Key Takeaways

• As an independent CertainTeed service provider, we clean, sanitize, and rodent-proof attics without voiding your CertainTeed warranty.
• CertainTeed batt and blown-in insulation holds odors and contaminants differently than other brands, which changes how we clean it.
• Fullerton’s hot, dry summers bake rodent waste into insulation, making decontamination more involved than a simple vacuum-out.
• Walt’s Insulation has been crawling through Fullerton attics since 2000, and we back every rodent proofing and attic restoration job with the Done Right Promise.

How CertainTeed Products Fail - and How We Fix Them

CertainTeed makes solid insulation, but rodents don’t care about brand reputation. Here’s what we actually see in Fullerton attics and how we address each problem.

• CertainTeed InsulSafe SP blown-in fiberglass compresses under rodent traffic. Rats and squirrels create tunnels and nesting hollows through the fill, crushing the loft that gives InsulSafe SP its R-value. The compressed zones create cold spots and let heat pour through the ceiling. We remove the contaminated and compressed sections, sanitize the decking below, and re-blow fresh material to match the surrounding R-value.
• CertainTeed R-30 unfaced batts soak up urine and hold the smell. Fiberglass itself doesn’t break down, but rodent urine saturates the batt fibers and the kraft facing wicks it across the bay. Once that ammonia odor cooks in a Fullerton summer attic that easily hits 140 degrees, the smell pushes into living space every time the AC kicks on. We pull the affected batts, treat the framing with an enzyme decontaminant, and install new batts only after the exclusion work is complete.
• CertainTeed MemBrain smart vapor retarder gets chewed at the eaves. Rats love running the eave line, and MemBrain tears at corners and seams. A torn vapor retarder lets moisture migrate into the ceiling plane, which leads to drywall staining you’ll spot from the living room. On CertainTeed jobs we inspect the full vapor retarder run, cut back torn sections cleanly, and re-seal with acoustic sealant before reinstalling insulation.
• CertainTeed DryRight fiberglass panels become nesting material when rodents shred the face. We’ve found nests built almost entirely from shredded DryRight facing in Fullerton attics. The panels look fine from the access hatch, but the top side is chewed down to bare fiberglass. During cleanout we go panel by panel, flag any whose structural face has been compromised, and replace them so the insulation actually stays where it’s supposed to.
• CertainTeed duct wrap and pipe insulation get urine-coated, not just dusty. In attics where rodents have been active for more than a season, the CertainTeed fiberglass duct wrap on HVAC supply lines is often saturated with droppings and urine. Cleaning duct wrap is a losing game, so we strip it, sanitize the galvanized duct below, and re-wrap with fresh CertainTeed or equivalent material depending on what your system calls for.

Our CertainTeed Attic Cleaning & Rodent Proofing Process

We’ve been doing attic restoration in Fullerton since 2000, and Walt Brenner has personally logged more hours in these attics than he cares to count. The process works like this:

1. 1
   Walkthrough and inspection. We get into the attic and document the full picture: rodent entry points, active nesting, insulation condition, vapor retarder damage, and the specific CertainTeed products present. You get a written scope and price before we touch anything.
2. 2
   Exclusion first. Rodent proofing means sealing every entry point: gable vents, eave gaps, plumbing stack penetrations, and ridge vent gaps. We use galvanized steel mesh, hardware cloth, and sealant rated for the crawl. No exclusion means whatever we clean will be dirty again in six months.
3. 3
   Contaminated insulation removal. We pull all affected material, bag it inside the attic so no dust or droppings travel through your house, and lower bags down through a contained chute or out an exterior eave access.
4. 4
   Sanitizing and decontamination. The decking, framing, and any remaining duct surfaces get treated with an enzyme-based decontaminant that breaks down urine crystals and bacterial colonies. This is where the odor gets killed, not masked.
5. 5
   Air seal and re-insulate. While the attic is open, we seal top plates, wire penetrations, and can light housings, then re-insulate to R-38 or better using fresh CertainTeed, Owens Corning, or Johns Manville material depending on what fits your home and budget.
6. 6
   Final verification and Done Right Promise. We walk you through photos of the sealed entries and the finished attic before we pack up. If anything isn’t right, we come back and make it right. That’s the promise, and we’re the ones who have to stand behind it.

What CertainTeed Attic Cleaning & Rodent Proofing Costs in Fullerton

Here are the price ranges we quote most often on CertainTeed attic jobs in Fullerton. These are for typical single-family homes with pitched roofs and standard attic access.

• Attic cleanout and debris removal (no rodents): $900 to $1,600 for a standard 1,200 to 1,800 square foot attic.
• Full rodent decontamination with sanitizing: $1,800 to $3,200, including removal of contaminated insulation, enzyme treatment of decking and framing, and full attic cleaning.
• Exclusion and rodent proofing (sealing all entry points): $600 to $1,500 depending on how many gable ends, eave lines, and penetrations we’re sealing.
• Complete CertainTeed attic restoration (clean, sanitize, exclude, re-insulate to R-38): $3,500 to $6,500 for the typical Fullerton home.

What moves the price is square footage, how deep the contamination goes, attic access difficulty, and whether your home needs partial or full decontamination. Homes near the Fullerton Arboretum with older ranch-style construction tend to have more eave entry points than newer builds across town. Every quote is free, and we’ll hand it to you before you commit. Call (657) 216-9948 for an exact price on your attic.
