This page is for Hayward homeowners who own a home insulated with Owens Corning products, typically Pink Fiberglas batts, ProPink blown-in fiberglass, or AttiCat blown-in system material, and need the attic cleaned out and sealed against rodents. Walt Brenner has been doing this work in Hayward since 2000, and we’ve seen just about every failure mode an attic can throw at us.

How Owens Corning Products Fail - and How We Fix Them

• AttiCat blown-in fiberglass compresses under rodent traffic. Rats and mice create runways through blown-in insulation, packing it down to a fraction of its original R-value. In Hayward homes we regularly see AttiCat material matted down to R-19 or worse in high-traffic areas even when it was installed at R-38. We remove the contaminated material, sanitize the attic deck, and reinstall fresh Owens Corning blown-in insulation at the original depth.
• ProPink batts make ideal nesting material. Fiberglass batts get shredded and dragged into soffit corners, wall cavities, and around duct collars. We find nests packed into ProPink batts behind knee walls in older Hayward ranch homes near the Japanese Gardens. The fix is full contaminated batt removal, exclusion sealing, and new batts installed with proper ventilation clearance.
• Vapor barriers trap rodent urine odors. Owens Corning batt products often ship with kraft paper facing, which works fine until rodents soak it with urine. Paper facing absorbs moisture and holds odor far longer than unfaced fiberglass. We strip all faced material during decontamination because you cannot sanitize kraft paper, and we reinstall unfaced batts or blown-in material instead.
• Rodents chew through fiberglass but avoid spray foam. Mice and rats tunnel through fiberglass insulation of any brand, Owens Corning included. Hayward attics with AttiCat blown-in material are especially vulnerable because there’s nothing structurally discouraging burrowing. After cleaning, we seal penetrations with rodent-proof materials and can apply Owens Corning or Demilec spray foam at vulnerable entry points, which rodents do not chew through the way they do fiberglass.
• Owens Corning insulation hides roof leaks until they’re severe. Blown-in fiberglass absorbs moisture and masks the telltale stains you’d spot on a bare attic floor. By the time a Hayward homeowner notices, there’s often a mold issue in the insulation itself. During every Owens Corning attic cleaning we inspect for moisture damage and flag any roof leak we find so you’re not paying for a clean attic that’s wet again in six months.

Our Owens Corning Attic Cleaning & Rodent Proofing Process

Here’s how a typical Owens Corning attic job goes when you call Walt’s Insulation:

1. 1
   We answer live. No voicemail, no call center. You’ll talk to someone at (510) 871-9022 who can schedule a Hayward attic inspection, often same week.
2. 2
   We inspect the entire attic. Walt or one of our background-checked, uniformed technicians checks insulation depth, rodent entry points, droppings, nesting, chewed wiring, and duct condition. We photograph everything so you see what we see.
3. 3
   We quote the actual job. Upfront pricing, no vague ranges. You’ll know exactly what’s included: removal tonnage, sanitizing approach, exclusion sealing locations, and replacement insulation type. We’ll also tell you if anything does NOT need doing, which is rarer than it should be in this trade.
4. 4
   We remove and sanitize. Commercial HEPA vacs pull out contaminated Owens Corning material. We treat the attic deck and framing with an antimicrobial sanitizer and deodorizer that actually neutralizes rodent waste, not just masks it.
5. 5
   We seal entry points. Rodent proofing means closing every gap larger than a quarter inch. We use steel mesh, metal flashing, sealants, and spray foam at roof junctions, soffit gaps, pipe penetrations, and any other opening we find. If we don’t seal it, the rodents come back and the cleaning was a waste of your money.
6. 6
   We reinstall insulation correctly. Fresh Owens Corning AttiCat blown-in fiberglass or ProPink batts, installed to the R-value appropriate for Hayward’s climate. We leave the attic cleaner than we found it and back every bit of work with our lifetime Done Right Promise.

What Owens Corning Attic Cleaning & Rodent Proofing Costs in Hayward

Straight numbers, because you deserve them. Attic cleaning alone, including contaminated Owens Corning insulation removal and sanitizing, typically runs $1,200 to $2,400 for a standard 1,200 to 2,000 square foot Hayward home. Full rodent proofing and exclusion sealing adds $800 to $1,800 depending on how many entry points we find and how accessible they are. New Owens Corning blown-in insulation after cleanup runs $1,500 to $3,500 depending on depth and square footage.

What moves the price? How long the rodents have been active, whether there’s water damage mixed in, attic accessibility, and whether ducts need repair or replacement. Every estimate is upfront and itemized. We offer a free second opinion on any written estimate you’ve received, no trip charge inside our service county, $40 off any repair over $200, and a permanent 10% discount for seniors and veterans.
