Whether it's a slow leak that's been eating your subfloor for weeks or a flooded basement at 2am, our Onyx crews are already moving. We dispatch Onyx units carrying industrial extraction pumps, air movers, and commercial dehumidifiers already loaded on the truck.
Too many Onyx, CA families have called a big national number only to get bounced through hold music before a random subcontractor shows up hours later, so Hirex Water Damage built its Onyx operation differently. Every technician on our Onyx roster is a Hirex Water Damage employee, not a gig-app contractor pulled from a random directory.
Our senior technicians are IICRC-certified and have worked everything from a clean supply-line break to a full sewage backup, so Mold Remediation in Onyx isn't a side service we tacked on — it's the reason the company exists. We carry full general liability coverage and are licensed to operate throughout Onyx, CA, so you're protected from the moment our truck pulls into the driveway.
Our Onyx, CA-based equipment cache means drying gear is already close by, not stuck in a truck three states away.
Anyone in Onyx who has had a supply line fail overnight knows the real cost isn't the leak itself, it's how long the standing water sits before someone with the right equipment arrives. That's the gap Hirex Water Damage was built to close, one Onyx call at a time.
Not every leak announces itself with a flooded floor. A lot of the worst damage we see in Onyx started small and got ignored for weeks. Here's what tells us a property needs professional attention rather than a mop and a fan:
If you're nodding along to any of these, get ahead of it now rather than later — our Onyx dispatcher will give you an honest read on urgency, not a sales pitch.
From a single soaked bedroom to a commercial building with three flooded floors, our Onyx teams are equipped to scale up or down — nothing gets a cookie-cutter response.
Our Onyx units run truck-mount extraction pumps that pull thousands of gallons per hour, cutting standing-water time from days to hours. Every extraction job includes moisture mapping so we know exactly which materials are still holding water once the visible flooding is gone.
Our drying plans use moisture meters and thermal imaging to target air movers exactly where hidden moisture is trapped, with daily drying logs so you can see the numbers improving, not just take our word for it.
For families in Onyx, this covers flood-cut drywall removal, subfloor evaluation, and packing out salvageable belongings for cleaning, with clear photo documentation at every stage for your insurance claim.
Multi-unit and commercial Onyx properties get their own project manager plus enough drying equipment to cover the real square footage, not a token setup — we know a flooded lobby or a leaking unit above tenants below has to move fast.
When a Onyx job involves sewage backup, our team suits up in full PPE, applies EPA-registered antimicrobials, and safely disposes of porous materials that can't be saved.
On top of standard drying, our Onyx crews treat affected materials to reduce mold risk and will be upfront if a section needs specialist remediation.
You get a written estimate before any equipment runs, not a mystery total handed to you after the fact.
Our Onyx, CA warehouse keeps drying equipment close, which typically puts a Onyx tech at your door inside an hour.
Our paperwork is built to match what adjusters expect, and we'll speak with your insurer directly on your behalf.
We don't call a job finished until the moisture meter agrees, and if it doesn't, we return at no additional cost.
Tell our Onyx dispatcher what's happening — we'll ask a few quick questions to send the right equipment on the first trip.
The closest available technician is routed to your Onyx property with equipment staged and ready.
We remove standing water first, then map moisture and position air movers and dehumidifiers based on the readings.
Daily moisture checks continue until every affected material reads dry, and you get a complete report at the end.
We measure moisture with instruments, not guesswork, and we won't sign off on a Onyx job until those readings match the dry standard for the materials involved. If a callback shows lingering moisture within 30 days of a completed job, we return and correct it at no additional charge.
That's not a marketing line — it's written into every Onyx work order we issue. If a second visit is ever needed, it comes from the same crew that handled the original job whenever scheduling allows, since they already know the property and the readings we started from.

Drying time varies with material and how quickly extraction started, but 3 to 5 days is typical for most Onyx jobs.
