How CertainTeed Products Fail - and How We Fix Them

• CertainTeed InsulSafe SP blown-in fiberglass compacts unevenly after rodent nesting. The product is designed for loose-fill depth at R-38 or R-49, but rodent tunneling creates void channels that collapse during cleanup. We remove the contaminated SP, seal bypasses with two-part foam, then reinstall to settled-depth spec with a photographic record.
• CertainTeed SpeedyR rigid board insulation at knee walls attracts burrowing. The foil-faced polyiso boards in Westminster’s older split-levels leave a gap at the stud bay that roof rats exploit for harborages. We pull the boards, sanitize the bays, install 1/4-inch galvanized hardware cloth as a mechanical barrier, then reinstall or replace with new rigid board.
• CertainTeed SoftTouch duct wrap loses its vapor barrier after rodent urine saturation. The white ASJ (all-service jacket) facing delaminates and the fiberglass underneath becomes a biohazard reservoir. We remove the wrap entirely, HEPA-vacuum the duct surface, apply antimicrobial treatment, then re-wrap with fresh jacketed insulation - never reusing compromised facing.
• CertainTeed TrueComfort batt insulation in attic floors compresses to R-11 or lower after years of rodent traffic. The product label may read R-30, but compaction and fecal loading destroy loft. We extract the batted material, which often reveals unsealed top plates and can-light penetrations that were the real thermal weak point all along. Seal first, then insulate.
• CertainTeed CertaSpray open-cell foam shows rodent gnaw patterns at protruding edges. While foam itself isn’t a food source, roof rats in Westminster’s dense neighborhoods chew exposed surfaces for dental maintenance. We trim back damaged foam, assess structural integrity, then apply a physical barrier or switch to a less accessible insulation strategy for that zone.

Our CertainTeed Attic Cleaning & Rodent Proofing Process

1. 1
   Written price before arrival. We review photos or visit in person, scope the CertainTeed product type and contamination level, and deliver a flat price with written scope. No work starts without it - Haven Standard Clause 1.
2. 2
   Containment and HEPA extraction. The crew sets negative air if needed, then removes all contaminated CertainTeed material by type: blown-in, batt, rigid, or spray foam. Each category is bagged separately for proper disposal.
3. 3
   Air sealing before anything else. Top plates, can lights, plumbing and electrical penetrations, and chimney chases are sealed with two-part foam or fire-rated caulk as code requires. “Seal the bypasses first. The R-value on the bag is only real if the air has nowhere else to go.”
4. 4
   Rodent proofing and exclusion. Entry points are mapped, opened to 1/4-inch mesh or 26-gauge sheet metal where gnawing is likely, and sealed. We focus on eave returns, roof-to-wall intersections, and pipe penetrations - the three most common Westminster access points.
5. 5
   Sanitizing and restoration. Subfloors and framing receive antimicrobial treatment. New CertainTeed or compatible insulation is installed to specified depth, with a final settled-depth photograph and, on applicable jobs, before-and-after blower-door numbers.
6. 6
   Documented Photo Record delivery. You receive the photos, the written warranty, and the 365-Day Done Right Promise in writing before we leave.

What CertainTeed Attic Cleaning & Rodent Proofing Costs in Westminster

Most attic cleanouts with rodent proofing in Westminster run between $1,800 and $4,200. Light contamination with one or two entry points and minimal insulation replacement typically lands at the lower end. Heavy rodent soiling requiring full insulation removal, extensive air sealing, and multi-point exclusion pushes toward the higher range. CertainTeed SoftTouch duct wrap replacement adds $400-$800 per system. SpeedyR rigid board reinstallation at knee walls runs $600-$1,400 depending on linear footage. We also service Reflectix radiant barrier systems if your attic has mixed brands. Every estimate is free, written, and binding - no surprises after the crew arrives. Call (562) 526-6978 to schedule.
