Whether it's a slow leak that's been eating your subfloor for weeks or a flooded basement at 2am, our San Mateo crews are already moving. Hirex Water Damage sends licensed technicians straight to your San Mateo address with extraction equipment already loaded and running.

Hirex Water Damage started because homeowners in San Mateo, CA kept telling us the same story: a national hotline picked up, put them on hold, and then subcontracted the job out to whoever was cheapest and closest. Every technician on our San Mateo roster is a Hirex Water Damage employee, not a gig-app contractor pulled from a random directory.
Each lead tech holds an IICRC Water Restoration Technician certification and has personally handled clean-water, gray-water, and contaminated black-water losses, so Water Damage Repair in San Mateo isn't a side service we tacked on β it's the reason the company exists. We're fully insured and licensed to work anywhere in San Mateo, CA, so you're protected from the moment our truck pulls into the driveway.
We keep a stocked warehouse inside San Mateo, CA so equipment never has to be trucked in from another region, which is the difference between a 45-minute arrival and a next-day one.
Ask any San Mateo property manager who has dealt with a burst supply line at 3am β the difference between a crew that shows up ready and one still loading a truck at the shop is measured in gallons of water soaking into your subfloor. That's the gap Hirex Water Damage was built to close, one San Mateo call at a time.
