Follow these key steps recommended by building experts to extend the lifespan of your balcony and railings.
1. Perform a deep clean before the freeze. Before the cold sets in, clean the surface of your deck (whether it is fiberglass, composite, or aluminum). Use a soft-bristled broom and a mild, biodegradable soap. Remove fallen leaves and debris accumulated in the corners. Standing moisture trapped under the snow can cause stubborn stains or promote mold growth.
2. Inspect the structure and stability of the railings. Take a few minutes to check the general condition of your balcony railings and structural fasteners: Ensure that screws and wall anchors are tight. The weight of the snow will exert significant lateral pressure on your railings. Examine the sealant joints around the posts and where the structure meets the house. Cracked sealant allows water to seep in; as it freezes, the water expands and can cause materials to crack or burst.
3. Be careful with de-icing products and salt. This is the most common mistake: using traditional de-icing salt (sodium chloride) can severely damage concrete, compromise the protective finish on fiberglass, and accelerate corrosion on untreated metal parts. A safe alternative: Opt for sand or fine gravel to provide traction without damaging the materials. If you absolutely must melt the ice, choose magnesium chloride-based products, which are much gentler on exterior surfaces.
4. Use the right tools for snow removal. When clearing your deck or steps, strictly avoid metal shovels. They can permanently scratch fiberglass or damage the architectural paint finish on aluminum railings. Always use a plastic shovel without a metal edge and handle it carefully near joints and glass panels.
5. Observe safety standards at all times. A balcony damaged by winter can pose a major safety risk to your family. In Quebec, structures must meet strict requirements. Ensure that your installations remain compliant with current regulations.
