Basement Waterproofing in Dundas
Dundas sits at the bottom of the Niagara Escarpment, and water runs off the slopes on three sides onto the valley floor, where many homes stand on century stone and brick foundations. Quotes are free and written, and the labour is warranted for life.

If your Dundas basement gets wet, the town's shape is a big part of the reason. Dundas is the Valley Town: the escarpment wraps it on three sides, so snowmelt and rain run down the slopes and collect on the valley floor, and Spencer Creek carries that water through town toward Cootes Paradise.
Ground that catches that much runoff stays wet longer, and much of the housing in it is old: century brick and cut stone behind a 19th-century downtown.
How we waterproof is on our basement waterproofing page. This page is about why Dundas in particular stays wet. Send the form for a free written quote.
Water first: the valley sends it toward your wall
Runoff from the escarpment reaches the valley floor and soaks the ground around older foundations, and the soil here holds water rather than shedding it.
Century stone and brick foundations
Many Dundas homes, in the downtown core around King and Sydenham and on the streets that climb toward the escarpment, stand on old stone or brick foundations. Some of that stone was quarried from the escarpment itself.

Straight answers
Why does my Dundas basement take on water?
Because the town sits in a bowl. The escarpment wraps Dundas on three sides, melt and rain run down the slopes onto the valley floor, and the ground stays wet.
How much does basement waterproofing cost in Dundas?
It depends on the job. The size of the job, access on the lot, the soil and how bad the water problem is all change the price. We do not publish a flat rate because it would mislead. We visit, measure and give you a free written quote, and the number on the quote is the number on the invoice unless you change the job.
What does the lifetime warranty on labour cover?
Our workmanship: the site preparation and the work done as part of the job, and repairs needed because that work was done wrong. It lasts as long as you own the home where we did the work, and it is stated on every written quote. Materials carry their manufacturers' warranties.
