Deck building in Montreal.

Montreal, with 1.78 million residents, is Canada's second-largest city and Quebec's deck building hub. All deck contractors in Quebec must hold a valid RBQ (Régie du bâtiment du Québec) licence — working with an unlicensed contractor is illegal and voids insurance. Montreal's winters are harsh: frost line depth reaches 1.5m (5 feet) and annual snowfall exceeds 200 cm. The city's signature outdoor staircases and balconies (Montreal's iconic triplex architecture) create unique deck and railing opportunities. Labour costs average $20–$28 per sq ft, with composite growing rapidly in Plateau, Mile End, and suburban Laval.

Deck Building in Montreal

Planning a deck build in Montreal? Our local BestDecks crew handles the whole job — permits, engineered deck footings set below the 1.5m (5 feet) regional frost line, material sourcing, and the full build under one fixed-price contract. Decks over 24 inches above grade need a municipal permit and we pull it for you. Book late winter or early spring to lock in your crew before peak season — our 24-hour quote turnaround and 25-year BestDecks warranty mean you can commit with confidence.
