Who We Are

Licensed, Local, and Ready 24/7

Aqua Guard Water Damage built its Ontario 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 Ontario, 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.

Problem Awareness

Signs You Need Basement Flooding Right Now

Water Stains or Discoloration

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 Odor That Won't Air Out

A persistent musty smell in a basement or bathroom usually means microbial growth has already started somewhere you can't see, often inside wall cavities or under flooring. Air fresheners will mask it temporarily but won't touch the actual source.

Warped or Buckling Flooring

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.

Rising Water Bill With No Clear Cause

A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.

Peeling Paint or Bubbling Wallpaper

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.

Visible Mold Growth

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 Core Services

Full-Service Basement Flooding, Start to Finish

Our Basement Flooding 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.

Emergency Water Extraction

Our crews arrive with truck-mount extraction units capable of pulling thousands of gallons per hour, using moisture meters to classify the water as Category 1, 2, or 3 before drying even starts.

Structural Drying & Dehumidification

Equipment placement isn't guesswork; it's calculated from psychrometric readings taken at the start of the job and adjusted daily as conditions change.

Sewage & Contaminated Water Cleanup

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.

Mold Prevention & Remediation

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.

Reconstruction & Repairs

We handle everything from replacing water-damaged drywall and insulation to refinishing floors, so the property is restored to pre-loss condition under one contract instead of three.

Content Cleaning & Pack-Out

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.

Our Process

How Our Basement Flooding Response Works

Call Dispatch

A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.

Rapid On-Site Assessment

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 & Drying

Extraction and drying run as one continuous process rather than two separate visits, which keeps the timeline tighter.

Verification & Repairs

Once moisture readings confirm the structure is dry, we hand you documentation and move into any needed reconstruction.

Why Choose Us

The Aqua Guard Water Damage Standard

Licensed & Insured

Insurance and licensing aren't just paperwork here — they're what let us stand behind the work if something doesn't go as planned.

Fast Local Dispatch

Local staging means shorter drive times, which matters most in the first hour after a water loss.

Upfront Flat-Rate Pricing

You get a written estimate before work begins, not a surprise invoice after the drying equipment is already running.

Satisfaction Guarantee

If a drying target isn't met on the first pass, we extend equipment placement at no extra charge until moisture readings confirm the structure is dry.

The Aqua Guard Water Damage Guarantee

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.

Customer Reviews

What Our Customers Say

★★★★★

"A pipe burst behind our water heater and the crew here in Ontario had extraction units running within 40 minutes of my call. They walked me through the moisture readings every day until it was fully dry."

James R., Ontario
★★★★★

"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., Ontario
★★★★★

"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., Ontario
★★★★★

"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."

Priya S., Ontario
★★★★★

"We had a slow leak we didn't notice for weeks and the crew found moisture in places we never would have checked using thermal imaging."

Carlos V., Ontario
★★★★★

"Coordinating a commercial job around our operating hours could have been a nightmare, but their crew worked around our schedule without us having to ask twice."

Angela F., Ontario
★★★★★

"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., Ontario
★★★★★

"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."

FAQ

Frequently Asked Questions

How fast can a Basement Flooding technician arrive in Ontario, CA?
Our Ontario crews typically reach an active water loss in under an hour, since trucks are staged locally rather than dispatched from a distant office.
What's the difference between clean water and gray water damage?
Category 1 water is sanitary at the source, while Category 2 water has picked up detergents, food particles, or other contaminants that call for more careful handling during extraction.
Do you move or store damaged belongings during the drying process?
We separate and stage contents away from the wet zone during extraction and drying, then help coordinate cleaning for anything that can be salvaged.
What information should I have ready when I call?
It helps to know roughly where the water is coming from, how long it's been an issue, and whether the water looks clean or contaminated, though we can walk you through it if you're not sure.
Do you provide upfront pricing?
We quote upfront based on the assessment, and that quoted number is what you pay regardless of how long drying takes.
What emergency services are available?
Our emergency line covers extraction, drying, contaminated water cleanup, and the reconstruction that follows, all coordinated by one crew.
Do you work directly with insurance companies?
We provide the documentation adjusters expect, including moisture readings and photo evidence, and we're happy to speak with your insurance company directly.
How do you classify contaminated water?
Water gets classified on arrival using IICRC S500 guidelines, which determines whether standard extraction or full contamination protocols apply.
How long does structural drying typically take?
Drying time depends on the materials affected and how long they were wet, but we track it with daily moisture logs instead of estimating blindly.
Will you need to remove drywall or flooring?
We remove only what moisture readings and contamination levels require, not as a default step, to keep your repair costs down.
Can you help prevent mold after a leak?
Yes, antimicrobial treatment is applied to affected porous materials as part of the standard drying process, especially after 48 hours of exposure.
Do you offer service outside normal business hours?
Yes, emergencies are handled around the clock — the same crew structure that answers at 2pm answers at 2am.
What should I do while waiting for the crew to arrive?
Turn off the water supply if you can locate it safely, and stay out of rooms with standing water near electrical outlets or panels.
Do you handle commercial properties?
Commercial water damage gets the same extraction and drying protocol as residential work, scaled up with larger equipment as needed.
Is a small leak worth calling about?
A small leak left untreated is exactly how hidden mold problems start, so it's worth a moisture check even if the visible damage looks minor.
