Most attic cleanouts with CertainTeed insulation removal run between $2,400 and $4,800, depending on contamination level and whether the original install included CertainTeed’s blown fiberglass or batt products.

How CertainTeed Products Fail - and How We Fix Them

  • CertainTeed InsulSafe SP blown fiberglass packs down unevenly after rodent tunneling. The product is designed for loose-fill density at R-38, but rats and mice compress runways through it, creating cold channels across the attic deck. We remove the contaminated SP, seal the bypasses first, then replace with fresh material at verified depth using depth rods. The certificate tells you what you actually got.
  • CertainTeed SpeedyR batt insulation in kneewalls and floor joists absorbs urine and loses its binder. The formaldehyde-free binder breaks down under ammonia exposure, and the batts sag away from the subfloor. In El Monte’s summer heat, this accelerates. We bag out the degraded SpeedyR, HEPA-vacuum the framing, apply an enzymatic treatment, and reinstall only after rodent exclusion is complete.
  • CertainTeed Optima loose-fill in older El Monte ranch homes settles below labeled R-value when disturbed by nesting. Roof rats from the Rio Hondo wash corridor pull Optima into nest piles, leaving bare spots near eaves. We find these pockets during our initial photo survey, remove the contaminated material, and restore full coverage with documented depth verification.
  • CertainTeed MemBrain smart vapor retarder, when present, tears during rodent activity and loses its variable permeance function. The polyamide film is effective in our mixed-humidity climate only when intact. We inspect for breaches during every cleanout, replace compromised sections with matching material, and verify continuity at seams.
  • CertainTeed TrueComfort batt insulation in bonus-room ceilings above garages compresses from rodent paths and traffic. The recycled-content batt loses loft permanently once crushed. We see this often in El Monte’s 1960s split-levels near Lower Azusa Road. Removal, decontamination, and replacement with fresh TrueComfort at proper compression resistance is the only fix that restores the original thermal boundary.

Our CertainTeed Attic Cleaning & Rodent Proofing Process

Our CertainTeed Attic Cleaning & Rodent Proofing Process
  1. 1
    Written price and scope before arrival. We review your photos or visit in person, identify the CertainTeed product line if possible, and deliver a flat price with no work starting until you have it in writing.
  2. 2
    Containment and negative-air setup. The attic access is sealed with plastic sheeting; we run HEPA-filtered negative air to keep dust and particulate out of living spaces. This matters more with CertainTeed fiberglass than with some competing products because of the fine fiber diameter.
  3. 3
    Insulation removal and bag-out. We use commercial gas-powered vacuums with 6-mil bagging, sorting CertainTeed material by type for proper disposal. We note the original install depth and any compression patterns for the final report.
  4. 4
    Rodent proofing and exclusion. Every penetration, vent, and gap larger than one-quarter inch is sealed with galvanized steel mesh, copper wool, or concrete repair as appropriate. We focus on eave returns, plumbing chases, and the top plates where CertainTeed insulation was blown without prior air sealing.
  5. 5
    Sanitizing and deodorizing. Enzymatic treatment breaks down organic matter; oxidizing fog addresses residual odor in sheathing and framing. We do not reinstall insulation until surfaces read safe on our ATP meter.
  6. 6
    Replacement, verification, and documentation. New insulation goes in only after exclusion is complete. We verify depth with rods, provide R-value certification, and leave you with a Documented Photo Record and the 365-Day Done Right Promise in writing.
