CertainTeed Home Energy Audit in Campbell: What to Know First
We provide independent CertainTeed home energy audit in Campbell, typically scheduled within 48 hours and completed in a single visit. Most audits run between $280 and $520 depending on home size and which diagnostics are needed. We publish before-and-after blower-door numbers on every applicable job so you see the performance change, not just a report saying “improved.”
This page is for Campbell homeowners who have CertainTeed insulation, air barriers, or building envelope products and need to know why their upstairs still runs hot, their PG&E bill keeps climbing, or a prior contractor’s “solution” didn’t hold. We don’t sell audits as a lead tool - we use them to find the leaks that waste the insulation you’ve already paid for. Call (831) 534-3206 or text us to book. We’re in Campbell neighborhoods weekly, from the Pruneyard Plaza corridor over to the older ranch homes near San Tomas Aquino Creek.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed MemBrain smart vapor retarder delamination in Campbell’s marine climate. The humidity-responsive polyamide layer can separate from its kraft paper backing in homes with seasonal attic moisture swings, common in Campbell’s Mediterranean climate where winter marine layer meets summer dry heat. We find this with infrared scanning during our audit, then replace with intact MemBrain or shift to a more stable retarder if the attic ventilation can’t be improved.
- CertainTeed InsulSafe SP blown-in fiberglass settling below labeled R-value. This product is rated at R-2.5 per inch settled, but we regularly measure 15-20% below that in Campbell attics where installers skipped pre-installation air sealing. The fiberglass migrates through gaps in top plates and around can lights. We remove the settled material, seal every penetration with fire-rated caulk and foam, then reinstall to true depth.
- CertainTeed CertaSpray open-cell foam shrinkage at rim joists. Early batches of this open-cell product shrank 3-5% during cure, pulling away from framing in crawl spaces and basement rim joists. Our audit includes probe testing at these junctions; where we find gaps, we cut back the failed foam and reapply with current-formulation CertaSpray or shift to closed-cell if moisture drive demands it.
- CertainTeed SwiftSeal tape failure on rigid foam seams. The acrylic adhesive breaks down in attics that exceed 140°F, which happens in Campbell’s unvented cathedral ceilings during September heat events. We find these gaps with blower-door-directed infrared, then re-tape with foil-faced acrylic that handles sustained high temp, or switch to fluid-applied seam sealant where geometry allows.
- CertainTeed TrueComfort batt compression in 2×4 walls with added exterior foam. Homeowners in Campbell’s 1960s-70s neighborhoods often add rigid foam outside without resizing interior batts, compressing the TrueComfort and dropping its effective R-value by 30% or more. Our audit measures actual in-wall performance with infrared and calculates whether the assembly meets Title 24; if not, we specify proper-density batts or dense-pack cellulose.
Our CertainTeed Home Energy Audit Process

- 1
Call and scope. You text or call (831) 534-3206. We ask square footage, year built, known problem rooms, and whether you have prior audit reports. We schedule within 48 hours, usually sooner.
- 2
Pre-test blower door. We run a pressurization test - a measurement that shows, in one number, how much conditioned air your building envelope is losing. In Campbell’s 1950s-70s housing stock, we typically see 3,500-5,500 CFM50 before any work.
- 3
Infrared and visual inspection. We scan with FLIR for thermal bypasses, inspect CertainTeed product condition and installation quality, and photograph every finding. You get these photos in your report.
- 4
Duct leakage test if indicated. When the audit shows supply ducts in an unconditioned attic - common in Campbell - we run a duct blaster to quantify leakage to outside. CertainTeed’s duct wrap doesn’t fix a disconnected collar.
- 5
Written findings and price. Before we leave, you get a written scope with line-item pricing, predicted blower-door improvement, and our recommendation on whether repair or full replacement makes sense. No work starts without your written approval.
- 6
Post-work verification. If you hire us for the fix, we run the blower door again and hand you a printed report with both numbers. Seal the leaks first. The insulation has nowhere useful to go until you do.

Homes near the older Campbell corridors - think Hamilton Avenue west of Bascom - often need more extensive top-plate sealing due to balloon framing variants common in that pocket. That adds labor but shows up in the written price before any work starts, always. Call (831) 534-3206 for your exact number; estimates are free.
Why Campbell Homeowners Call Topside Attic Insulation Campbell for CertainTeed Work

We’ve served Campbell since 2016, and the jobs near Pruneyard Plaza taught us early that homes this age carry air-sealing problems that show up long before you touch a bag of blown-in cellulose. Wes Okafor runs a blower-door test before and after every applicable job, and hands you a printed report with both numbers so there’s no ambiguity about what changed.
We’re independently owned and operated - not a franchise, not a CertainTeed authorized dealer. That means we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber with no proprietary lock-in. If your CertainTeed product failed because it was the wrong product for the assembly, we’ll say so and specify something that works. Our 365-Day Done Right Promise applies to all completed work, and a live person answers calls 24/7. We also service Reflectix products if your audit reveals radiant barrier issues alongside the CertainTeed work.
FAQs
No. As an independent CertainTeed service provider, our audit is diagnostic only and doesn’t alter installed products. If we find a manufacturing defect during inspection, we document it with photos and note the original install date so you can pursue a warranty claim directly with CertainTeed if coverage applies. Call (831) 534-3206 to schedule - we’ll flag any warranty-relevant findings in your written report.
Usually within 48 hours of your call, sometimes next-day. We keep routes tight in Campbell and nearby San Jose, Los Gatos, and Saratoga. Same-week scheduling is normal; we don’t do urgency theater with fake scarcity. Text or call (831) 534-3206 to check today’s availability.
Repair is cheaper when the product is intact but poorly installed - compressed batts, gaps at top plates, missing air sealing. Replacement makes sense when the product itself has failed: settled blown-in below labeled R-value, delaminated vapor retarder, or foam shrinkage. Our audit gives you the numbers to decide, with line-item pricing for both paths. Call (831) 534-3206 and we’ll walk through your written options.
We use OEM CertainTeed when it’s the right product for the assembly and available without unreasonable lead time. When CertainTeed’s current formulation has known issues - early CertaSpray shrinkage, for example - we specify quality aftermarket alternatives and explain why in your written scope. We don’t profit from brand loyalty; we profit from assemblies that perform.
A written report with your blower-door number, infrared images with annotations, a photo record of every finding, and a line-item scope with price if you want us to do the work. No PDF generated from checkbox software - real photos, real numbers, real recommendations. Under Haven Standard: Have it in writing.
