Brenham's mix of 1880s Victorians, 1940s-70s bungalows, and newer ranch homes sit on pier-and-beam foundations over open crawl spaces or on concrete slabs, with attics that pull in humid air all summer long and ductwork that runs through spaces hitting 130-160°F from June through September. When that attic insulation compresses, settles, or gets wet, your cooling bill climbs and your back bedroom never cools down.

College Station Spray Foam Insulation has been serving Brenham and Washington County since 2012. We know the local building stock, the humidity that sweats metal buildings and the underside of ducts, and what it takes to seal and insulate a historic pier-and-beam home or a modern ranch without tearing into walls or running ductwork. We're fully insured, we work year-round, and we show up when we say we will.

Spray Foam Insulation in Brenham (77833)

Brenham's older homes were built to breathe. Those 1880s-1930s Victorians and frame bungalows raised on piers over open crawl spaces were never meant to have sealed attics or closed-cell foam in the rim joists, but they need it now. Summer humidity condenses on the underside of the roof deck or on ductwork running through an unconditioned attic. Winter hard freezes burst water lines that run through vented attics. And in the barns and metal buildings scattered across Washington County ranches outside town, condensation drips from the interior of the metal skin when there's no closed-cell foam to break the thermal bridge and stop the sweat.

We spray open-cell foam in attics where ventilation and moisture control are working correctly, and closed-cell foam in rim joists, crawl spaces, and metal buildings where the thermal barrier and the vapor seal are what matter. We remove compressed, wet, or rodent-fouled insulation before we spray anything new. We work in tight crawl spaces under pier-and-beam homes, in attics with low headroom and tricky rafter spacing, and in bonus rooms over garages where the original insulation has failed. Since 2012, we've helped Brenham homeowners and property managers cut cooling loads, stop condensation, and make their homes and barns perform.

How a Job Works in Brenham

We start with a free on-site assessment. You show us the space, describe what's not working (high bills, a cold room, condensation, or insulation that's seen water), and we walk through the attic, crawl space, or metal building with you. We measure, take photos, and explain what we see: whether the ductwork is leaking, whether the existing insulation is compacted or wet, whether we're looking at a top-up or a full removal and replacement, and what the local code requires at your address. We give you a written estimate with R-value and thickness specs, so you know exactly what you're paying for.

On job day, we set up mechanical ventilation to run during cure and for the re-entry window you'll need to observe (typically 24 to 48 hours). We spray the foam to the thickness and density you've approved, we seal air leaks around rim joists, band joists, ductwork, and penetrations, and we install the thermal barrier if code requires it. If insulation has to come out first, we remove it, haul it away, and leave the space clean before we spray. We work around your schedule and your family's comfort, and we leave your property clean when we're done.

Pricing in Brenham depends on the scope of work and what you're starting with. An attic top-up of open-cell foam in a 1,200-square-foot home typically runs $1,800 to $3,600, starting at $1.50 per square foot. A crawl space spray foam job under a pier-and-beam home starts at $2,500 and climbs with the square footage and the condition of what's underneath. Rim and band joist sealing on an older home runs $650 to $1,500. If insulation has to come out first (wet blown-in, rodent-fouled material, or old fiberglass), removal starts at $950 and replacement and re-insulation starts at $2,800. Metal building and barndominium spray foam runs from $1.75 per square foot. The real cost drivers are the area to cover, the R-value and thickness you need, whether you're using open or closed-cell foam, and what has to be removed or repaired before we spray. Call us at (979) 406-5185 for a free estimate. We'll walk through your space, explain what we see, and give you a firm price in writing.

I have a 1920s Victorian on Crockett Street with a pier-and-beam foundation and an open crawl space. The crawl space is damp in summer, and I'm worried about the rim joists rotting. What do we do?

That's a common situation in older Brenham homes. We inspect the crawl space to check for standing water, active leaks, or soil moisture issues. If the space is damp but draining, we can spray closed-cell foam on the rim and band joists and the interior perimeter to create a thermal and vapor barrier. That stops condensation from forming on the wood and cuts the moisture load. If there's standing water or a drainage problem, we address that first or we walk away. Closed-cell foam is the right choice here because it's a vapor barrier and it resists moisture. Call us at (979) 406-5185 and we'll schedule a crawl space inspection.

My attic insulation is compressed and smells like mold. Can you just spray foam over the top of it?

No. Compressed, wet, or moldy insulation has to come out before anything new goes in. If we spray over it, we're trapping moisture underneath, and the problem gets worse. We remove the old insulation, haul it away, inspect the attic deck for moisture or roof leaks, let it dry if needed, and then spray the new foam to the thickness and R-value you need. Removal is the first step, and it's the honest one. Call us at (979) 406-5185 to discuss what you're seeing.

What does spray foam cost for an attic in Brenham, and what affects the price?

Attic spray foam starts at $1.50 per square foot for open-cell foam. A typical 1,200-square-foot attic might run $1,800 to $3,600 depending on the R-value you need, the thickness we spray, and whether the existing insulation has to come out first. Removal adds $950 to $1,500. The key factors are the area to cover, the R-value and thickness your local code requires, access to the attic (tight spaces cost more), and whether there's old insulation to remove. We give you a written estimate with all the specs before we start. Call (979) 406-5185 for a free on-site quote.

Who decides what R-value and thickness I need in my Brenham attic, and how do I know the work meets code?

The energy code in force at your address sets the minimum R-value for attic insulation. The building official at the City of Brenham enforces it. We follow the code that applies to your home, and we include the R-value and thickness in our written estimate so you know exactly what you're getting. If you need a permit (some attic work does, some doesn't), we help you navigate what applies at your address, but the City of Brenham website has the specifics on permits and contractor registration. The ignition barrier and thermal barrier rules are also set by the building code and the building official, not by us. We install what code requires.

Can we stay in the house while you spray foam the attic?

Yes, but with a re-entry window. We set up mechanical ventilation during the spray and cure process. Most homeowners can re-enter the attic space after 24 to 48 hours, depending on the foam type and the temperature. We'll tell you the specific window when we schedule the job. You can stay in your home and go about your day, but the attic is off-limits until cure is complete. If you have an occupied bonus room or bedroom directly under the attic, we coordinate the timing so the spray and ventilation don't interfere with your comfort.

Are you insured for spray foam work at my Brenham property?

Yes. We are fully insured with general liability and workers' compensation coverage. Our team is protected and your property is protected. When you call for an estimate, we can provide proof of insurance. Any contractor doing spray foam work in Brenham should carry full insurance and be able to show it to you before work begins.

Summer cooling bills in Brenham are brutal. When should I plan a spray foam job, and will it really help?

June through September is peak cooling season in Brenham, and that's when an attic hitting 140-160°F makes your air conditioner work hardest. If your attic insulation is compressed, thin, or missing in spots, you're losing conditioned air through the roof and pulling hot air down into your living spaces. Spray foam stops that leakage and raises the R-value. Spring (March-May) and fall (October-November) are the best times to schedule the work because the weather is mild and we can ventilate properly during cure. If your bills are high right now, we can assess your attic and give you a realistic idea of what foam can do. Typical energy savings run 15 to 40 percent depending on what you start with, but we never guarantee a number. Call (979) 406-5185 to schedule an inspection.
