Renovations made for the way Ajax lives.
Ajax grew from a wartime town into a busy lakeshore community, with older homes south of the 401, established family neighbourhoods in central Ajax and newer subdivisions in the north and west.
We work across Ajax from the waterfront to Northwest Ajax, in wartime-era homes, established family homes and newer subdivisions. The projects we are asked about most here are basement finishing and secondary suites, kitchen and bathroom remodels and open-concept main floors.

Investment
What shapes the price of a renovation in Ajax
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 Ajax: Kitchens, Bathrooms, Basements and More
Post-war bungalows and back-splits in Ajax
The post-war bungalows and back-splits in Ajax 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.
1970s to 1990s family homes in Ajax
Homes built in Ajax 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 Ajax
Newer Ajax 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 Ajax
A kitchen renovation is one of the most common projects we quote in Ajax. The housing here includes wartime-era homes, established family homes and 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.
Our Ajax kitchen projects follow a clear sequence: measure and plan, order long-lead items like cabinets, then demolition, rough-ins and inspections, followed by drywall, cabinets, counters, tile and finishing. You get one point of contact from start to finish.
Bathroom Renovations in Ajax
Bathroom renovations are a steady part of our work in Ajax, from Pickering Village and South Ajax to the rest of the area. The most common requests are walk-in showers, tub-to-shower conversions, double vanities and basement bathrooms.
Our Ajax bathroom remodels are fully managed: demolition, repairs, plumbing, electrical, waterproofing, tile, glass, fixtures and finishing, with a written schedule so you know how long the room is out of use.
Basement Finishing in Ajax
Plenty of Ajax homes, from Pickering Village and South Ajax 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.
We finish Ajax basements from bare concrete to move-in ready: insulation, framing, bathrooms, wet bars, laundry, pot lights, drywall, flooring and trim, with the permit and inspections handled.
Legal Basement Apartments in Ajax
In Ajax, homeowners are adding legal secondary suites to help with the mortgage and to keep family close. The key is building one properly, with a permit, so the unit is safe, insurable and adds value when you sell.
Before we quote a Ajax basement apartment, we confirm the Town of Ajax's requirements for your property. Then we plan fire separation, egress windows, the entrance, alarms, the suite kitchen and bathroom, and the permit, so the unit is legal from day one.
Home Additions in Ajax
Ajax homeowners add space with rear and side additions, second storeys over bungalows and four-season sunrooms, especially where wartime-era homes, established family homes and newer subdivisions sit on lots with room to grow.
Accessible Renovations in Ajax
In Ajax, where homes include wartime-era homes, established family homes and newer subdivisions, accessibility upgrades range from a single curbless shower to moving a bedroom and laundry to the main floor so the stairs become optional.
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.
