Plumber in Markham: what local homes need

Markham has heritage houses in Unionville and Markham Village, 1970s and 80s homes through Thornhill and Milliken, and newer communities like Cornell, Berczy Village and Cathedraltown. Each era has its own plumbing: cast iron and galvanized in the heritage areas, copper and polybutylene in the middle decades, and PEX or Kitec in the newer builds.

Finished basements and second kitchens are common in Markham, which puts more demand on drains and water heaters than the house was first built for. Slow floor drains and hot water that runs out early are two of the most frequent calls we take here.

Emergency plumber in Markham

Emergency calls in Markham are often about basements. Many homes have finished lower levels with a second kitchen or bathroom, so a backed-up floor drain or a failed sump pump affects living space, not just storage. In the heritage homes of Unionville and Markham Village, old galvanized and cast iron pipe can fail without much warning. If water is coming up through a floor drain, stop using water in the house until we get there.

If water is flowing where it should not, shut off the main valve first. Our guide on how to shut off your main water valve shows where to find it, and what to do when a pipe bursts covers the next steps. Then call us. Dispatch answers 24/7 and sends an emergency plumber to your Markham address, day or night.

Markham plumbing questions, straight answers.

A floor drain is the lowest opening on your main drain, so it is the first place a blockage shows. Grease, wipes or tree roots further down the line are the usual causes. We clear the line and can run a camera to check for damage.

One call covers it: repair, emergency, install or reno.

The dispatch line is answered around the clock. Tell us what is going on and a licensed plumber is on the way with an honest arrival window.
