What to do about water under your sink

Water under a kitchen or bathroom sink should be checked promptly. The description alone cannot identify the source, so focus on safely observing the leak and use the Leak Repair service path when you need professional help.

Start with a safe check

Move items away from the wet area, note whether water is still appearing, and observe where it first collects. If water continues, spreads, or cannot be controlled, contact a plumbing professional rather than taking apart connections yourself.

What to observe before calling

Check whether the water is appearing inside the cabinet, near the sink basin, or around a visible supply or drain connection. Note whether the leak occurs constantly or only when the sink is used. Photos of the wet area can also help explain what you observed.

When to contact a plumber

Call for leak repair when water keeps returning, the affected area is spreading, you cannot identify or control the source, or the leak is interfering with normal sink use. Prompt service is also appropriate when the cabinet or nearby materials are getting wet.

Choose the Leak Repair service

A leak under a sink belongs with plumbing and is more specific than a general home-service request. Use the Leak Repair service page to review the mapped provider options, then confirm that the company serves your address and handles the type of under-sink leak you observed.

Questions to ask before work begins

Ask what information or photos would help them assess the leak, what work they expect to perform, and whether the quoted scope includes locating the source and testing the area afterward. In Texas, ask which plumbing license or registration applies to the person performing the work. The Texas State Board of Plumbing Examiners licenses plumbers and issues plumbing licenses, endorsements, and registrations.

Your next step

If the leak is active or returning, open the Leak Repair service page and confirm provider availability for your Austin address. Have your observations and photos ready, and describe when the water appears and where it first collects.
