Water Leak Repair
A small leak can damage cabinets, flooring, and walls when it's ignored. This page explains the signs you may notice, why it pays to have them checked, and how to request help in Oakland and the Bay Area.
Water leaks can turn into bigger problems
A small water leak might not seem like a big deal at first. But moisture under a sink, around a toilet, or behind a wall can damage cabinets, flooring, and lead to other costly problems. If you've noticed dripping pipes, unexplained dampness, or water stains, it's a good idea to have it checked before it gets worse.

Questions about leaks
What should I do if I find a leaking pipe?
Stay safe first. Don't enter a flooded area with electrical equipment or touch energized appliances. If you can safely reach your main water shutoff, turn off the water. Then call us at (510) 258-3252 and describe what you see.
How can I tell if I have a plumbing leak?
Common signs include damp stains on ceilings, walls, or cabinets, the sound of water running when nothing is on, a water bill that rises without a change in your usage, musty odors, or low pressure at a fixture. Any of these is a good reason to ask for an assessment.
Is a small water leak a serious problem?
A small leak can damage cabinets, flooring, and walls over time, and raise your water bill. It's worth having any leak checked before it gets worse. Describe what you see and where it is, and we can talk through next steps.
What should I do if water is leaking under my sink?
Clear the area under the sink so you can see the source if it's safe. If you can safely reach the shutoff valve for that fixture, turn it off. Put a bucket or towel under the leak if it helps, then call us and describe what you see and when it started.
