Hiring the right general contractors in Kingston shouldn't be a gamble. Below are local general contractors serving Kingston and the surrounding area, sorted by customer rating — or by distance from you if you allow location access. Every listing links straight to the business, so you contact them directly. No lead fees, no middlemen, no spam.
Get at least three written quotes that break down labour, materials and timeline separately, so you can actually compare them. Confirm WSIB coverage and liability insurance, and ask for recent local references you can call. Be wary of a quote far below the others -- it usually means something has been left out, and you will meet it again as a change order.
Costs vary enormously with scope, finishes and how much of the existing structure has to change. The reliable pattern is that anything involving moving plumbing, altering structure, or opening up walls in an older home costs more than the equivalent work in newer construction, because of what gets found once the walls are open. Build a contingency of at least 10 to 15 percent into your budget for older homes.
Structural changes, additions, new or moved plumbing, decks above a certain height, finishing a basement and altering means of egress generally require a permit from the City of Kingston. Cosmetic work such as paint, flooring and cabinet replacement generally does not. Your contractor usually pulls the permit; confirm in writing who is responsible, and never accept an offer to skip one.
Kingston has a large stock of designated heritage properties and heritage conservation districts, particularly in Old Sydenham. Designation can restrict changes to the exterior appearance, windows and materials, and may require a heritage permit in addition to a building permit. Work with a contractor who has done designated properties here before -- the approvals process is a real part of the timeline.
A reasonable deposit to secure a start date and order materials is normal. Paying a large share of the total before meaningful work has happened is not. Tie payments to defined milestones in the written contract, keep a holdback until deficiencies are fixed, and pay by a traceable method rather than cash. Under Ontario consumer protection rules, contracts signed in your home also carry a cooling-off period.
