Mc Mann, Drive in Thorold
Leaky basement from ground water and a broken sanitary sewer pipe.
Welland St South in Thorold
We just purchased a Victorian home (built 1884). The previous owner allowed one of the basement support beams to be cut for duct work. As a result, there is floor weakness in the floor above. We would be interested in seeing if extra support posts may help fix our situation. Thank you
