This page is for CertainTeed product owners in Los Angeles who need a blower-door test, thermal imaging inspection, insulation inspection, or duct leakage test - whether your home was built with CertainTeed materials originally or a previous installer used their batts, blown fiberglass, or spray foam. We are an independent CertainTeed service provider, not affiliated with or authorized by CertainTeed Corporation.

How CertainTeed Products Fail - and How We Fix Them

• CertainTeed InsulSafe SP blown fiberglass settles below labeled R-value in Los Angeles attics. The loose-fill product is rated at a settled density that assumes moderate humidity; in Los Angeles, where attic temperatures routinely hit 140°F in August and winter moisture intrudes through unsealed soffit chases, we’ve measured InsulSafe SP at 2.3 inches below specified depth on 12-year-old installs. We remove the settled material, seal all top plates and can-light penetrations, then reinstall to true depth with fresh blown fiberglass or cellulose.
• CertainTeed SpeedyR rotary vane feeders leave gaps at attic hatch perimeters and chimney saddles. The machine’s 2.5-inch hose diameter can’t negotiate tight geometry around framed obstructions; we find cold bands at these boundaries on thermal imaging. Our crew hand-packs Rockwool or dense-pack cellulose into these dead zones after air sealing, then verifies with follow-up infrared.
• CertainTeed CertaSpray open-cell foam shrinks 3-5% in coastal Los Angeles zones with marine layer exposure. The foam was applied at 5.0 inches in a Redondo Beach crawl space we audited last March; by October, gap separation at rim joists was visible to the eye. We trim the failed foam, seal the gaps with closed-cell touch-up, and document the repair with photo records.
• CertainTeed MemBrain smart vapor retarder delaminates when installed over damp kraft-faced batts in unvented knee walls. This is common in 1950s ranch-style homes in the Leimert Park corridor, where Wes Okafor and our crew have retrofitted dozens of assemblies. The MemBrain adhesive fails where condensation collects behind the facing; we remove the compromised retarder, dry the cavity with targeted ventilation, then reinstall with proper perm rating for the assembly.
• CertainTeed OPTIMA dense-pack cellulose bridges in balloon-framed walls with wire chases. The product needs 3.5 PSI net density to achieve its stated R-value; in walls with horizontal wiring, the material packs around obstructions and leaves voids. We snake the cavity with a borescope, identify the bridge location, then re-blow with adjusted pressure and a smaller-diameter fill tube.

Our CertainTeed Home Energy Audit Process

1. 1
   Call and scheduling. A live person answers, 24/7. We book a two-hour window and text you when the technician is en route - Haven Standard: Arrive on schedule, named technician, no callback windows measured in business days.
2. 2
   Visual and thermal inspection. We walk the attic, crawl space, and conditioned envelope with a FLIR thermal camera, looking for CertainTeed-specific failure signatures: settled blown fiberglass, shrinkage gaps in CertaSpray, delaminated MemBrain, bridging in OPTIMA walls.
3. 3
   Blower-door test. We run a pressurization diagnostic - a blower-door test that shows, in one number, how much air your building envelope is losing. Typical pre-sealing readings in Los Angeles homes run 3,500-6,000 CFM50; we record yours and flag where the air is moving.
4. 4
   Written scope and price. Before any work starts, you get a flat price, written scope, and written warranty. This is Haven Standard Clause 1. No exceptions.
5. 5
   Air sealing first, then insulation. Seal the holes first. Then measure the R-value. In that order. We seal top plates, can lights, penetrations, and bypasses before adding or replacing any insulation material.
6. 6
   Post-work blower-door test and documentation. On applicable jobs, we run the blower door again and publish the before-and-after numbers. You walk away with a written summary showing ACH50 change, installed R-value, product data sheets, and a Documented Photo Record.
