Renovations made for the way Bowmanville lives.
Bowmanville is Clarington's largest community, with Victorian and early-1900s homes around the historic King Street downtown, established neighbourhoods nearby, and large newer subdivisions on the north and west sides and down toward Port Darlington.
We work across Bowmanville from the historic downtown to Port Darlington, in Victorian and century homes downtown and large newer subdivisions. The projects we are asked about most here are heritage-sensitive renovations of older homes, basement finishing and suites in newer builds, and additions.

What shapes the price of a renovation in Bowmanville
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.

Home Renovations in Bowmanville: Kitchens, Bathrooms, Basements and More
Century and heritage homes in Bowmanville
Bowmanville'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.
1970s to 1990s family homes in Bowmanville
Homes built in Bowmanville from the 1970s to the 1990s are reaching their first full renovation: original oak kitchens, tub-and-tile bathrooms, sunken living rooms and windows at the end of their life. Some of these houses also have materials worth checking before work starts, such as aluminum branch wiring from the late 1960s and 1970s or poly-B plumbing installed from the late 1970s to the late 1990s.
Newer homes built since 2000 in Bowmanville
Newer Bowmanville 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 Bowmanville
A kitchen renovation is one of the most common projects we quote in Bowmanville. The housing here includes Victorian and century homes downtown and large newer subdivisions, and whether the goal is a brighter, more open space or simply more storage and better workflow, the right plan depends on the house.
We handle the whole Bowmanville 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 Bowmanville
Bathroom renovations are a steady part of our work in Bowmanville, from Downtown Bowmanville and Port Darlington to the rest of the area. The most common requests are walk-in showers, tub-to-shower conversions, double vanities and basement bathrooms.
Every Bowmanville 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 Bowmanville
Plenty of Bowmanville homes, from Downtown Bowmanville and Port Darlington to the rest of the area, have a basement that is unfinished or finished decades ago. Either way, it is usually the cheapest square footage in the house to turn into real living space.
Every Bowmanville 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 Bowmanville
Demand for legal basement apartments in Bowmanville is strong, whether for rental income, a parent moving closer or a young adult who wants their own space. Many Victorian and century homes downtown and large newer subdivisions in Downtown Bowmanville, Port Darlington and Bowmanville West have basements well suited to a secondary suite.
Secondary suites in Bowmanville are approved by the Municipality of Clarington, 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 Bowmanville
In Bowmanville, an addition is often the answer for families who love their street in Downtown Bowmanville and Port Darlington but have outgrown the house. With Victorian and century homes downtown and large newer subdivisions, rear additions, second storeys and main-floor suites are all common.
Accessible Renovations in Bowmanville
Many Bowmanville homeowners want to stay in the neighbourhood they know, in Downtown Bowmanville, Port Darlington and Bowmanville West 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.
