How much does it cost to demolish and remove an existing deck in Calgary before building a new one?

Deck demolition and removal in Calgary typically costs $5-15 per square foot, or $1,500-$4,500 for a typical 300-square-foot deck. The wide range depends on the deck's height, structural complexity, material type, and disposal requirements.

Basic ground-level deck removal runs $5-8 per square foot and involves cutting the deck into manageable sections, removing fasteners, and hauling materials to a disposal site. A simple 200-square-foot ground-level deck costs $1,000-$1,600 to remove. Most contractors can complete this in half a day with a two-person crew.

Elevated deck demolition costs $8-15 per square foot due to the additional labour and safety requirements. Working at height requires proper fall protection equipment, and the structural components (posts, beams, joists) are heavier and more time-consuming to disassemble safely. A 300-square-foot elevated deck typically costs $2,400-$4,500 to remove. Multi-level decks with complex railing systems and built-in features like planters or benches are at the upper end of this range.

Material type significantly affects removal costs. Composite and PVC decking is heavier than wood and requires more labour to cut and handle. Exotic hardwoods like ipe are extremely dense and require special cutting blades, increasing both time and tool costs. Decks built with hidden fastener systems take longer to disassemble than face-screwed boards. Older decks with galvanized nails (rather than screws) require more aggressive removal methods.

Calgary-specific considerations include timing and disposal logistics. Deck demolition is best scheduled during the construction season (May through October) when contractors have full crews available and disposal sites are accessible. Winter demolition is possible but may cost 10-20% more due to weather delays and equipment challenges. Calgary's chinook cycles can make winter demo work unpredictable — a job scheduled for -10°C weather might face +5°C and muddy conditions the next day.

Disposal costs vary by material type. Clean wood waste (cedar, pressure-treated lumber) costs $80-120 per cubic metre at Calgary-area disposal facilities. Composite and PVC materials may have higher disposal fees since they can't be recycled as easily as wood. Some contractors include disposal in their quoted price, while others charge it separately. A typical deck generates 3-6 cubic metres of waste, adding $240-720 to the total project cost.

Additional factors that increase demolition costs include difficult site access (narrow gates, steep slopes, landscaping obstacles), the need to preserve adjacent structures or plantings, electrical disconnection for built-in lighting, and hazardous material concerns. Decks built before 1980 may contain lead-based paint or stains, requiring special handling and disposal procedures that can double the removal cost.

DIY demolition can save money but requires proper tools, disposal arrangements, and safety equipment. Rent a reciprocating saw, circular saw, and dumpster (expect $400-800 total). However, elevated deck removal involves significant fall risks and heavy lifting. Most homeowners should hire professionals for decks over 600mm above grade.

Timing with new construction affects overall project efficiency. Most deck builders prefer to handle demolition themselves as part of a full replacement project, ensuring proper site preparation and often providing a small discount on the combined work. Scheduling separate demo and construction contractors can lead to coordination delays and site access issues.

When hiring a professional for deck demolition, verify WCB Alberta coverage and liability insurance. Request a detailed quote that specifies disposal costs, site cleanup, and any electrical disconnection required. Expect the work to take 1-3 days depending on deck size and complexity.
