Home Renovations in Thornhill, on Both Sides of Yonge
Our office is in Thornhill, so the kitchens, bathrooms and basements we renovate here are close to home, and we work out whether your permit goes to Vaughan or Markham before any work starts.
West of Yonge: Working With the City of Vaughan
On the Vaughan side, permit applications, drawings and inspection bookings go to the City of Vaughan's building department. For a basement with a new bathroom, a removed load-bearing wall or a new window opening, we prepare the documents the application asks for and book each inspection so the job is not left waiting with open walls.
East of Yonge: Working With the City of Markham
On the Markham side, the same kinds of work go through the City of Markham instead. The questions are similar (structure, plumbing, fire separation, egress from a basement), but the forms, the submission process and the inspection booking are Markham's own. We handle that paperwork, so you are not learning a second municipal system halfway through a renovation.

The Rooms Thornhill Homeowners Want Rebuilt
Most renovations start with the rooms a family uses every day: a kitchen that no longer fits how people cook, a bathroom whose tub and tile are worn out, or an unfinished basement that could become living space. Often two or three of these are combined, and we plan them as one schedule rather than separate jobs.
We also take on finish work that changes a room without moving walls: feature walls, fireplace surrounds, flooring, trim and lighting. The wall in this photo is that kind of job, with a large slab surface, a recessed insert and light along the edges.

A Look at Finished and In-Progress Rooms


Why a Contractor Down the Road Makes the Job Easier
A renovation involves more short trips than most people expect: the first measure, a second look once walls are open, meeting an inspector, receiving a delivery, checking a detail with you before tile goes up. With the office in Thornhill, each of those is a short drive rather than a trip across the GTA, so small questions get answered on site the same day instead of waiting for the next planned visit.
It matters most when something unexpected turns up behind a wall, such as old wiring, a damaged joist or a leak under a shower. We come back, look at it with you and agree on the fix in writing before work carries on, so the rest of the schedule does not stall.

Thornhill Renovation Questions
How do I know if my Thornhill home is in Vaughan or Markham?
Yonge Street is the dividing line: west of it is the City of Vaughan, east of it is the City of Markham. If you are unsure, look at who sends your property tax bill. That city issues your building permit and carries out the inspections. We confirm it during the free visit, before any drawings are prepared.
Does the side of Yonge matter for an interior renovation?
For the work itself, no. A kitchen or bathroom is built the same way on either side. What changes is the paperwork: which building department reviews the application, how drawings are submitted and who comes to inspect. When a permit is needed, we prepare the application for the correct city and handle the inspection bookings.
My house is near the old village core on Yonge. Are there extra rules?
Possibly. Both Vaughan and Markham have heritage conservation district rules for parts of historic Thornhill, and exterior changes there, such as windows, additions or cladding, can need heritage approval on top of a building permit. Interior renovations are usually not affected. We check your address with the city before planning any exterior change.
Can you renovate a condo unit in Thornhill?
Yes. Condo work follows the corporation's rules as well as the city's: permitted working hours, elevator booking, protection of hallways and lobbies, and sometimes written approval from management before work begins. Send us those rules at the start, and we plan demolition, deliveries and the noisiest work around them.
