Full basement finishing, secondary-suite conversions, basement bathrooms and framing-to-flooring renovations for Guelph homes. This is finishing and renovation work — if your basement needs waterproofing first, see our sister site, Guelph Basement Waterproofing.
Two very different jobs get called "basement renovation" in Guelph. One is finishing an unfinished basement into livable space — framing, electrical rough-in, drywall, flooring, maybe a bathroom. The other is converting it into a legal secondary suite for rental income, which brings permits, egress windows and separate entrances into the picture. We handle both, and we ask which one you're after before we quote anything, because the permit and budget conversation is completely different.
Framing, insulation, electrical rough-in, drywall and flooring — turning an unfinished basement into a livable rec room, home office or extra bedroom.
Legal basement apartment conversions — separate entrance, egress window and permit coordination for a rental unit or in-law suite. Guelph has specific requirements for this; we help you plan around them, not around us.
Adding a full or half bathroom to a basement, including the plumbing rough-in most basements don't already have.
Wall framing, insulation and drywall for a partial or full basement build-out.
Basement-appropriate flooring (vinyl plank, laminate, tile in wet areas), trim, doors and paint to finish the space.
Egress windows are required for any basement bedroom and most legal suites — we coordinate the cut, the well, and the permit paperwork.
Secondary suites are a real driver here. With U of G and a tight rental market, a lot of Guelph basement reno inquiries are actually about creating a legal rental suite, not just finishing a rec room. That changes the scope: egress windows, a separate entrance, and a permit from the city before drywall goes up.
Waterproofing comes first, not last. If a basement has ever taken on water, that gets fixed before any framing goes in — finishing over a wet basement just hides the problem until the drywall's ruined. We'll flag it during the quote if we see signs, and point you to a waterproofing quote first if needed.
Permits aren't optional on a legal suite. A basement apartment without a permit and the required fire separation isn't something a landlord wants to find out about after the fact. We plan the job around what the city actually requires, not around skipping it.
It depends heavily on scope — a simple finish is a different budget than a full secondary suite with a bathroom and separate entrance. Request a quote and describe what you're after; we'll give you a number based on the actual job.
For a straightforward finish (no new bedroom, no new plumbing), often minimal permitting is needed. Add a bedroom, bathroom or secondary suite and you'll need permits — we help coordinate that as part of the job.
No. Waterproofing deals with moisture and foundation issues; this is the framing-to-flooring renovation that happens once the space is dry. If you're not sure which you need, tell us and we'll point you the right way — including to our sister site if it's a waterproofing issue.
A straightforward finish typically runs a few weeks; a secondary suite with a permit, egress window and bathroom takes longer once permit timelines are factored in. We'll give you a realistic timeline with the quote.
Often yes, subject to the city's zoning and building code requirements for secondary suites — separate entrance, egress window, fire separation. We'll tell you upfront if something in your specific basement makes that harder.
