Knauf Attic Cleaning & Rodent Proofing in Santa Monica: What to Know First
Knauf attic cleaning and rodent proofing in Santa Monica typically runs $1,250 to $4,500 depending on attic size, contamination level, and whether we’re doing a full exclusion job or a targeted repair. We’re Walt’s Insulation, an independent Knauf service provider, and most jobs in Santa Monica take one to two days from start to finish, including sanitizing and sealing entry points. We’re not authorized by Knauf, and we won’t pretend to be. What we are is a locally owned Santa Monica-area crew that’s been pulling rodent nests out of Knauf-insulated attics since the early 2000s. If rats or mice have gotten into your Knauf EcoBatt, Knauf Jet Stream, or Knauf R-38 blown-in fiberglass, call (424) 396-5828 and a live person picks up, day or night.
How Knauf Products Fail and How We Fix Them
- Knauf EcoBatt R-30 / R-38 batts hold odor like a sponge. The binder in EcoBatt fiberglass has a slight starch content, and once rodents urinate and nest in it, the smell lingers even after the rodents are gone. You can’t wash it out. The fix is removing the contaminated batts, sanitizing the decking, and reinstalling fresh Knauf or equivalent material. We see this constantly in older Santa Monica bungalows near Montana Avenue where vent screens rotted out in the salt air.
- Knauf Jet Stream blown-in fiberglass compacts under rodent traffic. Rodents create tunnels through blown-in insulation, and the weight of their traffic plus nesting crushes the loft. Loose-fill Knauf that should sit at 12 inches ends up at 4 to 5 inches in the traffic paths. That means cold spots in winter and hot ceilings in summer. We vacuum out the damaged zones, sanitize, and re-blow to the correct depth for Santa Monica’s marine climate.
- Knauf R-13 / R-19 faced batts hide entry points. The kraft paper facing on faced Knauf batts makes it nearly impossible for a homeowner to spot where rodents are entering from the soffit line or wall top plates. A tech who knows what to look for can trace the grease marks and torn facing back to the actual hole. Rodents chew through the paper facing to get to the fiberglass, and that paper is also a food source for silverfish and roaches once it’s been gnawed.
- Knauf Insulation Board (rigid foam) gets tunneled in knee walls. In Santa Monica homes with finished attic bonus rooms or cathedral ceilings, we see Knauf rigid foam board chewed straight through. It’s a quieter material than fiberglass, which rodents actually like. Exclusion means metal flashing over the tunnels plus sealing the access points, not just patching foam. Foam without exclusion is a temporary fix.
- Knauf Attic Access panel gaps are a standing invitation. Many Santa Monica homes have factory or builder-installed attic hatches that were never weatherstripped or sealed after the original install. Rodents squeeze through a gap the width of a pencil. On Knauf service calls we pull back the hatch trim, check for daylight gaps, and seal with metal or hardware cloth before we even start on the insulation.
Our Knauf Attic Cleaning & Rodent Proofing Process
- 1
Call and talk to a person. You reach a live person at (424) 396-5828, 24/7. We ask about what you’re hearing, seeing, and smelling, then schedule a window that works. No voicemail tag.
- 2
Attic inspection and entry-point mapping. We suit up, go in, and find every hole, chew mark, and droppings trail. On a Knauf job, we’re looking specifically at how the insulation type is hiding or highlighting the entry paths.
- 3
Removal and sanitizing. We vacuum out contaminated Knauf insulation using HEPA-filtered equipment, bag it, and haul it out. Then we treat the decking and framing with a hospital-grade sanitizer that kills bacteria and neutralizes odor. If the decking is saturated, we may recommend a sealing coat before new insulation goes in.
- 4
Exclusion and proofing. We seal entry points with galvanized hardware cloth, metal flashing, and rodent-proof foam rated for exclusion. We don’t patch holes with spray foam alone. On a Knauf attic that means metal over every penetration, vent screen replacement where the salt air has rusted them out, and hatch weatherstripping.
- 5
Re-insulation and final check. We re-blow or re-batt to the correct R-value for Santa Monica’s climate zone and confirm the space is sealed. Then we walk you through what we found and what we fixed, so you know exactly what was done.
- 6
Done Right Promise. Every job carries our lifetime workmanship guarantee. If it’s not done right, we make it right. No runaround, no second invoice.
What Knauf Attic Cleaning & Rodent Proofing Costs in Santa Monica
Here’s what we typically see in Santa Monica, based on attic size and contamination level:
- Basic attic cleanout, no active rodent issue: $900 to $1,500 for a standard 1,200 square foot attic. Vacuuming out old or dirty Knauf insulation, sanitizing, and hauling it away.
- Full rodent decontamination and sanitizing: $1,500 to $3,200 including HEPA vacuuming, enzyme treatment, and odor sealing. Rodent urine saturation drives the price up, and older Knauf EcoBatt holds more of it.
- Complete exclusion and proofing: $800 to $2,500 depending on how many entry points and what materials are needed. Metal work and vent screens cost more than foam, and we won’t skip the metal.
- Full restoration including re-insulation: $3,000 to $6,500 for a Santa Monica attic with heavy contamination plus new Knauf or equivalent blown-in or batt insulation to correct R-value.
What moves the price: attic size, how long the rodents have been there, whether the decking needs sealing, and how many entry points exist. Every quote is upfront and specific.

Why Santa Monica Homeowners Call Walt’s Insulation for Knauf Work
We’ve been in Santa Monica attics since the early 2000s, back when a lot of these homes were getting their first real insulation retrofit. Walt Brenner learned the trade at St. Philip’s College in San Antonio before heading west, and he’s been in enough attics here to know how the marine air off the Pacific eats sealant, rusts vent screens, and invites rodents through the tiniest gaps. We’re the one down the road: a real owner, a published address, and a license you can look up. This isn’t a franchise with an 800 number and a rotating cast of subcontractors. Background-checked, uniformed technicians show up on time and answer to the same person who answered your call. We service every major insulation brand including Knauf, Owens Corning, Johns Manville, Rockwool, CertainTeed, and for reflective products, Reflectix. If it’s a Knauf attic, we know what’s in there and how to get it right.
FAQs
Yes. Knauf’s warranty covers manufacturing defects, not contamination or damage from rodents, insects, or moisture. That’s why cleaning and proofing before you re-insulate matters. We’ll help you document everything for any future claims, and our workmanship carries a lifetime Done Right Promise regardless of what the insulation warranty covers. Call (424) 396-5828 if you’re uncertain about your specific situation.
Yes. We install Knauf EcoBatt, Jet Stream blown-in, and Knauf insulation board, so if you want to match what’s already in your attic, we can source it fresh. In most cases, re-baiting with the same line in the correct R-value keeps everything consistent and avoids mixed-material issues. If Knauf is backordered locally, we’ll tell you upfront and give you equivalent options from Owens Corning or Johns Manville.
We answer live, 24/7, and we schedule emergency calls with priority. Most active rodent issues in Santa Monica get an inspection within 24 to 48 hours. The actual cleaning and proofing typically takes one to two days. Call (424) 396-5828 and tell the person who answers it’s active. We’ll move fast.
No. Layering clean insulation over contaminated Knauf traps the odor, the bacteria, and whatever else is in there. It also hides the moisture problem that’s likely already forming. You end up paying twice: once for the shortcut, and once for us to come back and do it right. Do it right once. Everything else is just a second invoice.
