Who We Are

Licensed, Local, and Ready 24/7

Our San Mateo technicians hold IICRC water restoration certifications and carry that training into every job, from a Category 1 clean-water leak to a Category 3 sewage backup. We're not a call center routing you to a random subcontractor; we're the crew that shows up.

Every technician on our San Mateo 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.

Problem Awareness

Signs You Need Water Damage Repair Right Now

Water Stains or Discoloration

Ceiling stains near a bathroom or kitchen almost always trace back to a plumbing failure rather than a roof leak, which means the source is often closer and easier to fix than homeowners assume.

Musty Odor That Won't Air Out

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.

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

If your usage climbs but nothing in your household routine changed, a hidden leak behind a wall or under the foundation is worth investigating immediately, since slab leaks rarely announce themselves any other way.

Peeling Paint or Bubbling Wallpaper

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.

Visible Mold Growth

Any visible mold, even a small patch in a corner or along a baseboard, means conditions behind that surface have supported growth for a while and the moisture source needs to be found, not just the mold wiped away.

Our Core Services

Comprehensive Water Damage Repair You Can Count On

Our Water Damage Repair 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

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.

Sewage & Contaminated Water Cleanup

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.

Mold Prevention & Remediation

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.

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

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.

How Our Water Damage Repair Response Works

Call Dispatch

You call +1-844-578-1604 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.

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

Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.

Verification & Repairs

We re-test every affected area before calling a job complete, then coordinate repairs so you're not left with an open punch list.

Why Choose Us

Why Property Owners Choose Aqua Guard Water Damage

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

We stand behind every job with a documented re-inspection before we consider the work complete.

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.

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.

Customer Reviews

What Our Customers Say

★★★★★

"The team here in San Mateo 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., San Mateo
★★★★★

"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., San Mateo
★★★★★

"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., San Mateo
★★★★★

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

Priya S., San Mateo
★★★★★

"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., San Mateo
★★★★★

"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., San Mateo
★★★★★

"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., San Mateo
★★★★★

"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."

FAQ

Frequently Asked Questions

How fast can a Water Damage Repair technician arrive in San Mateo, CA?▼
Average arrival time in San Mateo is well under 60 minutes for active emergencies, though exact timing depends on traffic and current call volume.
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?▼
Yes, we can relocate salvageable contents out of the affected area so drying equipment has clear access and your belongings aren't sitting in a wet environment.
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?▼
Yes, every job starts with a written flat-rate estimate before any equipment is turned on, so there are no surprise line items later.
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?▼
Yes, we document every job with photos and moisture logs formatted for insurance claims and can communicate directly with your adjuster.
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?▼
Most residential drying cycles run three to five days, verified with daily moisture readings rather than a fixed calendar guess.
Will you need to remove drywall or flooring?▼
Only where materials can't be safely dried and sanitized — our goal is to save as much of the original structure as possible.
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?▼
Our dispatch line runs 24 hours a day, 7 days a week, including holidays, because water damage doesn't wait for business hours.
What should I do while waiting for the crew to arrive?▼
If it's safe, shut off the water source, move valuables to a dry area, and avoid using electrical outlets near standing water until we arrive.
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.
