How Owens Corning Products Fail - and How We Fix Them

We’ve pulled Owens Corning insulation out of hundreds of Anaheim attics since 2000. Some of it was installed last decade, some of it dates back to the Nixon administration. Here’s what we actually see in this city, not what a product brochure tells you:

• Owens Corning fiberglass batts from the 1970s and 80s with failing kraft-paper facing. In older Anaheim neighborhoods like the Colony and West Anaheim, the paper vapor barrier tears, sags, or disintegrates. Once that facing goes, the batts slump away from the drywall and you lose the air seal. We pull the old batts, inspect the framing, and replace with fresh blown-in fiberglass or new batts depending on the cavity depth.
• Attic Cat blown-in fiberglass that has compacted to half its original R-value. Owens Corning AttiCat is a solid product, but blown-in fiberglass settles over time, especially in shallow attic spaces common in Anaheim’s mid-century tract homes. If your R-38 has settled to R-19, your AC is working harder than it should. We vacuum it out and blow in new material to the correct depth for our climate zone.
• Pink fiberglass batt insulation chewed through by rodents. Anaheim has its share of roof rats, especially in neighborhoods with mature citrus trees. Rodents tunnel through Owens Corning batts, leaving behind droppings and urine that make the insulation unsafe to leave in place. We remove the contaminated material, seal the entry points, and install fresh insulation so the problem doesn’t just come back in six months.
• Vermiculite-era attic insulation that Anaheim homeowners inherited when they bought older homes. Some pre-1990 attics in neighborhoods like Anaheim Shores and the historic district contain vermiculite that may have come from the Libby, Montana mine. Owens Corning never manufactured vermiculite, but plenty of Anaheim homes had it topped with or replaced by Owens Corning products over the decades. If vermiculite is present, we do not remove it ourselves. We refer you to a licensed abatement contractor, then handle the re-insulation once the space is cleared. That’s a safety line we don’t cross, and we’ll tell you that straight.
• Owens Corning ProPink batts installed poorly by a previous contractor. The product wasn’t the problem; the install was. Gaps around can lights, batts stuffed behind electrical boxes, missing coverage over top plates. When we remove and replace, we seal first, then insulate. R-value doesn’t mean much if air is blowing through the gaps.

Our Owens Corning Insulation Removal & Replacement Process

Here’s exactly how a removal and replacement job goes when you call Walt’s Insulation in Anaheim:

1. 1
   Call and talk to a person. You call (657) 214-8224, and Walt or one of the crew answers. We ask about your home’s age, square footage, and what you’re seeing. If you’re in our county, there’s no trip charge for the inspection.
2. 2
   Attic inspection and honest assessment. We get into the attic, measure the existing depth, identify the Owens Corning product type, check for moisture, mold, or rodent activity, and take photos so you can see what we see. You’ll get a written estimate with a real number, not a range that balloons later.
3. 3
   Removal with containment. We use commercial HEPA-filtered vacuums and containment barriers to pull the old insulation out without spreading dust and fibers through your house. Uniformed, background-checked techs do the work, and we lay down floor protection along the path from the attic access to the front door.
4. 4
   Sealing before insulation. Before we put anything back, we air-seal the top plates, wire penetrations, can light housings, and any plumbing stacks. This is the step a lot of outfits skip because it takes time. It’s also the step that makes the biggest difference in your energy bills.
5. 5
   Fresh insulation, correct depth. Whether we’re installing Owens Corning again or you’ve decided on Rockwool or GreenFiber based on our recommendation, we install to the right R-value for Anaheim’s climate zone, which is R-30 to R-38 in most attics.
6. 6
   Final walkthrough and our guarantee. We show you the finished attic, confirm the depth with a measuring stick, and leave the space cleaner than we found it. Every job is backed by the Done Right Promise. If it’s not done right, we make it right. No fine print, no runaround.

What Owens Corning Insulation Removal & Replacement Costs in Anaheim

Here’s what you can expect to pay in Anaheim based on the jobs we do most often. These are straight numbers from our work in this city in 2025 and 2026:

• Full attic insulation removal and re-insulation (1,200-1,500 sq ft attic): $2,400 to $4,200, depending on access, existing depth, and the new material you choose.
• Contaminated insulation removal due to rodent activity, plus re-insulation: $2,800 to $4,800, because removal and disposal costs run higher and we seal entry points as part of the job.
• Removal only, no re-insulation: $1,200 to $2,000. Some homeowners want the space cleared for a remodel or rewiring before insulation goes back in.
• Partial removal and top-off: $900 to $1,800, where sections of the attic are fine and only one area needs removal and fresh material.

What moves the price: attic access (pull-down stairs vs. a tight hatch), how much material is up there, whether it’s contaminated, and the type of new insulation you choose. Blown-in fiberglass is the most common choice in Anaheim homes. Call (657) 214-8224 for an exact quote. Estimates are free and there’s no trip charge inside the county.

Why Anaheim Homeowners Call Walt’s Insulation for Owens Corning Work

We’ve been doing this since 2000, and our shop is the one down the road, not an 800 number. Walt Brenner started this business after learning the trade hands-on at St. Philip’s College in San Antonio, and he’s been working Anaheim attics long enough to know that every house has a story. The crew has pulled Owens Corning out of homes near the Platinum Triangle, in the ranch-style neighborhoods off Lincoln Avenue, and everywhere in between. We’re an independent Owens Corning service provider, which means we tell you the truth about what’s worth keeping and what isn’t. If a section of your attic is still in good shape, we’ll tell you. If it’s shot, we’ll show you photos. And we work with other quality brands too, including Rockwool, Johns Manville, Knauf, and CertainTeed, along with Reflectix for radiant barrier applications. We do the job right the first time, because we’re the ones who have to stand behind it.
