Slab Leak Repair in Ontario, CA

A warm spot on the floor, the sound of running water, or a sudden jump in the water bill can all point to a leak under the slab. We find and repair slab leaks in Ontario homes. Ontario is a short drive west on the I-10 from our Rialto shop.

We are a small, local outfit, not a franchise. Drain Edge Rooter runs out of 619 E South St in Rialto, holds C-36 license #1078977, and answers (909) 927-3194 24/7.

Local factors in Ontario

Ontario is really two cities in one when it comes to plumbing. North of the 60, around Euclid Avenue’s wide median and the older blocks near Holt Boulevard, many homes went up before or shortly after World War II. South of Riverside Drive, Ontario Ranch is still being built out, and those homes have modern plastic and PEX piping.

Copper lines under older Ontario slabs can wear thin from hard water and from rubbing against concrete or rebar. Ontario’s water is a blend of local groundwater and imported supply, and like most of the Inland Empire it runs hard, so scale build-up on valves, heaters and fixtures is something we see often.

Parts of Ontario we cover

Between those two, there are a lot of 1970s and 1980s tracts near Mountain Avenue, Vineyard Avenue and the Creekside area, where the original copper and drain lines are now decades old. When we pull up to an Ontario address, the age of the street usually tells us what we are likely to find before we open a single cleanout.

College Park and the neighborhoods north of the 10
streets off Holt Boulevard and Mission Boulevard
Creekside and the tracts near Mountain Avenue

Working in Ontario

Getting to Ontario is easy for us. From Rialto we take the 10 west, and from there Euclid Avenue, Grove Avenue, Vineyard Avenue and Archibald Avenue get us to most of the city quickly. Ontario Ranch, down past Riverside Drive, is a longer drive south, but it is still regular territory for us.

A lot of Ontario’s older homes near downtown have been remodeled more than once, so the plumbing in the walls may not match the plumbing at the fixtures. In the newer Ontario Ranch tracts, many homes are part of HOAs, and we work around community rules on parking, access and work hours.

Ontario also has a lot of rentals, duplexes and small commercial buildings along Holt Boulevard and Mission Boulevard. Property managers and landlords call us for tenant calls, and we keep them in the loop with what we found and what it cost.

What happens when you call

You talk to our team directly. We ask what you are seeing, how long it has been going on and whether it is getting worse. If water is causing damage right now, we walk you through shutting it off. On site, we find the cause, show you what we found, and go over the options and the price before any work starts. When we finish, we test everything with you.

Slab Leak Repair FAQ for Ontario

Does insurance cover slab leaks?

Many policies cover some of the damage or access costs. Check your policy; we can provide documentation.

What about drain leaks under the slab?

Drain lines can leak too. A camera inspection shows their condition.

Do you have to break up my floor?

Not always. Sometimes a small opening for a spot repair works; sometimes rerouting the line above the slab avoids opening the floor at all.

Are you available 24 hours?

Yes. Call (909) 927-3194 anytime.

Do you serve all of Ontario?

Yes. Ontario is a short drive west on the I-10 from our Rialto shop, and we cover Downtown Ontario along Euclid Avenue, Creekside and the tracts near Mountain Avenue, homes near Ontario International Airport and Ontario Mills and the rest of the city, 24 hours a day.
