Richmond Hill and GTA basement contractor
Basement renovations and finishing in Richmond Hill and the GTA.
Plan a basement for everyday use, with a clear scope for the existing conditions, layout, flooring, walls, lighting and related trades.
Start with the basement questions
Permits, waterproofing, and egress come before finishes.
A basement renovation starts with how you intend to use the space and whether the existing conditions support that use. We start by identifying permit questions, water entry or moisture risks, ceiling height, insulation, services, and whether egress windows are required for legal bedrooms.
Requirements vary by municipality and intended use. A legal bedroom or rental apartment may involve additional fire separation, exits, plumbing, electrical, HVAC, zoning, and permit review. Owners should confirm current requirements for the exact property before demolition or construction.

Basement use cases we can plan around.
Control moisture and comfort
Insulation and moisture control protect the finished result.
Before framing, review foundation walls, slab edges, plumbing, drains, ventilation, condensation, previous water entry, and any visible staining or odour. A finished surface should not hide an unresolved moisture source.
Insulation, vapour control, air movement, heating, and dehumidification decisions depend on the existing construction and local requirements. JT can organize the renovation scope around those questions while owners obtain the municipal, design, engineering, environmental, or specialist advice the actual condition requires.
Plan from real conditions
Finish the basement with a documented scope.
Photos, measurements, intended use, access details, moisture history, permit questions, and finish priorities give the walkthrough a stronger starting point.
JT’s rental and interior renovation experience also helps connect basement decisions to kitchens, bathrooms, flooring, paint, trim, and handover requirements when the project includes more than one room or a rental use.
