St. John’s North Atlantic exposure makes standard 0.038" vinyl siding effectively unusable — premium-grade vinyl (0.046"+) or fibre cement (James Hardie at $11–$15/sq ft installed) is essentially mandatory for service life beyond 15 years. Hurricane-rated installation specs are now required by most NL insurers. The iconic painted clapboard of Jellybean Row downtown is governed by Heritage Area review for visible material and colour changes. The 15% HST applies, plus 5–10% transport premium on most materials shipped from mainland Canada. Permits clear in 5–15 business days through the Development department.
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.
St. John's, Newfoundland offers affordable renovation costs but faces unique challenges: the limited local contractor pool and the need to ship some specialty materials from the mainland can add to project timelines. The city's iconic colourful row houses in downtown (Jellybean Row) require heritage-sensitive renovations. The oil industry's influence means renovation activity correlates with energy sector health. Expect a smaller but skilled trade workforce.
The City of St. John's issues building permits through its Development department. Residential permits typically take 5–15 business days. The Heritage Area around downtown requires Heritage Advisory Committee approval for exterior changes. Newfoundland and Labrador follows the National Building Code with some provincial amendments.
St. John's has Canada's windiest, foggiest, and wettest major city climate. Annual precipitation exceeds 1,500 mm with 322 cm of snow. Extreme wind gusts (up to 140 km/h) mean roofing and siding must be rated for high-wind conditions. Salt air corrosion is a constant concern for all exterior materials. Basements require aggressive waterproofing.
Newfoundland and Labrador renovations are governed by the National Building Code as adopted provincially, with permits issued by St. John's or the relevant town. Permit review timelines vary widely by municipality — St. John's typically runs 10–20 business days for residential work. Electrical inspections are handled by Service NL.
Newfoundland faces a unique combination of named storm events that other Canadian provinces rarely see at the same frequency — Hurricane Igor (2010), Snowmageddon (January 2020, 76 cm in 24 hours), post-tropical storm Fiona (2022) — that together have shaped local construction practices around extreme resilience. St. John's receives 322 cm of annual snowfall plus regular nor'easter wind events, the highest combined stress of any Canadian provincial capital. Most local insurers now require Class 4 impact-rated shingles plus hurricane-grade installation specs before binding coverage on standard pitched-roof homes. Indoor humidity stays at 65–75% RH year-round in coastal communities, which materially affects flooring and paint selection.
Newfoundland has a small contractor pool with deep weather-driven seasonality — May through October is when most exterior work happens, and winter scheduling for interior projects is common. Material logistics from the mainland can add lead time, so confirm material availability before locking your start date.

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.
The three most common options in Canada: a variable-rate HELOC against your home equity, a fixed-rate renovation loan from your bank (5–10 year terms), or a mortgage refinance if you have substantial equity. For projects under $15,000, a 0% balance-transfer credit card can bridge 12–18 months. Avoid contractor-offered financing — those rates often exceed 12%.
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 St. John's project, DIY can shave 10–20% off the total.
