Missouri City's 1980s and 1990s ranch homes and two-stories sit on slab-on-grade foundations with vented attics that bake at 130-150 degrees from May through October, and that radiant heat is the single biggest driver of cooling bills across ZIP 77489. Your attic ductwork runs through that same unconditioned space, losing conditioned air before it reaches the rooms that need it, and your insulation is fighting a losing battle against Gulf Coast humidity year-round.
Homeowners in Missouri City call Houston Spray Foam Insulation because we know exactly what's happening in your attic and crawl space, and we have the experience to fix it right. We've been serving the Houston area since 2012, and we understand the specific challenges of your neighborhood: the radiant heat load, the moisture that comes with our climate, and the comfort and efficiency problems that show up when standard insulation gets old or settles.
Spray Foam Insulation in Missouri City (77489)
Missouri City's housing stock from the 1980s forward is built almost entirely on slab-on-grade foundations with vented attics and ductwork routed through unconditioned space. That means your cooling system has to condition the attic air before it can condition your home. In summer, attic temperatures routinely exceed 140 degrees, and your air leaks out through gaps around ductwork, through unsealed rim joists, and through the gaps in old fiberglass batts that have settled and separated over thirty years. Humidity is constant here: summer moisture drives vapor into your walls and attics from the outside in, and condensation forms on cool surfaces inside insulation and crawl spaces when the air conditioning runs. Standard blown-in fiberglass or cellulose absorbs that moisture, compacts, and loses R-value. Spray foam seals the air leaks that fiberglass cannot touch, and it does not absorb moisture or settle.
Our team has been installing closed-cell and open-cell spray foam in Missouri City attics, sealed roof decks, rim joists, and crawl spaces since 2012. We know which type of foam makes sense for your home, your budget, and your specific moisture and temperature challenge. We show up with a written estimate that names the R-value and thickness we are installing, and we leave your property clean and ready to use.

How a Job Works in Missouri City
Step 1: We schedule a free on-site assessment at your Missouri City address. We walk your attic and crawl space, we look at your ductwork and existing insulation, and we measure the areas to be sprayed. We ask about your comfort problems, your energy bills, and whether you have moisture or condensation anywhere. That assessment takes about 30 minutes, and we leave you with a written estimate that shows the R-value per inch, the total thickness we recommend, the square footage or board footage, and the price.
Step 2: On the day of the work, our team sets up mechanical ventilation to manage the cure environment. We spray the foam at the manufacturer ratio and temperature, in controlled passes to hit the thickness and R-value on your estimate. If your attic or crawl space has old insulation that has to come out first, we remove it and haul it away. If there is moisture or a damp substrate, we stop and tell you straight: we fix the moisture first or we walk away. Once the foam is sprayed, we set a re-entry window of 24 to 48 hours before the space is safe to occupy or work in again.
Step 3: We clean up the work area, we walk the job with you, and we answer your questions about the finished work. You get a warranty on our workmanship, and we leave you with documentation of what we installed.
Pricing for spray foam insulation in Missouri City depends on the area to be covered, the R-value and thickness you need, whether you are using closed-cell or open-cell foam, and what has to be removed or repaired first. A typical attic foam job in a Missouri City home runs from $1.50 per square foot for open-cell foam to $1.20 per board foot for closed-cell, depending on depth. Wall injection foam for closed walls with no cavity insulation starts around $2 per square foot. Crawl space encapsulation and sealing typically runs $2,500 and up. If you have old insulation that needs to come out before new foam goes in, removal starts at $950. The best way to get a real number is a free on-site estimate: call us at (346) 322-2588, and we will walk your home, measure the spaces, and give you a price in writing with R-value and thickness spelled out.
