Port Aransas beach homes and canal properties sit raised on concrete pilings, built to weather the Gulf and facing salt air, tropical humidity, and wind that never really stops. Your attic, crawl space under the pilings, and the rim joists holding the house up are the places where moisture condenses, energy leaks, and salt-laden air corrodes anything exposed.
Since 2012, Corpus Christi Spray Foam Insulation has been the local choice for homeowners and property managers in Port Aransas (78373) and across the Corpus Christi area who need spray foam insulation that actually stays put and air sealing that holds up to the coast. We know your homes, your humidity, and what happens when the work is done wrong.
Spray Foam Insulation in Port Aransas (78373)
Port Aransas homes are built on a different foundation than inland Corpus Christi. Your beach and canal houses sit on concrete pilings, with crawl spaces underneath that face constant moisture from Gulf humidity and storm surge risk. The rim joists and band joists that tie the structure together are exposed to salt air and the spray from nor'easters. Attics in raised homes pull humid air upward year-round, and any gap in the thermal envelope becomes a path for condensation to drip onto ductwork and insulation below.
Closed cell spray foam is the choice for Port Aransas because it stops moisture and air at the same time. It cures hard, resists salt air corrosion, and does not absorb water the way open cell or fiberglass does. We spray crawl spaces under pilings, seal rim joists and band joists, insulate attics, and seal the gaps around ductwork that let humid Gulf air bypass your air handler. When old insulation is wet, compressed, or fouled, we remove it completely before any new foam goes in. We do not spray over moisture or pretend a leak will dry out later. We fix the moisture first or we walk away.
Our team has been serving Port Aransas and the Corpus Christi coast since 2012. We are fully insured with general liability and workers' compensation coverage on every job.

How a Job Works in Port Aransas
We start with a free on-site assessment. We look at your attic, crawl space, or the walls you want sealed. We measure the area, identify any moisture or old insulation that has to come out first, and we talk through whether closed cell or open cell foam is the right choice for your use. We give you a written estimate with the R-value, thickness, and board footage spelled out so you know exactly what you are paying for.
On the work day, we set up mechanical ventilation so the space stays safe during the spray. The foam cures as it hardens, and we give you a clear re-entry window, usually twenty-four to forty-eight hours, before the space is occupied again. If we are working in an occupied home, we coordinate around your schedule and your family's comfort. If insulation has to come out first, we haul it away and leave your property clean.
When we are done, we walk through with you, answer your questions, and leave you with documentation of what was installed and where. No surprises, no smell that lingers because the job was rushed.
Pricing for spray foam insulation in Port Aransas depends on what you are insulating and what has to be done first. An attic foam job typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on thickness and R-value. A crawl space under your pilings usually starts around $2,500 and goes up with square footage and depth. Rim and band joist sealing often runs $650 and up. If old insulation has to be removed first, add $950 to $2,800 depending on how much and what condition it is in. The biggest cost factors are the area you want covered, the R-value and thickness the code requires at your address, whether you choose open or closed cell, and whether we are removing and replacing existing insulation or starting fresh.
