Working With Wood builds decks in Niagara Falls -- our home service area. Ballpark ranges only, not a quote: Niagara Falls-area deck projects commonly land around $8,850, with a typical range of $4,200-$18,600, and professional deck upgrades in the Niagara area trend $35-$75/sq ft. Ontario-wide, installed decks generally run $45-$95/sq ft (pressure-treated wood $45-65/sq ft, composite $65-95/sq ft) if you want a wider anchor. These are wide, self-serving 2026 marketing-content ranges, not a fixed price. Your actual cost depends on size, height, site access, and material. Book a real estimate for a number you can rely on.
Niagara Falls requires a building permit for a deck if any one of four things is true: the deck is bigger than 10 m2 (about 108 sq ft), it is more than 60 cm (23 5/8 in) above grade measured from the top of the walking surface, it is covered or roofed, or it is attached to the house. Meeting any single trigger means a permit is required. Niagara Falls asks for a site plan (1:200 scale, showing lot lines and setbacks), a floor plan, and cross-section/elevation drawings, and requires three inspections: footing/excavation before any concrete is poured, framing, and final. Building department: 905-356-7521 ext. 4330, pbd@niagarafalls.ca. If you are comparing this against a nearby municipality (St. Catharines, Niagara-on-the-Lake, or Welland each set their own rule), see the Niagara deck permit guide for the full side-by-side. As always, confirm the current rule directly with Niagara Falls' building department before you build.
Wood (typically pressure-treated) costs less upfront and gives a natural look, but in Ontario's climate it needs re-staining or sealing roughly every 1-2 years and has a shorter service life before boards need replacing. Composite decking costs more upfront but needs little to no annual finishing and holds up well against Ontario's 40-60 freeze-thaw cycles per year, which is the real stress test for any outdoor deck material in the Niagara Falls area, not just a general climate note. Homeowners often see the higher composite cost break even against wood's maintenance cost somewhere around the 8-10 year mark, though that depends on how diligently a wood deck is maintained. Neither material is a wrong choice for a Niagara Falls deck: it is a tradeoff between lower upfront cost plus more upkeep (wood) versus higher upfront cost plus less upkeep (composite). For the full pressure-treated-versus-composite pricing breakdown, see the decking material guide.

Wood costs less upfront but needs re-staining/sealing every 1-2 years and wears faster. Composite costs more upfront but needs little annual upkeep and holds up well against Ontario's 40-60 freeze-thaw cycles a year, the real stress test for a Niagara Falls deck. Higher composite cost often breaks even against wood's maintenance cost around 8-10 years.
