What should one wall of exterior waterproofing cost in Kanata?

Published Ontario contractor pricing for exterior waterproofing runs about $100 to $350 per linear foot of wall, commonly $150 to $250 per linear foot. A single wall in Kanata could land anywhere in that range depending on several factors specific to the job.

The length of the wall and how deep the foundation sits change the price, and deeper foundations and tight access cost more. Whether the contractor replaces the drain tile at the bottom of the wall, and where that tile drains to, also affects the price. If the interior side of the wall is finished, removing and restoring that finish adds to the cost as well.

A complete quote for one wall of exterior waterproofing should spell out:

• the linear footage being quoted and the depth of the excavation
• whether dampproofing or waterproofing is included, and which membrane or system is being applied
• whether the existing drain tile is being replaced and where it will discharge
• who requests the locate before any digging starts (Ontario Dig Authority asks for that request at least 5 business days before excavation, under Ontario's Underground Infrastructure Notification System Act, 2012)
• who pulls any required building permit

Get at least two itemized quotes so you can compare scope, not just price. A quote that is vague about tile replacement or membrane type is harder to compare than one that lists each item separately.

Before you sign, ask each contractor to confirm in writing whether the quote covers dampproofing or full waterproofing, and why they are recommending one over the other for your wall.
