Aqua Guard Water Damage has spent years pulling water out of San Anselmo basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which San Anselmo 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 Anselmo 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.
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.

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.
Musty odors that seem to follow you from room to room often mean the HVAC system is circulating spores from a hidden wet area, which spreads the problem rather than solving it.
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.
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 Mold Remediation 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.
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.
Because mold can establish in as little as 48 hours, our drying timeline is built around beating that window rather than treating mold prevention as an afterthought.
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.
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.
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.
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.
A guarantee only means something if it's backed by a second set of moisture readings, not just a handshake at the end of the visit.
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.
Our technicians don't get paid faster by closing jobs early, which keeps the incentive aligned with actually finishing the drying properly.
Call +1-844-234-5373Whether your address falls in 94960 94978 94979 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 Anselmo to keep crew staffing matched to where emergencies actually happen most often.

"The team here in San Anselmo 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 Anselmo"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., San Anselmo"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 Anselmo"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 Anselmo"Drying logs were shared with us daily so we always knew exactly where the job stood, not just a vague 'it's drying' update."
Carlos V., San Anselmo"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., San Anselmo"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 Anselmo"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."
