Simple Process

How Basement Finishing Works in Oakville

  1. 1

    Pre-Underpinning Design

    We design the finished layout before the underpinning starts. Bathroom rough-ins, kitchenette location, and beam pockets are placed for the new ceiling height.

  2. 2

    Rough-Ins

    Once the new slab has cured, framing, electrical, plumbing, and HVAC rough-ins go in. Inspections happen at this stage so issues are caught before drywall.

  3. 3

    Drywall & Finishing

    Insulation, drywall, mudding, and primer. Trim, flooring, kitchenette and bathroom fit-out follow in sequence.

  4. 4

    Final Inspection

    Final electrical and building inspections. Secondary suite registration with the City of Toronto. Walkthrough handover with the homeowner.
