This page is for Irvine homeowners who specifically have CertainTeed materials in their walls, attics, or crawl spaces and want to know whether those products are still doing their job. If your CertainTeed fiberglass batts were installed in the 1990s or early 2000s, or your CertainTeed MemBrain smart vapor retarder was put in during an Irvine remodel, you need an audit that understands how these specific products age in coastal Southern California conditions. Let’s get into what that actually looks like.
How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes solid insulation products, but no material lasts forever and Irvine’s specific climate exposes weaknesses that other regions never see. Here are the failure modes we find most often on CertainTeed jobs in Irvine:
- CertainTeed InsulSafe SP fiberglass blown-in settling in Woodbridge attics. InsulSafe SP is a quality blown-in fiberglass, but in Irvine homes built before 2000, we regularly find it has settled from its original R-30 depth down to R-19 or worse, especially around recessed can lights and attic hatches. The fix is an energy audit that identifies the settled zones with thermal imaging, then a targeted top-off to restore design R-value. In Woodbridge specifically, where many homes still have the original 1980s insulation, this is one of the most common CertainTeed failures we document.
- CertainTeed DryRight fiberglass batts losing friction fit in wall cavities. DryRight batts are designed to resist moisture, but in Irvine’s dry-wall construction with slight settling over decades, the batts can slip within wall cavities and leave gaps at the top plate. We see this constantly during wall insulation inspections, especially on interior walls adjacent to unconditioned garage spaces. The audit catches it with an infrared camera scan; the fix is either cavity injection or careful re-fitting of existing batts.
- CertainTeed MemBrain vapor retarder installed backward during DIY or handyman remodels. MemBrain is a smart vapor retarder, meaning it changes permeability based on humidity. But it only works if the printed side faces the right direction. In Irvine remodels we audit, we find it installed upside down more often than not, which traps moisture inside wall assemblies during our coastal humidity swings. Our audit identifies this during the thermal imaging pass, and correcting it is usually a straightforward fix that prevents mold and framing rot.
- CertainTeed Thermafiber mineral wool compressed behind electrical boxes and plumbing chases. Thermafiber is an excellent product for fire resistance and sound control, but it has almost no compressive recovery. When an Irvine electrician or plumber pushes it aside to do work and then tucks it back in, those compressed areas lose most of their R-value. A duct leakage test and thermal scan during the audit reveals these dead zones, and we restore them with fresh mineral wool or a compatible blown-in product.
- CertainTeed CertaWrap house wrap failing at taped seams on Irvine stucco homes. CertaWrap does its job when seams are taped correctly with the right tape. But on Irvine stucco exteriors, especially homes near the coast where salt air and UV take a toll, we find seam tape peeling back after 10 to 15 years. That means air infiltration behind the stucco, which drives up cooling costs all summer. The audit’s blower door test quantifies the leakage; fixing it properly requires opening up the affected areas and re-taping with a compatible seam tape before the stucco repair.
These are CertainTeed-specific failure modes, not generic insulation problems. That’s the difference between an audit from a general contractor and an audit from a team that’s been working with these exact materials in Irvine for over 15 years. Neil Ashford, our owner, has kept an eye on how CertainTeed products behave in Southern California since he first learned the trade at Los Angeles Trade-Technical College, and he makes sure every audit report we hand over names the specific product, the specific failure, and the specific fix.
Our CertainTeed Home Energy Audit Process
Here’s what happens when you call us for a CertainTeed home energy audit in Irvine:
- 1
Call and schedule. You call (949) 832-7835 and talk to a live person. We ask about your home’s age, any CertainTeed products you know about, and the symptoms you’re experiencing. We schedule within a few days, often same week.
- 2
Walkthrough and visual inspection. Our background-checked technician walks your Irvine home with you, noting attic access, crawl space condition, visible insulation, and any signs of pest activity or moisture that affect energy performance.
- 3
Blower door test. We set up the blower door and measure total air leakage. Irvine homes built before 2000 with CertainTeed products typically test at 2,000 to 3,500 CFM50, which means substantial air sealing opportunity.
- 4
Thermal imaging and duct leakage testing. We scan walls, ceilings, and floors with an infrared camera to find gaps in CertainTeed insulation and air barrier failures. If you have a ducted HVAC system, we run a duct leakage test to quantify how much conditioned air is escaping into the attic or crawl space.
- 5
Report and recommendations. You get a written report the same day, with photos, test numbers, and a prioritized list of fixes. We price any repair or retrofit work upfront, and most jobs are completed in a single visit if you want us to proceed.
- 6
Done Right Promise. Every repair or retrofit we do for your CertainTeed home is backed by our 90-Day Done Right Promise. If it’s not right, we make it right. That’s in writing.
What CertainTeed Home Energy Audit Costs in Irvine
Our CertainTeed home energy audit pricing in Irvine breaks down like this:
- Audit-only package (blower door + thermal imaging + visual inspection): $199 to $349 depending on home size and number of zones
- Full diagnostic package (audit + duct leakage testing + written report): $349 to $495 for most Irvine single-family homes
- Targeted CertainTeed inspection (single system, like attic insulation only): $150 to $250
What moves the price: home square footage, number of stories, attic accessibility, and whether you want duct testing included. If you proceed with any repair work we recommend, we credit the audit fee toward the job. That means in many cases your audit ends up costing nothing. Estimates are always free, and you get the number before we do any work.

FAQs
No. Thermal imaging, blower door testing, and visual inspection are non-invasive and do not affect your CertainTeed product warranty in any way. In fact, documenting your insulation’s condition with a professional audit can help you if you ever need to file a warranty claim.
Most CertainTeed insulation failures we find in Irvine are repairable without full replacement. Settled InsulSafe SP can be topped off, compressed Thermafiber can be re-fluffed or replaced in isolated areas, and vapor retarder orientation can often be corrected. Full replacement is only necessary in cases of pest contamination, water damage, or severe settling. Call (949) 832-7835 and we’ll tell you honestly which path makes sense for your home.
We can typically schedule your audit within three to five business days, and the audit itself takes two to four hours. If you want repairs done immediately, most jobs are completed in a single visit. Emergency and weekend appointments are available.
Yes. Part of the audit includes identifying your existing insulation by brand and type, including whether it’s CertainTeed or another manufacturer. Many Irvine homeowners don’t know what’s in their attic or walls, and the audit is designed to answer exactly that question. Plus the energy performance questions that actually matter.
Repair is almost always cheaper, especially if the insulation is less than 15 years old and hasn’t been contaminated by pests or water. A proper audit tells you which sections are still performing well and which need attention, so you only pay for what’s actually failing. Call (949) 832-7835 for a free estimate and we’ll give you straight numbers, not a sales pitch.
