What Flashing Repair actually costs in Markham
Straightforward repair on a typical Markham home runs $387 to $619. Complex jobs — multi-storey access, heritage masonry, or downtown parking — push the top end toward $1,006. The variance is almost always access, not the work itself.
Line items to look for on a quote
A clean flashing repair quote itemises: labour hours, materials with brand names, dump/haul fees, permits (where required), and a written warranty term. Anything lumped as "misc" or "shop supplies" over 5% is worth questioning.
Why Markham pricing differs from neighbouring cities
Markham's 72% natural gas mix drives which flashing repair scopes come up most. 8% of the housing stock predates 1960, which is why flashing repair jobs here average slightly more site prep than newer suburbs.
