Owens Corning Attic Cleaning & Rodent Proofing in Los Angeles: What to Know First
We provide independent Owens Corning attic cleaning and rodent proofing in Los Angeles, with most jobs completed same-day and a written price delivered before any work starts. Typical turnaround runs 4 to 6 hours for a standard attic cleanout, sanitizing, and exclusion seal on a 1,200 to 2,000 square foot home. We’re not affiliated with or authorized by Owens Corning - we work on their materials as an independent service provider, which means we source OEM and quality aftermarket parts based on what the job actually needs, not what a brand program requires.
This page is for Los Angeles homeowners who have Owens Corning insulation, radiant barriers, or attic components and need rodent damage addressed, contamination removed, or the space restored to a clean, sealed condition. Call (628) 226-1097 for a free estimate with a written scope.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles unevenly after rodent tunneling. The PINK Fiberglas Insulation line, especially the R-30 and R-38 batts blown through the AttiCat system, compacts into runways where rats and mice travel repeatedly. We remove the contaminated material entirely - never leave it layered over droppings - then seal penetration points with galvanized steel mesh and foam before reinstalling to the original R-value.
- Owens Corning Raft-R-Mate baffles collapse or detach when gnawed, blocking soffit intake. The rigid foam baffles are lightweight and effective for ventilation, but rodents chew through the leading edge and the staples pull from moisture-weakened roof decks. We replace with metal-reinforced baffles or custom-cut aluminum where the soffit chase runs long, then verify airflow with a smoke pencil.
- Owens Corning ProCat loose-fill in unsealed attics becomes a nesting substrate. When top plates and can-light penetrations are open, ProCat settles around warm air leaks and rodents burrow into it for thermal cover. Our fix: remove the contaminated ProCat, run a blower-door test to locate every leakage point, seal with fire-rated caulk and metal flashing, then blow new material to a measured depth.
- Owens Corning Foamular rigid board at knee walls gets shredded for nesting material. In Los Angeles ranch-style homes with unvented knee walls - common in the Leimert Park corridor and similar neighborhoods - Foamular XPS boards become target chewing. We replace with rodent-resistant Rockwool Comfortboard or protected assemblies, depending on the moisture load and accessibility.
- Owens Corning SOFFIT VENT products clog with guano and nesting debris. The plastic and aluminum vent strips, particularly on older installations with the 2-inch slot design, pack solid with organic material. We pull the vents, clean the channels, install stainless-steel hardware cloth behind the opening, and replace with wider-slot modern product where the fascia depth allows.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
- 1
Written price and scope before arrival. We send a flat price based on attic square footage, contamination level, and access difficulty. No work starts without a signed scope.
- 2
Blower-door test and photo documentation. We pressurize the house to measure air leakage through the attic floor - the CFM50 reading goes on your record before anyone enters the attic.
- 3
Contaminated material removal and HEPA cleanup. All Owens Corning product affected by droppings, urine, or nesting comes out. We HEPA-vacuum the deck, treat with an enzyme-based sanitizer, and dispose per California hazardous waste guidelines.
- 4
Rodent proofing and exclusion. Every penetration larger than 1/4 inch gets sealed: steel mesh for gnaw points, fire-rated foam for wire and pipe chases, metal flashing for chimney and vent gaps. Seal the holes first. Then measure the R-value. In that order.
- 5
Component replacement and insulation reinstall. We reinstall Owens Corning or compatible materials to the depth specified on your written scope, using OEM when the warranty is active and quality aftermarket when it saves money without sacrificing performance.
- 6
Final blower-door test and documented handoff. You get the after-pressurization number, installed R-value confirmation, product data sheets, and photos of every sealed point. Under Haven Standard: if the after number doesn’t beat the before, we find the leak.

AfterWhat Owens Corning Attic Cleaning & Rodent Proofing Costs in Los Angeles
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Attic cleanout and sanitizing only | $1,400 - $2,600 | Square footage, contamination depth, deck condition |
| Cleanout + rodent exclusion (no insulation replace) | $2,200 - $3,800 | Number of penetrations, roof pitch, access difficulty |
| Full restoration: cleanout, exclusion, Owens Corning reinstall | $4,500 - $7,200 | R-value target, attic floor area, blower-door improvement required |
| Severe contamination: hazmat-level guano removal | $3,000 - $5,500 | Histoplasmosis risk assessment, PPE level, disposal fees |
These are Los Angeles market ranges for 2024-2025 labor and material costs. A two-story home in the hills with a 12/12 pitch and a 1,200 square foot attic at R-38 runs differently than a single-story Valley ranch with walk-up access. We also service Reflectix radiant barrier systems when those are part of the assembly. Call (628) 226-1097 - estimates are free, and the price we write is the price you pay.

FAQs
No - professional cleaning and rodent proofing does not void Owens Corning’s product warranty, though damage caused by rodents or improper reinstallation may not be covered. We document original product labels and installation depth so any future warranty claim has the paperwork it needs. Call (628) 226-1097 if you want us to photograph your existing install for the record.
We source both. OEM Owens Corning batts, loose-fill, and accessories are available when the warranty is active or the homeowner requests them. For rodent-proofing hardware and replacement baffles, we often use quality aftermarket equivalents that meet the same thermal and fire ratings at lower cost - and we list both options on your written scope so you choose.
Replacement is usually the better value once contamination exceeds 15 to 20 percent of the attic floor or urine has saturated the fiberglass. Surface-cleaning saves money upfront but leaves odor and allergen sources that degrade air quality. We give you both numbers on the written estimate so you can compare total cost, not just today’s invoice.
Same-day or next-day for active infestations, depending on your neighborhood and crew routing. We answer calls live 24/7 and can often have a technician to your Los Angeles home within hours if gnawing or entry points are visible. Call (628) 226-1097 - we’ll confirm the arrival window while you’re on the line.
Yes. Many Los Angeles homes have Reflectix radiant barrier stapled to rafters above or below Owens Corning insulation, and rodents damage both layers. We remove, clean, and reinstall Reflectix as part of the restoration scope, or replace it if the tear pattern is too extensive. The written price covers whichever assembly you have.
