We were worried about what it would take to fix a basement in a house this old. Hydronyx dug out the exterior and sealed it properly, and three winters later we haven't had a drop of water. Best money we've spent on the house. Thomas T.Leslieville, Toronto
We could barely stand upright in our basement. Hydronyx underpinned it, and we went from 5'8" to a full 8-foot ceiling. We finally have space we actually want to use. singh S.North York
Hydronyx wasn't the cheapest quote, but it was the most transparent. They walked us through everything upfront, and there were no surprise costs. john L.Scarborough
