Interior Renovation in Ontario

Interior renovation pulls several finishing trades into one scoped project: trim and moulding, interior doors, wall panelling, built-in millwork and the transitions between floors and rooms. Rather than booking each trade separately, a contractor sequences the work so surface preparation happens before trim goes on, trim before paint, and hardware last. For Ontario homeowners this is usually the stage after structural or mechanical work is closed in, and it is the stage where precision matters more than horsepower.

Much of the province's housing stock is decades old, and older framing is rarely straight. Good finish carpenters expect out-of-true walls and out-of-level floors, and they scribe trim and cabinetry to follow them rather than leaving gaps for caulk to hide. Material choices run through the whole project too. Paint-grade MDF gives crisp profiles at a lower cost, poplar takes paint well and handles knocks better, and stain-grade oak or maple costs more but shows real grain. Picking one standard early keeps every room consistent.

A useful quote starts with a walk-through, not a phone estimate. Contractors will measure each room, note which walls need levelling or backing, and confirm which elements you want designed and built versus bought and installed. Expect the written quote to break out materials, labour and finishing as separate lines so you can compare tiers between contractors instead of judging a single lump figure.

• Room-by-room scoping walk-through with measurements and a written work list
• Removal and disposal of dated trim, doors and finishes
• Surface preparation, wall levelling and backing where new millwork lands
• Supply and installation of baseboard, casing, doors and panelling to an agreed spec
• Built-in millwork designed, built and installed to fit the actual room
• Caulking, filling and sanding to a paint-ready or pre-finished standard
• Coordination of painting and flooring transitions so trades land in the right order
• Final walk-through against the scope list before sign-off

• Number of rooms in scope and how much existing finish has to come out first
• Condition of the walls and floors, since out-of-true framing adds scribing and levelling time
• Material tier: paint-grade MDF, poplar, or stain-grade hardwood
• Amount of custom millwork versus stock profiles and off-the-shelf doors
• Ceiling height, since taller rooms mean larger profiles and more ladder work
• Whether painting is included or handled by a separate painter
• Access and occupancy, because working around furniture in a lived-in home slows every trade
