Portland sits on the bay side of the Texas Coastal Bend, where 1980s-to-2020s brick two-stories with bonus rooms over garages meet the Gulf's relentless heat and humidity. Your attic sits 140 to 160 degrees most of the year, your ductwork runs through it, and the salt-laden air outside pushes moisture inward every day. Spray foam insulation and air sealing are how Portland homeowners stop the cooling bills and the condensation that comes with it.
We have been serving Portland (78374) and the Corpus Christi area since 2012. Our team knows the bonus room that never cools, the duct runs that leak in the attic, and the damp insulation that has to come out before anything new goes in. We show up with a written estimate that names the R-value and thickness you are paying for, we do the work right, and we are reachable when you have a question.
Spray Foam Insulation in Portland (78374)
Portland's brick two-stories were built to sit on concrete slabs with vented attics above them. That vented attic is where your air handler and ductwork live, and it is where the problem starts. In summer, that attic pulls 140 to 160 degrees from the sun-baked roof and the western exposure, and every degree of that heat leaks down through your ceiling into the rooms below. The bonus room over the garage and the back bedroom that faces west are the ones that never cool, no matter how hard the air conditioning runs. In winter and during the tropical season, the Gulf humidity condenses on the underside of the metal roof and drips onto the insulation below. Over time, that insulation compresses, loses its R-value, and becomes a sponge.
Closed cell spray foam solves both problems at once. It seals the air leaks that let hot attic air down into your home, it stops the moisture from condensing in the first place, and it does not compress or sag over time. For a bonus room or a west-facing bedroom, spray foam in the rim joist and band joist around that space, plus air sealing in the attic above, often makes the difference between a room that is uncomfortable and one that is livable.
We have been insulating Portland homes and commercial buildings since 2012. We know which attics have room to work and which ones are tight, which walls have cavities and which ones need injection foam, and which crawl spaces and garages need to be sealed before the summer heat sets in.

How a Job Works in Portland
We start with a free on-site assessment. You walk us through the space, you tell us what is uncomfortable or what the bills look like, and we measure the area, check what is already there, and look for air leaks. We ask about your building permit requirements and whether your home has an HOA that governs exterior work. We come back with a written estimate that tells you the R-value, the thickness we will spray, the type of foam (open or closed cell), and the price.
On the day of the work, our crew shows up with the equipment, the drums of foam at the right temperature, and a plan. If there is old insulation that has to come out first, we remove it, haul it away, and clean the space. We spray the foam in controlled passes, we maintain the thickness you paid for, and we keep mechanical ventilation running the whole time. For attic foam, we also install the ignition and thermal barriers that the local building code requires. Once the foam has cured (usually 24 to 48 hours), the space is yours again.
We leave your property clean. No foam scraps on the floor, no overspray on your belongings, and no mess in the yard.
Attic spray foam in Portland typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on the thickness and R-value you need. A typical attic on a two-story runs 800 to 1,200 square feet, so you are looking at a range of $1,200 to $1,800 for open cell, or $1,000 to $1,500 for closed cell, before any insulation removal. If old insulation has to come out first, add $950 to $1,200 depending on how much there is. Wall injection foam for a bonus room or a closed cavity runs from $2 per square foot. Crawl space foam starts at $2,500. Rim and band joist sealing for a bonus room or a west-facing wall starts at $650. The exact price depends on the area to cover, the R-value you want, whether anything has to be removed first, and how easy our crew can access the space. We give you a free estimate over the phone at (361) 278-8446, and a detailed written estimate on site with no obligation.
