Stop crawl space moisture, standing water, and damage before they get worse. Attic Pros installs vapor barriers, drainage solutions, and moisture-control systems designed for your home — not quick fixes.
Free inspection · No pressure · We come to you
"Thank you ATTIC Pros for a job well done. Great communication, on time and wonderful service"
What We Install
We design every installation around how your crawl space handles moisture — not around a cookie-cutter checklist. Vapor barriers, drainage, and humidity control work together to match your foundation, soil, and Bay Area weather conditions.
Service 01
Vapor Barrier Systems
Heavy-duty vapor barriers help seal exposed soil and reduce ground moisture. Sealed seams and key penetrations help create a cleaner, drier crawl space.

Service 02
Interior French Drains
Interior drainage channels help collect and route water away from the crawl space perimeter. When needed, they can be paired with a sump pump system for active water management.

Service 03
Sump Pump Systems
Pump-assisted systems help remove collected water from the crawl space and route it away from your foundation when gravity drainage is not enough.
Active water removal.Backup options available.
Service 04
Moisture Control Systems
Humidity-control recommendations help reduce condensation, musty odors, and recurring dampness — especially during Bay Area wet seasons.

Warning Signs
Most homeowners don’t discover crawl space water problems until they’re already expensive. These are the signs you need a waterproofing professional — not a dehumidifier.
Standing Water After Rain
Water pooling under your home means inadequate drainage. It doesn’t dry out — it soaks into wood and soil, causing progressive damage.
Persistent Musty Odor
That smell drifting up through your floors is mold spores. Crawl space air infiltrates living spaces — you breathe what’s down there.
Soft or Bouncy Floors
Moisture-damaged floor joists lose structural integrity. What feels like a minor bounce is often rotting wood that needs immediate attention.
Cold Floors in Winter
Uncontrolled crawl space air directly affects floor temperature and your heating costs. Proper moisture control fixes both.
Pest Activity
Wet crawl spaces attract termites, rodents, and insects. Moisture is the magnet — eliminate it and you eliminate the habitat.
White Powdery Residue
Efflorescence on concrete walls or piers means water is actively migrating through. It signals ongoing hydrostatic pressure.

Real Customers, Real Results
The Attic Pro team was amazing! Mynor Hernandez was fantastic! He kept me up to date on status and timeline. When complete, he shared photos of his team's excellent workmanship.
The workers arrived on time were professional and explained everything they were doing very well. Work proceeded in an expeditious manner, and everything was very well done. And the cleanup was excellent.
I bought an older house that hadn’t been maintained for years. There were a lot of entry points for rats to enter the attic, crawl space, and garage. I needed work on the HVAC, asbestos in the crawl space, insulation in the attic, as well as rat exclusion. The issue had gotten out of control and they were able to help at a much more affordable rate than all the other estimates I’d received. ...
Jose Olguin did an outstanding job finishing and inspecting work done on my house so professional loved him coming out and making sure everything was done properly .Attic Pro's great company.
