Friendswood's established neighborhoods run 1970s and 1980s brick ranches and two-story homes built on slab foundations with vented attics that bake at 130 to 150 degrees from May through October, and that original attic insulation has long since settled and lost its R-value. When your cooling bill climbs and rooms over garages or at the end of duct runs stay hot no matter what the thermostat says, spray foam insulation and air sealing are the fix that works.
Houston Spray Foam Insulation has been serving Friendswood and the surrounding Houston area since 2012. We know the building stock here, the humidity that drives condensation into crawl spaces and attics, and what it takes to seal and insulate a home so it holds temperature and stays dry. Our team is fully insured, works year-round, and we show up with written estimates that spell out R-value and thickness so you know exactly what you are paying for.
Spray Foam Insulation in Friendswood (77546)
Friendswood homes built in the 1970s through 1990s were insulated with fiberglass batts and blown-in cellulose that have settled, compacted and lost their insulating power. Your attic ductwork runs through unconditioned space that hits 140 degrees in summer, and every foot of duct that is not sealed leaks cold air into the heat before it reaches your bedroom. Crawl spaces under slab-on-grade homes sweat with humidity from the Gulf Coast, and walls that were never insulated when built stay cold in winter and hot in summer. Spray foam seals air leaks that fiberglass cannot touch, and closed-cell foam in an attic or crawl space stops moisture before it condenses on wood and insulation.
We have sealed and insulated hundreds of Friendswood attics, crawl spaces, rim joists and garage walls. We know which spaces need closed-cell foam for moisture control and which can use open-cell for cost efficiency. We remove contaminated or failed insulation before we spray, and we leave your home clean and ready to occupy within 24 to 48 hours of application.

How a Job Works in Friendswood
You call us at (346) 322-2588 or request a free estimate online. Our team visits your home, inspects the attic, crawl space or walls, takes measurements, and discusses your comfort issues and energy goals. We look for moisture, air leaks, and insulation that needs to come out. We give you a written estimate with R-value and thickness specifications so you understand the scope and cost before work begins.
On the day of the job, we set up mechanical ventilation in your attic or crawl space to manage fumes during application. We spray foam to the thickness and coverage specified in your estimate, controlling the application rate and drum temperature so the foam cures properly. If insulation has to be removed first, we bag it and haul it away. We seal rim joists, band joists, rim board gaps and any air leaks around ductwork, electrical penetrations and plumbing. The work typically takes one day for an attic or crawl space, and we observe a 24 to 48 hour re-entry window before you move back into the space.
We clean up all debris, sweep and vacuum the work area, and walk through with you to confirm the job is complete. You are left with a sealed, insulated home that holds temperature and stays dry.
Attic spray foam insulation in Friendswood typically runs from $1.50 per square foot for open-cell to $1.20 per board foot for closed-cell, depending on the area to cover and the R-value you need. A 1,500-square-foot attic with 6 inches of closed-cell foam usually costs between $4,500 and $7,000. Crawl space foam starts at $2,500 and scales with square footage and depth. Wall injection foam and rim joist sealing run from $650 to $2,000 depending on access and linear footage. Insulation removal costs from $950 depending on volume and haul-away. The biggest cost factors are the square footage or board footage to cover, the R-value thickness you choose, whether existing insulation has to come out first, and how tight the access is. We measure on site and price per board foot or square foot based on the actual work. Call us at (346) 322-2588 for a free estimate with firm pricing for your Friendswood home.
