Toronto's Most Professional Waterproofing Company

Nonleak Waterproofing is your local waterproofing and foundation contractor. We service Toronto and surrounding GTA. Our company can design and build your project and exceed your expectations. A happy customer in our mind will be a repeat customer or a great referral.
Why choose us?
Many of the large and medium waterproofing companies in the GTA do not actually have enough qualified workers to finish their projects. Most of these companies goal is to use their name to secure multiple projects at the same time, while subcontractors do all the work from start to finish. We are one of these qualified subcontractors that the large and medium companies use all the time. We see the extra charges being built into the project costs to cover other company expenses, sales commission, meals, travel, advertising budget, and other unrelated overhead costs.
