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

Aqua Guard Water Damage built its Portola Valley operation around one standard: arrive fast, document everything with moisture readings and thermal imaging, and communicate the drying plan in plain language before we touch a single wall.
We answer our own phones around the clock in Portola Valley, 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.
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.

Ceiling stains near a bathroom or kitchen almost always trace back to a plumbing failure rather than a roof leak, which means the source is often closer and easier to fix than homeowners assume.
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.
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.
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.
Dark spotting in grout lines or around window frames is often the first visible sign of a moisture problem that's been developing for weeks.
Our Basement Flooding 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.
Standing water gets removed with commercial extraction equipment first, then we run moisture readings across every affected surface so the drying plan targets what's actually still wet, not what looks dry on the surface.
Equipment placement isn't guesswork; it's calculated from psychrometric readings taken at the start of the job and adjusted daily as conditions change.
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.
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.
Once the structure tests dry, our reconstruction team handles drywall, insulation, flooring, and trim so you're not managing a second contractor after the restoration crew leaves.
Furniture, documents, and electronics affected by water intrusion get assessed on-site, with salvageable items cleaned and stored while unsalvageable items are documented for your claim.



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.
Technicians arrive with moisture meters and thermal cameras to map exactly how far the water has traveled, including inside walls and under flooring where you can't see it.
Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.
Once moisture readings confirm the structure is dry, we hand you documentation and move into any needed reconstruction.
Insurance and licensing aren't just paperwork here — they're what let us stand behind the work if something doesn't go as planned.
Trucks are staged regionally so a crew can typically reach you well before a national chain's call center even finishes your intake form.
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.
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 94028 or one of the neighboring zip codes we cover, the same crew and the same response standard applies.
Coverage isn't limited to the city center — our Portola Valley routes extend out to the surrounding suburbs so outlying addresses aren't treated as an afterthought.

"The team here in Portola Valley 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., Portola Valley"Our basement took on water during a storm and the crew classified it, extracted it, and had dehumidifiers running the same afternoon. The final invoice matched the upfront quote exactly."
Denise M., Portola Valley"The sewage backup in our laundry room was handled with full PPE and proper disposal of the ruined flooring. I appreciated that they explained the Category 3 contamination process before starting."
Marcus T., Portola Valley"Every question I asked got a straight answer, even the ones about cost, which is rare after dealing with two other contractors who kept dodging the pricing conversation."
Priya S., Portola Valley"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., Portola Valley"Coordinating a commercial job around our operating hours could have been a nightmare, but their crew worked around our schedule without us having to ask twice."
Angela F., Portola Valley"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., Portola Valley"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."
