What Moss Treatment actually costs in Welland
Straightforward moss and algae treatment on a typical Welland home runs $356 to $570. Complex jobs — multi-storey access, heritage masonry, or downtown parking — push the top end toward $926. The variance is almost always access, not the work itself.
Line items to look for on a quote
A clean moss treatment 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.
