Basement Renovation FAQs

Answers to common questions about basement and home renovations in the GTA.

Yes. Most significant renovations, including basements, require a building permit in Ontario. This is especially true if you are adding plumbing for a new bathroom, altering the structure (such as load bearing wall removal), or creating a legal rental suite. Our team manages the entire permit process to ensure full Ontario Building Code compliance.
Specifically for basements, the cost in Richmond Hill typically ranges from $70 to $120 per square foot. A basic finishing of a 600 sq.ft space might start around $42,000. For a comprehensive legal rental suite involving separate entrances and full kitchens, costs generally range between $85,000 and $120,000 depending on finishes.
A standard basement finishing project typically takes 6 to 12 weeks from the start of demolition to the final finishing touches. The overall timeline can vary based on the complexity of the design, custom material lead times, and the duration of the municipal permit approval process.
Once your renovation is complete, protecting it is vital. Our Annual Home Care Program includes comprehensive seasonal inspections, proactive repairs, HVAC system checks, thermal imaging inspections, and regular servicing of critical systems to protect your investment and prevent unexpected water damage or breakdowns.
