PricingEvery basement is priced from the same quote sheet, line by line: a 1,000 sq ft basement with a three-piece bathroom comes to about $67,800 before HST, and the price per square foot falls as the basement grows because the permit, bin, breakers, stairs and bathroom cost the same at any size. During your in-home consultation we review every detail (finishes, plumbing, electrical, bathrooms, kitchens, millwork and structural work), and you have the itemized quote within 24 to 48 hours.

PricingQuotes vary because companies include different scopes: permits, design, plumbing fixtures, warranty, labour quality, and mainly finishes and materials. A low price frequently means those items come back later as "extras." Put every quote side by side at the same scope so you're comparing apples to apples.

PricingYes. In a market like Toronto, usable square footage is one of the most valuable features you can add, and a legal basement apartment earns on top of that through rental income. We will not put a return percentage on it, because nobody can promise one. The quality of the final product determines the true value of the investment.

TimelineOnce permits are approved, about two months for a typical basement, about two and a half with custom cabinetry, about three for a legal suite, with a written completion date on every contract backed by our $200 a day on-time guarantee.Basement renovation timelineEvery stage of the build, week by week→

Taping and sanding. Tiling. Flooring, trim and doors. Painting. Fixtures, finishes, final inspection and your walkthrough. A typical basement runs about two months end to end, and you watch every step live in DesirePro, our client app.

TimelineYes. Basement renovations run year-round in the GTA, including through winter. The work happens indoors below grade, so snow and cold rarely affect the schedule. Winter is often a quieter season for contractors, which can mean faster scheduling for you.

PermitsYes. You need a building permit whenever a basement is finished for personal use or as a secondary unit. Both require the minimum building inspections: structural, framing, insulation, plumbing and HVAC. A secondary unit has additional requirements based on your scope. Permit drawings are prepared and stamped by a licensed structural engineer, and we handle the filing and every inspection.

Build qualityThe finish quality we're known for is only possible because of our trades, and most of our trades have worked with Kam for years. Ask our clients: on days when several specialists show up together, it feels more like a family gathering than a construction site. That consistency is what keeps quality and timelines reliable.

Build qualityLuxury vinyl plank (LVP). It's waterproof, warm underfoot and durable, and it handles a below-grade space's moisture and temperature swings far better than hardwood or solid laminate. The golden rule: minimum 7mm thickness and above. Why we use it on almost every project: the full LVP breakdown.

WarrantyWe offer a lifetime workmanship warranty covering the quality of the work and installation, in writing, in the contract. Buyers value a finished basement that comes with documented, guaranteed work.Our lifetime workmanship warrantyWhat it covers, in plain terms→
