Local Expertise
Underpinning for Oshawa Homes
Oshawa's large stock of older bungalows and semis — many with basement heights of 5.5 to 6 feet — makes this one of our most active markets for underpinning. These lower city and Mountain properties have significant potential as basement apartments or additional living space once the floor is lowered to 8 feet. With Oshawa's rising rents, a basement apartment is increasingly a financially compelling reason to underpin. We price Oshawa underpinning competitively.
