About AttiCali EcoShield.

AttiCali EcoShield is a licensed, insured and bonded contractor based in San Jose. We work in attics, crawl spaces and garages across the whole Bay Area.

What we do

Insulation, attic and crawl space cleaning, and pesticide-free rodent proofing. Most of the work is inside the home: the attic, the crawl space and the garage. Sealing the outside entry openings, like vents, eaves and roof gaps, is part of rodent proofing.

We seal with galvanized steel mesh, putty and concrete. Never foam, and no poison.

Licensed, insured and bonded

California contractor license #1149346 (C‑2 Insulation, C‑20 HVAC). You can look it up on the CSLB website.

How we work

Every job starts with a free inspection. We photograph what we find, explain it, and send a written quote, usually within 30 to 60 minutes of the inspection and the same day at the latest. Every item is listed, so you can compare it line by line.
