Renovation contractors in Markham, Ontario
Markham needs a building permit for finished basements, second units and any plumbing inside a building (a separate plumbing permit). A rear-yard deck needs none if it is under 10 m², not attached to the house and no more than 600 mm (2 ft) above the ground; anything else does. Fences need no permit unless they enclose a pool. If the basement is part of it: Markham’s Private Plumbing Protection Rebate pays up to $1,750 for an indoor backwater valve, $2,000 for an outdoor one, and up to $5,000 to disconnect the weeping tile and add a sump pump — in flood-prone areas, with approval from Environmental Services before the work. It runs to April 2027. Doyo books renovation across Markham: describe the job, see the full price before you book, and pay only when it is done.
