Slab Leak Detection & Repair in Corona
Corona slab leak detection and repair for 1980s-2000s slab homes, including polybutylene. Use your new smart meter to spot leaks, then call us 24/7.
Corona's oldest homes sit in and around the Grand Boulevard circle, but most of the city was built from the late 1970s on, with South Corona, Eagle Glen and Dos Lagos filling in through the 2000s. Those newer neighborhoods are largely slab-on-grade, and many 1980s and early-1990s houses have copper under the floor or, in some cases, polybutylene.
Corona has also been upgrading its water meters citywide, which gives many homeowners a new way to spot hidden leaks early. Between better meter data and careful detection, most slab leaks here can be found without guesswork or a jackhammer.

What's different about slab leak detection & repair in Corona
1980s and early-1990s tracts
Homes from this era are reaching the age when copper under the slab can develop pinhole leaks, especially on hot lines that flex against concrete. Some were plumbed with polybutylene, a gray plastic pipe often stamped PB2110 that is prone to sudden failures. Knowing which material you have shapes the repair.
Corona's smart meter rollout
The City of Corona Utilities Department has been replacing meters citywide with advanced meters. Once yours is installed, the MyAccount.CoronaCA.gov portal can show hourly use and send leak alerts. Hourly numbers that never drop to zero overnight are a strong hint that water is escaping somewhere.
Older homes around Grand Boulevard
In the historic core, homes often have galvanized lines and decades of piecemeal repairs. A leak in one of these houses may be in old pipe inside a wall rather than under concrete, so we trace the system before calling it a slab leak.
Hillside pressure
Neighborhoods like Sierra del Oro and Corona Hills climb the slopes, and homes on hills depend on a working pressure regulator. California's plumbing code requires one when static pressure exceeds 80 psi. When a regulator fails, every joint in the house feels it, including the buried ones.
Signs it's time to call
- Hourly use in the city's portal that never reaches zero, even at 4 a.m.
- A leak alert from your new Corona meter
- A tile floor that feels warmer in one spot than the rest of the room
- The sound of running water near a wall or floor when everything is off
- Gray plastic supply pipe at the water heater along with a rising bill
How we handle it in Corona
We check the meter, isolate the hot and cold lines, and pressure-test each. Acoustic and thermal tools then narrow the leak to a small area. For a single leak in copper that's otherwise sound, a spot repair can be the least expensive fix, though the rest of the old pipe stays in the slab. A reroute moves that line into the walls or attic and leaves your flooring alone. If you have polybutylene or repeat leaks, repiping is usually the way to stop paying for the same problem twice.
Water that has spread under flooring or into walls needs proper drying. Our IICRC-certified team does that work - see water damage restoration in Corona - and records it in detail for the insurance adjuster. A common pattern is coverage for the damage the water caused but not for fixing the pipe, so check your coverage.
Corona questions, answered
Corona replaced my water meter. How do I use it to check for a leak?+
Log in at MyAccount.CoronaCA.gov and look at your hourly use overnight, when the house should be quiet. A steady flow every hour with no breaks suggests a leak. You can also set custom alerts so you hear about unusual use right away instead of on your next bill.
Is polybutylene common in Corona homes?+
It was used in some homes from roughly the late '70s through the mid-'90s, the same era as many Corona tracts. Check for gray flexible pipe at the water heater or under sinks. If you find it, repiping is usually a better investment than repairing one leak at a time.
Can you fix a slab leak without jackhammering my floor?+
Often, yes. A reroute abandons the leaking line and runs new pipe through walls or the attic, so the slab stays intact. When a spot repair is the better call, accurate detection keeps the opening small. Our slab leak guide explains both.
