Attic & Crawl Space Remediation
Insulation Removal in Daly City, CA
101 Exterminators handles insulation removal in Daly City for attics and crawl spaces that rodents have contaminated or fog-driven moisture has ruined, California licensed under SPCB Lic. #9119 since 2005. Roof rats nest in blown-in attic insulation across the Westlake and Serramonte tracts, and damp under-floor batts sag out of the joist bays. We seal the entry points before anything comes out.
Warning Signs
Signs You Need Insulation Removal Service in Daly City
Complete removal of blown-in or batt insulation from attics using industrial HEPA-filtered vacuum equipment. Spot removal of specific contaminated areas in crawl spaces. After removal, we apply disinfectant to surfaces and can coordinate insulation reinstallation. Rodent exclusion work is performed prior to or concurrent with insulation removal to prevent re-infestation after new insulation is installed.
Rodent activity confirmed in attic — droppings, tracks, gnaw marks, or nesting visible in insulation
Strong ammonia smell from attic — indicates heavy rodent urination throughout insulation
Water damage to ceiling indicating roof leak that has saturated attic insulation
Insulation age over 20 years — blown-in insulation settles and loses R-value significantly over time
Pest inspection report noting contaminated insulation as a Section 2 condition
How It Works
Our Insulation Removal Process in Daly City
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Daly City.
Assessment & Safety Review
We assess contamination extent, access points, insulation type, and identify any asbestos indicators that would require different handling protocols.
Rodent Exclusion First
If rodents are active, we seal entry points before beginning removal — installing new insulation before resolving active infestation is counterproductive.
HEPA-Vac Removal
Contaminated blown-in insulation is vacuumed out using HEPA-filtered equipment that contains particulates. Batt insulation is bagged and removed in sealed bags.
Disinfection & Deodorization
Surfaces are disinfected with enzyme-based or quaternary ammonium cleaners to address urine, feces, and nesting materials. Deodorization is applied as needed.

Insulation Removal You Can Count On in Daly City
Health Safety Priority
HEPA-filtered removal prevents aerosolization of contaminated particles during extraction. Our team uses N95 or higher respiratory protection throughout.
Coordinated with Exclusion
We do not simply remove and replace insulation without addressing active rodent entry — that would just contaminate the new insulation. Exclusion and removal are coordinated.
Common Questions
Insulation Removal FAQs for Daly City
How do I know if rat-contaminated attic insulation in my Daly City home needs full removal?
The test is how far the runways and staining run, not how many droppings you can see from the hatch. Scattered droppings on top of batts near the access can be spot-cleaned. Tunnels crossing the attic, matted nesting material and urine staining through blown-in insulation mean the layer is compromised — it holds odor that attracts new rodents and has lost most of its thermal value. We inspect the far corners first, because Daly City attics are low-slope and the worst damage is rarely near the hatch.
Our crawl space insulation is falling out of the joists. Is that a moisture problem?
Almost always, in this city. Fiberglass batts under a floor absorb humidity rising from bare soil, get heavy, and pull away from the joist bays and their supports. Daly City crawl spaces stay damp through the summer fog and again through the winter rains, so the material rarely dries out between cycles. Removing it is straightforward; what matters is correcting the ground moisture with a vapor barrier and drainage before any new insulation goes in.
Can insulation come out of a Daly City attic without the crew tracking through the house?
Yes, and it takes planning, because most of these tract homes have one small hatch in a hallway or the garage. We lay protective covering along the route, run the vacuum hose from the truck to the hatch, and bag batt material at the opening so nothing travels loose through living space. Where the garage hatch gives better access we work from there instead. Access limits get discussed before the day rather than on it.
