About Environ
Built on 15 Years of Bay Area Crawl Spaces
Environ was founded by contractors who were tired of seeing homeowners sold quick fixes that failed within a year. We do it right the first time — engineered, documented, and guaranteed.
Our Story
Why We Started Environ
In 2009, our founder spent three years as a general contractor watching the same story play out: homeowners discovering crawl space damage, getting sold cheap plastic sheeting and a coat of paint, and calling back two years later with the same — or worse — problems.
Environ was built on a different premise. Every crawl space problem has an engineered solution. Moisture doesn't disappear because you covered it up — it needs to be redirected, controlled, and monitored. Structural damage doesn't heal — it needs to be properly repaired and the root cause eliminated.
Today, Environ is the Bay Area's most trusted crawl space contractor, with over 500 completed projects across Marin, Contra Costa, Alameda, Santa Clara, and San Mateo counties. We're still doing it the same way: right the first time.
How We Work
What Sets Us Apart
Engineered, Not Improvised
Every solution we design is based on moisture data, structural assessment, and building science — not guesswork or upselling.
Transparent Pricing
We give you a detailed scope of work and a fixed price before we start. No surprises, no change orders for work we should have anticipated.
Permitted Work
We pull permits where required. It protects you at resale and ensures the work meets California building code.
Guaranteed Results
Our encapsulation and drainage systems come with transferable warranties. If it fails, we fix it — no questions asked.
