How GreenFiber Products Fail, and How We Fix Them

GreenFiber makes a solid cellulose product. But in Fullerton’s dry heat and older ranch-style attics, rodents treat it like a hotel. Here’s what we see on GreenFiber jobs and what we do about it:

• GreenFiber Sanctuary and Cocoon insulation get tunneled through by rats and mice. Cellulose is loose and soft, so rodents burrow through it far easier than through fiberglass batts or spray foam. In Fullerton homes near the Arboretum and along Chapman Avenue, we regularly find nesting cavities chewed into GreenFiber Sanctuary blown-in coverage. We remove the contaminated material, sanitize the decking, and install exclusion so they don’t come back.
• Urine and droppings saturate GreenFiber’s high recycled content and hold odor longer. GreenFiber uses up to 85% recycled paper fiber, and paper absorbs urine far more aggressively than fiberglass. That means a rat infestation in Fullerton’s summer heat turns a GreenFiber attic into an ammonia box that smells through the drywall. We remove the saturated cellulose entirely, decontaminate, and re-insulate only after the attic is clean and sealed.
• Compression and settlement in GreenFiber blown-in applications create hidden rodent paths. In Fullerton’s older homes with low-slope roofs, GreenFiber cellulose settles over time, especially if it was installed at less than the recommended depth. That settlement opens gaps along top plates and soffit junctions where rodents squeeze through. During a cleanout we get down to the decking, find those gaps, and seal them properly before any new insulation goes in.
• Rodents shred GreenFiber’s borate-treated material for nesting, but the borate doesn’t repel them. GreenFiber products are treated with borates for fire resistance and mold resistance, not for pest deterrence. Homeowners sometimes think the treatment will keep rodents out. It won’t. We say that on the phone before we even schedule the job because it saves people a second call. Rodents will happily nest in treated GreenFiber, and we have pulled enough shredded borate-treated cellulose out of Fullerton attics to prove it.
• DIY attic cleanouts of GreenFiber almost always leave contaminated insulation behind. We have followed behind more than a few weekend cleanouts where the homeowner vacuumed the top layer and left matted, urine-soaked cellulose pressed against the decking. That hidden contamination keeps the smell alive and the insects coming. We go to the wood, every time, and you can see the difference when we’re done.

Our GreenFiber Attic Cleaning & Rodent Proofing Process

This is the order we work on every GreenFiber attic job in Fullerton, and we don’t skip steps:

1. 1
   Call and walkthrough. You call (657) 216-9948, a live person answers, and we schedule a time to look at your attic. We check access, insulation depth, and rodent activity before quoting anything.
2. 2
   Inspection and honest assessment. We get into the attic, identify the GreenFiber product, map the damage, and find every entry point. If the insulation is salvageable in some areas, we tell you. If it’s not, we tell you that too, with photos and a straight explanation.
3. 3
   Containment and removal. We set up dust containment, bag and remove contaminated GreenFiber cellulose through the attic access, and haul it off. Fullerton homes with tight hallways and finished ceilings appreciate that we don’t drag debris through the living room.
4. 4
   Sanitizing and decontamination. We treat the decking and framing with a professional-grade antimicrobial sanitizer that breaks down urine residue and odor at the source. This step is the difference between a clean attic and one that still smells in August.
5. 5
   Rodent proofing and exclusion. We seal entry points at the eaves, soffit junctions, roof intersections, and any wall penetrations using materials rodents can’t chew through. We also check the attic hatch, vents, and chase ways from the garage.
6. 6
   Final check and Done Right Promise. We walk the attic with you if you want to climb up, show you the sealed entry points, and explain what we did. Every job is covered by our lifetime workmanship guarantee: if it’s not done right, we make it right, no runaround.

What GreenFiber Attic Cleaning & Rodent Proofing Costs in Fullerton

Here’s what Fullerton homeowners can expect to pay for GreenFiber attic work, based on the size of the attic and how much damage has been done:

• GreenFiber cleanout and sanitizing only (small attic, under 800 sq ft): $1,200 to $1,800
• GreenFiber cleanout with sanitizing and basic rodent proofing (typical Fullerton home, 800 to 1,500 sq ft attic): $1,800 to $2,800
• Full GreenFiber removal, decontamination, exclusion, and re-insulation (larger homes or heavy infestation): $3,500 to $6,500+

What moves the price: attic square footage, how much contaminated GreenFiber has to be bagged and hauled, how many entry points need sealing, and whether you’re re-insulating after the cleanout. We give you a written, itemized quote before any work starts, and estimates are free. Call (657) 216-9948 and we’ll give you real numbers based on your attic, not a guess.
