Why Ajax pricing differs from neighbouring cities
Ajax's 70% natural gas mix drives which waterproofing scopes come up most. 4% of the housing stock predates 1960, which is why waterproofing jobs here average slightly more site prep than newer suburbs.
What Waterproofing actually costs in Ajax
Straightforward waterproofing on a typical Ajax home runs $438 to $702. Complex jobs — multi-storey access, heritage masonry, or downtown parking — push the top end toward $1,140. The variance is almost always access, not the work itself.
Line items to look for on a quote
A clean waterproofing 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.
