Smiths Falls has a unique combination of geography, soil, and housing stock that makes basement waterproofing more critical here than in many Ontario cities.
Smiths Falls sits at the heart of the Rideau Canal system — and that proximity to managed waterways means the local water table is directly influenced by canal water levels. Homes near the lower downtown core, along Chambers St, or near the locks can see groundwater intrusion long before a rainstorm even starts.
Why basements get wet in springLanark County’s soil is predominantly heavy clay — the same type of soil that causes foundation problems across Eastern Ontario. Clay expands when wet and shrinks when dry, creating lateral pressure on foundation walls and floor-wall joints with every seasonal cycle. Over time, this movement opens cracks and pathways for water.
Foundation waterproofing explainedA significant portion of Smiths Falls’ housing was built between 1890 and 1960 — brick homes with stone or early concrete block foundations. These foundations were built without modern waterproofing membranes and are now 60–130 years old. Deteriorated parging, failed mortar joints, and outdated drainage make them prime candidates for water intrusion.
Interior vs exterior waterproofingFrom crack injection to full exterior excavation, we offer every solution Smiths Falls and Lanark County homes need — backed by a lifetime transferable warranty.
Interior drainage channels and a sump pump system intercept water at the footing level before it reaches your floor. The most cost-effective long-term solution for Lanark County homes with clay soil pressure.

Get a quotePolyurethane or epoxy injection seals active cracks in poured concrete walls permanently. Fast, minimally invasive, and ideal for the hairline cracks that form in Smiths Falls homes due to freeze-thaw cycling.
Get a quoteEssential for homes near the Rideau River and Canal. We install primary sump pumps with battery backup systems — critical when spring storms knock out power at the exact moment water levels peak.
Get a quoteOriginal clay tile drainage systems in Smiths Falls’ older homes often collapse after 50–80 years. We replace failed systems with modern perforated pipe wrapped in filter fabric — solving problems at the source.
Get a quoteImproperly installed or clogged window wells are a common leak entry point in Smiths Falls’ brick homes. We install properly graded wells with drainage that redirect water away from your basement walls.
Get a quoteHomes within a few blocks of the Rideau Canal or Rideau River face elevated groundwater risk year-round, not just in spring. The canal lock system actively manages water levels, and that directly affects the water table in the surrounding neighbourhood. A properly sized sump pump with battery backup is non-negotiable in this area. Power outages and peak flooding often happen simultaneously — a battery backup sump pump keeps working when you need it most. Read our sump pump buying guide →
Answers to the questions Smiths Falls homeowners ask us most.
Pricing depends on the solution required:
Older block or stone foundations common in Smiths Falls may be at the higher end due to the additional prep required. We provide free, no-obligation quotes for every project. See our full Ontario pricing guide →
Subsidy programs are updated periodically, so check directly with the Town of Smiths Falls and Lanark County for current offerings. Additionally, Ontario’s provincial Basement Flooding Protection Subsidy Program may apply to qualifying repairs including sump pump installation, backwater valve installation, and disconnection of downspouts. We can help you identify what qualifies during your free inspection.
For Smiths Falls homes on Lanark County clay soil with lateral wall pressure, a combination often works best. Interior drainage is the most cost-effective way to manage active water intrusion and is minimally disruptive. Exterior waterproofing is recommended when the foundation wall itself is crumbling, bowed, or the original mortar has completely failed — common in Smiths Falls homes from the 1890s–1940s.

Absolutely yes — and we strongly recommend a battery backup sump pump. The Rideau Canal lock system actively manages water levels, and that proximity means groundwater can rise independent of whether it’s raining at your location. Spring thaw flooding along the Rideau River is well-documented, and those same events typically coincide with power outages. A battery backup sump pump continues operating for 8–12 hours without hydro. Read the full sump pump buying guide →
