Basement Apartment

Build a legal basement apartment in Ontario โ€” fire separation, egress, permits and registration handled, so the rent you collect is rent you can keep.

Basement Waterproofing

Wet basement in spring? Get the cause fixed, not just the symptom โ€” crack sealing, weeping tile, sump pumps and real waterproofing, quoted free.

Basement Underpinning

Underpinning digs your basement floor down to full ceiling height โ€” engineered, permitted structural work common in Toronto's century semis.

Basement Bathroom

Add a basement bathroom the right way โ€” rough-ins put to use, concrete opened only where needed, ejector pumps where gravity won't co-operate.

Basement Electrical & Pot Lights

Basement pot lights, new circuits and panel questions โ€” handled by a Licensed Electrical Contractor under an ESA notification, as Ontario law requires.

Basement Flooring

Basement flooring for Toronto and GTA homes โ€” vinyl plank, carpet and engineered options over concrete, with moisture and levelling handled first.

Basement home theatre builds in the GTA โ€” soundproofing, acoustics, projector or panel, dedicated circuits and wiring run while the walls are open.

Common questions

What kind of basement jobs can I request?
Anything below grade: full finishing and renovations, legal basement apartments and in-law suites, waterproofing and crack repair, underpinning, bathrooms and kitchens, flooring, ceilings, pot lights, home theatres and gyms โ€” right down to sealing a single crack or swapping a sump pump. If you don't see your job listed, describe it in the quote form and we'll tell you if we can help.
Is the quote really free?
It is. You describe the work, add photos if you have them, and get a quote with no obligation. You decide whether to go ahead.
My basement gets damp. Can I still finish it?
Yes โ€” after the dampness is understood and fixed. Sometimes that's a downspout extension, sometimes a crack injection, sometimes real waterproofing. Finishing over a moisture problem just hides it until it ruins the new work, so we always deal with water first. It's the least glamorous part of the job and the most important.
Who does regulated work like electrical or plumbing?
Ontario regulates certain trades for good reason. Electrical work is performed by Licensed Electrical Contractors under ESA notifications, plumbing by licensed plumbers, and gas work by TSSA-certified technicians. Structural work like underpinning is engineered and municipally permitted. Jobs that need a licensed trade are routed to contractors who hold that licence.
Which areas do you cover?
Toronto and the GTA are the core โ€” Mississauga, Brampton, Vaughan, Markham, Oakville, Pickering and everywhere between โ€” plus the wider Golden Horseshoe: Hamilton, Niagara, Kitchener-Waterloo, Guelph and Barrie. If you're near the edge of that map, send the request anyway and we'll confirm.
