Robstown sits in the heart of cotton country where old frame homes and metal farm buildings face the same enemy: Gulf humidity that creeps in year-round and summer heat that climbs into the attic and never lets go.
Most Robstown homes were built in the 1950s through 1970s on concrete slabs with vented attics carrying ductwork that runs 140 to 160 degrees Fahrenheit through nine months of the year. The walls are often solid brick or frame with no cavity insulation, and the crawl spaces under older homes collect moisture from the coastal prairie soil. When your air conditioning bill climbs and the back bedroom stays hot no matter what you do, it is almost always because the attic and the rim joists around your foundation are leaking conditioned air into the heat and humidity outside. Corpus Christi Spray Foam Insulation has been serving Robstown and the surrounding cotton and ranch country since 2012, and we know exactly what needs to come out and what needs to go in.
Spray Foam Insulation in Robstown (78380)
Robstown's older frame homes and the metal storage buildings scattered across the cotton farms around town face two problems that spray foam solves. First, the attics in these homes were built with ventilation gaps and settling insulation that never sealed the air leaks where the ductwork runs and where the walls meet the roof deck. Second, the walls themselves, especially on the west side of the house, have no insulation at all, or the insulation that was there has compressed over fifty years and no longer holds R-value. In summer, the combination of uninsulated walls and a leaky attic means your air conditioning is cooling the outdoors, not your home. In the humid season, moisture condenses on the underside of the roof deck and on metal ducts, and wet insulation loses its value and invites mold and mildew. The rim joists and band joists where the foundation meets the frame are almost always open to the crawl space, and they bleed conditioned air directly into the soil.
We have been installing closed cell and open cell spray foam in Robstown attics, walls, and crawl spaces for over a decade. Our crews are fully insured and experienced with the tight access in older frame homes and with the metal buildings that store equipment and cotton equipment across the region. We know which foam type is right for your space, what thickness the energy code requires at your address, and what has to come out before we spray anything new.

How a Job Works in Robstown
We start with a free on-site assessment. We walk your attic, crawl space, or walls, measure the area to be insulated, and look at what is already there. If insulation is wet, compressed, or fouled by rodents or pests, we tell you straight: that material has to come out first, and we can handle the removal. We give you a written estimate that specifies the R-value and thickness we will install, the foam type (open or closed cell), and the total cost. There are no surprises and no pressure.
On the day of the work, our crew sets up mechanical ventilation to manage the spray and odor during application. If you are home, we ask you to leave for the re-entry window, which is typically twenty-four to forty-eight hours. We protect your floors, fixtures, and belongings, and we work methodically to build the foam to the exact thickness specified in your estimate. In Robstown's older homes, access is often tight, and we take our time to get into the corners and around the ductwork where the air leaks happen. If you have an occupied crawl space or a tight attic with low headroom, we plan the work around your schedule.
When the foam has cured, we clean up all debris, remove our equipment, and do a final walkthrough with you to confirm the work is complete and your home is ready. We leave your property clean and ready to use.
Pricing for spray foam insulation in Robstown depends on what you are insulating and what has to be removed first. A typical attic foam job in a Robstown frame home, starting from $1.50 per square foot, covers anywhere from 1,200 to 2,500 square feet and runs between $2,500 and $4,500 before any removal. Wall injection foam for closed walls in a 1950s brick ranch, starting from $2 per square foot, typically costs $3,000 to $6,000 depending on the square footage of wall and the R-value required. A crawl space foam job, starting from $2,500, depends on the size of the space and whether the insulation is wet or needs to be removed first. Insulation removal, starting from $950, is often the biggest variable: if you have old blown-in fiberglass or cellulose that is matted down or contaminated, it has to come out before we spray foam. The best way to know your cost is to call us at (361) 278-8446 for a free estimate.
