Under-Sink Leak Repair
The drip traced to its actual source and fixed there — trap, tailpiece, supply, seal, or faucet base.
Services
The cabinet under a sink tells the truth about it. Warped shelf paper, a musty smell, a ring of swollen particleboard — every one means water is escaping somewhere in that tangle of trap, tailpiece, and supply lines. All of it is fixable, and finding the actual source is the part that takes the experience.
The approach
Under-sink leaks like to lie about where they're from. Water runs along pipes and drips from the lowest point, so the puddle is rarely under the actual failure — a leaking faucet base can read as a bad trap, a failed sink-rim seal as a supply problem. I trace it dry-paper style to the true source before touching anything, because replacing the wrong part stops exactly nothing and the cabinet keeps drinking.
Drain assemblies are honest work that reward being done right. Slip joints want clean mating surfaces, fresh washers, and sensible tightness — cranked-down and cross-threaded is how 'fixed' drains weep for months. Metal traps that have scaled and pitted get replaced rather than coaxed. And where a disposal is in the mix, its connections get remade as part of the job, since disposal joints are the most common leakers under a kitchen sink.
Sink replacement is mostly about the interface with the counter. Drop-ins are straightforward swaps when sizes cooperate. Undermounts live or die by their mounting and seal — a failing undermount in a stone counter is a real repair, and I do those. Bath vanity sinks often come as a top-and-bowl unit, which turns a sink swap into a light vanity update. Whatever the format, the job ends with clean caulk lines, tight connections, and a dry paper towel under everything the next morning.
