Basement Waterproofing in Alliston & New Tecumseth, Ontario
We are based in Barrie, minutes from Alliston & New Tecumseth — the same crew, the same written scope and quote, and the same 24/7 emergency line: (705) 300-0086.
What makes Alliston & New Tecumseth basements leak
Heavy clay is common here. Clay holds water against the wall long after the rain stops, which is exactly the condition that pushes water through a shrinkage crack.
On clay lots, exterior work plus proper backfill often outlasts anything done from inside — but we still check the cheap causes first.
We cover Alliston, Beeton and Tottenham — and the assessment is the same everywhere: we trace where the water enters, inside and out, then quote the right-sized fix in writing.
