How CertainTeed Products Fail - and How We Fix Them

• CertainTeed CertaSpray Open-Cell in vented Lancaster attics: The material itself doesn’t fail, but it’s often installed over unsealed top plates and can-light penetrations. In Lancaster’s 130-degree July attics, conditioned air bleeds through those gaps faster than the foam can stop it. We pull back existing CertaSpray where needed, seal every penetration with fire-rated caulk and rigid foam baffles, then reinstall or supplement. The R-value you paid for is only as good as the air barrier behind it.
• CertainTeed CertaSpray Closed-Cell in garage ceiling applications: We regularly see this in West Lancaster homes built 2015-2019 where the original contractor sprayed directly onto unprimed drywall or dusty OSB. Adhesion fails in patches, creating voids that show up on thermal imaging as cold stripes. We scarify the failed areas back to substrate, apply a compatible primer, then respray with matched density foam.
• CertainTeed IntelliBrite rigid foam board transitions: Homeowners near Avenue K and the BLVD often have IntelliBrite polyiso on their roof decks with gaps at the ridge beam where spray foam was supposed to complete the seal. Thermal bridging at those joints kills the assembly performance. We remove the compromised transition, re-cut the polyiso for a tighter fit, then bridge with closed-cell spray foam to restore continuity.
• CertainTeed MemBrain smart vapor retarder delamination: In Lancaster’s high-desert climate with 30-degree winter swings, MemBrain installed backward or without proper overlap tape can peel at seams. Once the retarder fails, moisture drives into the spray foam cavity. We strip the failed membrane, verify the cavity is dry with a moisture meter, then reinstall with proper orientation and taped seams before touching any foam.
• CertainTeed Optima blown-in fiberglass over-spray situations: Not a spray foam product, but we find it constantly in Lancaster attics where a previous contractor blew Optima right up to the eaves without air sealing first. When we come in to add spray foam for a conditioned attic conversion, that loose fill has to come out cleanly or it contaminates the spray application. We HEPA-vacuum the Optima, seal, then spray.

Our CertainTeed Spray Foam Insulation Process

1. 1
   Call and schedule. A live person answers 24/7. We book a site visit, usually within 48 hours.
2. 2
   Pre-install air-leak audit. Wes Okafor runs a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. We photograph every penetration, top plate gap, and can light. You get the photos and the CFM50 reading in writing before we quote.
3. 3
   Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No work starts without it.
4. 4
   Air sealing first, then insulation. We seal all top plates, electrical and plumbing penetrations, and duct boots with fire-rated caulk, rigid foam, or tape as appropriate. Only then do we spray.
5. 5
   Spray foam application. We match CertainTeed density and chemistry where we’re integrating, or specify why we’re deviating. Temperature and substrate conditions are logged.
6. 6
   Post-test and documentation. Second blower-door test, thermal imaging verification, Documented Photo Record delivered to you. Before-and-after numbers are published on every job.

What CertainTeed Spray Foam Insulation Costs in Lancaster

These are real ranges for jobs we’ve completed in Lancaster neighborhoods including the areas around Avenue K, Quartz Hill, and West Lancaster:

• Open-cell spray foam, vented attic (1,200-1,800 sq ft): $2,800 – $4,200

• Rim joist closed-cell, crawl space or basement perimeter: $1,800 – $3,200
• Spray foam roof deck, conditioned attic conversion: $5,500 – $9,000
• Air sealing + spray foam integration with existing CertainTeed materials: add $800 – $1,500

What moves the price: accessibility (steep roof pitch or tight crawl space), substrate prep (scarifying failed foam, removing contaminated loose fill), and whether we’re integrating with existing CertainTeed products or starting fresh.
