Whole-Home Renovations in Markham
With heritage homes and large newer family homes, Markham has plenty of homes ready for a full update, and buyers in Unionville, Markham Village and Cornell often renovate before or soon after they move in.
We manage whole-home renovations in Markham from scope to final inspection: drawings and permits coordinated with the City of Markham, demolition, structural work, licensed trades, insulation, drywall, kitchens, bathrooms, flooring and finishing, on a phased written schedule.
Call (647) 424-1511 or send the form on this page for a free home renovation quote in Markham. Tell us what you want to change, add a few photos of the space, and we will book a visit and send a written quote that lists the scope, the materials, the permits involved and the schedule.
Markham homes
What whole-home renovations involves in Markham's houses
Century and heritage homes in Markham
A whole-home renovation is often the best way to deal with an older Markham house, because wiring, plumbing, insulation and structure can all be brought up to date while the walls are open. We plan around what is worth keeping, such as trim, stairs, doors and original floors, and replace what is not.
1970s to 1990s family homes in Markham
Many Markham homes from the 1970s to the 1990s change hands and get renovated top to bottom: kitchen, bathrooms, flooring, smooth ceilings, lighting, windows and the basement. Doing it as one project means the electrical, plumbing and finishes are consistent from room to room.
Newer homes built since 2000 in Markham
For newer Markham homes, a whole-home renovation is usually about finishes and function rather than systems: upgraded kitchen and bathrooms, flooring, lighting, built-ins and a finished basement, done in one coordinated project.
Rules in Markham
Permits and approvals for whole-home renovations in Markham
Building permits
Building permits in Markham are issued by the City of Markham. Electrical work anywhere in Ontario is done by a licensed electrical contractor under an Electrical Safety Authority (ESA) permit. We confirm what your project needs before you sign and book every inspection.
Conservation authority
Much of Markham falls within the Toronto and Region Conservation Authority (TRCA) watershed. Building near a shoreline, river, floodplain, valley or wetland can need a conservation authority permit before the municipality will issue a building permit. We check the regulation mapping for your property early so it does not hold up the schedule.
Heritage properties
Markham includes the Unionville and Markham Village heritage conservation districts. Exterior changes to a property in a heritage district, or to a house designated under the Ontario Heritage Act, generally need heritage approval as well as a building permit. We check your property's status before design starts.
Testing before demolition
Homes built before the 1990s can contain asbestos in plaster, textured ceilings, floor tile, vermiculite insulation and pipe wrap, and homes from before the 1960s often have lead paint. In Markham's older houses we test suspect materials before demolition and handle them by the regulations if they are found.
The service
Whole-Home Renovations, Managed as One Project
When a house needs more than one room updated, doing it as one project saves time, money and disruption. Plumbing, electrical and structural changes can be planned together, inspections happen once, and the finishes are consistent from room to room.
Whole-home renovations range from updating every room in a dated house to full gut renovations that take a home down to the studs to redo insulation, wiring, plumbing and layout. Many clients buy an older home in a neighbourhood they love and renovate it before moving in.

What kinds of Markham homes do you work on?+
All of them. Housing in Markham includes century and heritage homes, 1970s to 1990s family homes and newer homes built since 2000, and each comes with its own considerations, from older wiring and foundations to builder warranties, septic systems and shoreline rules. We plan the work around the house you actually have.
Do I need a conservation authority permit in Markham?+
Only if your property is in a regulated area, such as near a shoreline, river, valley, floodplain or wetland. Much of Markham falls within the Toronto and Region Conservation Authority (TRCA) watershed. We check the mapping for your address before applying for the building permit.
Can I live in my home during a whole-home renovation?+
Sometimes, if the work can be phased so a kitchen or bathroom stays usable. For gut renovations, most clients stay elsewhere. We discuss the options when we plan the schedule.
Do I need an architect or designer?+
For layout changes, additions or structural work you will need drawings for the permit. We can coordinate drawings with a designer or engineer, or work from plans you already have.
How is a whole-home renovation priced?+
It is quoted from a detailed scope: room by room and trade by trade. We break the quote into phases so you can see where the budget goes and decide on options.
Do you offer whole-home renovations across Markham?+
Yes. We work throughout Markham, including Unionville, Markham Village, Cornell, Berczy Village, Wismer, Cathedraltown, Milliken and Box Grove, and in nearby Richmond Hill, Scarborough, Vaughan, Stouffville and Aurora.
