GreenFiber Attic Cleaning & Rodent Proofing Nationwide

GreenFiber Attic Cleaning & Rodent Proofing in Palo Alto: What to Know First

We provide independent GreenFiber attic cleaning and rodent proofing in Palo Alto, typically completing most jobs in one to two days with a written price delivered before any work starts. Most GreenFiber attic cleanouts and rodent exclusion jobs in Palo Alto run between $2,800 and $6,500 depending on contamination level, accessibility, and whether the cellulose insulation requires full removal or localized treatment. This page is for homeowners who already have GreenFiber cellulose in their attic and have found droppings, nesting material, compressed insulation trails, or the ammonia-heavy smell that indicates active rodent occupation.

How GreenFiber Products Fail - and How We Fix Them

• GreenFiber AllBor Borate-Treated Cellulose - moisture wicking and compaction. The borate fire retardant in AllBor is hygroscopic, meaning it draws moisture from humid attic air. In Palo Alto’s marine-influenced climate, especially in older ranch homes near Midtown with bathroom vents dumping into the attic, we’ve seen AllBor pack down to half its original depth within eight to ten years. Compacted cellulose loses R-value and creates the dense, tunnel-like pathways rodents prefer for nesting. We remove the compacted material, repair the moisture source, and reinstall only after air sealing is complete.
• GreenFiber Sanctuary - settled dust and allergen release during disturbance. Sanctuary’s fine-fiber structure settles into a dense mat that, once contaminated by rodent urine and feces, releases particulates aggressively when disturbed. Our crew uses HEPA-contained removal with negative air pressure, not standard vacuum equipment, to prevent cross-contamination into the living space. We’ve handled Sanctuary jobs in Palo Alto where the homeowners developed respiratory symptoms only after a previous contractor stirred the material without containment.
• GreenFiber Cocoon - blown-in-wall product mistakenly installed in attics. Cocoon is designed for dense-pack wall cavities, not loose-fill attic application. When we find it in Palo Alto attics, usually from owner-installed or handyman jobs, it’s settled to an uneven density that rodents exploit for burrowing. The fix is complete removal and replacement with proper loose-fill cellulose or alternative insulation after sealing.
• GreenFiber Loose Fill - top-plate gaps exposed by rodent tunneling. Standard GreenFiber loose fill shifts over time, especially where rodents have carved runways. Those runways almost always follow unsealed top plates, the horizontal framing members where interior walls meet the ceiling deck. We map every runway back to its air leak, seal it with fire-rated caulk or foam, then restore insulation. Without this step, new insulation just gets tunneled again.
• GreenFiber with vapor barrier failure - poly sheeting degradation. In Palo Alto homes built between 1950 and 1980, we regularly find GreenFiber installed over original kraft-paper or poly vapor barriers that have shredded or detached. Rodents nest between the barrier and the cellulose, creating a double-contamination zone. We remove both layers, sanitize the deck, and install a new vapor barrier only where the building science calls for it, which in Palo Alto’s mild climate is less often than contractors assume.

Our GreenFiber Attic Cleaning & Rodent Proofing Process

1. 1
   Inspection with photo documentation. We photograph contamination extent, insulation condition, and every penetration point. You get these photos in your written scope.
2. 2
   Blower-door test if air sealing is in scope. The CFM50 reading shows how much conditioned air escapes through the attic plane. We don’t guess at leak volume.
3. 3
   HEPA-contained removal and sanitization. GreenFiber cellulose, once rodent-contaminated, requires full removal per EPA guidelines. We use contained extraction, then apply enzyme-based decontamination to the deck and framing.
4. 4
   Air sealing and rodent exclusion. Every top plate, can light, plumbing penetration, and vent gap gets sealed. Exterior entry points are blocked with steel mesh, copper wool, or concrete repair as appropriate. Seal the leaks first. The insulation has nowhere to work if the air is moving around it.
5. 5
   Insulation restoration and final test. We reinstall with GreenFiber or an alternative you choose, then run a post-work blower-door test if scoped. You receive the before-and-after CFM50 numbers, the photo record, and the written warranty.

What GreenFiber Attic Cleaning & Rodent Proofing Costs in Palo Alto

What moves the price: attic square footage, rafter height and accessibility, whether the HVAC handler is in the attic (requires extra containment), and the extent of deck replacement needed from urine saturation. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly. Every estimate is flat-priced in writing before work starts, no exceptions. Call (650) 352-3577 for your specific number.
