Which parts of Orange
Old Towne's historic homes sit on raised foundations, so they don't get slab leaks except under later additions. The slab homes are in the surrounding post-war neighbourhoods, and further east in homes built through the 1970s. Those 1970s homes are now old enough that slab leaks are becoming more common there too.
Signs Orange owners report
- A warm strip of floor between the garage and the kitchen
- Cracked or hollow-sounding tile in a hallway
- Carpet tack strip rusting along an interior wall
- The water heater firing when no one has used hot water
- A meter that keeps creeping overnight
Cold-side leaks take longer
Hot-side slab leaks are quick to find with a thermal camera. Cold-side leaks don't warm the floor, so the plumber relies on pressure tests and acoustic listening, and sometimes tracer gas. If the pressure test shows the cold side is leaking, expect the locate to land toward the top of the price range.
After the locate
You'll get a choice between opening the slab at the leak and rerouting the line overhead. In homes where the slab has been repaired before, a reroute or a hot-side repipe is often the better long-term call. If your homeowners policy covers access costs, call the insurer before the floor is opened. See what leak detection costs for typical figures.
1970s homes in east Orange
Neighbourhoods built in the 1970s toward the eastern hills were long thought of as too new for slab leaks, but their copper is now around fifty years old. Many of these homes are larger and some are two-storey, so the hot line under the slab may run a long way from the heater to a kitchen or family room at the back.
For those homes, a reroute may need to go through the garage ceiling, a soffit or an interior closet rather than a straightforward attic run. Ask the plumber to walk you through the route and where access holes will be. If a second leak has already happened in a home of this age, it's worth getting a price for repiping the hot side at the same time.
Questions people ask
Do Old Towne Orange homes get slab leaks?+
Rarely, because most are on raised foundations. Slab-on-grade additions at the back are the exception.
Why is my cold-side leak more expensive to find?+
It doesn't show up on a thermal camera, so it takes more listening and testing, and sometimes tracer gas.
Can I keep using water while I wait?+
If it's a hot-side leak, close the heater's cold inlet and use cold water normally. For a cold-side leak, close the main when you're not using water.
