Who We Are

Licensed, Local, and Ready 24/7

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

Water Stains or Discoloration

Yellow-brown rings on your ceiling or walls almost always mean water has been sitting behind the surface longer than you think, and the drywall paper backing is likely already feeding mold growth. Waiting to see if the stain spreads only gives moisture more time to travel further into the structure.

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

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.

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

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

Full-Service Basement Flooding, Start to Finish

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.

Emergency Water Extraction

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.

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

Blackwater jobs get treated with extra caution, since porous materials that touched contaminated water almost always need to be removed rather than dried in place.

Mold Prevention & Remediation

Once structural drying is underway, we apply antimicrobial treatments to studs, subfloor, and other porous surfaces to stop mold colonies before they establish, especially in areas that stayed wet more than 48 hours.

Reconstruction & Repairs

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.

Content Cleaning & Pack-Out

Specialized cleaning techniques can often save upholstery, electronics, and documents that look like a total loss at first glance, which keeps out-of-pocket replacement costs down.

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

Final verification is where a lot of shortcuts get taken industry-wide — we treat it as mandatory, not optional.

Why Choose Us

What Makes Aqua Guard Water Damage Different

Licensed & Insured

We operate under proper licensing and insurance in every market we serve, with documentation available on request.

Fast Local Dispatch

Trucks are staged regionally so a crew can typically reach you well before a national chain's call center even finishes your intake form.

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

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.

The Aqua Guard Water Damage Guarantee

We'd rather run drying equipment an extra day at our own cost than close out a job with a moisture reading we're not confident in.

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 San Jose 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., San Jose
★★★★★

"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., San Jose
★★★★★

"They didn't cut corners on the contaminated water cleanup even though it would have been faster to skip the sanitization step — that mattered to me given we have young kids in the house."

Marcus T., San Jose
★★★★★

"Fast response, clear pricing, and they coordinated directly with my insurance adjuster which saved me a huge headache during a stressful week."

Priya S., San Jose
★★★★★

"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., San Jose
★★★★★

"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."

Angela F., San Jose
★★★★★

"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., San Jose
★★★★★

"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."

Wendy K., San Jose
FAQ

Frequently Asked Questions

How fast can a Basement Flooding technician arrive in San Jose, CA?
Our San Jose 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?
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?
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?
We handle 24/7 emergency water extraction, structural drying, sewage cleanup, mold prevention, and reconstruction under one call.
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?
We follow IICRC standards, classifying water as Category 1 (clean), Category 2 (gray), or Category 3 (black/sewage) before choosing extraction and PPE protocols.
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?
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?
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?
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?
Yes, we service both residential and commercial properties, with equipment scaled to the size of the loss.
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.
