What Is Basement Renovation?
Basement renovation is the process of updating, modernizing, or completely reconfiguring an already-finished below-grade space. Unlike finishing, which starts from bare concrete, renovation involves demolition of existing finishes followed by a rebuild with improved materials, layout, and building systems. In the Greater Toronto Area, basement renovation costs typically range from $40 to $85 per square foot and takes 5 to 10 weeks to complete. Projects require building permits and must meet current Ontario Building Code standards.

Our Basement Renovation Process in Don Mills
For Don Mills residents, our structured basement renovation process minimizes disruption while maximizing value.
Assessment & Renovation Planning
We evaluate your existing basement's condition, identifying what needs to be replaced, what can be preserved, and where improvements will have the greatest impact. We document structural elements, moisture concerns, and any code deficiencies in the original build.
Design & Material Selection
Our team creates a renovation plan that addresses your goals — whether that means opening up a cramped layout, adding rooms, upgrading finishes, or all of the above. We help you select materials that balance aesthetics, durability, and budget.
Permit Acquisition & Demolition
We secure the necessary building permits from your municipality. Controlled demolition removes outdated finishes, revealing the underlying structure for inspection. Any mould, water damage, or structural issues are addressed before rebuilding begins.
Structural Updates & System Upgrades
With the space opened up, we upgrade insulation, replace outdated electrical wiring and panels, reroute plumbing as needed, and make any structural modifications such as removing or relocating walls and adding headers for wider openings.
Rebuild & Finishing
New framing, drywall, flooring, and trim transform the space. Updated lighting plans with pot lights, modern fixtures, and accent lighting bring the design to life. All finishes are applied according to your selected materials and colour scheme.
Inspection, Cleanup & Handover
The renovated space passes municipal inspection to confirm code compliance. We perform a thorough cleaning and conduct a walkthrough with you to review every detail, ensuring the finished product meets your vision before the project is officially complete.
Why Don Mills Homeowners Choose Us
Modernize Outdated Space
Renovation replaces dated finishes from the 1980s and 1990s with contemporary materials and design. An updated basement looks, feels, and functions like a brand-new space, dramatically improving your daily living experience.
Fix Hidden Problems
Renovation uncovers and addresses issues that may be hidden behind existing walls — mould, water infiltration, inadequate insulation, outdated wiring, or structural concerns that could worsen over time if left unattended.
Reconfigure the Layout
Unlike surface-level updates, a full renovation allows you to completely reimagine the floor plan. Remove walls to create an open concept, add rooms that did not exist before, or relocate utilities for a more efficient design.
Boost Resale Appeal
In the competitive Greater Toronto Area real estate market, a recently renovated basement with modern finishes significantly increases buyer interest and supports a higher asking price compared to homes with original or dated lower levels.

Basement Renovation FAQ for Don Mills Homeowners
How much does a basement renovation cost in Toronto?
Basement renovation in Toronto and the GTA typically ranges from $40 to $85 per square foot, higher than basic finishing because it includes demolition and disposal of existing materials. For a 1,000 square foot basement, expect $40,000 to $60,000 for a standard renovation and $65,000 to $85,000 or more for a high-end overhaul with premium materials. Costs increase if structural modifications, plumbing additions, or electrical panel upgrades are required. Our free in-home estimates provide exact pricing based on your specific conditions.
What is the difference between basement renovation and finishing?
Basement finishing converts a raw, unfinished space into a livable area, starting from bare concrete walls and floor. Basement renovation, on the other hand, involves updating or completely redoing an already-finished basement. Renovation includes demolition of existing finishes, addressing any underlying issues, and rebuilding with modern materials and design. Renovation typically costs more per square foot because of the added demolition, disposal, and potential system upgrades involved.
How long does a basement renovation take?
A typical basement renovation in the GTA takes 5 to 10 weeks from construction start. The timeline depends on the scope — a cosmetic refresh with new flooring, paint, and lighting may take 3 to 4 weeks, while a gut renovation with layout changes, plumbing, and electrical rework takes 8 to 10 weeks. Add 2 to 4 weeks for permit processing before construction begins. We provide a detailed project timeline during the planning phase so you know what to expect at every stage.
Should I renovate my basement or sell my home?
In the current GTA real estate market, renovating your basement is almost always more cost-effective than selling and purchasing a larger home. Real estate transaction costs — including land transfer tax, legal fees, moving costs, and commission — often total $80,000 to $120,000 or more on a typical GTA home sale. A comprehensive basement renovation at $50,000 to $80,000 delivers hundreds of square feet of updated living space while avoiding those transaction costs entirely.
Can you renovate a basement that has had water damage?
Yes, and in fact renovation is often the best response to water damage. Our process includes full demolition of affected materials, professional mould remediation if needed, identification and repair of the water source, and installation of waterproofing measures before rebuilding. We use moisture-resistant materials like closed-cell spray foam insulation, mould-resistant drywall, and waterproof flooring to prevent future issues. Addressing the root cause during renovation ensures the problem does not recur.
