Whether it's a slow leak that's been eating your subfloor for weeks or a flooded basement at 2am, our Union City crews are already moving. Our Union City-based teams arrive with truck-mount extractors, moisture meters, and drying gear staged and ready to go.

Hirex Water Damage started because homeowners in Union City, CA kept telling us the same story: a national hotline picked up, put them on hold, and then subcontracted the job out to whoever was cheapest and closest. Every technician on our Union City roster is a Hirex Water Damage employee, not a gig-app contractor pulled from a random directory.
Each lead tech holds an IICRC Water Restoration Technician certification and has personally handled clean-water, gray-water, and contaminated black-water losses, so Mold Remediation in Union City 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 Union City, CA, so you're protected from the moment our truck pulls into the driveway.
Because our equipment lives in a Union City, CA warehouse rather than out of state, we're not waiting on a supply run before we can start extraction.
Ask any Union City property manager who has dealt with a burst supply line at 3am — the difference between a crew that shows up ready and one still loading a truck at the shop is measured in gallons of water soaking into your subfloor. That's the gap Hirex Water Damage was built to close, one Union City call at a time.

Not every leak announces itself with a flooded floor. A lot of the worst damage we see in Union City 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 Union City dispatcher will give you an honest read on urgency, not a sales pitch.
We size the Union City response to the actual damage — a single-room extraction gets a two-person crew, a commercial loss gets the full fleet — nothing gets a cookie-cutter response.
We arrive with submersible pumps and truck-mount extractors that get standing water out of a Union City property before it soaks deeper into the subfloor. Every extraction job includes moisture mapping so we know exactly which materials are still holding water once the visible flooding is gone.
We place industrial dehumidifiers and air movers based on actual psychrometric calculations, not a standard equipment count per room, with daily drying logs so you can see the numbers improving, not just take our word for it.
For Union City homeowners, that means drywall removal at the flood cut line, subfloor assessment, and content pack-out for anything that can be saved, with clear photo documentation at every stage for your insurance claim.
For commercial Union City accounts, we assign a project lead, run crews after normal hours to reduce downtime, and bring equipment sized to the actual footprint — we know a flooded lobby or a leaking unit above tenants below has to move fast.
When a Union City 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.
We apply antimicrobial treatment during every Union City drying job specifically to head off mold before it starts, and we'll flag any area that needs deeper remediation.

You get a written estimate before any equipment runs, not a mystery total handed to you after the fact.
Our Union City, CA warehouse keeps drying equipment close, which typically puts a Union City tech at your door inside an hour.
We document everything with photos and moisture logs and work directly with your adjuster so you're not stuck translating restoration jargon.
Final moisture readings have to hit dry-standard before we consider a Union City job done, and getting there again is on us, not you.
Tell our Union City dispatcher what's happening — we'll ask a few quick questions to send the right equipment on the first trip.
Our nearest available Union City crew is dispatched immediately with truck-mount extraction gear on board.
Extraction happens immediately, followed by a moisture survey that tells us precisely where the drying equipment needs to go.
We don't close the file until the numbers confirm the structure is dry, and you leave with full photo and moisture documentation.

Our Union City technicians use moisture meters at the start and the end of every job, and the final number has to hit the dry standard before we leave. 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 Union City work order we issue. We try to send the original technician back for any follow-up so you're not re-explaining the job to someone new.
