Palmhurst's newer homes sit on concrete slabs with big attics overhead, three-car garages, and bonus rooms that catch the brutal Rio Grande Valley sun. When your air handler and ductwork run 150 to 160 degrees Fahrenheit for half the year under some of the hottest sun in Texas, attic temperature and cooling costs become a real problem, and the humidity that pushes inland from the Gulf makes condensation on cold surfaces a year-round risk.
McAllen Spray Foam Insulation has served Palmhurst (78573) and the surrounding areas since 2012. We know the newer construction in north McAllen and the two-story brick and stucco ranches with open floor plans and cathedral ceilings that need the right insulation strategy. When homeowners in Palmhurst call, they're usually facing a summer electricity bill that has gotten out of hand, a bonus room that never cools down, or damp insulation that has to come out before anything new goes in.
Spray Foam Insulation in Palmhurst (78573)
Palmhurst's 1990s and newer construction carries vented attics with pitched roofs and plywood decking, concrete slab foundations, and cavity walls that were often left uninsulated or filled with fiberglass batts that settle and shift. Your attic sits directly under a metal roof or asphalt shingles that absorb heat all day, and the ductwork routed through that space has to fight to stay cool. In summer, attic temperatures climb past 150 degrees, and the humidity that rolls in from the Gulf during the hot season and the rare hard freezes in winter both drive moisture into the walls and attic cavities. Closed cell spray foam seals air leaks and creates a vapor barrier, stopping that moisture before it condenses on your ductwork or wood framing.
Palmhurst homes also feature bonus rooms built over the garage, and those spaces are notoriously hard to cool because the garage below is often uninsulated and vented. Spray foam on the rim joist, the band joist, and the garage ceiling itself stops the heat transfer and the air leaks that make that room uncomfortable. We've been doing this work in Palmhurst and across the McAllen area for over a decade, and we know exactly where the problems hide in your house.

How a Job Works in Palmhurst
We start with a free on-site assessment. We walk your attic, crawl space, or garage, measure the area to be covered, look at what's already there, and check for moisture, damage, or insulation that has to be removed first. We'll explain what R-value and thickness you need for your specific space, whether open cell or closed cell makes sense for your situation, and what the work will cost. You get a written estimate with R-value and thickness specifications so you know exactly what you're paying for.
On the day of the job, our fully insured crew sets up mechanical ventilation to control fumes during the spray and cure. We apply the foam in controlled passes to the thickness specified in your estimate, using the correct material ratio and drum temperature. If you're living in the house, we establish a re-entry window of twenty-four to forty-eight hours, depending on the foam type and the space being sprayed. If your attic has old, compressed, or rodent-fouled insulation, we remove it first and haul it away. If you have a failed spray job from another crew that never cured and still smells, we'll tell you what went wrong and what it takes to fix it.
We clean up thoroughly and walk through the finished work with you. Your property gets left clean, and you have a contact number if questions come up after we're done.
Attic spray foam in Palmhurst typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on the area, the R-value you need, and what has to be removed first. A bonus room over the garage with rim joist and band joist sealing might run $650 to $1,500. If you have a crawl space, budget from $2,500 up, depending on access and square footage. Insulation removal alone starts at $950. The biggest cost factors are the total area to be sprayed, the R-value and thickness you need (which depends on your code and your climate zone), whether you choose open or closed cell, and whether old insulation has to come out first. Call us at (956) 540-5716 for a free estimate. We'll measure your space, explain what you need, and give you a firm price in writing.
