Aqua Guard Water Damage built its San Quentin 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.
Every technician on our San Quentin 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.

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.
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.
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.
Bubbling near a window or exterior wall frequently points to a flashing or seal failure letting water into the wall cavity a little at a time.
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 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.
We place industrial air movers and low-grain-refrigerant dehumidifiers based on psychrometric readings, then log moisture levels daily until every affected material returns to a safe drying standard.
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.
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.



You call +1-844-234-5373 and speak with a live dispatcher, not a voicemail system — we ask a few quick questions about the source and severity so the crew arrives prepared.
The assessment sets the entire plan — skipping it or rushing it is how jobs end up with hidden moisture pockets months later.
We set drying equipment based on the specific moisture readings taken during assessment, not a generic placement pattern.
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.
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.
Every job closes with documented moisture verification, because a guarantee that isn't backed by data isn't much of a guarantee.
Our technicians don't get paid faster by closing jobs early, which keeps the incentive aligned with actually finishing the drying properly.

"I called in a panic at 11pm and someone actually picked up. The tech here in San Quentin had air movers set up before midnight and explained exactly what they were doing and why."
James R., San Quentin"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 Quentin"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 Quentin"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., San Quentin"We had a slow leak we didn't notice for weeks and the crew found moisture in places we never would have checked using thermal imaging."
Carlos V., San Quentin"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., San Quentin"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 Quentin"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."
