A flooded basement doesn't wait for business hours, and neither do we. Aqua Guard Water Damage keeps trucks staged around San Mateo so a licensed technician can be pulling standing water within the hour, not scheduling you for next Tuesday.

Our San Mateo technicians hold IICRC water restoration certifications and carry that training into every job, from a Category 1 clean-water leak to a Category 3 sewage backup. We're not a call center routing you to a random subcontractor; we're the crew that shows up.
We answer our own phones around the clock in San Mateo, which means the person who books your appointment already knows our schedule, our crew availability, and how fast we can realistically get a truck to your address.
Beyond the technical certifications, our crews are trained to communicate clearly under pressure, because a homeowner dealing with a flooded home deserves plain answers, not jargon.
A stain that keeps reappearing after you paint over it is a signal, not a coincidence — the moisture source behind the wall hasn't been addressed and needs a moisture meter reading, not a fresh coat of paint. Repainting without finding the source just hides the problem for a few more weeks.
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.
Tile that suddenly sounds hollow when you tap it often means the mortar bed underneath has been sitting in moisture long enough to lose adhesion. That hollow sound rarely resolves on its own.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Wallpaper that lifts at the seams after being fine for years is often a sign that humidity or a slow leak has changed the moisture level inside that wall.
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 Ceiling Water Damage Repair 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.
Our crews arrive with truck-mount extraction units capable of pulling thousands of gallons per hour, using moisture meters to classify the water as Category 1, 2, or 3 before drying even starts.
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.
Blackwater jobs get treated with extra caution, since porous materials that touched contaminated water almost always need to be removed rather than dried in place.
If mold has already taken hold, our containment and remediation process isolates the affected zone with negative air pressure before any demolition begins, keeping spores from spreading to unaffected rooms.
We handle everything from replacing water-damaged drywall and insulation to refinishing floors, so the property is restored to pre-loss condition under one contract instead of three.
Specialized cleaning techniques can often save upholstery, electronics, and documents that look like a total loss at first glance, which keeps out-of-pocket replacement costs down.
A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
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.
Insurance and licensing aren't just paperwork here — they're what let us stand behind the work if something doesn't go as planned.
Local staging means shorter drive times, which matters most in the first hour after a water loss.
Flat-rate pricing means the number we quote is the number you pay, regardless of how long the drying cycle takes.
If a drying target isn't met on the first pass, we extend equipment placement at no extra charge until moisture readings confirm the structure is dry.
If our moisture readings don't hit a safe drying standard on schedule, we keep equipment on site at no additional cost until they do — that's the standard we hold ourselves to.
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"Our commercial unit flooded overnight and they had industrial equipment running before our staff arrived for the morning shift."
Angela F., San Mateo"The tech explained exactly which boards needed to come out and which ones tested dry enough to keep, so we didn't pay to replace more than necessary."
Tyrone B., San Mateo"Storm runoff got into our crawl space and the smell alone told us something was wrong. The crew found the vapor barrier had failed and fixed the actual cause, not just the symptom."
