Baytown's older ranch neighborhoods run slab-on-grade with vented attics that hit 140-plus degrees from May through October, and those empty wall cavities that were never filled are costing you real money every month. Houston Spray Foam Insulation has been serving Baytown and the surrounding Houston area since 2012, and we know exactly what happens when a 1960s or 1970s brick ranch loses its original attic insulation to settling and compression.
When your cooling bill climbs and a room over the garage stays hot no matter what your AC does, or when you spot damp insulation or condensation in the attic or crawl space, that is when Baytown homeowners call us. We spray closed-cell and open-cell foam, seal the air leaks that let conditioned air escape, and pull out failed insulation before we start fresh. Our team is fully insured, and we show up with written estimates that name the R-value and thickness so you know exactly what you are getting.
Spray Foam Insulation in Baytown (77520)
Baytown sits in the industrial belt between the Energy Corridor and the Ship Channel, and the housing stock runs the full spectrum: older ranch homes on slab with vented attics, some industrial and commercial properties, and newer residential scattered through. The challenge is always the same. Your attic is not conditioned space. It is a heat sink in summer and a humidity trap year-round. Ductwork runs through it because that is how the houses were built, and every foot of duct in a 145-degree attic loses cooling before it reaches the room you are trying to condition. The Gulf Coast humidity means moisture comes at your insulation from the outside in, especially in spring and after rain. If your attic insulation has been there since 1975, it has settled into a pancake. If you have wall cavities with no insulation at all, that is a direct path for heat and humidity into your living space. Crawl spaces under slab-on-grade homes sweat in summer and pull moisture up through the rim joist and band joist into the first floor. We have been sealing and insulating these exact problems in Baytown for over a decade.

How a Job Works in Baytown
We start with a free on-site assessment. Our team walks your attic, crawl space, or the walls you want sealed, and we listen to what is happening. Is your insulation wet or matted? Does the attic smell musty? Is one room always the wrong temperature? We measure the space, check for moisture, and talk through whether you need closed-cell foam (higher R-value per inch, vapor barrier properties, and the right choice for a damp attic or crawl space) or open-cell foam (lower cost, breathable, and the right call for a dry attic that just needs R-value). Then we give you a written estimate with the R-value, thickness, and price before we touch anything.
On the job, we show up with the equipment and crew to spray. If insulation has to come out first, we remove it and haul it away. We set up mechanical ventilation so the smell during cure does not drift into your living space. We spray the foam at the manufacturer ratio and drum temperature, layer by layer, to the thickness and R-value in your estimate. The work is dirty and technical, and we manage it so you can stay in the house. Most jobs in Baytown are attics or crawl spaces, and access can be tight in those older ranch homes, so we plan accordingly.
When the foam has cured, we walk through with you, clean up the property, and answer any questions. We leave your attic or crawl space clean and ready. The re-entry window is typically twenty-four to forty-eight hours before you use the space normally.
Attic spray foam in Baytown runs from around $1.50 per square foot for open-cell to higher for closed-cell, depending on the R-value you need and whether insulation has to come out first. A typical 1,500-square-foot attic top-up with open-cell foam starts around $2,250 to $3,000. Closed-cell is more, but it handles moisture and gives you a vapor barrier, which matters in our climate. Wall injection foam for those empty cavities in your 1960s ranch runs from $2 per square foot. Crawl space foam starts at $2,500 and goes up with the area and moisture conditions. If you have failed insulation that needs to come out, removal runs from $950 depending on how much there is. The biggest cost factors are the square footage, the R-value you are targeting, whether you need closed-cell or open-cell, and what has to be removed or repaired first.
