What shapes the price of a renovation in Oshawa
Every house is different, so every project is quoted in writing after a visit. These are the factors that move the number.
Scope & size
How many rooms, how much square footage, and whether it is a refresh or a full gut.
Layout changes
Moving walls, plumbing or gas lines costs more than keeping the existing layout.
Structure
Load-bearing walls, beams, foundations and additions need engineering and permits.
Materials & finishes
Cabinets, counters, tile, flooring and fixtures range widely in price.
Condition of the house
Old wiring, plumbing, water damage or uneven floors found along the way.
Permits & drawings

Home Renovations in Oshawa: Kitchens, Bathrooms, Basements and More
Century and heritage homes in Oshawa
Oshawa's older homes, many built before the Second World War, have character worth keeping and systems that usually are not: knob-and-tube or early wiring, plaster and lath walls, stone or block foundations, and framing that is rarely square. We open these houses carefully, test for asbestos and lead paint before demolition, and plan for what is behind the walls instead of pretending it will not be there.
Post-war bungalows and back-splits in Oshawa
The post-war bungalows and back-splits in Oshawa are solid, simple houses that renovate well. Typical work includes taking out the wall between the kitchen and living room, replacing galvanized supply pipes and cast-iron drains, upgrading the electrical service, and making better use of the basement, which often already has a side door at grade.
Newer homes built since 2000 in Oshawa
Newer Oshawa homes have good bones and builder-grade finishes. The most common projects are finishing the basement, often with a bathroom roughed in by the builder, and upgrading kitchens and ensuites. Engineered floor joists cannot be cut or notched without an engineer's approval, and in the first years of ownership it is worth checking how a change affects your Tarion new-home warranty.
Kitchen Renovations in Oshawa
In Oshawa, homeowners from Downtown Oshawa and Lakeview call us when the kitchen no longer fits the way they live. Some want an island and an open sightline to the family room, others want the same footprint with better cabinets, lighting and counters. Both are worth doing well.
We handle the whole Oshawa kitchen remodel as one project: demolition, any wall removal or structural work, plumbing and electrical by licensed trades, cabinets, counters, backsplash, flooring and paint, in the right order and on a written schedule.
Bathroom Renovations in Oshawa
Whether it is a main bath in Downtown Oshawa or a new basement bathroom anywhere in Oshawa, we plan the layout, the plumbing and the waterproofing first, then the finishes you will see every day.
Every Oshawa bathroom we build gets a continuous waterproofing membrane, a properly sloped shower base and an exhaust fan sized for the room, with plumbing by licensed trades and tile set flat and true.
Basement Finishing in Oshawa
Oshawa basements vary a lot, from older foundations that need careful moisture work to newer poured basements ready to finish. We plan each one around the house it is in.
Every Oshawa basement we finish starts with a moisture check, then proper foundation insulation, framing, electrical and plumbing, drywall, below-grade flooring and lighting, with egress windows wherever a bedroom is planned.
Legal Basement Apartments in Oshawa
Demand for legal basement apartments in Oshawa is strong, whether for rental income, a parent moving closer or a young adult who wants their own space. Many post-war bungalows, older downtown homes and newer north-end subdivisions in Downtown Oshawa, Lakeview and Eastdale have basements well suited to a secondary suite.
Secondary suites in Oshawa are approved by the City of Oshawa, which sets its own zoning, parking and entrance rules on top of the Ontario Building Code and Fire Code. We check what your lot allows, coordinate drawings and the permit, then build the suite and book inspections through to final sign-off.
Home Additions in Oshawa
In Oshawa, an addition is often the answer for families who love their street in Downtown Oshawa and Lakeview but have outgrown the house. With post-war bungalows, older downtown homes and newer north-end subdivisions, rear additions, second storeys and main-floor suites are all common.
Accessible Renovations in Oshawa
Many Oshawa homeowners want to stay in the neighbourhood they know, in Downtown Oshawa, Lakeview and Eastdale and beyond, and the right changes to the bathroom, entrances and main floor make that safer and easier.
Renovating in Durham Region
Durham mixes post-war bungalows and older brick homes near the lake with large newer subdivisions to the north, so the work here ranges from first renovations on decades-old houses to finishing builder-grade basements in homes only a few years old.
