A dripping faucet, a sink that drains slowly, a new undermount sink for new counters or a full kitchen renovation. We handle the plumbing at, under and behind the kitchen sink.
Kitchen plumbing is the water supply, drain and fixture work at the kitchen sink, and Hayes Plumbing provides it for homes across Oshawa and Durham Region. It covers kitchen sink installation and repair (undermount, drop-in and farmhouse sinks), kitchen faucet installation, repair and replacement, the shut-off valves and supply lines under the sink, the drain and trap, and the dishwasher and refrigerator water line connections. During a renovation it also includes the rough-in: new or moved supply and drain lines, put in before the cabinets and counters. Replacing a sink or faucet in the same spot usually needs no permit, while new plumbing does, and we explain which applies to your project. We supply faucets from Moen, Kohler, American Standard and Riobel or install the one you have chosen, with a written price before work starts.

What does kitchen sink & faucet plumbing cost in Durham Region?
According to our 2026 Oshawa plumbing cost guide, an appliance hookup for a dishwasher or refrigerator water line typically costs $150 to $300, and clearing a clogged kitchen drain typically runs $150 to $400 depending on the severity and location of the blockage. Sink and faucet installation, valve replacement and renovation rough-in depend on the fixtures and the access, so we price them after a free in-home estimate. Fixtures we supply are priced separately, and you get the full price in writing before we start.
Common questions about kitchen sink & faucet plumbing in Oshawa and Durham Region.
It depends on the faucet, whether the shut-off valves and supply lines need replacing and how easy the space under the sink is to work in. We do not publish a flat rate. The in-home estimate is free, the price is in writing before we start, and a faucet we supply is priced separately.
Usually not when the new sink or faucet goes in the same place. Oshawa, Pickering and Scugog all list like-for-like fixture or faucet replacement as work that does not need a permit. Moving the sink, adding an island sink or running new drain lines is new plumbing, which needs a permit from your local building department.
No. Undermount sinks are fastened beneath the counter and are made for solid-surface, stone and quartz tops. Laminate counters usually take a top-mount (drop-in) sink, whose rim rests on the counter. Switching to a farmhouse sink with an apron front means cutting into the cabinet and the countertop.
First check that the shut-off valves under the sink are fully open. If hot and cold are both weak, a blocked aerator at the end of the spout is a common cause, and on faucets with a side spray the diverter can restrict flow. If only the hot or only the cold is weak, the cartridge usually needs replacing.
We supply Moen, Kohler, American Standard and Riobel kitchen faucets, and we also install faucets you have bought yourself after confirming they suit your sink and supply connections.
Yes. We rough in the supply and drain lines when a sink, dishwasher or fridge moves, then set the sink, faucet and appliance connections once the counters are in. Hayes Plumbing was named a CommunityVotes Oshawa 2026 Silver Winner in the Kitchen Specialists category.
