Carpentry covers a huge range in Ottawa, from the rough framing that holds a house up to the finish trim that makes a room feel finished. Homeowners often lump it all together, but the two ends of the trade require very different skills: a framer works to structural tolerances and the Ontario Building Code, while a finish carpenter works to the eye, hiding gaps, matching profiles, and delivering crisp mitres in rooms that are rarely perfectly square. Ottawa's older housing stock in Centretown, the Glebe, and Sandy Hill makes finish work especially demanding, because century plaster walls, sett...
Carpentry in Ottawa breaks into two broad categories with a lot of overlap. Rough carpentry is structural and hidden: wall framing, floor and roof systems, subfloors, basement partition walls, deck structures, and structural repairs to sagging joists or rotted sills common in older homes. Finish carpentry is what you see and touch: baseboards, casings, crown moulding, wainscoting, coffered ceilings, stair parts, interior doors, and custom built-ins like bookcases, window seats, mudroom lockers, ...
Custom built-ins are where finish carpenters add the most value in Ottawa homes, and where the price range is widest. Built-in bookshelves, entertainment units, banquette seating, mudroom cubbies, and window benches transform awkward nooks that suburban Kanata and Barrhaven homes often have around f...
Carpentry pricing in Ottawa varies more than almost any other trade because the work ranges from rough framing to fine millwork. In 2026, skilled carpenter labour generally runs $55–$95 per hour, with finish carpenters and experienced cabinetmakers at the top of that range. Baseboard and casing installation is often priced at $3–$8 per linear foot for labour, while crown moulding runs $6–$14 per linear foot because it requires compound mitres and often two people. Installing interior doors avera...
The workflow depends on whether the job is rough or finish. Rough carpentry — framing a basement, building a partition, or repairing structure — starts with layout, then framing, then inspection if a permit applies, before other trades and drywall follow. Finish carpentry comes near the end of a renovation, after paint primer and flooring in many cases, so the trim sits on finished surfaces. A finish carpenter measures and templates, mills or orders trim, then scribes and installs, filling nail ...
Finish carpentry — trim, doors, built-ins, wainscoting — is cosmetic and requires no City of Ottawa permit. Rough carpentry is a different matter. Any work that alters structure, adds or removes load-bearing walls, frames a basement into living space, or changes the building's layout typically requires a City of Ottawa building permit and inspection, and structural changes may need an engineer's stamp. Removing a wall you assume is non-load-bearing without verification is one of the most common ...
Match the carpenter to the work. For custom built-ins and fine trim, hire a finish carpenter or cabinetmaker and judge them on their portfolio — look closely at mitre joints, scribe lines against walls, and how consistent reveals are around doors and windows. For structural or framing work, prioritize someone who understands the Ontario Building Code and works comfortably with permits and inspectors. In every case, confirm at least $2 million in general liability insurance and a valid WSIB clear...
Carpentry offers several honest ways to save. Choosing paint-grade MDF trim instead of stain-grade hardwood cuts material cost substantially and, once painted, looks excellent in most Ottawa homes — stain-grade is worth the premium only where you want visible wood grain. Simpler profiles install faster than ornate multi-piece build-ups, so a clean modern baseboard costs less than a layered Victorian reproduction. For built-ins, a hybrid approach — using stock cabinet boxes as the base and adding...
Skilled carpenter labour typically runs $55–$95 per hour. Baseboard and casing install around $3–$8 per linear foot, crown moulding $6–$14 per linear foot, and interior doors $150–$350 each. Custom built-ins are quoted per project, from $800 for a closet organizer to $10,000-plus for a full library wall.
Rough carpentry is structural and hidden — framing walls, floors, roofs, and decks to code tolerances. Finish carpentry is visible detail work — baseboards, casings, crown moulding, stairs, doors, and custom built-ins. They require different skills, so match the carpenter to the job: a great framer is not automatically a great trim carpenter.
Finish carpentry like trim and built-ins needs no permit. Structural work — removing load-bearing walls, framing a basement into living space, or altering layout — usually requires a City of Ottawa building permit and inspection, and may need an engineer's stamp. Never remove a wall without confirming whether it is load-bearing.
A room of new baseboards can be a single day, crown moulding across a main floor two to four days, and larger custom built-ins one to three weeks including shop build time. Custom millwork adds one to three weeks of lead time for the cabinetmaker to build components before on-site installation.
Paint-grade MDF is cheaper, stable, and looks excellent once painted, making it the practical choice for most Ottawa homes. Stain-grade hardwood is worth the premium only where you want visible wood grain. Whatever you choose, let the material acclimate indoors for several days before installation to prevent gaps.
