Weeping Tile Cost in Ottawa: Why There Is No Tile-Only Range
Priced inside exterior or interior waterproofing
We found no tile-only range with two independent published sources.
The published Ontario price pages we found fold weeping tile into the per-foot ranges for exterior and interior work. Use one of those estimators for your walls, and ask each quote to say whether the tile is replaced and where it drains.
Last reviewed 2026-10-01. Published figures, not quotes; yours will differ.
Use the wall estimators
- Exterior waterproofing: $100 to $350 per linear foot
- Interior drain and sump: $70 to $150 per linear foot
| Item | Minimum | Clause |
|---|---|---|
| Drain tile or pipe | at least 100 mm in diameter | 9.14.3.2 |
| Top of the tile | below the bottom of the floor slab | 9.14.3.3 |
| Open butt joints | 6 mm to 10 mm | 9.14.3.3 |
| Stone over top and sides | at least 150 mm of crushed stone or clean coarse granular material | 9.14.3.3 |
| Where it drains | a sewer, a drainage ditch, a dry well, or a sump with a pump | 9.14.5 |
What the quote should say
- Whether the tile is replaced or left in place
- Pipe size and the stone cover
- Where it drains, and whether it ties into the sanitary sewer now
- Who pulls the permit
- Who requests the locate
