League City's 1990s and 2000s two-story homes sit in the thick Gulf Coast humidity, where a leaky attic and undersized insulation turn your cooling bill into a monthly shock from May through October. Our team has been sealing and insulating attics, crawl spaces and walls across League City and the surrounding Houston area since 2012, and we know exactly what happens when a sealed roof deck or a vented attic loaded with ductwork sits unprotected in 140-degree heat.
Homeowners in 77573 call us because their energy bills have climbed past what they can justify, because a bedroom over the garage or at the end of a duct run never reaches temperature, or because they have spotted condensation and damp insulation in the attic or crawl space. We show up, we listen, and we give you a written estimate with R-value and thickness specs so you know exactly what you are paying for.
Spray Foam Insulation in League City (77573)
League City's housing stock tells the story: two-story colonials and brick ranches built from the mid-1990s onward, most sitting on slab-on-grade foundations with bonus rooms over garages and vented attics where the ductwork runs. Your attic temperature climbs to 130 to 150 degrees Fahrenheit during the Houston summer, and every degree of heat that escapes through undersized or settled insulation pulls cold air out of your home and across your cooling system. The humidity is relentless, especially near the bay, and condensation forms wherever warm, moist air meets a cold surface. If you have fiberglass batts or blown-in cellulose that has flattened over twenty years, or if you have closed walls with no cavity insulation and no way to add it without opening studs, spray foam is the answer that actually works.
We have been doing this work in League City and across the Houston area for over a decade. We spray attics and sealed roof decks, inject foam into closed walls, seal crawl spaces, and air-seal the rim joists and band joists where conditioned air leaks straight into the rim space. We remove old, wet or contaminated insulation and replace it correctly. We do the work right the first time, and we show up when we say we will.

How a Job Works in League City
We start with a free on-site assessment. We walk your attic or crawl space, we look at what is there now, we measure the square footage and the depth we need to hit to reach your R-value target, and we talk honestly about whether the substrate is clean and dry. If there is old, wet or contaminated insulation, we tell you upfront that it has to come out before any foam goes in. We give you a written estimate with R-value and thickness specified, so you know what you are paying for and why.
On the day of the work, our crew arrives with equipment and material staged for the job. We set up mechanical ventilation to manage fumes during the spray, we mask off areas that should not be sprayed, and we apply the foam in controlled passes at the manufacturer's ratio and temperature. Most League City homes are occupied during the work, so we coordinate the timing and we respect the re-entry window: typically twenty-four to forty-eight hours before the space is safe to use again. If your attic is tight or your crawl space is low, we plan for that. If we are working around existing ductwork or around an HVAC unit, we work carefully and we protect everything that should not be sprayed.
When the foam has cured, we clean up completely. We remove tape, we sweep, and we leave your property the way we found it, except sealed and insulated. We walk through the finished work with you so you can see what was done and why it matters.
Pricing for spray foam insulation in League City depends on the area you want to cover, the R-value you need to hit, whether you choose open cell or closed cell foam, and what has to be removed or prepped first. A typical attic spray foam job in a League City two-story runs from $1.50 per square foot for a straightforward top-up to more if the space is tight or if old insulation has to come out first. Closed cell foam, which is denser and handles humidity better, starts at $1.20 per board foot. Open cell foam, which is lighter and less expensive, starts at $0.55 per board foot and works well in many League City attics where the roof deck is already sealed. Wall injection foam for closed cavities runs from $2 per square foot. Crawl space spray foam starts at $2,500 for a typical League City foundation. Insulation removal, if the old stuff has to come out, starts at $950. A rim joist and band joist air seal starts at $650.
