Good renovations start before the first wall comes down.
Ontario Renovation Company is a renovation and construction company serving homeowners from Hamilton and the Grand River to Durham, Peterborough and the Bay of Quinte. We renovate kitchens and bathrooms, finish basements, build legal secondary suites and additions, and manage every trade along the way.
What separates a renovation that goes smoothly from one that drags on is the planning: a clear written scope, permits sorted before demolition, materials ordered on time and trades scheduled in the right order. That is where we put our effort.

Investment
What shapes the price of a renovation in Southern Ontario
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
Projects that need drawings, permits and inspections take more time and planning.

Questions
Frequently asked
How much does a renovation cost?+
It depends on the size of the space, the scope, the materials and whether walls, plumbing or electrical are changing. Tell us about the project and send a few photos, and we will visit and send a free written quote.
Do you handle permits?+
Yes. We tell you which parts of your project need a building permit, coordinate drawings where needed, apply for the permit and book the inspections.
Who does the electrical and plumbing?+
In Ontario, electrical work must be done by a licensed electrical contractor under an Electrical Safety Authority permit, and plumbing must be done to code. Those trades are part of the project and scheduled by us, so you have one point of contact.
How long will my renovation take?+
Every project is different. A bathroom takes far less time than a basement apartment or an addition, and permits and material lead times affect the start date. Your written quote includes a realistic schedule.
Can I live at home during the renovation?+
For most kitchen, bathroom, basement and deck projects, yes. For gut renovations, many clients stay elsewhere. We plan the work to keep disruption as low as possible.

Home Renovations Across Southern Ontario
Kitchen and Bathroom Renovations
A kitchen renovation is the project most homeowners think about longest, and the one where planning matters most. Before anything is ordered, we look at how the room is used: who cooks, where people gather, what storage is missing and what is not working about the current layout. Then we design around that, whether the answer is new cabinets in the same footprint or a new layout with an island where a wall used to be.
A bathroom is the hardest-working room in the house for its size. Water, steam and daily use find every weak point, so a good bathroom renovation is mostly about what goes behind the tile: a properly sloped shower base, a continuous waterproofing membrane, correctly sized ventilation and plumbing that is done right the first time.
Basements and Legal Secondary Suites
A finished basement is often the most affordable way to add real living space to a home: a family room, a home office, a gym, a guest suite or a playroom. The difference between a basement that feels like part of the house and one that feels like a basement comes down to moisture control, insulation, lighting and ceiling height.
A legal basement apartment, also called a secondary suite or additional residential unit, can bring in rental income, house a family member or help an adult child stay close to home. Ontario's rules now allow additional units in many houses, but a suite is only legal when it is built under a building permit and meets the Ontario Building Code and Fire Code.
Additions and Outdoor Living
An addition gives you space that no renovation inside the existing walls can: a bigger kitchen and family room, a main-floor primary suite, a sunroom, or a second storey over a bungalow. For many families it is the alternative to moving out of a neighbourhood they love.
A good deck extends your living space for half the year and should last for decades. The parts that make that happen are the ones you do not see: footings below the frost line, a properly attached ledger or freestanding frame, correctly sized joists and beams, and hardware rated for outdoor use.
Aging in Place
Most people would rather stay in the home they know than move, and a few well-planned changes often make that possible. Accessible and aging-in-place renovations remove the everyday hazards and barriers that make a house harder to live in: a high tub wall, a narrow doorway, a step at the entrance or a bedroom that is only reachable by stairs.
Renovations 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. We serve Pickering, Ajax, Oshawa, Courtice, Bowmanville, Newcastle, Port Perry and Uxbridge.
Renovations in Scarborough & York Region
Across Scarborough and York Region, families are adding space without moving: finishing basements, adding in-law and rental suites, opening up main floors and updating kitchens and bathrooms in homes built from the 1960s to the 2010s. We serve Scarborough, Markham, Richmond Hill, Vaughan, Stouffville, Aurora, Newmarket and East Gwillimbury.
Renovations in Northumberland & Quinte
Northumberland and the Bay of Quinte have a high share of heritage and century homes alongside newer subdivisions, and many households here are renovating to age in place or to welcome family moving east from the GTA. We serve Port Hope, Cobourg, Brighton, Trenton and Belleville.
Renovations in Peterborough & the Kawarthas
Peterborough and the Kawarthas combine older city neighbourhoods with lake properties and cottages that have become year-round homes, which often need insulation, basement and kitchen upgrades to suit four-season living. We serve Peterborough and Lindsay.
Renovations in South Simcoe & Dufferin
Fast growth in South Simcoe and Dufferin means many newer homes with unfinished basements and builder-grade kitchens and bathrooms, alongside older homes in the historic town cores. We serve Bradford and Orangeville.
Renovations in Hamilton
Hamilton's housing covers almost every era, from century homes and worker cottages to post-war Mountain bungalows and new suburban builds, and its secondary-suite rules have made legal basement apartments one of the most requested projects in the city. We serve Hamilton, Stoney Creek, Ancaster, Dundas and Waterdown.
Renovations in Brant, Haldimand & Norfolk
Along the Grand River and down to Lake Erie, small-town homes, farmhouses and newer subdivisions share the same needs: updated kitchens and bathrooms, finished basements, accessibility upgrades and solid outdoor space. We serve Paris, Caledonia, Dunnville and Simcoe.
Renovations in Cambridge & Oxford County
Cambridge and Woodstock pair stone and brick century homes with large newer subdivisions, giving a steady mix of heritage-sensitive renovations and basement, kitchen and addition projects in younger homes. We serve Cambridge and Woodstock.
