How much does it cost to frame and drywall a Calgary basement?

Framing and drywalling a Calgary basement typically costs between $7,000 and $20,000 combined for a standard 800 to 1,200 square foot space, making it one of the largest single cost components in any basement development. Framing alone runs $2.50 to $5.00 per square foot of wall area, and drywall installation with taping and finishing adds $2.50 to $4.00 per square foot — but the total depends heavily on your layout complexity, ceiling height, and number of rooms.

For framing, the standard approach in Calgary basements is 2x4 wood stud walls built approximately 1 inch off the foundation wall. This gap is critical — it prevents direct contact between the wood framing and cold, potentially damp concrete. A simple open-concept basement with one or two bedrooms, a bathroom, and a living area might have 300 to 500 linear feet of wall to frame. The more rooms and hallways you create, the more framing material and labour you need. A straightforward layout in an 800 square foot basement might cost $3,000 to $5,000 for framing, while a complex layout with multiple rooms, closets, a bathroom, and utility room enclosures in a 1,200 square foot space could run $6,000 to $10,000.

One Calgary-specific framing consideration is insulation integration. The Alberta Building Code requires a minimum of R-20 for below-grade walls, and the insulation strategy directly affects your framing approach. If you are using 2 inches of closed-cell spray foam ($3.00 to $5.00 per square foot) against the foundation before framing, the stud cavities can be filled with fiberglass or mineral wool batts to exceed R-20 comfortably. If you are using XPS rigid foam board against the concrete, it needs to be installed before framing goes up. Your framing contractor and insulation contractor need to coordinate — framing before insulation or insulation before framing depends on the method chosen.

Drywall costs in Calgary run $2.50 to $4.00 per square foot installed, taped, mudded, and sanded to a paint-ready finish. For basement bathrooms, use moisture-resistant drywall (green board at $18 to $26 per 4x8 sheet) or mould-resistant drywall (purple board at $22 to $30 per sheet). Standard half-inch drywall is fine for all other areas. The level of drywall finish matters — Level 4 finish (standard for painting) costs less than Level 5 finish (skim coat, needed for glossy paints or critical lighting). Most basement contractors deliver Level 4 as their standard.

Ceiling drywall adds cost and complexity. Drywall ceilings give a clean, finished look but permanently cover plumbing, electrical, and ductwork above — any future repairs require cutting access holes. Drop ceilings at $4.00 to $8.00 per square foot provide easy access but reduce ceiling height by 3 to 6 inches, which can be problematic in older Calgary homes where basement ceilings are already tight at 7 feet. If your ceiling height is borderline (approaching the Alberta Building Code minimum of 6 feet 5 inches for existing homes), every inch matters, and drywall directly to the joists preserves the most headroom.

Always confirm your contractor carries WCB Alberta coverage before work begins — without it, you as the homeowner could be liable for workplace injuries on your property. Find qualified basement framing and drywall professionals through the Calgary Construction Network directory.
