BASEMENT UNDERPINNING VANCOUVER

Unlock the Space Beneath Your Home

FOUNDATION UNDERPINNING, BASEMENT CONVERSIONS & WATERPROOFING IN VANCOUVER.

Many Vancouver homes built in the early 20th century have low-ceiling basements designed for storage — not living. Kerr Design Build converts these underused spaces into full-height, liveable suites, family rooms, and home offices. We also repair failing foundations and waterproof basement walls — all managed in-house from design to construction.

SEE HOW WE WORK →

Basement underpinning — digging out and lowering the existing floor to create full ceiling height

Foundation wall extension — extending walls downward to new footings for structural support

Legal basement suites — fully designed and permitted liveable spaces

Foundation repair — underpinning cracked, crumbling, or sinking foundations

Perimeter drainage — lowered and rerouted internally, no exterior excavation required

Waterproofing — water-resistant sheathing and drainage protection throughout

THE UNDERPINNING PROCESS

Minimal Disruption. Maximum Gain

The best part about basement underpinning — you don’t have to leave your home. All work is performed from below while you continue living in the upper floors. The exterior of your home is untouched. Perimeter drainage is rerouted from the inside, so no flower beds or landscaping are disturbed. When the work is complete, you have an entirely new floor of prime living space — without moving, without adding on, and without touching the exterior of your home.

Experience You Can Build On

Basement underpinning is not work to hand to just anyone. A poorly executed underpinning job can cause your home to shift. Incorrect drainage can lead to leaks and water damage in a newly renovated space. Over 35 years, Kerr Design Build has created more than 30 new basement living spaces for homeowners across Vancouver — with the experience and accountability to get it right.

Yes — foundation and structural work requires a Building Permit. We manage the full City of Vancouver permit process in-house as part of our service.
