Forest Hill projects don't just lower a basement, they unlock premium living square footage. Most homes pair underpinning with luxury finishing: home theatres, full gyms, climate-controlled wine cellars, and guest suites. Toronto Basement Underpinning delivers basement underpinning, interior waterproofing, basement finishing, sump pump installation, concrete foundation repair, legal apartment conversions, walkout basements, and permit coordination - full scope, one licensed crew.
Neighbourhoods Served
The homeowners who contact Toronto Basement Underpinning are usually wrestling with one of these. We solve them properly - not with a quick fix that fails in two years.
Forest Hill 1920s-30s heritage homes typically have 6'4"-6'10" basements. The space is unusable as a finished living level, and the heritage value of the upstairs makes a tear-down impossible.
Stone-and-rubble foundations under Forest Hill estate homes have endured a century of root pressure from mature trees, frost cycles, and grade water. Active settlement is common on Old Forest Hill Road.
Original perimeter drainage on most Forest Hill homes is past its service life. Expensive interior finishes upstairs are at risk every time spring melt overwhelms the failing system.
Forest Hill Heritage Conservation District covers most addresses, including Spadina Road and Forest Hill Village. Heritage permit timelines run 8-12 weeks. We carry the coordination.
Complete framing, rough-ins, drywall, flooring and trim to convert a raw basement into a legal apartment or luxury living suite. Available in Forest Hill as part of our full-turnkey underpinning service.
Exterior stairwell and door opening cut into your foundation wall, engineered to code, permitted, and waterproofed. Creates a private entrance for a legal basement suite or direct backyard access. Available in Forest Hill as part of our full-turnkey underpinning service.
Crack injection, footing repair, and structural reinforcement for Toronto homes, with an honest call on when full underpinning is the right answer instead. Available in Forest Hill as part of our full-turnkey underpinning service.
End-to-end drawings plus permit coordination, architect, structural engineer, City of Toronto submission, and Committee of Adjustment if zoning relief is needed. Available in Forest Hill as part of our full-turnkey underpinning service.
Full interior waterproofing of foundation walls, weeping tile, sump pit, and dimpled membrane, to stop leaks at the source. Available in Forest Hill as part of our full-turnkey underpinning service.
Underground plumbing, main drain replacement, and rough-ins for new bathrooms, most efficient when combined with underpinning or basement finishing. Available in Forest Hill as part of our full-turnkey underpinning service.
Primary plus battery backup sump pump systems sized for Toronto's freeze-thaw water table, eligible for the City of Toronto Basement Flooding Subsidy. Available in Forest Hill as part of our full-turnkey underpinning service.
Forest Hill underpinning requires both City of Toronto building permits and Heritage Conservation District approval, with most addresses falling under the heritage overlay covering Spadina Road and Forest Hill Village. Heritage review adds 8-12 weeks; our coordinator carries the file and the Committee of Adjustment hearing if an exterior change is involved.

Forest Hill projects are typically integrated with whole-house renovations, so our underpinning crew co-ordinates with your interior designer, custom millwork shop, and finishing contractors from week one. Larger lots simplify access; we stage equipment in the rear and protect mature landscaping with plywood matting and tree-protection fencing as standard.
Most Forest Hill homes are 1920s-1940s detached on substantial lots, often with original lath-and-plaster interiors and custom millwork that must be preserved. Foundations are concrete or stone-and-mortar, 6'4"-7'0" original ceilings. Underpinning here usually targets 9 ft+ for theatre and wine-cellar height. Engineering and finishing budgets are higher; the trade-off is no surprises.
“Old Forest Hill Road home with a stone foundation and elaborate millwork upstairs. TBU treated the original mouldings like a museum piece. Underpinning was clean, the engineer's stamp arrived two weeks after pour, and the high-end finishing matched the rest of the house.”

“Forest Hill Village 1920s home, full underpinning plus a complete basement renovation. The drawings package was thorough, every sub-trade showed up on schedule, and the pricing was exactly what the original quote said.”

Forest Hill Village
“Spadina Road North home in the Heritage District. We expected the heritage permit to take six months. TBU's coordinator pulled it in nine weeks. Underpinning finished on time and they waterproofed every basement wall while the perimeter was open.”
