Avoid further issues and call Big Blue Plumbing to schedule your inspection. Our slab leak repair team serves Oakland and nearby communities, providing prompt support when you need it most.

Repairing Slab Leaks With Your Radiant Heating System
Many historic homes in Oakland feature radiant heating systems that were considered efficient ways to warm a house. At Big Blue Plumbing, we also provide installation of hydronic radiant heating systems, an upgrade from the original copper piping within slabs. When servicing or repairing radiant heat systems, we ensure proper purging techniques to maintain safety and performance.
More than 90% of the radiant heating calls we handle relate to air trapped in the system. We thoroughly remove any air before restarting the boiler, which helps prevent further problems. If you own an older radiant heating system, schedule an evaluation if you notice anything unusual.
We have extensive experience working with radiant heating systems unique to East Bay architecture. In many Oakland homes and businesses, original copper or steel pipes require careful attention to avoid further disturbance during repairs. Ground movement and micro-seismic activity in the Bay Area put additional stress on these systems, so we stay alert for signs of leaks or inefficiency that other providers might miss. During an assessment, we inspect fixtures, shutoff valves, and pressure controls for subtle issues. This proactive approach protects your comfort and supports the reliability of your heating and plumbing.
How to Spot a Slab Leak
A slab leak stems from the copper pipes installed within concrete slabs for radiant heating. Often located underground, these pipes may be on either the pressure or drainage side of the foundation. With few surface signs, slab leaks can go unnoticed and cause water to leak for long periods before anyone discovers the problem. If you notice any of the following, you may have a slab leak beneath your foundation:
- Unexplained spikes in your water bill
- Sounds of water running when no fixtures are in use
- Changes in water meter readings or pump activity
- Foundation cracks
- Mildew or musty odors
- Wet spots or bubbling water through floor cracks
Allowing a slab leak to persist can cause lasting harm to your home's foundation. Schedule an inspection with our team to determine if your property shows any warning signs of a slab leak.
