Contractors in Markham: Hire Local, Vetted Trades

Markham stretches from heritage Unionville — where older homes call for careful, sympathetic work — to the newer subdivisions of Cornell and north Markham. Townhomes and semis make up a big share of the stock alongside detached houses.

The recurring Markham projects on BuildBridge: kitchen and bathroom renovations, basement finishing in the newer builds, and HVAC replacements as the first generation of furnaces and air conditioners in the 2000s subdivisions ages out.

How BuildBridge Works in Markham

BuildBridge is one marketplace for all of Toronto and the GTA — there is no separate Markham site and no Markham office. You post your job once, with photos, your budget range and your postal code. Verified trades who serve Markham see it and quote on the same scope, so you compare real numbers for the same work. Your phone number and email stay hidden until a trade has quoted and you choose to talk to them.
