Leak Detection & Repair in Sonoma & Marin Counties

A small leak can waste water, damage flooring, and lead to mold if it goes unnoticed. Integrity Plumbing finds and repairs leaks in homes and businesses across Sonoma and Marin Counties — from a dripping faucet to a hidden pipe leak in a wall, crawl space, or slab.

We start by listening to what you have noticed: a water stain, a sudden jump in the water bill, the sound of running water when everything is off, or a soft spot in the floor. Then we inspect the likely sources and trace the leak so we are repairing the right pipe, not just the stain it left behind. Once we find the source, we explain the repair in plain language, give you a free estimate, and complete the work to stop the leak and limit further damage.

Common leak jobs include faucet and supply-line drips, toilet leaks, water heater tank or connection leaks, damaged hose bibs, irrigation or hose-spigot leaks that quietly raise the water bill, and aging or corroded pipes. If a leak is tied to a larger piping problem, we will tell you whether a targeted repair is enough or whether a section of pipe should be replaced. We do not push work you do not need.

Hidden leaks are easy to miss in this area. Many homes have crawl spaces, older valves, or pipes in walls and ceilings. After winter storms, we also see leaks that only show up when the system is used more, or when a pipe that was barely holding on finally fails. If you have tried tightening a fitting or replacing a washer and the leak continues, it is time for a licensed plumber to open up the real source.

If you think you have a leak, shut off the water at the fixture or at the main valve if you can do so safely, then call or text (707) 241-3192. You can also request service at our contact page. The sooner a leak is stopped, the less damage you are likely to have to floors, cabinets, and drywall.
