Basement Renovation · Newmarket, York Region
Basement renovation in Newmarket, from finishing bare concrete to remodelling an old rec room or building a basement apartment to the approved permit drawings. Licensed and WSIB insured, with 15+ years of renovating behind us.
What’s included
A basement renovation in Newmarket with us is one of three jobs: finishing bare concrete from the slab up, remodelling a finished basement after taking out what is there, or building a second unit with its own kitchen and bathroom, fire separation, exits and egress windows.
Posts, stairs and mechanical equipment are already there, so the rooms are planned around them.
The finishes that make a basement feel like the floors above it.
A bathroom, a kitchen or a wet bar below grade, with the plumbing to serve it.
Your municipality and the Building Code set the requirements a separate unit is built to.

Strip lighting runs above the shelves, and a desk is built into the same wall beside them.

Open oak shelves stand either side of the hood, and black-framed windows wrap the corner of the room.

A navy double vanity beside a generous shower in warm stone tile.
A clear glass panel keeps the shower open to the room, and a niche for bottles is set into its tiled wall.

Cedar, glass
A glass-fronted cedar sauna beside a calm wellness space.
Cedar boards line the walls and the ceiling inside and carry on across the wall outside the glass, so the sauna reads as part of the room.

Oak, pale stone, navy
A kitchen, dining space and living room connected by warm oak flooring.
Tall windows and a glazed door run the length of the back wall, so the island, the table and the sofa share the same daylight.

Good to know
Finishing a basement is named on the Town of Newmarket's permit list, so drawings and a review are part of every basement we finish here. If heating is carried into the new rooms, the Town can ask for heat loss and heat gain calculations, to confirm the furnace can carry the extra space, and a duct layout by a qualified designer. The Town needs roughly 10 to 15 working days to review a complete application, a wait that sits before the first stud goes up. After the review, the inspections listed on the reviewed plans set the pace, and the walls stay open until the rough-in has passed.
Town of Newmarket: building and renovating ↗Dry comes first in every basement we renovate. Before any framing we check the walls and floor for moisture, and a leak, a crack or damp is repaired while the concrete is still bare. In a Newmarket house from the Traditional Suburban years, built between the 1940s and the 1990s, the foundation has had decades of seasons, so that check carries weight in the budget.
An unfinished basement is the simplest starting point. A half-finished one is sorted into what stays and what goes, and a fully finished one that no longer suits is taken back before it is rebuilt. A bathroom, a wet bar or a second kitchen brings plumbing rough-in and ventilation into any of them. Whichever you have, the design follows how you want to use the floor, and the permit drawings are made from it.
A basement apartment is a separate home within the house, built to approved permit drawings. Newmarket adds two steps beyond the build. By-law 2013-13 requires a home with an additional residential unit to be registered with the Town, and each unit needs one more parking space on the lot. Both are checked before the unit is designed, so neither holds up a finished apartment.
