 Trustindex verifies that the original source of the review is Google. We were having constant basement leaks whenever it rained, and water even started seeping through the walls. After getting a few quotes, we decided to go ahead with full exterior and interior basement waterproofing along with a backwater valve installation. Waterproofing4less team explained everything in detail, kept us informed each day, and handled the whole process very neatly. They dug around the foundation, sealed all cracks, and installed an interior system with sump pump connection. The backwater valve gave us peace of mind knowing our basement won’t flood again. Everything looks clean and professional now, and our basement has been completely dry since. Highly recommend for their honest advice and hard work! Most importantly all at an affordable price.

We had a wet basement issue since a long time in our basement in Mississauga and we called them for the resolution.
