When a pipe bursts or a storm backs up your drain lines, waiting on hold is the last thing you can afford. Our San Mateo-based crews carry moisture meters and truck-mount extraction equipment on every rig so the drying process starts the moment we knock on your door.

Aqua Guard Water Damage has spent years pulling water out of San Mateo basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which San Mateo neighborhoods sit on older clay pipe, which developments have a history of sump failures, and which zip codes flood first when storm drains back up.
Every technician on our San Mateo roster is background-checked, licensed, and insured, and every truck is stocked with commercial-grade air movers, low-grain-refrigerant dehumidifiers, and antimicrobial treatment for contaminated water intrusion.
We also carry direct experience working alongside insurance adjusters, so the documentation we generate on day one is already formatted the way most carriers expect to see it.
Yellow-brown rings on your ceiling or walls almost always mean water has been sitting behind the surface longer than you think, and the drywall paper backing is likely already feeding mold growth. Waiting to see if the stain spreads only gives moisture more time to travel further into the structure.
If opening windows and running a fan doesn't clear the smell within a day, the moisture source is still active and needs professional extraction, not just ventilation. A smell that returns after cleaning is a strong sign the moisture is still present.
Carpet that stays damp or squishy days after you last noticed water is holding moisture against the subfloor, which is exactly the condition that lets mold take hold underneath.
An unexplained jump in your water bill is frequently the first sign of a slab leak or a failing supply line long before any visible water appears. Catching it at this stage is far cheaper than waiting for a visible flood.
Paint that bubbles or peels away from a wall, especially near baseboards, usually means moisture is pushing through from behind rather than a simple application problem.
Mold that returns after cleaning with bleach is a sign the underlying moisture source was never addressed, since surface cleaning does nothing for saturated material behind the wall.
Our Burst Pipe Cleanup process covers every stage of a water loss, from the first extraction pass to the final coat of paint, so you're never left coordinating separate contractors mid-project.
We prioritize extraction speed above everything else in the first hour, because every additional hour standing water sits raises the odds of secondary damage to subfloors and framing.
Drying logs track humidity, surface moisture, and airflow at every checkpoint, so you get documented proof the structure is dry before we close out the job — useful for your insurance claim too.
Our sewage cleanup protocol follows IICRC S500 contamination standards, isolating the affected area, removing unsalvageable materials, and disinfecting every surface that had contact with blackwater.
Once structural drying is underway, we apply antimicrobial treatments to studs, subfloor, and other porous surfaces to stop mold colonies before they establish, especially in areas that stayed wet more than 48 hours.
The same team that documented the damage and dried the structure hands off directly to reconstruction, which keeps the whole timeline shorter and the paperwork simpler.
We inventory and pack out contents that need to leave the affected area during drying, then coordinate their return once the space is verified dry and repairs are complete.
Dispatch asks enough to prep the right equipment before the truck even leaves, so the crew isn't guessing what they'll find on arrival.
We document the loss with photos and moisture readings before touching anything, which also protects your insurance claim.
Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.
We re-test every affected area before calling a job complete, then coordinate repairs so you're not left with an open punch list.
Every technician carries IICRC certification and our crews are fully insured for your protection on every job.
A crew close by isn't a marketing line — it's the difference between drying equipment running in an hour versus waiting half a day.
Flat-rate pricing means the number we quote is the number you pay, regardless of how long the drying cycle takes.
We stand behind every job with a documented re-inspection before we consider the work complete.
We'd rather run drying equipment an extra day at our own cost than close out a job with a moisture reading we're not confident in.
That same standard applies whether it's a single flooded bathroom or a full commercial loss — the sign-off criteria don't change based on job size.

"The team here in San Mateo treated our emergency like it actually mattered, not like another ticket in a queue, and the drying documentation they left us was thorough enough to hand straight to our insurer."
James R., San Mateo"What impressed me most was the daily moisture log — I could actually see the numbers improving instead of just being told to trust the process."
Denise M., San Mateo"Professional from the first phone call to the final walkthrough. They re-tested moisture levels before closing the job instead of just eyeballing it."
Marcus T., San Mateo"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., San Mateo"The thermal imaging inspection found damage behind a cabinet we never would have thought to check, which probably saved us from a much bigger mold problem down the road."
Carlos V., San Mateo"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., San Mateo"A cracked supply line under the kitchen sink went unnoticed for days and by the time we called, the subfloor was saturated. The crew pulled the damaged material and had drying equipment running within the hour."
Tyrone B., San Mateo"They explained the sump discharge issue causing our crawl space flooding in plain terms and fixed it as part of the same visit instead of scheduling a separate appointment."
Wendy K., San Mateo
