Investment
What shapes the price of a renovation in Newmarket
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 Newmarket: Kitchens, Bathrooms, Basements and More
Century and heritage homes in Newmarket
Newmarket'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 Newmarket
Homes built in Newmarket 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 Newmarket
Newer Newmarket 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 Newmarket
In Newmarket, homeowners from Historic Main Street and Glenway 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 Newmarket 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 Newmarket
Whether it is a main bath in Historic Main Street or a new basement bathroom anywhere in Newmarket, we plan the layout, the plumbing and the waterproofing first, then the finishes you will see every day.
Every Newmarket 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 Newmarket
Newmarket 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 Newmarket 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 Newmarket
Demand for legal basement apartments in Newmarket is strong, whether for rental income, a parent moving closer or a young adult who wants their own space. Many established family homes and newer subdivisions in Historic Main Street, Glenway and Stonehaven have basements well suited to a secondary suite.
Secondary suites in Newmarket are approved by the Town of Newmarket, 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 Newmarket
In Newmarket, an addition is often the answer for families who love their street in Historic Main Street and Glenway but have outgrown the house. With established family homes and newer subdivisions, rear additions, second storeys and main-floor suites are all common.
Accessible Renovations in Newmarket
Many Newmarket homeowners want to stay in the neighbourhood they know, in Historic Main Street, Glenway and Stonehaven and beyond, and the right changes to the bathroom, entrances and main floor make that safer and easier.
Renovating 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.
