What Waterproofing actually costs in St. Catharines
Straightforward waterproofing on a typical St. Catharines home runs $395 to $632. Complex jobs — multi-storey access, heritage masonry, or downtown parking — push the top end toward $1,027. 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.
Why St. Catharines pricing differs from neighbouring cities
St. Catharines's 82% natural gas mix drives which waterproofing scopes come up most. 18% of the housing stock predates 1960, which is why waterproofing jobs here average slightly more site prep than newer suburbs.
