A leak under the sink can damage cabinets, flooring, and drywall quickly, even when it looks minor. In North Vancouver homes, we often see slow leaks that only show up after using the tap, running a dishwasher, or draining a full sink. We identify the cause and confirm the best fix before any repair begins.
Every visit includes a $99 call-out fee for a visual first check.

If water is actively flowing and you cannot stop it at the shutoff, see Emergency Plumbing. For broader leak issues, visit Leak repairs.
Some leaks are obvious. Others only show up after using the sink. These are the most common signs we see under kitchen and bathroom sinks.
Damp shelves, swollen particle board, or staining often indicates a slow drip from a trap, supply line, or valve.
If the cabinet gets wet after the sink drains, the trap, slip joints, or tailpiece connection may be leaking.
Old angle stops can seep around the stem or packing nut, especially after being turned.
Even small leaks can keep the cabinet damp and create odours before you see standing water.
Water may run along the cabinet floor and drip down at corners or toe kicks, making the source look misleading.
Supply line leaks often show up only under pressure, such as when the tap or dishwasher is running.
Under-sink leaks usually come from a small number of failure points. Confirming the right one matters because the repair differs.
Loose slip joints, aged washers, cracked trap components, or poor alignment can cause drips after draining.
Failed putty or sealing surfaces at the strainer can drip down the tailpiece and appear like a trap leak.
Worn braided hoses, compression fittings, or connections at the faucet can leak under pressure.
Valve stems and packing nuts can seep, especially if the valve has not been operated in years.
Kitchen sink cabinets often include dishwasher feed and drain connections that can loosen or crack over time.
If the cabinet stays wet but connections are dry, the leak may be behind the wall. That is where leak detection can help.
We focus on confirming the exact leak point, protecting your cabinet, and completing a clean repair with clear approval before work begins.
We inspect the cabinet, trap, strainer, supply lines, shutoff valves, and surrounding cabinetry for the most likely source.
We run the fixture and observe under load so the true leak point is identified, not guessed.
If the repair is visible, we provide a fixed price. If the source is hidden, Investigation Time may be required, and we confirm this before proceeding.
We repair or replace the failed component, then test under normal use conditions to confirm there are no further leaks.
If we see aging valves or corrosion that may fail next, we explain options so you can decide what to address now versus later.
