From a slow leak behind the drywall to a full basement flood, Corona 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 built its Corona 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.
We answer our own phones around the clock in Corona, 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.
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.

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.
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.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Wallpaper that lifts at the seams after being fine for years is often a sign that humidity or a slow leak has changed the moisture level inside that wall.
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.
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.
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.
Furniture, documents, and electronics affected by water intrusion get assessed on-site, with salvageable items cleaned and stored while unsalvageable items are documented for your claim.



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.
Extraction and drying run as one continuous process rather than two separate visits, which keeps the timeline tighter.
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.
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.
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.
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 +1-844-833-1325Whether your address falls in 92882 92880 92881 92879 92877 92878 92883 or one of the neighboring zip codes we cover, the same crew and the same response standard applies.
We track call volume by zip code across Corona to keep crew staffing matched to where emergencies actually happen most often.

"I called in a panic at 11pm and someone actually picked up. The tech here in Corona had air movers set up before midnight and explained exactly what they were doing and why."
James R., Corona"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., Corona"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., Corona"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., Corona"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., Corona"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., Corona"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., Corona"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."
