Residential Plumbing
Residential Plumbing, done properly
Newmarket has a mix of older homes near the historic downtown and Main Street, and newer family neighbourhoods such as Stonehaven, Woodland Hill and Summerhill. Cold winters on the northern edge of York Region make frozen pipe prevention, reliable boilers and snow-melting systems especially valuable here.
We work throughout Newmarket, including Stonehaven, Glenway, Summerhill, Woodland Hill, Armitage, Bristol-London, Downtown Newmarket. Every visit starts with a clear diagnosis and a written price before work begins, and emergency calls are answered 24/7 at (416) 700-3040.
Beyond everyday plumbing, our team designs and installs boilers and mechanical rooms, radiant in-floor heating and heated driveways for Newmarket homeowners and builders, and handles commercial plumbing for local businesses.
