This page is for Mountain View homeowners who found Knauf insulation in their attic, suspect rodent damage, or need decontamination after an infestation. We also service Reflectix and other brands, but this page covers what we know about Knauf specifically.
How Knauf Products Fail - and How We Fix Them
- Knauf EcoBatt with ECOSE Technology - binder breakdown in attics over 140°F. The plant-based ECOSE binder softens in Mountain View’s south-facing attics during summer heat spikes, causing the batts to slump off top plates and expose gaps where rodents travel. We remove the degraded batts, sanitize the deck, and reinstall with proper mechanical fastening before blowing in new material.
- Knauf Jet Stream ULTRA blown-in fiberglass - compaction from rodent nesting. This high-loose-fill product packs down where rats and mice tunnel, creating dense cold spots that read 8-12°F lower on thermal imaging. We extract the compacted material, treat the substrate, and replace it with fresh blown-in at the original R-value specification.
- Knauf Insulation Board - edge gaps from improper original cutting. Rigid board installed around attic hatches and kneewalls often leaves 1/4-inch to 1/2-inch perimeter gaps, which become rodent superhighways. We pull the boards, seal the framing with acrylic latex caulk and steel mesh, then reinstall with zero-clearance cuts.
- Knauf Ecoseal - air-seal failure at plumbing and electrical penetrations. This water-based elastomeric sealant can crack after 5-7 years in Mountain View’s dry-season attic cycles, reopening entry points. We remove failed Ecoseal, apply fresh sealant where appropriate, and reinforce high-traffic areas with galvanized steel flashing.
- Knauf blow-in blanket system (BIBS) - netting sag from rodent weight. The polypropylene netting supporting BIBS insulation tears when rodents nest above it, dumping loose fill into the floor cavity below. We strip the compromised netting, decontaminate, install new support mesh rated for pest resistance, and refill to spec.
Our Knauf Attic Cleaning & Rodent Proofing Process
- 1
Attic assessment with photo documentation. We photograph every Knauf product line present, note contamination extent, and identify active and historical rodent entry points. You get these photos before we quote.
- 2
Written price and scope. We specify which Knauf materials stay, which get removed, and what replaces them. No work starts without your signed approval.
- 3
Contaminated material removal and HEPA extraction. We bag degraded Knauf insulation, vacuum fecal matter and nesting debris with sealed HEPA equipment, and dispose per Santa Clara County solid waste requirements.
- 4
Sanitizing and decontamination. We apply enzyme-based treatment to neutralize rodent pheromones that attract new pests, then treat for bacteria and parasites per CDC guidance.
- 5
Rodent proofing and exclusion. We seal all entry points with steel mesh, concrete patch, or copper wool depending on substrate, and install vent guards where roof rats commonly breach in Mountain View’s older neighborhoods like Rex Manor.
- 6
Reinsulation and final documentation. We reinstall Knauf or alternative product to match or exceed original R-value, then deliver your Documented Photo Record showing before, during, and after conditions.

| Job Type | Typical Range | What Moves the Price |
|---|---|---|

These are real numbers for Mountain View homes we’ve worked, not teaser rates. Final price depends on attic square footage, contamination depth, and whether we find compromised ductwork or chewed wiring that needs coordination with your electrician. We provide a Free Second Opinion on any written estimate you’ve already received. Call (669) 259-0406 for your written price.
Why Mountain View Homeowners Call Topside Attic Insulation Mountain View for Knauf Work
We’ve been in Mountain View attics since 2016, and we’ve learned that Knauf’s ECOSE binder behaves differently in our climate than the manufacturer spec sheets suggest. Wes Okafor, our owner, spent two decades on Peninsula insulation jobs and keeps a notepad in the truck with what he found in each attic. The next person up there deserves an honest picture.
Our 365-Day Done Right Promise applies to every Knauf job. If the rodents return through our exclusion work, we come back and fix it. We also service Reflectix and other brands, so we’re not locked into any single manufacturer’s product line. Calls are answered by a live person 24/7, and our technicians are background-checked and uniformed. Seal the leaks first. The insulation has nowhere to go if the air does.
FAQs
Knauf’s product warranty covers manufacturing defects, not installation or subsequent damage from rodents or water. As an independent Knauf service provider, we document the condition of your insulation before we touch it so there’s a clear record if a defect claim ever arises. Call (669) 259-0406 if you want us to photograph and catalog your Knauf products before removal.
We source Knauf EcoBatt, Jet Stream, and board products through standard distribution channels. For some older Knauf formulations no longer in production, we specify equivalent aftermarket material with matching thermal performance and fire rating. We tell you which we’re proposing before you sign the scope.
Restoration is usually 30-40% less than full removal and replacement if the Knauf insulation is less than 10 years old and the contamination is confined to surface layers. If rodents have compacted blown-in fill throughout or urine has saturated batt insulation to the deck, full replacement is the only sanitary option. We assess this during your free estimate and give you both numbers.
Most Knauf attic cleanouts in Mountain View start within 3-5 business days of estimate approval. Emergency situations, such as active rodent infestations with HVAC contamination, can sometimes be scheduled within 48 hours. Call (669) 259-0406 to check current availability.
We focus on exclusion, decontamination, and insulation restoration. For active infestations, we coordinate with licensed pest control operators in Mountain View who handle trapping and baiting, then we come in after clearance to clean and seal. This sequencing protects our technicians and ensures your Knauf insulation replacement isn’t immediately recontaminated.
