Deck projects offer excellent outdoor living value in Canadian summers but material choice dramatically affects longevity and maintenance. Pressure-treated wood is cheapest upfront ($15–25/sq ft installed) but requires annual staining. Composite decking ($30–55/sq ft) costs more but lasts 25–50 years with minimal maintenance. Plan for proper footings below the frost line — in most Canadian cities, that's 4–5 feet deep.
Material choice is the #1 cost driver: cedar ($25–40/sq ft), composite ($30–55/sq ft), or exotic hardwoods like Ipe ($50–80/sq ft). Railings add $50–120 per linear foot. Multi-level decks cost 50–75% more than single-level. Built-in features like benches, planters, and pergolas add $2,000–$10,000.
💡 Pro Tip
Build your deck in fall or early spring when contractors are less busy — you can often save 10–15% on labour and have it ready for summer use.
Laval offers renovation costs 5–10% lower than neighbouring Montreal, with easier contractor scheduling and less competition for skilled trades. The city's predominantly post-1960s housing stock — many bungalows, split-levels, and early condos — is now entering its first or second major renovation cycle. Laval homeowners benefit from Quebec's large network of RBQ-licensed contractors and competitive material pricing from big-box stores clustered along the autoroutes.
Laval issues permits through its Service de l'urbanisme. Residential permits typically take 5–15 business days depending on complexity. As in all of Quebec, contractors must hold an RBQ licence for work exceeding $5,000. Laval's urban planning regulations are generally more flexible than Montreal's, especially for suburban properties.
Laval shares Montreal's cold continental climate with harsh winters (-10°C average in January) and warm, humid summers. The city's flat terrain and proximity to the Rivière des Prairies means some areas are prone to spring flooding — basement renovations should include sump pump installation and proper waterproofing.
In 2026, a deck renovation in Laval costs between $7,700 (budget) and $40,800 (premium). The average standard cost ranges from $11,000 to $25,500.

A deck renovation typically yields a 65–75% return on investment at resale in Canada. ROI depends on material quality, the local real estate market in Laval, and the property's condition.
