Most Montreal facades are brick (the iconic plex aesthetic), so siding work usually targets side and rear walls or upper-floor extensions. The Quebec stucco (crépi) tradition persists in 1950s–70s bungalows in Saint-Léonard and Saint-Laurent, but freeze-thaw cycling tends to crack it within 15–20 years — replacement with fibre cement (James Hardie) or modified vinyl is the most common retrofit at $9–$13/sq ft installed. Kaycan, headquartered in Saint-Laurent, dominates Quebec vinyl distribution at $5–$8/sq ft. Heritage zones in Vieux-Montréal and parts of Westmount limit any visible material change without a permis de transformation; suburban boroughs are far more flexible.
Siding replacement is an opportunity to add insulation — house wrap and rigid foam board insulation can be installed during the process, improving your home's energy efficiency by 15–25%. Vinyl siding is the most affordable option but can crack in extreme cold; fiber cement (James Hardie) is the premium choice for Canadian climates, offering superior durability and fire resistance. Get at least three quotes and ask to see completed projects in your neighbourhood.
Material costs vary dramatically: vinyl ($4–8/sq ft installed), engineered wood ($6–12/sq ft), fiber cement ($8–15/sq ft), and natural stone ($15–30/sq ft). The number of windows, doors, and architectural details (soffits, fascia, trim) significantly impacts labour hours and total cost.
💡 Pro Tip
If you're replacing siding, have the contractor inspect the sheathing underneath for rot or damage before installing new material. Catching problems early prevents having to tear off new siding later.
Montreal offers moderate renovation costs compared to Toronto and Vancouver, with a large pool of bilingual contractors. The city's distinctive triplex and duplex architecture means many renovations involve shared walls and multi-unit considerations. Quebec's Régie du bâtiment (RBQ) licensing ensures contractor quality but also means only licensed professionals can perform major work.
Montreal requires permits from the borough (arrondissement) for structural modifications, plumbing, electrical work, and exterior changes. Processing times vary by borough — the Plateau and Ville-Marie are typically slower (3–6 weeks). Quebec law requires all contractors performing work over $5,000 to hold an RBQ licence.
Montreal's extreme temperature range (-10°C in January to 27°C in July) demands high-quality insulation and materials rated for severe freeze-thaw cycles. Snow loads are a key factor for roofing projects, and ice dams are common on older homes without proper attic ventilation.
Quebec renovations are governed by the Code de construction du Québec and overseen by the Régie du bâtiment du Québec (RBQ). Any contractor performing work above $500 must hold a valid RBQ licence — homeowners should verify the licence before signing. Permit timelines vary by municipality, with Montreal boroughs typically faster than smaller MRCs.
Quebec's urban-water story is unusually specific. Montreal and Laval sit in the Rivière des Prairies watershed, where spring runoff floods low-lying neighbourhoods almost every year — Pierrefonds, Pointe-aux-Trembles, Pont-Viau, Sainte-Dorothée — and most home insurers now require both a sump pump and backwater valve before binding flood coverage in those postal codes. Gatineau faces escalating risk from the Ottawa and Gatineau rivers themselves. The City of Montreal's backwater-valve subsidy (up to $5,000) and Laval's equivalent ($4,000) are widely used here in a way that doesn't map cleanly to other provinces.
Quebec contractor capacity is tight in the Montreal–Laval–Gatineau corridor, especially during the short outdoor-work season (May–October). Provincial energy-efficiency programs change frequently; check the official Government of Quebec site (quebec.ca) for the current incentives before assuming any rebate is still active.
In 2026, a siding renovation in Montreal costs between $6,366 (budget) and $33,264 (premium). The average standard cost ranges from $9,093 to $20,790.
Always get three itemized quotes, check provincial licensing (RBQ in Quebec, HCRA in Ontario, equivalent elsewhere), and confirm general liability insurance. Read Google and HomeStars reviews, but weight direct references more heavily — call two past clients. Serious Montreal contractors typically have a 4–8 week backlog; be wary of anyone who can start tomorrow.
A standard siding renovation typically takes 1 to 3 weeks. Premium projects or surprises (structural issues, delivery delays) can extend it. Always get a written schedule from your contractor before signing.
Montreal requires permits from the borough (arrondissement) for structural modifications, plumbing, electrical work, and exterior changes. Processing times vary by borough — the Plateau and Ville-Marie are typically slower (3–6 weeks). Quebec law requires all contractors performing work over $5,000 to hold an RBQ licence.
Demolition, painting, baseboards, and small fixtures are jobs many homeowners take on themselves. Avoid touching plumbing, electrical, or gas without permits and inspection — most municipalities prohibit it, and bad workmanship can void your home insurance. On a typical Montreal project, DIY can shave 10–20% off the total.
