Basement Renovation FAQs

How much does a basement renovation cost?
Our basement renovations start from $50,000. The final cost depends on the scope — a basic finished basement costs
less than a full legal suite with separate entrance, kitchen, and bathroom. We provide a detailed quote during your free
consultation.
How long does a basement renovation take?
Most basement renovations take 10–16 weeks. Legal suites with plumbing and separate entrances are on the longer end. Your project manager provides a detailed timeline before work begins.
Do I need a permit to finish my basement?
Yes. Ontario building code requires permits for basement renovations involving framing, plumbing, electrical, or structural changes. Legal suites have additional requirements including fire separation, egress windows, and separate metering. We handle all permits and inspections.
Can you build a legal basement suite?
Yes — legal basement suites are one of our specialties. We handle the full process: separate entrance, kitchen, bathroom,
bedroom, fire separation, egress windows, and all inspections required by your municipality.
What areas do you serve?
We’re based in Burlington, Ontario and serve Burlington, Oakville, Milton, Guelph, and surrounding areas in the GTA.
