Aqua Guard Water Damage has spent years pulling water out of Mercer Island basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which Mercer Island 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 Mercer Island, 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.
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.
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.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Paint that bubbles or peels away from a wall, especially near baseboards, usually means moisture is pushing through from behind rather than a simple application problem.
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.
We treat Water Damage Repair as one continuous job rather than a series of handoffs — the crew that extracts the water is accountable for the drying results, and the drying results determine what reconstruction is actually needed.
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.
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.
The same team that documented the damage and dried the structure hands off directly to reconstruction, which keeps the whole timeline shorter and the paperwork simpler.
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.



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.
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.
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.
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.

"The team here in Mercer Island treated our emergency like it actually mattered, not like another ticket in a queue, and the drying documentation they left us was thorough enough to hand straight to our insurer."
James R., Mercer Island"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., 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"Fast response, clear pricing, and they coordinated directly with my insurance adjuster which saved me a huge headache during a stressful week."
Priya S., Mercer Island"Drying logs were shared with us daily so we always knew exactly where the job stood, not just a vague 'it's drying' update."
Carlos V., Mercer Island"Our commercial unit flooded overnight and they had industrial equipment running before our staff arrived for the morning shift."
Angela F., Mercer Island"A cracked supply line under the kitchen sink went unnoticed for days and by the time we called, the subfloor was saturated. The crew pulled the damaged material and had drying equipment running within the hour."
Tyrone B., Mercer Island"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."
