Unionville is one of Markham's best-known communities: the historic Main Street village by Toogood Pond, and around it subdivisions from the 1970s and 1980s and larger executive homes. Many of those houses are now on their second or third owner and their second round of plumbing.

In the heritage homes near Main Street, plumbing has usually been updated in stages, so old and new pipe sit side by side and the work has to respect what is behind the plaster. In the subdivisions, it is the age-related list: water heaters, sump pumps, shut-off valves, fixtures, and main drains under mature trees.

Tell us roughly when the house was built and what is going on, and your request goes to one plumber who covers Unionville and the rest of Markham.

York Simcoe Plumbing is a free referral service: your request goes to one independent local plumber serving Unionville, and they quote and do the work.

Unionville Questions, Answered

Yes. Inside the house it is ordinary plumbing, done carefully. Main Street Unionville is in a heritage conservation district, so anything that changes the outside — a new vent through a wall, for instance — should be checked with the City of Markham first.

Older multi-turn valves often seize after years without use, and forcing them can break them. If a fixture valve will not close, use the main shut-off. Replacing old valves with quarter-turn ball valves is a common job, and worth doing before you need them.

Yes. Unionville is a community in the City of Markham, so permits and municipal programs go through the City of Markham.
