How much does a patio privacy wall or screen cost in Ottawa?

Patio privacy walls and screens in Ottawa range from about $1,500 for a simple cedar fence panel section to $15,000 or more for a full-length engineered stone wall with integrated features. The cost depends on material, height, length, and whether the structure needs its own foundation to resist Ottawa's frost heave and wind loads. Most homeowners spend between $3,000 and $8,000 to screen one or two sides of their patio effectively.

Wood privacy screens are the most common and affordable option. A pressure-treated or cedar screen wall, typically six feet tall with horizontal slat construction, runs $40 to $80 per linear foot installed including posts set in sono tubes below frost line. For a 20-foot run along one side of your patio, that's $800 to $1,600 for the screen itself plus $600 to $1,200 for the post footings. Cedar naturally resists rot and looks attractive, but in Ottawa's climate it needs staining or sealing every two to three years to maintain its appearance, adding roughly $3 to $5 per linear foot in ongoing maintenance. Pressure-treated lumber costs 30-40% less upfront but doesn't age as gracefully without consistent maintenance.

Composite and PVC privacy screens from brands like Trex, Fiberon, or SimTek offer a low-maintenance alternative at $80 to $150 per linear foot installed. SimTek's moulded stone-look fence panels are particularly popular in Ottawa because they resist wind, require zero maintenance, and mimic the look of stacked stone at a fraction of the weight. A 20-foot composite privacy screen runs $1,600 to $3,000 for the panels and hardware, plus the same footing costs as wood. The higher upfront cost pays back within five to seven years through eliminated staining and replacement expenses.

Masonry privacy walls built from paver wall blocks, natural stone, or poured concrete are the most substantial and permanent option. A six-foot-tall wall built from Techo-Bloc Mini-Creta or Unilock Rivercrest wall blocks costs $120 to $200 per linear foot installed, including the concrete footing that's essential for any masonry wall in Ottawa. That footing must extend below the 1.2 to 1.5-metre frost line and be reinforced with rebar, which alone costs $80 to $150 per linear foot for the excavation, forming, and pour. A 16-foot masonry privacy wall runs $3,200 to $5,600, making it the most expensive per-foot option but also the most durable and wind-resistant.

For walls over four feet tall, or any masonry wall, the Ontario Building Code may require engineering documentation and a building permit from the City of Ottawa. Engineered retaining walls and freestanding walls over 1.0 metre above grade almost always trigger permit requirements, so factor $300 to $600 for the permit and $500 to $1,500 for engineering drawings if your design falls into that category. Skipping the permit isn't worth the risk since the city can require you to remove unpermitted structures, and they definitely will if a neighbour complains.

Living privacy screens using columnar evergreens like Emerald Cedar or Brandon Cedar planted in raised beds along the patio edge offer a softer, natural look at $50 to $100 per tree for 5 to 6-foot specimens, plus $500 to $1,500 for the raised bed construction. However, these take three to five years to fill in to full screening density and are vulnerable to Ottawa's heavy ice storms, which can snap branches and create permanent gaps. Many homeowners combine a partial hard screen with plantings for a layered approach that provides immediate privacy with growing character over time.
