What basement waterproofing costs in Muskoka
Homeowners search cost first. Here is the range we actually see in Muskoka, and why granite and access change the number.
Typical ranges
Interior waterproofing in Muskoka often lands between $90 and $200 per linear foot, including a drain, membrane along that wall and a tie-in to a sump. Exterior excavation with membrane and new weeping tile is commonly $140 to $300 per foot, because Canadian Shield bedrock and tight cottage access slow the dig.
Crack injection is usually priced per crack, not per foot. A simple interior injection can start in the mid hundreds. A sump replacement without a new pit is often in the high hundreds; a new pit, pump and discharge can reach the low thousands.
What moves the number
How close granite sits to the footing, how many walls are wet, whether the cottage is finished, how tight the side yard is, and whether the existing pump and discharge can stay. A waterfront lot with a deck and pines is a different job than a clear year-round Bracebridge bungalow.
Why we will not quote from a text message
Two lower levels can look identical in a photo and need opposite systems. We inspect, then we write a scope. If you want a ballpark before we visit, the ranges above are honest for cottage country in 2026.
