Attic & Crawl Space Remediation
Insulation Removal in Palo Alto, CA
101 Exterminators does insulation removal in Palo Alto where roof rats have been living in an attic or a sub-area — HEPA-filtered vacuum removal, disinfection, and exclusion sealing before anything new goes back. We are licensed in California under SPCB Lic. #9119 since 2005. Palo Alto's mature tree canopy keeps roof rat pressure high in Crescent Park, Old Palo Alto and Duveneck/St. Francis, and contaminated insulation is what we find afterward.
Warning Signs
Signs You Need Insulation Removal Service in Palo Alto
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 Palo Alto
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Palo Alto.
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 Palo Alto
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 Palo Alto
Does the insulation in my Palo Alto attic need to come out, or can I just add more on top?
Contamination decides that, not depth. If the blown-in material has runways compressed through it, droppings on the surface, a strong ammonia odor, or nesting cavities, it needs to come out — adding new insulation on top seals the contamination in and does nothing about the smell or the attraction. If the material is simply thin, flattened with age and clean, adding depth is reasonable. We photograph what is up there so you are looking at the same evidence we are.
Is there hantavirus risk in a Palo Alto attic?
The risk in an urban Palo Alto attic is low, because the hantavirus reservoir in California is the deer mouse, an open-space and rural species rather than a roof rat. Rodent droppings and urine of any species can still carry other organisms, and disturbing dried material makes it airborne. That is why the work uses HEPA-filtered vacuum equipment, containment and respiratory protection instead of sweeping. Properties along the Foothills and Pearson-Arastradero edge are where deer mice are more plausible.
Can insulation be removed from an Eichler that has no attic?
Yes, but it takes access cuts rather than a hatch. Post-and-beam houses in Greenmeadow, Fairmeadow and Charleston Meadow have low-slope roofs with little or no attic, so contaminated material sits in whatever cavity exists — furred-down soffits, mechanical chases, garage ceilings, and any space created when the roof was re-decked or re-insulated. We open the minimum number of points needed to reach and vacuum it, disinfect, then close and patch. The sealing work comes first either way.
