Working With Wood builds decks in Niagara Falls and serves the wider Niagara Region, including Port Colborne. Ballpark ranges only, not a quote: Niagara Falls-area deck projects commonly land around $8,850 (range $4,200-$18,600), while larger builds across the wider Niagara Region can run $15,000-$35,000, and professional deck upgrades in Niagara 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). 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.
Under the Ontario Building Code, a deck generally needs a building permit if it is larger than 10 m2 (about 108 sq ft), OR more than 60 cm (about 24 inches) above grade, OR attached to the house. Below all three thresholds it is often permit-exempt, but zoning setbacks can still apply either way. Niagara Falls, St. Catharines, and Niagara-on-the-Lake each administer their own building department, so always confirm the current rule with your specific municipality before you build. Separately: adding a permanent or solid roof over a deck is treated differently from an open deck. A permanent cover generally brings the project back into building-permit review (snow-load, wind-load, and setback considerations), even if the deck itself would otherwise be exempt. We have not confirmed a Niagara-specific snow-load figure for that review, so we state the principle only. Confirm engineering and permit specifics for any covered/roofed deck with your municipality.
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 here. Homeowners often see the higher composite cost break even against wood's maintenance costs somewhere around the 8-10 year mark, though that depends on how diligently a wood deck is maintained. Neither material is a wrong choice: it is a tradeoff between lower upfront cost plus more upkeep (wood) versus higher upfront cost plus less upkeep (composite).
Ballpark, Niagara Falls-area deck projects commonly land around $8,850 (range $4,200-$18,600), while larger builds across the wider Niagara Region can run $15,000-$35,000, with per-square-foot pricing typically $35-$75/sq ft locally ($45-$95/sq ft Ontario-wide depending on material). These are wide ranges, not a quote. Book an estimate for a number specific to your project.
Usually yes if the deck is bigger than 10 m2 (about 108 sq ft), more than 60 cm (24 in) above grade, or attached to the house. Confirm with your municipality (Niagara Falls, St. Catharines, and NOTL each run their own building department) since the exact application of these rules can vary.
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. Higher composite cost often breaks even against wood's maintenance cost around 8-10 years.
Ontario builders commonly describe a general pattern of about 6-10 weeks from first call to a finished deck, though this varies by project size, permitting, and time of year. Ask for a timeline specific to your build.
Yes, composite is built to handle repeated freeze-thaw cycling, and Ontario sees roughly 40-60 such cycles a year. That durability is a core reason composite costs more upfront than wood.
Generally yes, a permanent or solid roof over a deck typically brings the project back into building-permit review for snow-load, wind-load, and setback reasons, even if the open deck underneath would otherwise be exempt. Confirm the specifics with your municipality before building.
Ontario deck builders commonly describe a general first-call-to-finished-deck pattern of about 6-10 weeks: a useful expectation-setter, not a Working With Wood-specific promise; ask for a timeline for your own project.
