Protecting outdoor living spaces from the impending cold is a common concern for homeowners. Maple Ridge has a 3.1-month cold season from November to February, with daily highs below 48°F. December is the city’s coldest month, averaging 33°F and 42°F.
Weather conditions like snow, ice, and rain can ruin furniture, patios, and appliances. As comfortable as these spaces are in summer, they need special insulation, sealing, and maintenance in winter.
This is the time of the year when you really need dependable deck installation companies to ensure the longevity of your space. But today, let’s first address moisture control during winter, how to choose suitable heaters and the best ways to store and cover furniture.
The Importance of Insulating and Sealing Spaces
All year round, outside areas are subject to environmental stresses. Winter conditions—such as freezing temperatures, high humidity, and snow accumulation—are particularly harsh. Inadequate sealing and insulation in these areas may lead to:
- Heat Loss. The loss of heat from cracks and gaps makes it hard to keep a comfortable temperature. This lowers comfort and increases heater load and energy use.
- Structural Damage. Moisture and freeze-thaw cycles can crack, warp, or rot wooden and composite decking. These conditions can weaken structures, causing safety hazards and costly repairs.
- Rust and Corrosion. Appliances, heaters, and metal furnishings can rust or corrode from snow, rain, and steam, affecting functionality and appearance.
- Mould and Mildew. Without moisture control, mould and mildew grow in furniture, cracks, and porous surfaces, posing health risks and damaging materials.
Sealing Gaps and Cracks in Decks, Patios, and Enclosures
The first defence against cold air infiltration is sealing. Particularly at the joints between the decking and the walls, you must ensure that no cold air or water can seep into your deck or patio.
Identifying Vulnerable Areas
- Between deck boards. Wood or composite decking boards may expand and contract, leaving small gaps. The gaps allow cold air and moisture to enter, worsening structural damage during freeze-thaw cycles.
- Railings and posts. Railings and support posts are common cold air entry points. Gaps between the posts and floor surface allow for drafts and moisture.
- Enclosures and pergolas. Pergolas and screened-in patios have gaps around doors, windows, and wood or metal beam seams. Thoroughly inspect these areas before sealing.
Sealing Solutions
Caulk and Weatherproof Sealants
Fill cracks and gaps around railings, posts, and deck-wall junctions with exterior-grade caulk or sealant. This deters moisture and heat loss. For larger decking board cracks, use a waterproof, flexible sealant or filler. Use products that can withstand extreme temperatures and UV exposure.
Foam Weatherstripping
Foam weatherstripping is inexpensive for entryways like sliding doors, windows, and hinged doors. It seals small gaps and prevents drafts. Adjustable door sweeps can block cold air if doors are misaligned.
Under-Deck Insulation
Insulating the underside of elevated decks with rigid or spray foam insulation traps heat and prevents freezing. This reduces heat transfer from below the new deck and prevents freezing.
Insulating and Protecting Outdoor Furniture
The accumulation of snow, dampness, and temperature swings can damage furniture. Think about insulating and storing it properly to keep it safe during winter.
Common Types of Furnishings and Their Risks
|
Wooden |
Especially susceptible to moisture absorption and freeze-thaw cycles. May leadto cracking, splitting, or warping. |
|
Despite their durability, teak, cedar, and treated wood need protection. |
|
|
Metal |
Long-term snow and moisture exposure rusts and corrodes metal. |
|
Although cast aluminum and stainless steel resist rust, iron and steel need special care. |
|
|
Plastic and Resin |
While more weatherproof, plastic may crack in extreme cold. |
|
Under winter stress, poorly made resin wicker may unravel or snap. |
Proper Storage Methods
Use Waterproof Covers
Buy high-quality, breathable, waterproof covers that fit your things snugly. The patio covers should be designed to repel rain and snow while allowing airflow to prevent condensation and mould growth beneath the fabric.
Elevate Furniture
Place them slightly above ground level using furniture risers or weatherproof pads to prevent them from sitting in snow or pooled water. This prevents moisture from wicking and damaging the material.
Indoor Storage
The best place to store them is a shed, garage, or covered patio if space allows. This indoor protection protects wood and metal furniture from extreme cold and moisture. Before storing, clean and dry all surfaces to prevent mould growth or rust during storage.
Applying Protective Coatings
Applying treatments or finishing touches to backyard furniture before winter arrives will add an extra layer of protection:
- Wood Sealants. Apply high-quality wood sealant or oil to wooden furniture. This reduces moisture absorption and warping/cracking. Winter sealants with UV protection can help wood retain its colour.
- Rust Inhibitors. Apply rust-inhibiting spray or paint to metal furniture. Sand rust spots and apply rust-resistant primer before covering your things for the season.
Selecting the Best Outdoor Heaters for Cold Weather Comfort
If you have an efficient heating system, you can use your custom deck or patio even when it is cold outside. Heater types vary in output, energy efficiency, and coverage.
Propane Patio Heaters
Propane heaters are popular due to their high heat output and portability. Freestanding propane heaters with reflectors distribute heat downward.
- Heat output. Provides 30,000 to 50,000 BTUs, ideal for open decks and patios.
- Efficiency. Open-air heat dissipation makes it less efficient for small or enclosed spaces.
- Safety considerations. Always keep propane heaters on stable, flat surfaces and away from combustible furniture covers and wooden railings. Store and replace propane tanks safely per manufacturer instructions.
Electric Infrared Heaters
Electric infrared heaters are popular for targeted heating. Instead of warming the air, they emit infrared rays that warm objects and people. Their efficiency is high in enclosed or semi-enclosed spaces.
- Heat output. Provides fewer BTUs than propane models but focus heat where needed.
- Installation and power requirements. A nearby power source powers wall- or ceiling-mounted electric heaters. Be mindful of the electrical load; outdoor circuits must be sufficient to handle the heater’s power draw.
- Safety considerations. Infrared heaters do not produce combustion gases, making them safer for enclosed spaces. However, make sure the electrical components are outdoor-rated.
Natural Gas Heaters
Natural gas heaters are more permanent and connect directly to a home’s gas line. They cost more to install but provide continuous heat without tank refills.
- Heat output. These can produce 20,000–50,000 BTUs or more depending on size and model.
- Efficiency. These efficient heaters provide consistent heat in open and enclosed spaces without running out of fuel.
- Installation requirements. Connecting the heater to the gas line requires professional installation. Outdoor gas appliances must follow local codes.
Managing Moisture Control During Winter
One of the most significant dangers to outdoor areas during the winter is moisture. It seeps into crevices, freezes, and then expands, ruining the property and furniture. Effectively addressing structural elements and furniture care is essential for moisture management.
Waterproofing Decks and Patios
A waterproof sealant is necessary to keep water from your patio. How to do it correctly is as follows:
- Choose the proper sealant. There are tinted and clear sealants. Whether you use wood or composite for your brand-new deck construction, you should use a product made for that material. Invest in a sealant that can withstand water and UV rays for the best protection.
- Proper application. Remove any mildew, dirt, or debris. The surface must be totally dry before the sealant can be applied. Evenly coat all crevices and joints using a paint roller or sprayer.
Installing Drainage Systems
When water collects even on a sturdy deck due to poor drainage, it can freeze and ruin the surface. Put in place drainage systems like these to avoid this:
French Drains
You can install a French drain to redirect water away from ground-level custom decks, protecting them from potential flooding and ruining.
Gutter Extensions
Always put downspouts and gutters at an angle that keeps the water running off your deck building.
Slope Adjustment
Verify that your space slopes to allow water to drain away from the house.

Frequently Asked Questions (FAQs)
Is it okay to use the same insulation I use indoors for outside areas?
Fibreglass and other indoor insulation materials work well for insulating a home but are not meant for outdoor use. Adequate insulation should resist water, ultraviolet light, and temperature swings. Outdoor insulation like spray or rigid foam is the best material for undersides and enclosed patio walls.
What are the best cold-resistant flooring options?
- Composite decking is less likely to warp or crack in freezing temperatures.
- Stable and freeze-thaw-resistant slate and granite tiles are also good choices.
- Outdoor-rated porcelain tiles and rubber pavers provide slip resistance and thermal insulation.
How can I reduce winter wind chill in my outdoor space?
A wind barrier can significantly reduce wind chill in your space. Install clear PVC curtains, outdoor-rated screens, or strategically placed walls or shrubs in your deck design to serve as windbreaks. These barriers allow light and visibility while blocking cold winds, keeping the space warmer and more comfortable.
