Pergola Installation Cost
Pergola pricing changes sharply between a small prefabricated kit, a custom wood structure, and a louvered or motorized roof system. Define the structure before comparing totals.
What the quote may include
Separate the pergola kit or custom frame, posts, footings or anchoring, attachment to a building or deck, site preparation, leveling, roof or louver system, electrical work, fans or lighting, access, removal, finish, design, and approvals. A product that moves or drains like a roof needs a different evaluation from an open slatted frame.
Angi’s 2026 U.S. summary reports roughly USD 2,118–6,433 for professional pergola installation. HomeGuide reports different prefab and custom signals. These sources are directional, method-dependent, and not Canadian estimates. Use local bids for Canadian work.
Kit versus custom
Kits may reduce fabrication but still require a suitable base, anchoring, assembly, access, and product-specific instructions. Custom work may fit a slope or existing deck better but add design and engineering. Motorized louvers add controls, wiring, drainage, maintenance, and safety considerations.
Site and exposure
Wind, snow, corrosion, slope, tree removal, and proximity to the house affect the design. Canadian WUI guidance treats nearby outdoor attachments as hazard-specific recommendations based on construction class and distance; it is not a universal pergola code.
Quote questions
Ask for the exact system, foundation, attachment, roof behavior, electrical, drainage, maintenance, warranty, and local approval assumptions. Do not use a generic span or anchoring detail to approve a structure.
