Basement Waterproofing Cost Estimator: Work Out a Toronto CAD Range Before You Call
This basement waterproofing cost estimator turns a perimeter measurement into a Canadian dollar range for interior weeping tile or exterior membrane and drainage on a Toronto home. It uses the same published per-linear-foot bands we quote from, so the number it gives you is the number you can hold our written diagnostic against.

How to Measure Your Basement Perimeter
Measure along the inside face of each foundation wall at floor level and add the lengths together. For a partial system, measure only the walls where water actually appears. A typical Toronto semi-detached runs 90 to 120 linear feet in total, and a detached bungalow is usually 120 to 160.
The estimator uses midpoint rates: $165 CAD per foot for interior weeping tile and $275 CAD per foot for exterior membrane and drainage, then applies a range of plus or minus twenty percent. Exterior pricing varies more than interior because excavation depth, access, and landscaping reinstatement all move the number, which is why the written diagnostic is the figure to rely on.
