Basement Waterproofing in Hamilton

Interior basement waterproofing in Hamilton, Burlington and Niagara, often paired with a basement gut. We open the walls and floor, expose the problem and carry out the waterproofing your basement needs.

Fix the water before you finish the basement

Water stains, musty smells and damp drywall usually mean water is getting through the foundation. Finishing over the problem only hides it. We start by removing the finished walls and flooring to expose the foundation, then show you where the water is getting in.

From there, interior waterproofing work can include crack repair, a membrane on the inside of the foundation walls, and a drainage channel to a sump. Every basement is different, so the scope and price are confirmed on the walk-through.

Why demolition and waterproofing go together

Waterproofing a finished basement means tearing out the finishes anyway. Doing the demolition and the waterproofing with one crew avoids a second set of trades, a second mess and a gap in the schedule. Your basement goes from leaking to ready for framing in one job.

Basement waterproofing questions

Something else on your mind? Call Rory directly at (289) 659-1488.

Common signs are water stains, white residue on the walls, a musty smell, damp carpet or drywall, and water after heavy rain or snowmelt.

Exterior waterproofing seals the outside of the foundation; interior systems manage water that gets in. The right choice depends on your home, access and budget, and we talk it through on the walk-through.

Sometimes. If the leak is in one area, we can open just that section. A full gut is better when the damage is widespread.

No. We leave the basement clean and dry for your contractor to frame and finish.
