Trim & Finish Carpentry
Crown Moulding & Cornice Installation
The short answer
Crown moulding is trim installed at the junction of wall and ceiling, running at an angle to both. It suits rooms with 9ft ceilings or higher and can overwhelm a standard 8ft room unless the profile is kept modest. Installation is technically demanding because crown sits on a compound angle, ceilings are rarely flat, and every inside corner should be coped rather than mitred.

Where crown belongs — and where it does not
Crown moulding is not a universal upgrade. It works when a room has the height to carry it and an architectural language that suits it, and it looks forced when it does not.
It belongs in principal rooms with 9ft ceilings or higher — living rooms, dining rooms, primary bedrooms, studies. It works well in traditional and transitional interiors and in the taller main floors of Calgary’s inner-city infills and estate homes.
It is usually wrong in rooms with 8ft ceilings unless the profile is very restrained, in most basements, in strictly minimalist interiors where the design intent is a clean ceiling junction, and in rooms with vaulted or sloped ceilings where the geometry becomes tortured. In those situations we will say so rather than take the work.

Crown styles
- Simple cove
- A concave single profile. Restrained, affordable, and the safest choice for 8ft ceilings.
- Traditional crown
- The classic profile with ogee and fillet detail. Suits 9ft ceilings and traditional interiors.
- Built-up cornice
- Two or three components combined to create a deeper, more substantial cornice. Appropriate in 10ft rooms and formal spaces.
- Square / stepped modern
- Rectilinear profiles with no curves. Suits contemporary interiors where a traditional ogee would look out of place.
- Crown with light cove
- A built-up assembly with a concealed channel for LED, washing light up the ceiling. Effective in rooms with height.
Answers
Frequently asked questions
- Can I put crown moulding on 8ft ceilings?
- Yes, but keep the profile small — a simple cove or a modest crown of around 75–100mm. Large built-up cornices in an 8ft room visually lower the ceiling and make the space feel compressed. In many 8ft rooms a taller baseboard is a better investment than crown.
- Should crown moulding match my baseboard?
- They should be compatible in style and proportion but they do not need to be the same profile. A common approach is a slightly smaller crown than baseboard in the same design language. What looks wrong is a heavily traditional crown with a flat modern baseboard, or vice versa.
- Does crown moulding work with vaulted ceilings?
- It is difficult and often not worth it. Where a sloped ceiling meets a flat wall the crown runs at a changing compound angle, and the transitions at the corners are awkward to resolve. Sometimes a flat trim board or simply no trim is the better answer. We will assess the specific geometry before recommending it.
- How much does crown moulding cost?
- It is priced by linear foot and depends heavily on the profile — a simple single-piece cove is much less than a three-part built-up cornice, which takes considerably more labour. Room complexity matters too: many corners, high ceilings requiring staging, and out-of-square walls all add time. We quote per room after measuring.
- Can crown moulding be installed in a room with a bulkhead?
- Yes, and it often helps — running crown around a bulkhead makes it read as an intentional architectural feature rather than a duct enclosure. The detailing at the corners takes care, but the result usually improves how the bulkhead looks considerably.
