A flooded basement doesn't wait for business hours, and neither do we. Aqua Guard Water Damage keeps trucks staged around Mill 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 Mill 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.
Every technician on our Mill Valley 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.
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.
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.
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 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.
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.
Our sewage cleanup protocol follows IICRC S500 contamination standards, isolating the affected area, removing unsalvageable materials, and disinfecting every surface that had contact with blackwater.
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.
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.



A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
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.
We set drying equipment based on the specific moisture readings taken during assessment, not a generic placement pattern.
Once moisture readings confirm the structure is dry, we hand you documentation and move into any needed reconstruction.
We operate under proper licensing and insurance in every market we serve, with documentation available on request.
A crew close by isn't a marketing line — it's the difference between drying equipment running in an hour versus waiting half a day.
We'd rather explain the cost clearly upfront than have that conversation after the job is already underway.
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.

Coverage isn't limited to the city center — our Mill Valley routes extend out to the surrounding suburbs so outlying addresses aren't treated as an afterthought.

"I called in a panic at 11pm and someone actually picked up. The tech here in Mill Valley had air movers set up before midnight and explained exactly what they were doing and why."
James R., Mill Valley"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., Mill 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., Mill Valley"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., Mill Valley"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., Mill Valley"Our commercial unit flooded overnight and they had industrial equipment running before our staff arrived for the morning shift."
Angela F., Mill 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., Mill Valley"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."
