Aqua Guard Water Damage built its Mercer Island 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.
Being local to Mercer Island means our estimators know the going rate for drywall and flooring replacement in your area, so the quote you get reflects your market instead of a national average that never quite matches your invoice.
We invest in ongoing training as drying standards and equipment evolve, rather than treating a technician's initial certification as the finish line.

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.
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.
Hardwood that's cupping at the edges or laminate that's separating at the seams is a classic sign of moisture intrusion from below, whether that's a slab leak or groundwater seepage. The longer it sits, the harder the flooring is to salvage.
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 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.
We prioritize extraction speed above everything else in the first hour, because every additional hour standing water sits raises the odds of secondary damage to subfloors and framing.
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.
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.
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.



A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
The assessment sets the entire plan — skipping it or rushing it is how jobs end up with hidden moisture pockets months later.
Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.
Once moisture readings confirm the structure is dry, we hand you documentation and move into any needed reconstruction.
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.
You get a written estimate before work begins, not a surprise invoice after the drying equipment is already running.
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.
We'd rather run drying equipment an extra day at our own cost than close out a job with a moisture reading we're not confident in.
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 Mercer Island had air movers set up before midnight and explained exactly what they were doing and why."
James R., Mercer Island"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., Mercer Island"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., Mercer Island"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., Mercer Island"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., Mercer Island"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., Mercer Island"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., Mercer Island"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."
