Aransas Pass sits on the water, and that salt air, Gulf humidity, and storm-season wind shape every house in town. Your home is likely a frame or brick ranch built in the 1950s through 1980s, sitting on a concrete slab with a vented attic carrying your air handler and ductwork that runs hot and humid year-round.
When that attic temperature climbs to 150 degrees and your electric bill follows, or when condensation starts dripping off the underside of your metal boat barn or garage, you need spray foam insulation and air sealing done right by someone local. Corpus Christi Spray Foam Insulation has been serving Aransas Pass (78336) and the surrounding area since 2012. We know your building stock, your coastal weather, and what fails when it is not done well.
Spray Foam Insulation in Aransas Pass (78336)
Aransas Pass homes face a specific insulation challenge: your attics are vented, your ductwork runs through them, and the Gulf humidity pushes moisture vapor inward all year. In summer, that attic sits at 140 to 160 degrees Fahrenheit. In hurricane season and winter cold snaps, the temperature swings and the humidity swings with it. Old frame homes and pier-and-beam foundations have rim joists and band joists that leak conditioned air and let moisture in. Newer brick ranches and two-stories have closed stud cavities with little to no insulation, hot west walls that never cool down, and bonus rooms over garages that are impossible to condition. Metal buildings and boat barns sweat on the inside when warm, humid air meets a cold metal roof or wall.
Spray foam insulation seals the air leaks and controls the moisture at the source. Closed cell foam stops the vapor and adds structural strength. Open cell foam breathes and is gentler on older framing. We remove and replace compressed, damp, or rodent-fouled insulation before we spray anything new. We have been doing this work in Aransas Pass and the Corpus Christi area for over a decade. We know what works here.

How a Job Works in Aransas Pass
We start with a free on-site assessment. You call us at (361) 278-8446 or contact us online, and we visit your home to see what needs to be done. We look at your attic access, your ductwork, any existing insulation, and the spaces that need to be sealed. We answer your questions and give you a written estimate with R-value and thickness specifications, so you know exactly what you are paying for.
On the day of the work, our crew arrives with all equipment and materials. If insulation has to come out first (damp, compressed, or rodent-fouled), we remove it and haul it away. We set up mechanical ventilation to manage the spray and cure process safely. We spray the foam to the thickness and coverage specified in your estimate. We let it cure with the ventilation running. Depending on the scope and the weather, that is typically twenty-four to forty-eight hours before you can re-enter the space normally.
When the work is done, we clean up the site, do a final walkthrough with you, and answer any questions. Your home is clean and ready to go.
Attic spray foam in Aransas Pass typically runs from $1.50 per square foot for open cell foam to $1.20 per board foot for closed cell, depending on the thickness and R-value your code and your comfort require. A typical 1,200 square foot attic with open cell foam to R-38 might run $1,800 to $2,400. Wall injection foam for a closed cavity runs from $2 per square foot. Crawl space foam starts at $2,500 and goes up with the area and the moisture work required. Rim and band joist sealing starts at $650. If you have old, wet, or rodent-fouled insulation that has to come out first, removal runs from $950 and up depending on the area and the condition. The final cost depends on the square footage or board footage to cover, the R-value and thickness you need, whether you choose open or closed cell, and what has to be removed before we spray. Call us at (361) 278-8446 for a free estimate. We will walk the property with you, explain what applies to your home, and give you a firm price in writing.
