When a pipe bursts or a storm backs up your drain lines, waiting on hold is the last thing you can afford. Our San Bruno-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 Bruno basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which San Bruno 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 Bruno 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.
A persistent musty smell in a basement or bathroom usually means microbial growth has already started somewhere you can't see, often inside wall cavities or under flooring. Air fresheners will mask it temporarily but won't touch the actual source.
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.
If your usage climbs but nothing in your household routine changed, a hidden leak behind a wall or under the foundation is worth investigating immediately, since slab leaks rarely announce themselves any other way.
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.
Any visible mold, even a small patch in a corner or along a baseboard, means conditions behind that surface have supported growth for a while and the moisture source needs to be found, not just the mold wiped away.
Our Structural Drying 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.
Category 3 blackwater intrusions require full PPE, controlled demolition of porous materials that can't be sanitized, and hospital-grade antimicrobial treatment before reconstruction begins.
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.
The assessment sets the entire plan — skipping it or rushing it is how jobs end up with hidden moisture pockets months later.
Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.
Final verification is where a lot of shortcuts get taken industry-wide — we treat it as mandatory, not optional.
Every technician carries IICRC certification and our crews are fully insured for your protection on every job.
Trucks are staged regionally so a crew can typically reach you well before a national chain's call center even finishes your intake form.
You get a written estimate before work begins, not a surprise invoice after the drying equipment is already running.
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.
Call +1-844-234-5373Whether your address falls in 94066 or one of the neighboring zip codes we cover, the same crew and the same response standard applies.
We track call volume by zip code across San Bruno to keep crew staffing matched to where emergencies actually happen most often.
"A pipe burst behind our water heater and the crew here in San Bruno had extraction units running within 40 minutes of my call. They walked me through the moisture readings every day until it was fully dry."
James R., San Bruno"They caught mold starting behind our drywall before it spread and contained it properly instead of just painting over the problem like a previous contractor did."
Denise M., San Bruno"They didn't cut corners on the contaminated water cleanup even though it would have been faster to skip the sanitization step — that mattered to me given we have young kids in the house."
Marcus T., San Bruno"Fast response, clear pricing, and they coordinated directly with my insurance adjuster which saved me a huge headache during a stressful week."
Priya S., San Bruno"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 Bruno"Our commercial unit flooded overnight and they had industrial equipment running before our staff arrived for the morning shift."
Angela F., San Bruno"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 Bruno"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 Bruno
