Pipes don't wait for daylight to fail, and our Diamond Bar dispatch team doesn't wait for morning to respond. Hirex Water Damage sends licensed technicians straight to your Diamond Bar address with extraction equipment already loaded and running.

Hirex Water Damage started because homeowners in Diamond Bar, 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 Diamond Bar 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 Basement Flooding in Diamond Bar isn't a side service we tacked on — it's the reason the company exists.
