Knauf Attic Cleaning & Rodent Proofing in West Hollywood: What to Know First
We clean and rodent-proof attics insulated with Knauf products throughout West Hollywood, and most jobs are finished in a single day. A typical Knauf attic cleanout with sanitizing and exclusion work runs $900 to $2,800 depending on square footage, how long rodents have been active, and whether the insulation itself needs removal. If you’re seeing droppings in the attic, hearing scratching at night, or noticing a musty smell coming from the ceiling, call us at (213) 527-4062 and we’ll give you a straight answer about what you’re dealing with. This page is for West Hollywood homeowners who own a home insulated with Knauf fiberglass or mineral wool and want to understand what attic cleaning and rodent proofing actually involves, what it costs here, and why the insulation brand in your attic changes how the job gets done.
How Knauf Products Fail - and How We Fix Them
Knauf makes solid insulation, but attics are hostile places. After 25 years of crawling through West Hollywood attics, we know exactly how Knauf materials break down under real conditions, especially when rodents move in. Here’s what we see most often.
- Knauf EcoBatt fiberglass batt compression from rodent traffic. Rats and mice don’t just nest in insulation, they carve highways through it. Those compressed paths drop the R-value by 40% or more in the affected areas, and the constant back-and-forth grinds the fibers into fine dust. We remove the soiled and compressed batts, sanitize the decking, and install fresh Knauf EcoBatt or a comparable batt at the correct loft and density.
- Knauf Jet Stream blown-in fiberglass matting and settling after water intrusion. When rodents chew through a roof vent or a plumbing boot and let West Hollywood’s winter rain into the attic, blown-in Knauf fiberglass mats down and loses its insulative air pockets. Homeowners often mistake this for normal settling. It’s not. We extract the wet, matted material, dry and sanitize the attic floor, and re-blow to the proper depth for our climate zone.
- Rodent nesting inside Knauf R-38 batts at the eaves. The eaves, especially on older stucco homes near the Santa Monica Boulevard corridor, are where we find the worst Knauf damage. Rats love the quiet, tucked-away corner where the roof meets the exterior wall. They shred the batts for nesting material and leave urine-soaked pockets that hold odor for years. We remove the contaminated sections entirely, fog the cavity with a hospital-grade disinfectant, and seal the eave gaps before replacing the insulation.
- Knauf mineral wool boards chewed into at access points. Some West Hollywood condos and older apartment conversions use Knauf mineral wool boards around HVAC chases and party walls. Rodents gnaw through them to travel between units. The fix isn’t more mineral wool, it’s proper exclusion first: steel mesh, foam sealant, and hardware cloth at every penetration. Then we patch the Knauf board with the correct thickness to restore the fire rating.
- Fiberglass contamination from rodent feces and urine in Knauf blown-in coverage. This is the one homeowners hate to hear: once rodents have lived and defecated in blown-in Knauf insulation for more than a few weeks, cleaning the surface isn’t enough. The contamination works down into the material. In those cases, full removal and replacement is genuinely the right call, and we’ll show you the evidence before we recommend it.

What Knauf Attic Cleaning & Rodent Proofing Costs in West Hollywood
Here’s the honest price posture for Knauf attic work in West Hollywood. These are real ranges based on the jobs we’ve done in this city.
- Basic attic sanitizing and deodorizing (no insulation removal): $400 to $900
- Rodent exclusion and proofing (sealing entry points, steel mesh, foam): $600 to $1,800 depending on roof complexity and the number of access points
- Full Knauf blown-in insulation removal, sanitizing, and replacement: $1,800 to $4,500 for a typical 1,200 to 1,800 square foot attic
- Knauf batt removal and replacement at eaves or isolated areas: $800 to $2,200 depending on how much material is contaminated
What moves the price: how long the rodents have been in the attic, whether the contamination is surface-level or worked deep into the Knauf material, attic accessibility (some older West Hollywood homes have tight scuttle holes that make removal slower), and whether structural repairs are needed after the rats chewed through framing or conduit. Estimates are free, and we’ll stand behind the number we give you. Call (213) 527-4062 for an exact quote.

FAQs
No. Knauf’s insulation warranty covers manufacturing defects in the material itself, not conditions caused by rodents, water, or attic contamination. As an independent Knauf service provider, we work carefully to preserve any intact insulation that can be safely kept, and we document everything so you have a clear record for any future warranty discussion with the manufacturer. We are not affiliated with or authorized by Knauf, but our work is done in a way that respects the product’s intended performance.
In most cases we can have a technician at your West Hollywood home within 24 to 48 hours. Emergency rodent situations, like a rat that’s chewed through wiring or died in the attic, can often be scheduled same-day. Call (213) 527-4062 and a live person will tell you exactly when we can be there.
It depends on how deep the contamination goes. Light surface dust and a few droppings can usually be cleaned and sanitized in place. But if rodents have nested in the Knauf material for weeks or months, the urine and feces work down into the fiberglass and cannot be fully removed without replacing the material. We’ll show you photos and give you an honest recommendation, not a sales pitch. If you have a written estimate from another company, bring it and we’ll give you a free second opinion.
We seal every entry point a rodent can use: eave gaps, roof vent edges, plumbing penetrations, AC chase openings, and any gap larger than a dime. We use steel mesh, hardware cloth, and expanding foam in combination, then recheck the entire perimeter. Rodent proofing only works if every entry is sealed, so we’re thorough about it. The Done Right Promise covers this work for life.
We’ll do everything we can. Call (213) 527-4062 as early as possible and we’ll let you know if a same-day slot is open. A live person answers, 24/7, and we’ll give you a straight answer about timing and cost before anyone sets foot in your house.
