Spray Foam Insulation in Converse - Same-Day Service, Done Right the First Time

Fast, Reliable Spray Foam Insulation Across Converse

Spray foam insulation in Converse typically costs $2,800 – $7,400 for a full attic or wall project, depending on whether you choose open-cell or closed-cell and how much of the existing insulation has to come out first. We run crews throughout Converse several days a week, so a same-week estimate is realistic and emergency rim joist work can often be scheduled within 48 hours. If you live in a 1950s – 70s ranch east of FM 1976 and the ceiling feels like a hot plate every August afternoon, the problem usually isn’t your AC. It’s the attic.

Chase Whitaker leads our Converse crews. He knows which blocks off Rocket Lane still have original single-pane windows, where the cantilevered floors trap drafts behind the knee walls, and how the humid nights near Randolph AFB punish a bad open-cell roof deck application. Local knowledge like that shows up in the work.

Why Laurel Attic Insulation San Antonio Is Converse’s Preferred Spray Foam Insulation Company

We’re the spray foam crew Converse homeowners call when another company’s work failed. Our team inspects attics in Converse weekly, and the pattern is consistent: someone sprayed over compacted cellulose without air sealing first, and now there are hot spots in the ceiling that the AC can’t touch. Our Spray Foam Insulation team starts every job by finding the bypasses. Not by spraying over them.

The Relay Visibility Guarantee applies on every Converse job. You book, you get a live arrival time, the technician is background-checked and uniformed, and before-and-after photos land in your phone. You pay from a link on the digital invoice. There’s no four-hour window and no door-knock surprise. The written price is the price.

Every Converse project carries the 365-Day Done Right Promise. If the foam separates from the rafters, if the rim joist seal fails, if the hot spots come back, we return and make it right. In writing. Free second visit if a repair fails. That’s not a warranty sentence nobody reads; it’s the core of how we work in Converse.

Spray Foam Wall Insulation in Converse

Spray foam wall insulation in Converse is most needed in the 1950s – 70s ranch homes east of FM 1976, where the original batt insulation behind the knee walls has slumped or was never installed correctly. A typical wall insulation retrofit in Converse runs $3,100 – $6,800, depending on whether we’re injecting foam into existing cavities or applying it during a remodel with stud bays exposed. The job involves removing or shifting existing drywall or siding access, air sealing the top plates and penetrations, then spraying Demilec or Icynene foam to the target R-value.

Open-Cell Wall Cavity Injection

For finished Converse walls where demo isn’t wanted, slow-rise open-cell injection gets foam behind the drywall without tearing out the original single-pane windows. It fills the cavity, air seals the top plate, and leaves your original trim intact. For older ranches where the wall cavities were never insulated, this changes how the house feels within a day.

Closed-Cell for Structural Walls

If the wall is open during a remodel or if you’re finishing a garage, closed-cell adds stiffness and acts as a vapor barrier. In Converse’s humid climate, that matters. It stops the convection losses that let hot, damp air migrate from the soffits into the wall cavities.

Rim Joist Spray Foam in Converse

Rim joist spray foam in Converse seals the cantilevered floor edges behind those ranch-style knee walls, which is where drafts, bugs, and humid air sneak into the living space. A full rim joist job in a Converse ranch typically runs $1,200 – $2,800, and in most homes it takes one day. Our crews treat the rim joist as a system: clean the surface where needed, air seal the gaps, then apply closed-cell foam to the band board and top of the foundation wall.

Cantilevered Floor Sealing

In the 1960s – 70s homes off Rocket Lane and around Randolph AFB, the cantilevered floor extends the living space past the foundation. The rim joist under those cantilevers is a major air leak. Sealing it with closed-cell foam stops cold drafts in winter and keeps treated indoor air from escaping into the humid Converse afternoons.

Crawl Space and Basement Rim Joists

Some Converse homes have pier-and-beam or partial crawl spaces. The rim joist there is exposed to ground moisture and outside humidity. Closed-cell Demilec foam locks that edge down, which reduces musty smells and keeps the floor above from feeling like a swamp cooler grid in July.

Trusted Brands We Service in Converse

We install and service spray foam from Demilec, Icynene, and CertainTeed, and we keep open-cell and closed-cell materials stocked for Converse jobs. That means when we find a failed open-cell roof deck application on a 1960s ranch near Randolph AFB, we can quote the removal and replacement the same day instead of waiting a week for material supply. Our techs are trained on the specific expansion rates and moisture handling of each brand, so the foam goes in at the right thickness and the right density for Converse’s heat and humidity. We match the material to the job and to your attic’s ventilation profile, not to whatever is already on the truck.

Common Spray Foam Insulation Problems We See in Converse Homes

• Compacted cellulose masking as AC failure: In homes near Randolph AFB, blown-in cellulose settles under intense attic heat and drops below R-13. Homeowners crank the AC, but the ceiling still radiates heat. When we air seal and spray foam the roofline, those hot spots disappear, and the AC finally cycles off.
• Open-cell foam trapping humidity at the roof deck: Converse’s muggy summer nights and poorly vented 1960s attics are a bad combination. Open-cell foam on the underside of the sheathing can hold moisture against the wood. We often find early-stage rot and a mildew smell in these attics, which is why we evaluate the ventilation before recommending open-cell.
• Two-part foam pulling away from rafters: In ranch homes east of FM 1976, contractors sometimes sprayed foam directly over old fiberglass batts. The foam shrank and separated from the wood, leaving thermal bypasses right at the top plates. The fix is removal, air sealing, and a clean application to structure.
• Foam over old cellulose without removal: Layering new spray foam over settled cellulose gives you a fresh-looking attic and the same uneven R-value underneath. In Converse, the settle rate under a hot roof deck is fast. We remove the old material first, then foam to the target depth.
