and decades of hail have tested every roof. Your upstairs bedrooms stay hot all summer, your electricity bill climbs every June, and you suspect the insulation that was installed forty years ago is no longer doing the job.
Mckinney Spray Foam Insulation has been serving Plano and the McKinney area since 2012. We know the neighborhoods around Plano Parkway and the older subdivisions off Virginia Parkway, we understand the vented attics that hit 140 degrees by mid-afternoon, and we specialize in spray foam insulation and air sealing that actually fixes the problem. We're fully insured, we work year-round, and we show up with a written estimate that spells out exactly what you're getting in R-value and thickness.
Spray Foam Insulation in Plano (75074)
Plano's housing stock runs mostly 1970s and 1980s brick two-stories with vaulted ceilings, bonus rooms over attached garages, and west-facing walls that bake all afternoon. Almost every house routes its air handler and ductwork through a vented attic. In summer, that attic hits 140 degrees. The original fiberglass or cellulose insulation has compressed over decades, moisture from the cooled ductwork condenses in the attic air, and the upstairs stays hot no matter how hard the AC runs. Spring hail and the occasional winter ice storm test every roof. Many homes have closed walls with no cavity insulation, crawl spaces under additions, or rim joists and band joists that leak conditioned air straight outside.
Spray foam insulation solves all of it. We seal the attic, we inject foam into walls, we condition crawl spaces, we air-seal rim and band joists, and when the old insulation has to come out first because it's damp or compressed or fouled, we remove it and haul it away. We've been doing this work in Plano and the surrounding McKinney area for over a decade. We know the local building code, we coordinate with your city's building department, and we leave your property clean.

How a Job Works in Plano
We start with a free on-site visit. You walk us through the problem (hot upstairs bedrooms, a bonus room that never cools, condensation in the crawl space, or an electricity bill that has become unaffordable), we inspect the attic and the spaces to be sprayed, and we ask about any insulation that's already there. We measure the area, we check for moisture or damage that has to be fixed before foam goes in, and we explain what open cell and closed cell foam do and which one makes sense for your job.
We provide a written estimate with R-value and thickness spelled out. No surprises, no fine print. If we're removing old insulation first, we schedule that work separately so the space dries out before we spray. On the spray day, we set up mechanical ventilation, we apply the foam in controlled passes to the thickness and density the manufacturer specifies, and we verify the cure. In Plano, where most homes are occupied, we observe a twenty-four to forty-eight hour re-entry window before the space is fully usable. We clean up as we go, haul away all debris, and walk through the finished job with you.
Attic spray foam insulation in Plano typically runs from $1.50 per square foot for open cell foam on a straightforward attic, up to $2.00 per square foot or more if the space is tight, if old insulation has to come out first, or if you choose closed cell foam for higher R-value in a thin profile. Wall injection foam for closed walls starts around $2.00 per square foot. Crawl space work is usually priced by the job and runs from $2,500 and up, depending on the area and whether the crawl space needs moisture control first. Rim and band joist sealing starts at $650. Insulation removal runs from $950 depending on the volume and condition. The cost drivers are always the same: how much area we're covering, what R-value and thickness you need, whether old insulation has to come out, and how tight the access is.
