Wylie's 1990s and 2000s homes near Lake Lavon sit on slab-on-grade foundations with vaulted ceilings, bonus rooms over attached garages, and attics that hit 140 degrees by mid-afternoon every summer. When your AC runs all day and your upstairs never cools down, or when condensation drips off metal building rafters in winter, spray foam insulation and air sealing are the tools that actually work.
Mckinney Spray Foam Insulation has been serving Wylie (75098) and the surrounding McKinney area since 2012. We know the building stock here, the moisture challenges that come with Collin County's black clay and seasonal swings, and how to spec the right foam type and thickness for your home or commercial space. We show up with fully insured crews, write estimates with R-value and thickness specs, and we stay reachable when the work is done.
Spray Foam Insulation in Wylie (75098)
Wylie's homes carry real insulation challenges. The 1990s and 2000s two-story brick homes with vaulted ceilings and bonus rooms over three-car garages have attics with low slope and high heat load. Your AC handler and ductwork sit in an unconditioned attic that bakes all afternoon, and air leaks around rim joists, band joists, and poorly sealed duct runs let conditioned air escape into the heat. Summer electricity bills climb fast. In winter, moisture from indoor humidity condenses on cold metal and wood, and compressed or damp insulation stops working and starts to rot.
Closed cell spray foam seals those air leaks completely, raises the R-value of your attic or crawl space, and stops condensation before it starts. Open cell foam works well in sealed roof decks and interior walls where vapor permeability is an advantage. Wall injection foam retrofits closed cavities in existing homes without tearing into drywall. If old insulation is wet, compressed, or fouled, we remove it and haul it away before we spray anything new. Our fully insured crews have been doing this work in Wylie and McKinney for over a decade.

How a Job Works in Wylie
First, we visit your home or building for a free on-site assessment. We look at what you have now, measure the spaces that need insulation, ask about your comfort problems and energy bills, and explain what open cell and closed cell foam can do for you. We answer questions honestly, including when blown-in insulation is the right answer instead. Then we write a detailed estimate with R-value and thickness specs so you know exactly what you are paying for.
When you say go, our crew schedules the work around your life. We set up mechanical ventilation to move air during the spray and cure process. If insulation has to come out first, we remove it, bag it, and haul it away. We spray the foam to the thickness and density specified in the estimate, working in sections so the material cures properly. We seal rim joists, band joists, attic bypasses, and the gaps around ductwork that bleed your conditioned air into the unconditioned space. If you are home, we give you a re-entry window of twenty-four to forty-eight hours before the space is safe to occupy again.
When we are done, we clean up, walk through the job with you, and make sure you understand how to maintain what we installed. You get our direct phone number and you can reach us if you have questions later.
Spray foam insulation in Wylie runs from roughly $0.55 per board foot for open cell foam to $1.20 per board foot for closed cell, depending on the density and thickness you need. Attic foam typically starts around $1.50 per square foot. Wall injection foam runs about $2 per square foot. A crawl space spray foam job usually starts at $2,500.

Metal buildings and barndominiums run roughly $1.75 per square foot. The final cost depends on the area to cover, the R-value and thickness you need, whether you are using open or closed cell foam, what existing insulation has to come out, and how easy our crew can access the space.
