A wet cabinet floor is one of the most common reasons Fairfield homeowners call for sink repair. Supply lines and drains hide behind the cabinet door, so a slow drip can soak the shelf for weeks before anyone notices, warping shelving and starting mold.
We find the exact source before quoting. Common culprits include loose or corroded supply line connections, a cracked or misaligned drain flange, failed plumber’s putty or silicone around strainers, worn slip-joint washers, and condensation from cold water lines in warm weather. Fairfield’s hot summers make condensation easy to mistake for a leak, and ruling that out is part of our diagnosis.
The fix is usually straightforward: new supply lines and shutoff valves, reseating or replacing the strainer, rebuilding the drain assembly, or replacing a corroded trap. We protect the cabinet and show you what was leaking.
The P-trap is the curved pipe under every sink. It holds water that blocks sewer gas, and it catches debris before the main drain line. When P-trap replacement is needed, you will usually notice a persistent foul smell, visible corrosion on metal traps, dripping slip joints, or chronic slow draining.
We replace traps and the full drain assembly when needed, including the tailpiece, wall tube, basket strainer, and pop-up drain assembly, matched to your setup: chrome or brass for exposed runs, PVC or ABS for hidden cabinet plumbing. Correct alignment, fresh washers and gaskets, and a full test confirm it holds water and drains freely.
One local note: mineral deposits build up fast on metal drain parts in Solano County water. A scale-coated pop-up stopper can look like a drainage problem when it just needs cleaning and adjustment, and we will try that first.

Reseating a strainer or swapping a P-trap is a smaller job than replacing a whole sink and rebuilding the drain.
Standard strainers and traps are basic parts; specialty assemblies or hard-to-find flange sizes for older sinks change the scope.
A standard drop-in kitchen sink is straightforward; an undermount, farmhouse, or vessel sink adds mounting and sealing work.
A wide-open vanity is easy. Tight pedestal clearances or plumbing behind finished panels takes longer.
If the disposal must come out to access the drain, that adds steps and testing.
Re-caulking the rim, resealing a countertop seam, or a water-stained cabinet floor are often part of the job.
Fixing three bathroom sinks in one visit costs less per sink than three separate visits.
Commercial fixtures and code-required installations carry different parts and compliance steps.
The kitchen sink is the hardest-working fixture in the house. The basket strainer area is the classic failure point: years of hot and cold water plus constant vibration work the seal loose until water seeps around the flange. Sprayer hoses crack where they flex, caulk lines at the rim fail, and older stainless steel develops stress cracks around drain holes.
We repair or replace strainers, reseal rims, replace sprayer hoses, rebuild drain assemblies, and re-secure undermount sinks that have dropped. For rim rust: surface rust can be treated and resealed, but rust through the flange means replacement is coming.
Kitchen sinks and disposals share a drain, so they share problems. The number-one issue is leaks at the disposal flange: vibration loosens the mounting ring, the seal degrades, and water runs into the cabinet. We also see leaks from a failing disposal body and clogged discharge pipes.
If the unit still has life, our garbage disposal repair service can reseat it and replace the flange and seals. If you are adding or upgrading a disposal, see garbage disposal installation. We handle the flange, drain plumbing, dishwasher connection, and a full test.
Bathroom sinks fail differently. The big enemy is slow drainage from hair, soap, and toothpaste residue coating the pop-up assembly, with mineral scale speeding the buildup. We clear the blockage, clean or replace the stopper, and adjust the linkage.
Porcelain chips and cracks are the other common call. A hairline crack around the drain can leak into the vanity cabinet with every use, hidden behind a closed door. We assess whether it is cosmetic (sealable) or structural (spreading). We also repair loose pedestal sinks, vanity sinks with leaking supply lines, and vessel sinks with failed drain gaskets.
Garage, laundry room, and mudroom utility sinks take rougher use: paint cleanup, pet washing, garden soil, mop water. The failures are familiar: cracked basins, leaking supply connections, and drains clogged with sediment or paint solids. We repair and replace utility sinks, upgrade undersized traps, and add shutoff valves where the original setup skipped them.
Sometimes sink installation is the right answer: structural cracks, deep rust-through, a drain hole too corroded to hold a new strainer, or repeated failures that cost more than a fresh start. Remodels are the other big reason: a new countertop is the perfect time to upgrade the sink.
We install drop-in, undermount, farmhouse (apron-front), vessel, and bar/prep sinks in stainless steel, cast iron, fireclay, composite granite, and porcelain. Every sink installation includes proper drain rough-in (verified before you buy), new supply lines and shutoff valves, a new strainer or pop-up assembly, and correct sealing. For countertop projects, we coordinate with your installer on the template cut.
One caution: moving a sink to a new location means moving drain and water lines inside the wall or floor, a bigger job than a straight swap, priced in full in your written estimate.

Repair covers fixable failures: a leaking strainer, a corroded trap, a cracked supply line, or a failed seal. Replacement is for structural damage, like a crack through the basin or rust eaten through a steel flange. We inspect it and price both options honestly.
Usually loose or corroded supply line connections, a failing basket strainer seal, worn slip-joint washers, or cracked P-traps. Disposal mounting flanges are a frequent source under kitchen sinks. We diagnose the exact source before quoting.
Yes, in most cases. The trap connects with slip joints and can be replaced on its own when the tailpiece and wall tube are sound. We inspect the full assembly first, since a corroded trap often means neighboring parts are not far behind.
Odors usually come from food trapped in the basket strainer or around the disposal flange, a dry or cracked P-trap, or biofilm in the drain. We clean and inspect the strainer, trap, and disposal connection, and replace what has failed.
Yes. We can add or upgrade a disposal in the same visit, including the flange, drain connection, and dishwasher tie-in. See our garbage disposal installation.
