From a slow leak behind the drywall to a full basement flood, Alton property owners call Aqua Guard Water Damage because we show up with the right gear the first time — no guesswork, no upsells at the door.

Aqua Guard Water Damage has spent years pulling water out of Alton basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which Alton 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 Alton, 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 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.
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.
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.
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 Structural Drying 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.
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.
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.



You call +1-844-234-5373 and speak with a live dispatcher, not a voicemail system — we ask a few quick questions about the source and severity so the crew arrives prepared.
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.
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.
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.
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 +1-844-234-5373Our Alton coverage area spans 3809, with trucks positioned to reach any address in the service radius quickly.
Coverage isn't limited to the city center — our Alton routes extend out to the surrounding suburbs so outlying addresses aren't treated as an afterthought.

"The team here in Alton 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., Alton"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., Alton"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., Alton"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., Alton"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., Alton"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., Alton"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., Alton"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."
