Frequently Asked Questions

What are signs of a slab leak in a Cotati 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. Cotati homes built in the 1960s era with corroded galvanized pipes in mid-century homes, aging HVAC systems, and main sewer lines with root intrusion are particularly prone to slab leaks.
How do you detect leaks without tearing up my Cotati 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 Cotati 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 Cotati home individually to recommend the best approach.
How long does leak detection take in Cotati?
An electronic leak detection visit takes 1–3 hours. We can usually schedule same-day or next-day for Cotati locations.
