Common Basement FAQ's
How much does it cost to finish a basement in Thornhill?
Most Thornhill-area basement renovations run between $55 and $120 per square foot, depending on whether you are building a full second suite, a finished family room, or something in between. Plumbing, egress windows, and electrical upgrades are the biggest cost drivers. We give you a line-by-line quote so you can see exactly where the dollars are going.
Do I need a permit to finish my basement?
If you are adding bedrooms, a bathroom, a second suite, or doing any structural, electrical, or plumbing work, yes, a permit is required. We handle drawings, the submission, and all required inspections so it stays compliant and so the work is on record when you eventually sell.
Can you build a legal second suite in my basement?
Yes. We design legal basement suites to meet local by-laws for egress windows, fire separation, sound, insulation, ceiling height, and ventilation. We also handle the permit drawings and inspections, so you end up with a suite that is safe, rentable, and properly on record with the City.
How long does a basement renovation take?
A finished basement usually takes six to twelve weeks on site, depending on size, plumbing scope, and whether it includes a kitchen or bathroom. Permit timelines can add a few weeks on the front end. We share a written schedule once the design is locked, and we keep you updated weekly.
What about moisture and waterproofing?
We take it seriously. Before framing goes up, we look at grading, foundation cracks, and any signs of past water issues, and we recommend interior or exterior waterproofing when it is needed. There is no point in finishing a basement that is going to have water problems two winters later.
Does renoWOW offer a warranty on basement renovations?
Yes. Every renoWOW basement renovation is backed by a two-year workmanship warranty.
Is renoWOW licensed and insured?
Yes. renoWOW is licensed in Toronto, WSIB-covered, and carries $5 million in liability insurance.
