CertainTeed Insulation Removal & Replacement in Fullerton: What to Know First
CertainTeed insulation removal and replacement in Fullerton typically runs $1.50 to $4.00 per square foot depending on what’s up there, how much has to come out, and whether we find rodent damage or moisture once we get into the attic. Most full attic jobs are done in one to two days, and we’re an independent CertainTeed service provider, meaning we work on their products every week but we don’t answer to their corporate office. You can reach Walt’s Insulation 24/7 at (657) 216-9948.
This page is for Fullerton homeowners who have CertainTeed fiberglass batts, blown-in InsulSafe, or older CertainTeed products that have failed, gotten wet, or been torn apart by rodents.

How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes decent insulation. But nothing lasts forever in a Fullerton attic, where summer heat bakes the top of your house for months at a stretch. Here’s what we actually see when we pull CertainTeed out of attics across Fullerton.
- InsulSafe blown-in fiberglass settles and loses R-value. CertainTeed InsulSafe is a solid blown-in product, but after 15 to 20 years in Fullerton’s heat, it compacts. We regularly find attics that were rated R-38 when they were insulated and are now testing at R-24 or worse because the material has flattened. We pull the old stuff, check the air sealing underneath, and blow in fresh material to the right depth for Fullerton’s climate zone.
- Fiberglass batts that have been wet lose their structure and will never recover. CertainTeed’s fiberglass batts rely on a resin binder to hold their shape. Once roof leaks or condensation soak them, the binder breaks down and the batts slump against the drywall. We see this frequently in older Fullerton ranch homes near the Arboretum where original shake roofs leaked before being replaced. Wet fiberglass doesn’t dry out and bounce back. It comes out.
- Rodents shred CertainTeed batts faster than you’d believe. Rats and mice love tunneling through fiberglass batts. They tear the material apart for nesting and leave droppings and urine throughout the insulation. In Fullerton neighborhoods with older citrus trees, rodent pressure is constant. When we find contaminated insulation, we remove everything, sanitize the attic floor, air seal entry points, and install fresh material. We don’t leave even a quarter of the old stuff up there.
- Older CertainTeed loose-fill with settling pockets creates uneven coverage. Homes built in the 1970s through the 1990s in Fullerton often had original CertainTeed loose-fill installed by volume, not by coverage. Corners get missed, edges around the eaves stay thin, and you end up with hot spots in bedrooms and cold spots over the living room. We remove the inconsistent fill and correct the coverage with a measured re-install.
- CertainTeed MemBrain smart vapor retarders installed wrong trap moisture in Fullerton walls. MemBrain is a good product when it’s installed on the correct side of the wall assembly. But we’ve been into Fullerton homes where it was placed on the wrong side, or doubled up by a previous contractor, and the result was trapped moisture, mold, and insulation that had to come out. We fix the assembly, not just the symptom.
One more thing worth saying: a lot of insulation “issues” aren’t insulation issues at all. They’re air sealing issues. If your attic has gaps around can lights, plumbing stacks, or the attic hatch, no brand of insulation will make the room below comfortable. We check for that on every removal and replacement job, because replacing insulation without fixing the air leaks is just throwing your money into the attic.
Our CertainTeed Insulation Removal & Replacement Process
Here’s what a typical CertainTeed removal and replacement job looks like from call to cleanup, so you know what to expect when you call Walt’s Insulation in Fullerton.
- 1
You call, a person answers. Not a phone tree, not a call center. You’ll talk to someone who actually knows attics, and you’ll get a time for a free estimate.

We inspect and diagnose. We get into the attic, identify what CertainTeed product is up there, measure what’s left of its R-value, and check for moisture, rodents, mold, or air sealing failures.
- 3
You get a written quote. We show you the number before any work starts. If you have another written estimate, bring it. We’ll give you a free second opinion on it.
- 4
Removal day. We contain the work area, run a HEPA vacuum for loose-fill or bag up batts, and get everything out clean. We don’t leave old insulation bits behind in your house.
- 5
Air seal, sanitize, and prep. We seal gaps with foam, treat the attic floor if rodents were present, and get the space ready for new material.
- 6
Fresh insulation, installed correctly. Blown-in, batts, or spray foam depending on your home and your budget. Then we clean up and show you what was done.
Every step of that is backed by the Done Right Promise. If it’s not done right, we make it right. No runaround, no excuses.
What CertainTeed Insulation Removal & Replacement Costs in Fullerton
The honest answer: most Fullerton homes run between $1.50 and $4.00 per square foot for removal and replacement, and the total depends mostly on how much has to come out and what’s replacing it. A 1,500 square foot attic usually lands in the $2,200 to $6,000 range. Here’s how the common scenarios break down.
| Job Type | What It Involves | Typical Fullerton Cost |

| Batt removal only | Remove and bag fiberglass batts | $0.60 - $1.00 per sq ft |

FAQs
Adding more on top is cheaper in the short run, but if your existing CertainTeed insulation is wet, moldy, rodent-damaged, or compacted beyond saving, adding new material just buries the problem. In Fullerton, where attics bake all summer and moisture builds up in winter, compromised insulation keeps underperforming no matter how much new stuff you pile on top. We’ll tell you straight whether you can top off or need full removal. Call (657) 216-9948 and we’ll take a look for free.
Yes, in most cases we can start removal the same day or next day for full attic jobs. Small jobs, like a section of water-damaged batts, are almost always same-day. If you call early, there’s a good chance we can get a crew out that afternoon.
Most CertainTeed warranties are tied to the original installation and have long since expired by the time we’re pulling the material out. If your insulation is still under a builder’s warranty, we’ll help you understand what’s covered before we touch anything. As an independent CertainTeed service provider, we don’t have a stake in whether you file a claim or not. We just want you to get the right fix.
Signs to look for: musty smells in rooms below the attic, visible rodent droppings or trails in the insulation, rooms that won’t hold temperature even after you adjust the thermostat, and rising energy bills without a change in usage. If you see any of that, the best move is a crawl. We’ll get in there and tell you exactly what you’ve got, no charge for the estimate.
If you’ve had a roof leak, a rodent invasion, or a fire in the attic, call (657) 216-9948 right now. We answer the phone 24/7, and we’ll get a tech out to Fullerton as fast as physically possible. Emergency jobs happen. We plan for them.
