The Colony's lakeside neighborhoods and 1970s-90s ranch homes near the water carry original attics that hit 140 degrees by mid-afternoon in summer, with west-facing brick walls that bake all day and AC units struggling to keep up. Your electric bill tells the story: hot attics with marginal insulation, closed walls with no cavity fill, and air leaks around rim joists and band boards that let conditioned air escape while hot outside air seeps in.
Mckinney Spray Foam Insulation has been serving The Colony and the McKinney area since 2012. We know your homes. We know what happens when an original attic with blown-in fiberglass starts to settle and compress, and we know why a bonus room over the garage or a back bedroom upstairs never cools down. We spray foam where it counts, seal the air leaks that matter, and leave your property clean.
Spray Foam Insulation in The Colony (75056)
The Colony's housing stock is a mix of 1970s-90s single-story brick ranches with low-slope attics and original fill insulation, plus newer two-story homes in Stonebridge Ranch and the subdivisions spreading toward Celina and Melissa. Almost every house has its air handler and ductwork routed through a vented attic. In summer, that attic climbs past 140 degrees. Your AC runs constantly, your duct seams leak conditioned air into unconditioned space, and your insulation either settles and compresses or never had enough R-value to begin with. West-facing walls bake all afternoon. Crawl spaces and rim joists under first-floor rooms pull in humid outside air and let it condense on cold mornings. Closed walls in older homes have zero cavity insulation. Metal buildings and barndominiums on acreage east toward Princeton and Blue Ridge sweat condensation on the underside of the roof deck in spring and fall.
We spray closed cell and open cell foam in attics, walls, crawl spaces, rim joists and garages. We remove and replace insulation that has failed or become damp. We seal air leaks around ductwork, band joists, and penetrations. We work in tight attics and crawl spaces. We coordinate around occupied homes and respect the twenty-four to forty-eight hour re-entry window after cure. We've been doing this work in The Colony and the McKinney area for over a decade.

How a Job Works in The Colony
You call us at (469) 247-0288 or request an estimate online. We schedule a free on-site assessment. We walk your attic, crawl space or wall cavity, measure the area to be sprayed, check what insulation is already there, and look for moisture, settling, compression or contamination that has to be addressed before any foam goes down. We explain what you need, why, and what it will cost. We give you a written estimate with R-value and thickness specifications so you know exactly what you're paying for.
On the day of the work, we set up mechanical ventilation in the space being sprayed so fumes can escape safely. We control the foam application: correct thickness per pass, the manufacturer ratio and drum temperature, so the foam cures properly and does not smell for weeks. If we're removing old insulation first, we do that and haul it away. If we're sealing air leaks around ductwork, rim joists or band boards, we do that before or after the spray, depending on the job. We respect your home: we protect floors and belongings, we keep the work area clean, and we leave your property as we found it.
After the foam has cured and mechanical ventilation is complete, we do a final walkthrough with you. We show you what we've sprayed, confirm the coverage and thickness, and answer any questions. Then we're done.
Spray foam pricing in The Colony depends on the area to cover, the R-value and thickness you need, whether you're choosing open cell or closed cell, what old insulation has to come out first, and how easy or difficult the space is to access. A typical attic top-up on a 1,500-square-foot ranch might run from $2,500 to $5,000 for open cell foam at 3.5 inches (R-12 per inch) or closed cell at 2 inches (R-7 per inch). A crawl space retrofit under a first-floor room might start at $2,500 and go higher if the space is damp or if old insulation has to be removed. Wall injection foam in a closed 1970s-90s wall cavity runs from $2 per square foot and up. Rim joist and band joist sealing on a 40-foot perimeter might start at $650. Insulation removal alone runs from $950 depending on volume and condition. Every job is different. The best way to know what yours will cost is to call us at (469) 247-0288 for a free estimate. We'll give you a number you can trust.
