How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes solid insulation, but no product survives everything a Sunnyvale attic throws at it. Rodents, roof leaks, and decades of temperature swings take their toll. Here’s what we see most often on CertainTeed jobs in Sunnyvale homes:
- CertainTeed InsulSafe blown-in fiberglass settling and compaction. InsulSafe is a great product when it’s installed right, but in older Sunnyvale ranch houses near Murphy Avenue, we regularly find it compressed from years of foot traffic from cable installers, HVAC techs, and previous owners using the attic as storage. Compression cuts R-value dramatically, and vacuum removal plus fresh install is the only real fix.
- CertainTeed batt insulation with rodent contamination. CertainTeed’s fiberglass batts – we see the R-30 and R-38 lines most often in Sunnyvale – hold up structurally, but rats and squirrels burrow through them and leave waste throughout. You can’t clean contaminated batts. We remove everything, sanitize the attic deck, and replace with fresh material.
- Moisture-wicked CertainTeed batts from roof leaks. Sunnyvale’s wet winters expose small roof leaks that go unnoticed until insulation shows staining. Wet CertainTeed fiberglass loses R-value fast and starts growing mold. We identify the leak source before replacing anything, because new insulation in a still-leaking attic is wasted money.
- CertainTeed drywall and sheathing products left from remodel jobs. Some Sunnyvale homeowners have CertainTeed gypsum board from additions or remodels. When we’re doing removal work nearby, we’ll spot and remove damaged sections that were left behind by previous contractors, especially in older homes where patched drywall didn’t get proper insulation behind it.
- Aged CertainTeed vapor barriers and facing failures. Kraft-faced CertainTeed batts installed decades ago often have torn or degraded facing. The fiberglass underneath may look okay, but without an intact facing, moisture moves through and reduces performance. We remove and replace with properly faced product suited to Sunnyvale’s climate zone.

You get an upfront written quote. We tell you exactly what removal and replacement will cost, what material we recommend, and why. If you have another written estimate, bring it and we’ll give you a free second opinion.

Why Sunnyvale Homeowners Call Walt’s Insulation for CertainTeed Work
We’ve been doing this in Sunnyvale since 2000. We’re the one down the road, not a call center with an 800 number. When you call about CertainTeed insulation removal, you’re talking to someone who knows exactly what InsulSafe looks like after 20 years in a Sunnyvale attic, and who can tell you whether replacement is genuinely necessary or whether spot-fixing will do.
Our techs are background-checked and uniformed, so you know who’s walking into your home. We work with CertainTeed for removal and replacement, and we also service Reflectix and carry other manufacturers including Owens Corning, Rockwool, Icynene, Johns Manville, Demilec, Knauf, and GreenFiber, so the recommendation you get is the right product for your house, not whatever we happen to stock. Every job is covered by the Done Right Promise for life, because as Walt puts it: good insulation should be invisible, you only notice it when it’s missing.
FAQs
Most standard attics take one full day for removal and replacement. Larger attics or contaminated jobs run two days. We schedule based on your timeline and give you a clear time window before we start. Call (669) 215-4805 for a same-day or next-day assessment, no trip charge in our service county.
CertainTeed warranties cover manufacturing defects in the product itself, not installation circumstances. Insulation that’s been contaminated, compressed, or water-damaged is generally outside warranty scope regardless. We can photograph and document your existing material before removal if you want to pursue a warranty claim, but most Sunnyvale removal jobs are due to conditions no manufacturer covers. Call us at (669) 215-4805 and we’ll help you assess warranty options honestly.
If your existing CertainTeed insulation is dry, uncontaminated, and just under-performing, adding new material on top is often the cheaper route and works fine. If it’s wet, rodent-damaged, compressed, or moldy, you’re wasting money putting fresh product over a bad foundation. We’ll inspect and tell you straight which situation you have, and our free second opinion on any written estimate means you don’t have to take our word for it.
Look for uneven attic temperatures, cold spots in rooms below, damp or stained insulation when you peek up there, mouse or rat droppings, or a musty smell when you open the attic hatch. In Sunnyvale’s older ranch-style homes, we also find insulation that’s been walked on and compressed over decades of use. If you’re seeing any of these, call (669) 215-4805 and we’ll assess it in person.
Yes. We remove and replace Reflectix, Owens Corning, Johns Manville, Knauf, Rockwool, Icynene, Demilec, and GreenFiber products regularly across Sunnyvale. The removal process is largely the same, but material recommendations vary by home and climate zone, and we’ll tell you exactly what works best for your specific house.
