Deck privacy screens in Ottawa fall into three main categories: composite horizontal slat screening, pressure-treated wood slat panels, and privacy lattice. Composite is the lowest-maintenance option for Ottawa's freeze-thaw climate — no staining, no sealing, and a 25 to 30-plus year lifespan matching the deck surface. Composite screening costs $80 to $140 per linear foot installed; pressure-treated wood screening runs $45 to $80 per linear foot.
Ottawa homeowners in Barrhaven, Kanata, Stittsville, and Orleans increasingly add privacy screens to new deck builds as suburban lot density makes outdoor spaces feel exposed. A well-designed horizontal slat screen turns a deck into a usable outdoor room and blocks 70 to 80 percent of sightlines from neighbouring properties. Privacy screens must be roughed into the deck frame at construction — retrofitting to an existing deck costs 30 to 50 percent more than building in from the start. City of Ottawa Zoning By-law 2008-250 governs screening height; screens integrated with the deck guard must meet Ontario Building Code guard requirements.
