How to Winterize Your Composite Deck Before Ontario’s First Frost

October 15, 2025

As brisk winds and chilly evenings settle over Woodstock and the surrounding areas, Ontario homeowners know that the first winter frost is just around the corner. If you’ve invested in a beautiful composite deck from Baird Construction, now is the time to ensure it stays pristine and functional through the colder months. Proper winterization not only protects your outdoor investment but also extends the lifespan and maintains the value of your deck. Here’s your step-by-step guide to winterizing your composite deck before Ontario’s first frost hits.


Why Winterizing Your Composite Deck Matters in Ontario


Ontario winters are notorious for fluctuating temperatures, snow accumulation, and icy conditions. Composite decking is designed for durability and low maintenance, but seasonal preparation is still essential to prevent damage from freeze-thaw cycles, moisture, and debris. By winterizing your composite deck, you safeguard its aesthetic appeal, structural integrity, and create a welcoming space ready to enjoy again when spring arrives.


Essential Steps for Winterizing Your Composite Deck


Follow these best practices to prepare your composite deck in Woodstock or anywhere in Ontario for winter’s challenges:


Clear Away Debris


Leaves, dirt, and organic matter can trap moisture and create a breeding ground for mould and mildew. Before the first frost:

- Sweep away all debris.

- Remove fallen branches, potted plants, and outdoor furniture.

- Clear between deck boards with a narrow tool or putty knife to ensure proper drainage.


Thoroughly Wash Your Composite Deck


A deep clean in autumn removes buildup and reduces the risk of slippery surfaces or winter stains:

- Use a hose or pressure washer on a low setting.

- Apply a composite deck cleaner suitable for your materials.

- Gently scrub stubborn spots with a soft brush.

- Rinse thoroughly and let the deck dry completely before covering or storing items.


Inspect for Damage and Make Repairs


Before winter’s deep freeze sets in, check your deck for any signs of wear, such as:

- Loose or protruding boards

- Escaping fasteners or hardware

- Scuffs, chips, or cracks in the composite boards


Addressing minor issues now can prevent them from worsening over the winter. If you spot significant damage, Baird Construction’s expert team in Woodstock is ready to assist with repairs or maintenance.


Protect High-Traffic Areas


Snow and ice can cause unnecessary wear in high-traffic zones such as stairs or entry points. Consider:


- Placing outdoor rugs rated for composite decking (avoid rubber-backed mats, which can cause discoloration)

- Using furniture glides to avoid gouges or markings

- Storing heavy planters or décor elsewhere until spring


Safely Manage Snow and Ice


Ontario homeowners are no strangers to heavy snowfall, but using the right tools and techniques is crucial for protecting your composite deck:


- Use plastic or rubber-edged snow shovels to avoid scratching the surface.

- Shovel along the grain of the decking boards for best results.

- Avoid harsh ice-melting chemicals; opt for calcium chloride-based products, which are safe for composite materials.


Cover and Store Outdoor Furniture


Keeping your deck clear of bulky items over winter reduces the risk of moisture getting trapped underneath, which can lead to stains or microbial growth:


- Store patio furniture, umbrellas, and grills indoors if possible.

- If items must remain outside, cover them with breathable, waterproof covers.

- Make sure nothing is left touching the decking for long periods.
