Attic & Crawl Space Remediation
Insulation Removal in Los Gatos, CA
101 Exterminators handles insulation removal in Los Gatos, vacuuming out attic and crawl space material that roof rats have contaminated. CA licensed under SPCB Lic. #9119, working Santa Clara County since 2005. Hillside homes taking canopy rat pressure off St. Joseph's Hill and the El Sereno ridge need it most, because roof rats nest inside blown-in insulation and run the same paths through it for years.
Warning Signs
Signs You Need Insulation Removal Service in Los Gatos
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 Los Gatos
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Los Gatos.
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.
Why 101 Exterminators
Insulation Removal You Can Count On in Los Gatos
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 Los Gatos
Do I have to replace all the attic insulation after rats in a Los Gatos home, or can it be spot-cleaned?
It depends on how far the contamination spread. A small, contained nest area can sometimes be cut out and replaced without a full removal, but roof rats run continuous runways and urinate along them, so in most Los Gatos attics with an established colony the contamination reaches across the whole plane. The test is what the inspection finds: trails, droppings and compressed paths across multiple bays means full removal. We photograph it so you are deciding from evidence rather than from a recommendation.
What happens to the wiring and ductwork once contaminated attic insulation comes out?
That is when you finally get to see it, and in a rat-occupied Los Gatos attic it is often the most useful part of the job. With the material vacuumed out we photograph the exposed romex, low-voltage runs and flex duct so you know what has been gnawed and what needs an electrician or an HVAC contractor before new insulation covers it again. Duct leaks in particular are common on the 1970s stock here, and they are simple to repair while the attic is open and awkward to reach later.
Should rodent exclusion be done before or after insulation removal in a Los Gatos home?
Before, or at the same time. Sealing the entry points is what keeps the next roof rat out of a clean attic, and in Los Gatos those entries sit at roof height (vent screens, eave gaps, roof-to-wall junctions, conduit boots), because the pressure comes down the canopy from the open space above town. Removing insulation from a structure that is still open buys bedding for the next colony. We schedule the two together for exactly that reason.
