Custom Basement MakeOver

As experienced basement contractors, we manage every detail — from structural framing, moisture protection, and R-20 insulation to egress window installation, plumbing and electrical rough-ins, professional drywall, and premium finishing. We know Ontario Building Code requirements inside and out, and we handle all permit applications and municipal inspections on your behalf.

Basement Finishing vs. Basement Renovation — What's the Difference?

Understanding the distinction is important for planning and budgeting. Basement finishing refers to converting a raw, unfinished concrete space into livable square footage — including framing, insulation, electrical, plumbing, drywall, flooring, and finishing. Basement renovation refers to upgrading or reconfiguring an already finished basement — such as updating an outdated layout, replacing flooring, or adding new features. RK Custom Renovations handles both, and we will help you determine the right approach during your free consultation.

How Much Does It Cost to Finish a Basement in the GTA?

Basement finishing costs in the Greater Toronto Area typically range from $55 to $120 per square foot, depending on the scope of work, finishes selected, and whether plumbing is involved.

Frequently Asked Questions — Basement Renovations

Do I need a permit to finish a basement in Ontario?

In most cases, yes. Any basement renovation that involves changes to the building's structure, plumbing, electrical, or HVAC systems requires a building permit in Ontario. Creating a legal basement apartment requires additional permits including an ESA electrical permit and plumbing permit. Finishing a basement without a permit can result in fines, forced removal of work, and complications when selling your home. RK Custom Renovations handles all permit applications for Burlington, Oakville, and Milton.

What are the Ontario Building Code requirements for a basement bedroom?

The Ontario Building Code requires that every basement bedroom has an egress window for emergency escape. The window opening must be at least 3.8 square feet with a minimum height and width of 15 inches. The bedroom must also have smoke detectors, proper ceiling height (minimum 6'5" in most areas), and if it is a legal apartment, fire separation between the basement unit and the main floor.

Is finishing a basement worth it for resale value?

Absolutely. Industry data shows that a professionally finished basement in Ontario typically returns 70% to 75% of your investment at resale. A legal basement apartment can return even more through ongoing rental income. In the competitive Burlington and Oakville real estate markets, a finished basement is a major selling point that differentiates your home from comparable properties.

What is the best flooring for a basement in Canada?

The best basement flooring options for Canadian homes include luxury vinyl plank (LVP), engineered hardwood, porcelain tile, and carpet tile. LVP is the most popular choice because it is waterproof, durable, warm underfoot, and available in a wide range of styles. Engineered hardwood offers a premium look with better moisture resistance than solid hardwood. We help you choose the best option during your consultation based on your budget and lifestyle.

How long does it take to finish a basement in Burlington?

A typical basement finishing project in Burlington takes 6 to 12 weeks depending on scope and complexity. A basic finish with framing, insulation, drywall, and flooring may take 6 to 8 weeks. A full legal basement apartment with kitchen, bathroom, separate entrance, and all code requirements can take 10 to 14 weeks. We provide a detailed project timeline during your consultation.
