Aqua Guard Water Damage has spent years pulling water out of San Leandro basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which San Leandro 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.
We answer our own phones around the clock in San Leandro, 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.
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.
Mold that returns after cleaning with bleach is a sign the underlying moisture source was never addressed, since surface cleaning does nothing for saturated material behind the wall.
Our Water Damage Repair 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.
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.
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.
We document the loss with photos and moisture readings before touching anything, which also protects your insurance claim.
We set drying equipment based on the specific moisture readings taken during assessment, not a generic placement pattern.
We re-test every affected area before calling a job complete, then coordinate repairs so you're not left with an open punch list.
We operate under proper licensing and insurance in every market we serve, with documentation available on request.
Local staging means shorter drive times, which matters most in the first hour after a water loss.
We'd rather explain the cost clearly upfront than have that conversation after the job is already underway.
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.
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.
Call +1-844-234-5373Whether your address falls in 94578 94579 94577 94622 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 Leandro to keep crew staffing matched to where emergencies actually happen most often.

"I called in a panic at 11pm and someone actually picked up. The tech here in San Leandro had air movers set up before midnight and explained exactly what they were doing and why."
James R., San Leandro"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 Leandro"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 Leandro"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 Leandro"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 Leandro"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 Leandro"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 Leandro"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."
