Leak Detection & Slab Leak Repair in Corona, CA

Why Corona Is Seeing Slab Leaks Now

Corona has two plumbing profiles. The newer one, South Corona, Eagle Glen, Sierra Del Oro and the developments out toward Dos Lagos, went up largely in the 1990s and 2000s on concrete slabs, with copper supply lines run underneath. That copper is now 20 to 30 years old, which is the window when pinhole leaks start to appear.

Corona's water is part of the reason. The City of Corona's utilities department blends local groundwater with imported water, and an older city water quality report put hardness at about 290 milligrams per liter, very hard by any standard. Scale and decades of pressure wear at copper from the inside. A failed pressure regulator makes it worse: high static pressure stresses every pipe and fitting in the house, and regulator failures are a common Corona call.

The older core near downtown and along Sixth Street is different. Homes there go back to the early and mid twentieth century, and leaks are more often in aging galvanized lines inside walls or in the buried line from the meter to the house.

Signs of a Hidden Leak in a Corona Home

• A warm patch on a tile or concrete floor
• A water bill that climbs with no change in use
• The sound of water running when the house is quiet
• Damp or discolored baseboards, or a musty smell near one wall
• Low pressure at the hot side of several fixtures
• A soggy patch of yard between the street and the house

For a quick check, turn off every fixture, the irrigation and the ice maker, then look at the water meter in its box near the curb. If the small leak indicator is turning with nothing running, water is escaping. Homes in Temescal Valley, Coronita and Home Gardens are served by other water agencies, but the meter test works the same way.

Free Leak Detection in Corona: What Is Free and What Is Not

Searching for free leak detection in Corona usually turns up two different things. Pinpointing a leak under a slab with acoustic and thermal equipment is skilled work, and it is billed, typically at $150 to $500, with the price agreed before the equipment comes off the truck. What is free is the plumbing inspection included with any scheduled service call, a look at the supply lines, pressure regulator, water heater and drains that often turns up the first signs of trouble. See current specials.

What a paid detection visit includes: testing the hot and cold sides separately, thermal imaging for hot water leaks, acoustic listening to pinpoint the sound of water escaping under the slab, and a marked location on the floor with every repair option priced. You approve that price before anything is opened.

Repairing a Corona Slab Leak

Direct access

The slab is opened at the marked spot, the pipe is repaired and the concrete is patched. It suits a single leak in an accessible spot, with flooring repair as a separate cost.

Reroute

The failing line is abandoned in the slab and replaced through the walls or attic. In a 2000s Corona tract home, where the rest of the copper under the floor is the same age, a reroute often makes more sense than opening the floor. Reroutes inside city limits need a City of Corona permit; unincorporated addresses go through Riverside County.

Repipe

After two or three leaks, replacing all the supply lines is worth pricing against another repair. See pipe repair and repiping and slab leak repair.

What It Costs in Corona

Slab leak repairs by reroute or direct access are priced after the leak is located, with both options quoted. See leak repair prices and repiping and water line prices on the pricing page.
