Owens Corning Insulation Removal & Replacement in Pasadena: What to Know First
Owens Corning insulation removal and replacement in Pasadena typically costs between $1,800 and $4,500 depending on attic size and the condition of the existing material, and most jobs are completed in one to two days. We’re an independent Owens Corning service provider, which means we work on their products every week but we’re not tied to any manufacturer’s script when it comes to telling you what your house actually needs. If you’ve got Owens Corning fiberglass batts that are sagging, blown-in fiberglass that’s settled flat, or insulation that’s been chewed up by rodents, this page will tell you what’s involved in getting it out and getting the right replacement in. Call (626) 606-2964 and a live person answers, day or night.
How Owens Corning Products Fail - and How We Fix Them
We’ve pulled Owens Corning insulation out of Pasadena attics since 2000, and certain problems show up again and again. Here’s what we see most often, and what we do about it.
- Pink fiberglass batts losing their loft in older Pasadena homes. Owens Corning’s Pink Panther batts (the R-30 and R-38 lines you’ll find in homes built from the 1950s through the 1990s around Bungalow Heaven and Madison Heights) are fiberglass, and fiberglass doesn’t last forever. Once the binders break down and the batts compress under their own weight, you’re getting maybe R-19 performance out of what was sold as R-30. We remove the flattened material and replace it with fresh Owens Corning batts or blown-in fiberglass to bring the attic back to code-recommended levels.
- AtticCat blown-in fiberglass settling in Altadena and San Rafael hillside homes. Owens Corning’s AtticCat blown-in system was hugely popular in Pasadena-area new construction during the 2000s. The problem is that the blown-in fiberglass settles over time, especially in attics with uneven framing or where the insulation was installed at minimum depth to begin with. A house that started with 14 inches of AtticCat might be down to 8 or 9 inches after 15 years. That’s not a manufacturer defect; it’s physics. We remove the old material when it’s contaminated or severely compressed, and either top it off or start fresh depending on what the attic inspection shows.
- Moisture-soaked Owens Corning batts around Pasadena’s vintage roof penetrations. Homes near the Rose Bowl and along Orange Grove Boulevard deal with a particular combination: old roof flashing, occasional heavy rain, and fiberglass batts that wick moisture like a sponge. Once Owens Corning fiberglass gets wet, the R-value drops hard and it never fully recovers even after it dries. If we find wet batts during removal, we trace the leak before we put anything new in. There’s no point reinstalling insulation under a roof that’s still letting water in.
- Rodent-damaged Owens Corning insulation in foothill neighborhoods. Rats and mice love fiberglass insulation as nesting material, and Owens Corning batts are no exception. In areas like Hastings Ranch and Upper Hastings, we regularly find tunnels, droppings, and urine-soaked insulation throughout the attic. This is the most common reason Pasadena homeowners call us for full removal rather than topping off. We pull everything out, sanitize the attic deck, rodent-proof the entry points, and then install new insulation.
- Vermiculite concerns in pre-1990 attics. This isn’t specific to Owens Corning, but it comes up constantly in Pasadena’s older housing stock. Homes built before 1990 sometimes have vermiculite insulation mixed in with or sitting beneath newer fiberglass. Some vermiculite contains asbestos, and disturbing it during a removal job requires proper handling. We’ll identify it during the attic inspection and walk you through your options honestly. If testing is needed, we’ll tell you before any work begins.
Our Owens Corning Insulation Removal & Replacement Process
Every Owens Corning removal job follows the same straightforward path, whether it’s a 900-square-foot bungalow attic or a sprawling two-story in Linda Vista.
- 1
You call and talk to a person. Not a phone tree. We ask about what you’re seeing, schedule a time that works, and show up when we say we will. There’s no trip charge inside Los Angeles County.
- 2
We inspect the attic and the insulation. Walt Brenner or one of our senior techs goes into the attic, measures the existing depth, checks for moisture, rodent activity, and vermiculite, and takes photos so you can see exactly what we’re seeing.
- 3
We give you a written, upfront price. The quote covers removal, disposal, any attic prep work, and the replacement insulation installed to the right R-value for Pasadena’s climate zone. If you’ve got a written estimate from another contractor, we’ll give you a free second opinion on it.
- 4
We remove the old insulation. Commercial HEPA-filtered vacuum equipment pulls out the old material into contained bags. We don’t drag fiberglass through your house, and we protect the living space with floor coverings and sealed doorways.
- 5
We install the replacement. Depending on your home and budget, that’s fresh Owens Corning batts, Owens Corning AtticCat blown-in fiberglass, or another brand we trust like Rockwool or Johns Manville if the job calls for it. We air-seal the attic floor before installing wherever it makes sense.
- 6
We walk you through the finished job and back it with the Done Right Promise. You see the attic before we leave. If anything isn’t done right, we make it right. That’s not a 30-day warranty with fine print; it’s our lifetime workmanship guarantee, and it’s been that way since 2000.

Why Pasadena Homeowners Call Walt’s Insulation for Owens Corning Work
Plenty of contractors will remove insulation. Not many will give you the name of the person who owns the company, answer the phone at 2 a.m. when you’ve got a rodent problem, and put a lifetime guarantee in writing before the job starts. We’ve been doing insulation work in Pasadena since 2000, and we’re the one down the road, not a franchise with a rotating crew. Our techs are background-checked and uniformed, so you know exactly who’s in your attic. We install Owens Corning products regularly, but we’re not married to one brand, either. If your attic situation calls for Rockwool’s moisture resistance or a Reflectix radiant barrier under the roof deck, we’ll tell you that. We answer the phone live because your house doesn’t keep business hours, and neither do we.
FAQs
No. Owens Corning’s insulation warranties cover manufacturing defects in the product itself, not the lifespan of the installation. If the insulation is being removed because it’s contaminated, compressed, or no longer performing, the warranty doesn’t typically apply to those conditions anyway. We’re an independent Owens Corning service provider, so we always recommend checking your specific warranty documentation, but removal and replacement by a licensed contractor does not automatically void a manufacturer warranty. Call (626) 606-2964 if you want us to look at what you’ve got before you decide.
Most standard attic removal and replacement jobs are done in one to two days. Larger homes, rodent remediation, or vermiculite handling can add time. We’ll give you a firm schedule when we quote the job, and we stick to it.
Sometimes, yes. If the existing insulation is dry, pest-free, and just underperforming, topping it off with blown-in fiberglass can be a smart, budget-friendly move. But if there’s rodent contamination, moisture damage, or the old batts are blocking ventilation, adding more on top just buries the problem. We’ll tell you which path makes sense for your attic, not the one that makes us more money. Call (626) 606-2964 for a straight answer based on an actual inspection.
Absolutely. We install Owens Corning, Rockwool, Johns Manville, CertainTeed, Icynene, Demilec, Knauf, and GreenFiber. The brand decision should be based on your attic’s condition, your home’s architecture, and your budget, not on a contractor’s preferred supplier. We’ll walk you through the trade-offs in plain English.
Yes. In fact, rodent-contaminated insulation is one of the most common reasons Pasadena homeowners call us for full removal rather than a simple top-off. We remove the soiled material, sanitize the attic deck, seal entry points, and then install fresh insulation. The $40 off any repair over $200 applies to rodent proofing work too. Call (626) 606-2964 and we’ll get you on the schedule.
