Basement Renovation FAQ — Toronto and GTA
How long does a basement renovation take in Toronto?▼
A full basement renovation is typically completed within 3–4 weeks, depending on the scope, layout changes, and whether a bathroom is being added. Our team follows a structured schedule to ensure consistent progress and a smooth, efficient timeline.
What is included in a full basement renovation in Toronto?▼
A complete renovation can include framing, drywall, insulation, flooring, lighting, electrical upgrades, heated floors, a bathroom build, feature walls, painting, and custom storage. We offer full design-to-completion services tailored to how you want the space to function.
How much does a basement renovation cost in Toronto and GTA?▼
Most basement renovations range from $25,000 to $40,000, depending on finishes, flooring choice, bathroom addition, and any structural or electrical upgrades. We provide clear, detailed proposals so you know exactly what's included before work begins.
Do I need a permit for a basement renovation in Toronto?▼
Yes — basement finishing requires a City of Toronto building permit, along with electrical and plumbing permits when those trades are involved. Ceiling height (typically 6'5" minimum finished), egress windows, and fire separation rules all apply. We handle all permits as part of the renovation, including drawings, application, and inspections.
Can a basement renovation include a bathroom or second suite in Toronto?▼
Yes — adding a basement bathroom is a common scope addition, and Toronto allows second suites in many residential zones. A second suite requires meeting egress, fire separation, and parking requirements set by the City. We confirm what is allowed for your property before quoting.
What flooring is best for a basement renovation in Toronto?▼
For most Toronto basements, waterproof vinyl plank is the safest choice — it handles the moisture and temperature swings typical of below-grade rooms in Ontario. Engineered hardwood can be installed in basements with proven dry slabs and a vapour barrier, but it carries more risk. Tile is appropriate for bathrooms and laundry areas.
