Frequently Asked Questions

What are signs of a slab leak in a Sonoma home?

Signs include unexplained water bill spikes, warm spots on floors, sound of running water when fixtures are off, and cracks in flooring or walls. Sonoma homes built in the 1850s era with historic clay sewer pipes prone to root intrusion, aging Victorian-era supply lines, and radiant heating systems in older properties are particularly prone to slab leaks.

How do you detect leaks without tearing up my Sonoma home?

We use electronic acoustic listening devices that detect the specific sound of water escaping under pressure through pipe walls. This pinpoints the leak location before any demolition.

Can you fix a slab leak in Sonoma without breaking up the floor?

In many cases yes. Pipe rerouting — running new pipe through walls or ceiling above the slab — avoids concrete demolition entirely. We assess each Sonoma home individually to recommend the best approach.

How long does leak detection take in Sonoma?

An electronic leak detection visit takes 1–3 hours. We can usually schedule same-day or next-day for Sonoma locations.
