About our service in Ontario
Ontario is a major commercial hub of the Inland Empire, home to Ontario International Airport and a substantial industrial and logistics sector. The residential side ranges from historic homes in the downtown area to newer developments in the south and east.
Common water damage issues in Ontario homes
Downtown Ontario has a significant inventory of pre-1940s Craftsman and Spanish Revival homes with older plumbing systems, including galvanized steel supply lines that corrode from the inside out. South Ontario and Ontario Ranch have newer construction where PEX and PVC systems dominate. Both areas share common risks from water heater failures and washing machine supply line ruptures.
What we do in Ontario
Treadwell Restoration provides both phases of water damage response for Ontario homeowners and businesses:
- Water Damage Mitigation & Cleanup — Stop the damage. Dry the structure. Prevent what comes next.
- Reconstruction & Restoration — Rebuild what the water took. Match what was there before.
- Mold Assessment & Prevention — Stop mold before it starts. Address it if it's already there.
- Insurance Claims Coordination — We speak insurance so you don't have to.
Why Ontario homeowners call Treadwell
We're local. We know Ontariohousing stock, we know the neighborhoods, and we know the quirks of building in this part of the Inland Empire. When you call, you're not getting routed to a national dispatch center — you're getting the same team that will be at your door.
Our background is 25+ years of general contracting, which means we can handle reconstruction in-house. If you want one company for the entire process — from water extraction through final paint — we can do that. If you only need the mitigation phase or only need reconstruction after another company did the cleanup, that's also fine.
