A Bay Area team that treats your home like our own.
Johnson's Insulation is a family-run contractor based in Oakland. Since 2014 we've helped homeowners across the East Bay, Peninsula and South Bay make their homes quieter, healthier and dramatically more efficient.
"We started Johnson's Insulation because too many homeowners were being sold work they didn't need. Our promise is simple — we treat every attic and crawl space the way we'd want a contractor to treat ours."

Done-right install
Detailed air sealing, proper R-values, and tidy crawl space and attic finishes you'd be happy to show off.
Built in Oakland, trusted across the Bay.
Johnson's Insulation opened its doors in 2014 with one truck, two installers and a belief that insulation work should be careful, transparent and built to last.
A decade later we're a full-service attic, crawl space and wall insulation company serving every major Bay Area neighborhood. We're BPI Certified, partnered with BayREN and PG&E rebate programs, and proud of the homeowner reviews we've earned along the way.
Every project still goes through the same checklist our founders wrote on day one — because the details are what make a house comfortable for the next 20 years.
