How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes solid insulation products, but San Antonio’s heat and humidity expose weak points you won’t read about on a manufacturer spec sheet. Here’s what we actually see in attics across San Antonio:

• CertainTeed CertaSpray open-cell shrinkage in high-heat attics. Open-cell foam can pull slightly away from rafters after repeated 130°F-plus attic temperature swings, creating hairline gaps where conditioned air escapes. We see this most in Alamo Heights and Terrell Heights homes with dark shingle roofs. The fix is a targeted re-fill of the separated areas, not a full tear-out.
• CertainTeed closed-cell foam lifting from OSB roof decking due to trapped moisture. In San Antonio’s spring humidity, closed-cell applied over a damp deck can delaminate in patches. This shows up as hollow-sounding spots when you tap the foam. We cut out the lifted section, verify the deck is dry, and re-spray with proper surface prep.
• Rim joist spray foam gaps at the band board in pier-and-beam homes. Older San Antonio homes near Monte Vista and Government Hill often have irregular joist spacing. A sloppy original install leaves gaps at the rim joist that bleed cold air into crawlspaces. We re-fill and tool the foam flush.
• CertainTeed CertaSpray off-ratio application from rushed installs. When the A and B chemical mix is off, the foam stays tacky or crumbles over time. You’ll notice a chemical smell that won’t fade or foam that never fully hardened. We test the existing foam, identify the bad sections, remove them, and re-spray with correctly calibrated equipment.
• Garage ceiling spray foam delamination above unconditioned garages. In San Antonio, garages hit 115°F regularly. Foam applied directly to a garage ceiling without a thermal barrier or over-painted drywall can peel in sheets. We address the adhesion surface first, then re-apply.

Our CertainTeed Spray Foam Insulation Process

Here’s exactly what happens when you call us about CertainTeed spray foam insulation in San Antonio:

1. 1
   Call and talk to a person. A live person answers 24/7. We ask about your home’s age, the area you’re insulating, and what you’re seeing now.
2. 2
   On-site inspection. Garrett Sloane or one of our background-checked techs comes out, goes into the attic or crawlspace, and measures the actual surface area. We check existing foam depth, look for the failure modes above, and photograph everything.
3. 3
   Written price before work starts. You get a line-item price on paper. No verbal estimates, no “we’ll see how it goes.” The number you see is the number you pay.
4. 4
   Prep and application. We mask off the work area, run ventilation, and apply the foam to manufacturer spec. For CertainTeed work, we match the foam type to what’s already there so expansion rates and R-values stay consistent.
5. 5
   Post-install verification. We check depth, adhesion, and coverage with a thermal camera in key spots. You see the before-and-after, not just a bill.
6. 6
   365-Day Done Right Promise in writing. If anything fails within a year, we come back and fix it free. That covers labor and materials.
