Wooden decks can add space to any home, allowing owners to enjoy the outdoors in comfort or to store items. However, when it comes to building wooden decks in northern Canada, it’s important to understand how the climate can affect the longevity of the structure. These decks face some of the harshest conditions:
- long winters
- heavy snowfall
- ice buildup
- freeze-thaw cycles
- intense summer sunlight.
These stresses cause wear and tear over time, requiring regular maintenance and occasional renovations to ensure the structure remains safe and functional. Homeowners with older decks should anticipate various types of renovation work, ranging from minor surface repairs to extensive rebuilding https://www.commercial-nds.com/our-services/deck-builders/, depending on the deck issue:
Wood deterioration
Moisture from snow and ice can penetrate untreated or aging boards, leading to rot and decay. In such cases, replacing the damaged planks or sections of the substructure becomes necessary. If the rot is widespread, a more substantial renovation may be required, including replacing joists and support posts, to ensure safety.
Fasteners and hardware problems
In cold climates, metal components can rust or loosen as the wood expands and contracts. Renovation often involves replacing nails with corrosion-resistant screws or upgrading to galvanized or stainless steel hardware. This improves the deck’s durability and stability.
Foundation damage
The freeze-thaw cycle can affect a deck’s foundation, as posts anchored in the ground may heave upward as the soil expands with frost. Over time, this can destabilize the structure, resulting in uneven or sloping surfaces. Repairing this type of damage often requires resetting or replacing footings with deeper foundations or concrete piers designed to resist frost movement.
Surface refinishing
Wooden decks exposed to intense UV rays in the summer quickly lose their protective finish, which can lead to cracking, splintering, and fading. Renovation may include sanding the boards, applying a sealant, or staining them with weather-resistant products formulated for extreme climates. This restores the deck’s appearance and extends its lifespan.
Railings and stairs safety
Railings and stairs endure constant stress from use and are particularly susceptible to moisture damage. When renovating an old deck, it is often necessary to reinforce or replace these elements to meet safety codes. Some homeowners choose to upgrade to composite or metal railings, which require less maintenance in harsh conditions.
Insulation works
According to safety standards, the area where the deck connects to the house should be flashed to prevent water damage. Over time, this area can deteriorate, allowing water to seep into the siding or framing. Renovation may involve repairing or installing new flashing to prevent structural damage to the deck and home.
In northern Canada’s climate, deck renovations are rarely just cosmetic. It usually includes structural reinforcement, replacing deteriorated components, and taking protective measures against weather extremes. These measures ensure the deck will remain safe, functional, and enjoyable for years to come.
