Aqua Guard Water Damage built its San Lorenzo 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 Lorenzo 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.

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.
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.
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 Water Removal 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.
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.
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.
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.
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.
Specialized cleaning techniques can often save upholstery, electronics, and documents that look like a total loss at first glance, which keeps out-of-pocket replacement costs down.



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.
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.
Insurance and licensing aren't just paperwork here — they're what let us stand behind the work if something doesn't go as planned.
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.
You get a written estimate before work begins, not a surprise invoice after the drying equipment is already running.
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.

"A pipe burst behind our water heater and the crew here in San Lorenzo had extraction units running within 40 minutes of my call. They walked me through the moisture readings every day until it was fully dry."
James R., San Lorenzo"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 Lorenzo"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 Lorenzo"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., San Lorenzo"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., San Lorenzo"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 Lorenzo"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 Lorenzo"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."
