Whether it's a slow drip that finally gave out or a sudden flood at midnight, San Mateo residents call one number and get a real answer. Our San Mateo-based teams roll out with extraction and drying gear already loaded, not scrambling to gather it after the call.


We built Hirex Water Damage's San Mateo operation after hearing the same complaint over and over: the "24/7" number that never actually answers when it matters. Every technician you'll meet is a direct Hirex Water Damage employee, not a subcontractor pulled from an app.
Certification isn't just a logo on our site — our San Mateo crew leads have logged real hours on clean, gray, and contaminated water losses, which is why Emergency Water Damage in San Mateo is treated as a specialty, not a side offering. We carry full liability coverage and hold active licensing to operate throughout San Mateo, CA.
Local equipment staging is the difference between a 45-minute arrival and a next-morning one for San Mateo calls.
Talk to a San Mateo landlord who's lived through a burst supply line at 3am and they'll confirm that response speed, not just skill, determines how much a job ends up costing. That gap between a fast, equipped response and a slow, improvised one is exactly what Hirex Water Damage was built to close.
We also invest in ongoing technician training, since restoration methods and equipment keep evolving and a San Mateo crew running outdated techniques does the property a disservice.

The San Mateo jobs that end up gutting a room almost always started quiet, not with a flood. Here's what tells our team a San Mateo property needs a professional look rather than a mop and a fan:
If any of that sounds familiar, don't wait for it to get worse — call our San Mateo line and we'll give you a straight answer on urgency.
Whether it's a small residential leak or a large commercial loss, our San Mateo teams size the crew and equipment to fit. Every service below reflects a specific piece of equipment or protocol, not just a marketing category.
Our San Mateo units carry truck-mount extraction pumps that pull standing water out fast, cutting exposure time from days to hours. Moisture mapping follows every extraction so we know which materials are still holding water once the visible flooding is gone.
We calculate drying needs using humidity and temperature data rather than guessing at equipment placement, with daily logs so you can watch the numbers improve.
For San Mateo families, our scope covers flood-cut work, subfloor evaluation, and packing out belongings that can be cleaned and restored, with photo documentation at every stage for your insurance file.
San Mateo businesses and property managers get a dedicated project lead, after-hours crews, and equipment scaled to square footage — a flooded lobby or a leaking unit above tenants has to move fast.

We treat affected materials during every San Mateo job specifically to lower mold risk, and flag anything that needs deeper remediation.

Extraction happens right away, with drying equipment placed only after moisture mapping is complete.
We re-check moisture daily until materials hit dry standard, then hand you full documentation for your records.

We measure moisture with instruments, not guesswork, and won't sign off on a San Mateo job until readings match the dry standard for the materials involved. If a callback within 30 days shows lingering moisture from the same loss, we return and correct it at no additional charge.
That commitment is written into every San Mateo work order we issue, not just mentioned in a sales pitch. If a follow-up visit is ever needed, we send a technician familiar with the original job whenever scheduling allows, so you're not re-explaining the situation to someone new.
A guarantee only means something if it's backed by documented numbers, which is why every San Mateo job closes with instrument readings attached.
