When a pipe bursts or a storm backs up your drain lines, waiting on hold is the last thing you can afford. Our Mercer Island-based crews carry moisture meters and truck-mount extraction equipment on every rig so the drying process starts the moment we knock on your door.

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.
Every technician on our Mercer Island 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.

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.
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.
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.
Our Mold Remediation 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.
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.
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.
Final verification is where a lot of shortcuts get taken industry-wide — we treat it as mandatory, not optional.
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.
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.
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.
That same standard applies whether it's a single flooded bathroom or a full commercial loss — the sign-off criteria don't change based on job size.
Call +1-844-234-5373Whether your address falls in 98040 or one of the neighboring zip codes we cover, the same crew and the same response standard applies.
Coverage isn't limited to the city center — our Mercer Island 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 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"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., Mercer Island"Every question I asked got a straight answer, even the ones about cost, which is rare after dealing with two other contractors who kept dodging the pricing conversation."
Priya S., Mercer Island"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., 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"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."
