Whether it's a slow leak that's been eating your subfloor for weeks or a flooded basement at 2am, our Castro Valley crews are already moving. Hirex Water Damage sends licensed technicians straight to your Castro Valley address with extraction equipment already loaded and running.

We built our Castro Valley branch after hearing the same complaint over and over from Castro Valley, CA property owners — the "24/7" number that never actually answers. Every technician on our Castro Valley roster is a Hirex Water Damage employee, not a gig-app contractor pulled from a random directory.
Our crew leads carry IICRC water restoration certifications and have logged real hours on Category 1, 2, and 3 losses, so Water Damage Repair in Castro Valley 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 Castro Valley, CA, so you're protected from the moment our truck pulls into the driveway.
Because our equipment lives in a Castro Valley, CA warehouse rather than out of state, we're not waiting on a supply run before we can start extraction.
Ask any Castro Valley 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 Castro Valley call at a time.

Water damage doesn't always look dramatic at first — some of the costliest Castro Valley jobs we've handled began as a small, easy-to-miss problem. Here's what tells us a property needs professional attention rather than a mop and a fan:
Recognizing one of these signs early is the difference between a contained repair and a gutted room, so call our Castro Valley team and get a straight answer on how urgent it is.
We size the Castro Valley 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 Castro Valley 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.
Once water is out, we bring in commercial air movers and LGR dehumidifiers, positioned using psychrometric readings rather than guesswork, with daily drying logs so you can see the numbers improving, not just take our word for it.
For Castro Valley 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 Castro Valley 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 Castro Valley 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 Castro Valley crews treat affected materials to reduce mold risk and will be upfront if a section needs specialist remediation.

Every Castro Valley estimate is written and explained before work begins — no vague "we'll see how it goes" pricing.

We don't call a job finished until the moisture meter agrees, and if it doesn't, we return at no additional cost.
Our Castro Valley team asks a handful of targeted questions so the truck that shows up already has the right gear loaded.
A licensed technician heads to your Castro Valley address with extraction and drying equipment already loaded.
Extraction happens immediately, followed by a moisture survey that tells us precisely where the drying equipment needs to go.
We re-check moisture levels daily until materials hit dry standard, then hand you full documentation for your records or your insurer.

Every Castro Valley job gets closed based on instrument readings, not a visual check, and we won't call it finished until the numbers say it's finished. If a callback shows lingering moisture within 30 days of a completed job, we return and correct it at no additional charge.
We put that guarantee directly on the Castro Valley work order, not just in an ad. We try to send the original technician back for any follow-up so you're not re-explaining the job to someone new.
