- A basin that drains slowly, backs up, or holds standing water
- A drip at the trap, the tailpiece, or one of the drain connections
- A faucet, basket strainer, or basin gone loose and wobbly
- A musty smell or visibly swollen, discolored cabinet wood

Why Professional Help Matters
Under-sink leaks are easy to misread, because water runs along the pipe and drips down far from where it actually started. A skilled plumbing technician checks the trap, the drain flange, the tailpiece, and the supply lines to find the true origin, then resets the drain on fresh putty and reseals the connections so the fix holds. Snugging an old slip joint or a corroded chrome-over-brass drain assembly tight without cracking it takes a practiced hand, and knowing when to replace a fitting rather than force it is exactly where a proper repair earns its keep.

In Sacramento kitchens, hard-water scale narrows the drain line and drags out a slow-draining basin, while under older cabinets the original chrome-over-brass drain assemblies corrode and start to weep at the joints. Because a lot of the region's established homes still have long-lived original cabinetry and metal drain fittings, catching an under-sink leak early is exactly what saves a homeowner from tearing out a swollen cabinet base and a stained floor later on. Angle stops that have not been turned in decades are another common local find, and we replace the ones that seize or weep rather than leave them.

Frequently Asked Questions
It could be the trap, the tailpiece, the drain flange, one of the supply hoses, or an angle stop. Water tends to travel along the pipe before it drips down, so we trace it to the true source instead of resealing the first wet spot we see.
Grease, food, hair, and soap building up in the trap or branch line, hard-water scale narrowing an older pipe, or a partially failed drain assembly are the usual causes here. Clearing or replacing the culprit brings the flow back.
That pattern usually points to the drain flange or the trap connection rather than the supply lines, because the leak appears when a full basin releases a surge of water. We fill and release the sink to reproduce it, then reseal the assembly that is passing water.
Yes. Even a slow drip swells a particleboard cabinet base, feeds mold in the enclosed space, and can reach the subfloor over time. Catching it early keeps a quick fix from becoming a cabinet and flooring replacement.
Gurgling often means the branch line is partly blocked or not venting well, and an odor can come from buildup in the trap or a trap that has dried out. We clear the line and check the vent so both the sound and the smell go away.
Yes. We handle whatever the sink actually needs, whether that is sealing a leak, clearing a clog, or replacing a corroded drain assembly, so you are not left with half the problem and a second call.
