When a pipe bursts or a storm backs up your drain lines, waiting on hold is the last thing you can afford. Our Costa Mesa-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 has spent years pulling water out of Costa Mesa basements, crawl spaces, and commercial units, and that hands-on history shows in how fast our crews assess a loss. We know which Costa Mesa 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 Costa Mesa, 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.
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.
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.
We treat Basement Flooding 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.
Category 3 blackwater intrusions require full PPE, controlled demolition of porous materials that can't be sanitized, and hospital-grade antimicrobial treatment before reconstruction begins.
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.
Once the structure tests dry, our reconstruction team handles drywall, insulation, flooring, and trim so you're not managing a second contractor after the restoration crew leaves.
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.



A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
We document the loss with photos and moisture readings before touching anything, which also protects your insurance claim.
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.
If our moisture readings don't hit a safe drying standard on schedule, we keep equipment on site at no additional cost until they do — that's the standard we hold ourselves to.
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 Costa Mesa coverage area spans 92626 92627 92628, with trucks positioned to reach any address in the service radius quickly.
Coverage isn't limited to the city center — our Costa Mesa routes extend out to the surrounding suburbs so outlying addresses aren't treated as an afterthought.

"The team here in Costa Mesa 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., Costa Mesa"What impressed me most was the daily moisture log — I could actually see the numbers improving instead of just being told to trust the process."
Denise M., Costa Mesa"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., Costa Mesa"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., Costa Mesa"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., Costa Mesa"Our commercial unit flooded overnight and they had industrial equipment running before our staff arrived for the morning shift."
Angela F., Costa Mesa"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., Costa Mesa"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."
Wendy K., Costa Mesa
