Is weeping tile priced separately from the membrane on an Ottawa quote?

The published Ontario price pages we found fold weeping tile into the exterior and interior per-foot ranges rather than pricing it on its own. Published Ontario contractor pricing for exterior work, which covers excavation, the membrane, drainage and new tile, runs about $100 to $350 per linear foot of wall, commonly $150 to $250. That range assumes tile replacement is part of the scope; if a quote omits it, the per-foot figure may look lower but the comparison is not equal.

The same is true for interior drain and sump systems: published 2025-26 prices run about $70 to $150 per linear foot, and the drain channel at the base of the wall is priced as part of that system, not separately. Too few published figures exist for weeping tile priced entirely on its own to give a reliable standalone range, so if a quote breaks it out as a separate item, ask what that figure includes and excludes.

What changes the price on either approach is wall length, foundation depth, how tight the access is around the house, whether tile is being replaced and where it drains, what is finished on the inside, and whether a new sump pit is needed or an existing one is used.

A few things worth asking before you accept any quote:

• Does the quote name dampproofing or waterproofing? Ontario's Building Code treats them differently: dampproofing is the minimum where outside grade is higher than inside grade (clause 9.13.2.1), while waterproofing is required where hydrostatic pressure occurs (clause 9.13.3.1). Ask the contractor which one the quote covers and why.
• Is tile replacement included, and if so, where does it drain? The Code requires foundation drains to discharge to a sewer, a drainage ditch or a dry well (clause 9.14.5.1).
• Is the membrane work and the tile replacement priced together, or is one excluded? If excluded, ask for the reason in writing.

When you put two written quotes side by side, line up the wall lengths each covers, confirm whether each one names dampproofing or waterproofing and which Code clause the contractor says applies, and check whether tile replacement is in or out of each scope and where the drain discharges, so you are comparing the same job rather than two different scopes at different prices.
