CertainTeed Insulation Removal & Replacement in Irvine: What to Know First
CertainTeed insulation removal and replacement in Irvine typically runs $1.50 to $4.50 per square foot depending on the condition of the existing material, access, and whether air sealing is part of the job. We’re an independent CertainTeed service provider (not affiliated with or authorized by CertainTeed), and most removal and replacement jobs are completed in a single visit. This page is for Irvine homeowners who own a home with CertainTeed fiberglass batts, blown-in insulation, or attic systems that have failed, been contaminated, or simply stopped doing their job.
If you’re reading this with a hot upstairs, a rodent problem in the attic, or insulation that looks like it’s been through a few decades of neglect, you’re in the right place. Call (949) 832-7835 and you’ll get a live person, 24/7. Neil Ashford and our crew have been working Irvine homes since 2011.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed InsulSafe SP Black-Dyed Fiberglass Settling: In Irvine’s dry heat, this blown-in fiberglass doesn’t degrade chemically, but it settles. After 15-20 years, you can lose 20-30% of your R-value just from compaction. Pests tunneling through it make it worse. We remove it, air-seal the attic floor, and install fresh material to current code depth.
- CertainTeed InsulSafe XC Crumbling in Tight Spaces: This high-density blown-in product holds up well in open attics, but in tight eaves or around recessed can lights, we find it compressed during original installation. Compressed fiberglass loses its air-trapping ability, which is the whole point. We remove the compressed zones and correct the installation.
- CertainTeed R-30 Kraft-Faced Batts with Failing Facing: Older CertainTeed kraft-faced batts in Irvine homes from the 1980s and 1990s often have torn or sagging paper facing. Once the facing tears, moisture can reach the fiberglass and the batt sags away from the drywall. You get a cold stripe in the ceiling. We strip the old batts and reinstall unfaced or properly faced product per California code.
- Water-Stained CertainTeed Batts After a Roof Leak: Fiberglass doesn’t grow mold readily, but the paper facing and embedded dust do. If you had a roof leak, a plumbing vent failure, or an AC condensate overflow, affected CertainTeed batts need to come out. Wet insulation is dead insulation. We remove every stained section and replace it.
- CertainTeed Blown-In Fiberglass Contaminated by Rodents: We see this constantly in older Irvine neighborhoods like Woodbridge, where attics haven’t been touched since the 1980s. Rats and mice tunnel through blown-in CertainTeed, leaving urine-soaked fiberglass and compressed nesting areas. Removal is the only real fix. We remove, sanitize, seal entry points, and blow in fresh material.
Our CertainTeed Insulation Removal & Replacement Process
- 1
We inspect the attic first. We map the existing insulation type, depth, condition, and where air is leaking. We also check for moisture, pests, and ventilation problems. No charge for the inspection.
- 2
We give you an upfront price. You know the full cost before we touch a tool. Most CertainTeed removal and replacement jobs in Irvine run ol,500 to $4,800 depending on square footage and condition.
- 3
We remove the old CertainTeed material. High-powered HEPA-filtered vacuums pull out the old fiberglass, batts, and debris. We bag it and haul it. We don’t leave a mess in your garage or yard.
- 4
We air-seal the attic floor. This is the step generalists skip. Before new insulation goes in, we seal top plates, wire penetrations, can light housings, and plumbing chases with foam and caulk. Sealing matters more than insulation in many Irvine homes.
- 5
We install the replacement insulation. Whether it’s blown-in fiberglass or fresh batts, we install to or above current California Energy Code depth. We can use CertainTeed or comparable material depending on availability and your preference.
- 6
We test and walk you through it. We verify depth with a calibrated gauge, show you before-and-after photos, and explain what we did. Your 90-Day Done Right Promise starts that day. If it’s not right, we make it right.
What CertainTeed Insulation Removal & Replacement Costs in Irvine
We price by the square foot of attic area, and every job is different. Here’s what Irvine homeowners typically see on a CertainTeed removal and replacement:
- Small attic (500-800 sq ft), no contamination: $1,200 to $2,200, single visit.
- Medium attic (800-1,500 sq ft), moderate settling or compression: $2,200 to $3,800.
- Large attic (1,500-2,500 sq ft), full removal plus air sealing: $3,800 to $6,500.
- Rodent contamination or water damage: Add $500 to $1,500 depending on severity, sanitizing, and entry-point sealing.
- Attic air sealing added to removal job: $600 to $1,200 for most Irvine homes, occasionally more if the attic is complex.
What moves the price: attic accessibility, contamination level, whether we’re hauling out heavy or wet material, and how many penetrations need sealing. We also honor three standing offers: $50 off any repair over $250, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount.

FAQs
No. CertainTeed’s warranty covers manufacturing defects in the material, not installation quality or normal aging. Removing and replacing old CertainTeed insulation does not void any remaining manufacturer warranty on the material itself. We’re an independent provider and we don’t represent CertainTeed, but a removal and replacement done by a licensed contractor is standard practice and does not trigger warranty penalties. Call (949) 832-7835 and we’ll verify any product-specific questions before we start.
Replacement is almost always cheaper in the long run when the insulation is compressed, contaminated, or older than 15 years. Repairing means adding new material on top of old problems - the old insulation still settles, still leaks air, and still hides whatever’s underneath. In Irvine, a full removal and replacement for a typical 1,200-square-foot attic runs $2,200 to $3,800 before any discounts, and you get a fresh start plus a 90-day guarantee. Call for an exact quote - estimates are free.
Most CertainTeed removal and replacement jobs are completed in a single visit, usually within one day for attics up to 1,500 square feet. Larger or heavily contaminated attics may take a second day for sanitizing and sealing. One call to (949) 832-7835 gets you on the schedule, and the live person on the line can usually confirm timing within minutes.
Yes, and you should. Rodent-contaminated insulation isn’t just dirty; it holds urine, droppings, and compressed nesting material that continues to off-gas into your home. We remove every bit of the contaminated CertainTeed material, sanitize the attic floor, seal entry points, and blow in fresh insulation. We’ve done this job hundreds of times in Irvine neighborhoods including Woodbridge. It’s not a patch job. It’s the real fix.
Plan on $1.50 to $4.50 per square foot depending on attic condition and whether air sealing is included. Simple removal of loose-fill without contamination sits at the low end. Rodent cleanup, water damage, or heavy compressed batts push toward the high end. We’ll give you a square-footage-based price before we start, and the $50-off-any-repair-over-$250 discount or 5% senior and veteran discount applies where eligible. Call (949) 832-7835 for a free estimate.
