Foundation repair help across Ontario
Foundations move with soil moisture, frost, drainage and age: cracks, sticking doors, uneven floors and bowing basement walls are common warning signs. Ontario Foundation Pro focuses on assessment and repair planning in Toronto, Ottawa, Mississauga, Hamilton and throughout Ontario.
We start with foundation type, soils and how far movement has gone, then plan support and drainage so you know what happens next.
