Whole-Home Renovations in Oshawa
Oshawa has older homes around downtown and the original auto-plant neighbourhoods, post-war bungalows across the south and east, and newer subdivisions in Windfields, Taunton and Northglen near Durham College and Ontario Tech University. That variety makes Oshawa a great place to buy a house with good bones and renovate it to suit your family.
We manage whole-home renovations in Oshawa from scope to final inspection: drawings and permits coordinated with the City of Oshawa, demolition, structural work, licensed trades, insulation, drywall, kitchens, bathrooms, flooring and finishing, on a phased written schedule.

Oshawa homes
What whole-home renovations involves in Oshawa's houses
Century and heritage homes in Oshawa
A whole-home renovation is often the best way to deal with an older Oshawa 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.
Post-war bungalows and back-splits in Oshawa
Post-war Oshawa bungalows are among the best candidates for a full renovation: simple structure, good-sized lots and layouts that open up easily. A typical project opens the main floor, rebuilds the kitchen and bathroom, upgrades the electrical service and plumbing, adds insulation and finishes the basement.
Newer homes built since 2000 in Oshawa
For newer Oshawa 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 Oshawa
Permits and approvals for whole-home renovations in Oshawa
Building permits
Building permits in Oshawa are issued by the City of Oshawa. 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 Oshawa falls within the Central Lake Ontario Conservation Authority (CLOCA) 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
If your Oshawa home is designated under the Ontario Heritage Act or sits in a heritage conservation district, exterior changes 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 Oshawa'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 Oshawa homes do you work on?+
All of them. Housing in Oshawa includes century and heritage homes, post-war bungalows and back-splits 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 Oshawa?+
Only if your property is in a regulated area, such as near a shoreline, river, valley, floodplain or wetland. Much of Oshawa falls within the Central Lake Ontario Conservation Authority (CLOCA) 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.

Yes. We work throughout Oshawa, including Downtown Oshawa, Lakeview, Eastdale, McLaughlin, Northglen, Taunton and Windfields, and in nearby Courtice, Ajax, Bowmanville, Pickering and Newcastle.
