Whether it's a slow drip that finally gave out or a sudden flood at midnight, Altadena residents call one number and get a real answer. Our Altadena-based teams roll out with extraction and drying gear already loaded, not scrambling to gather it after the call.


We built Hirex Water Damage's Altadena operation after hearing the same complaint over and over: the "24/7" number that never actually answers when it matters. Every technician you'll meet is a direct Hirex Water Damage employee, not a subcontractor pulled from an app.
Our lead technicians hold IICRC water restoration certification and have worked jobs ranging from a single soaked bedroom to a fully flooded commercial floor, which is why Flood Damage Cleanup in Altadena is treated as a specialty, not a side offering. We carry full liability coverage and hold active licensing to operate throughout Altadena, CA.
Because our gear is staged locally rather than shipped in, Altadena response times run well ahead of a typical national franchise.
Ask any Altadena property manager who's dealt with an overnight pipe failure and they'll tell you the real cost isn't the leak itself — it's how long standing water sits before someone with the right equipment shows up. That gap between a fast, equipped response and a slow, improvised one is exactly what Hirex Water Damage was built to close.
Our Altadena technicians go through regular continuing education, because a method that was standard five years ago may not be the best option today.

Not every water problem looks dramatic — some of the costliest Altadena repairs began as a barely-noticeable issue. Here's what tells our team a Altadena property needs a professional look rather than a mop and a fan:
If you're nodding along, get ahead of it now — our Altadena dispatcher will tell you honestly whether it's urgent or something we can schedule.
From a single flooded closet to a three-story commercial building, our Altadena crews scale the response to match the actual damage. Every service below reflects a specific piece of equipment or protocol, not just a marketing category.
We arrive with submersible pumps and truck-mount extractors built to clear a flooded Altadena room before water soaks deeper into the subfloor. Moisture mapping follows every extraction so we know which materials are still holding water once the visible flooding is gone.
Once extraction wraps, commercial air movers and LGR dehumidifiers go to work based on psychrometric readings, not a flat per-room count, with daily logs so you can watch the numbers improve.
On the residential side in Altadena, we handle the flood cut, subfloor checks, and content pack-out so the home is ready for rebuild, with photo documentation at every stage for your insurance file.
Altadena businesses and property managers get a dedicated project lead, after-hours crews, and equipment scaled to square footage — a flooded lobby or a leaking unit above tenants has to move fast.

Our Altadena technicians take moisture readings at the start and end of every job, and the final number has to hit dry standard before we leave. If a callback within 30 days shows lingering moisture from the same loss, we return and correct it at no additional charge.
You'll find that exact guarantee printed on your Altadena paperwork, not only spoken over the phone. A repeat visit under this guarantee means picking up exactly where the last one left off, not starting from scratch.
A guarantee only means something if it's backed by documented numbers, which is why every Altadena job closes with instrument readings attached.
