Water in the basement is stressful enough without mystery pricing. Here's what crack injection, weeping tile systems, exterior excavation and sump pumps realistically cost in Guelph and Wellington County in 2026 — and what moves the number.

A single poured-concrete crack is a few hundred dollars; a stone-foundation century home in downtown Guelph needing full exterior work is a five-figure project. The ranges below reflect typical 2026 pricing for professional, warrantied work in the Guelph area.
| Service | Typical 2026 Price (Guelph Area) | Notes |
|---|---|---|
| Foundation crack injection | $400–$1,000 / crack | Poured concrete foundations only |
| Interior weeping tile system | $100–$250 / linear ft | Slab break, drainage pipe, membrane, re-pour |
| Exterior excavation waterproofing | $150–$350 / linear ft | Dig to footing, membrane, new weeping tile |
| Sump pit & pump installation | $1,500–$3,500 | Battery backup adds to the total, worth it |
| Full perimeter project | $10,000–$30,000+ | Whole-foundation systems with sump & discharge |
To put it in real terms: a single leaking crack in a poured foundation is usually a same-day, under-$1,000 repair. One wet wall handled from the inside typically runs $3,000–$10,000. Chronic water on multiple walls, or a block or stone foundation, pushes into full-perimeter territory.
Poured, block or stone — each needs a different approach
Deeper footings mean more excavation or slab work
Decks, additions and tight lot lines complicate digging
Finished basements add removal and restoration cost
Here's why two Guelph houses on the same street can get very different waterproofing quotes:
Interior weeping tile systems are usually the more economical fix per foot and can be installed year-round, regardless of landscaping. Exterior excavation waterproofing costs more but stops water outside the wall — the right call when the foundation itself needs protection or grading is being redone anyway. Many Guelph projects combine approaches: exterior work on the accessible walls, interior drainage where excavation isn't practical. A free on-site assessment tells you which mix makes sense for your home — and gives you a firm, itemized price.

Our services: Foundation Crack Injection, Sump Pump Installation, Exterior Waterproofing — see the 2026 Cost Guide for pricing.
Polyurethane or epoxy crack injection typically costs $400 to $1,000 per crack in 2026, depending on crack length, wall thickness and access. It's the most economical fix for a single leaking poured-concrete crack.
Interior drainage systems generally run $100 to $250 per linear foot installed — slab break, perforated pipe and gravel, wall-base membrane, and re-concreting. A typical 30–40 ft wall run lands between $3,000 and $10,000.
Excavating to the footing, applying membrane and installing new weeping tile typically costs $150 to $350 per linear foot, depending on depth, access and obstructions like decks, porches or utilities.
A new sump pit and pump typically costs $1,500 to $3,500, depending on pit location, discharge routing and whether you add a battery backup — highly recommended given spring storms and power outages.
Full-perimeter projects — interior or exterior systems around the whole foundation with sump and discharge — commonly run $10,000 to $30,000+, driven by foundation length, depth, access and finishing repairs.
Foundation type (poured vs block or stone), depth and soil, equipment access, landscaping and finishes that must be removed and restored, and how the water will be discharged away from the home.
