In Quebec, the deck occupies an important place in the exterior design of houses, cottages, and garages. Once spring returns, it becomes the beating heart of the home. We enjoy meals there, entertain loved ones, and admire the sunsets. Yet, this extension of the home is too often neglected in terms of maintenance.
Constantly exposed to the vagaries of the Quebec climate—snow, ice, rain, humidity, UV rays—it requires regular care to remain beautiful, safe, and functional. Improper maintenance can lead to rapid deterioration of the material, loss of value, and even costly repairs.
At Plan Maison Québec, we know that the durability of a deck doesn't depend solely on quality materials and a well-thought-out design. Success also depends on rigorous maintenance, season after season. Here is a comprehensive guide that will help you understand how to maintain and protect your deck, from its design to winterization.
Why build a terrace: more than just a luxury
Building a deck isn't just adding a decorative element to your home or cottage; it's a true extension of your living space. It becomes an open-air space, a gathering place for relaxation and enjoyment, which not only increases your quality of life but also your property's value.
A well-designed deck allows you to fully enjoy the beautiful weather, cook outdoors, read in the sun, or share a meal with loved ones. In a region like Quebec, where summer is short but intense, every day spent outdoors counts. A well-designed deck prolongs this season of joy, especially when it's intelligently oriented, sheltered from the wind, or protected by an awning.
Plan Maison Québec supports homeowners in this process, offering personalized plans that blend harmoniously with the existing architecture while meeting everyday needs. Whether for a main home, a wooded cottage, or a converted garage with a rooftop terrace, we believe that every project deserves a unique and sustainable design.
Quebec's climate: a challenge for terraces
Quebec has one of the most demanding climates in North America. Decks there face a succession of extreme conditions: prolonged winter freezes, sudden thaws, soggy springs, hot summers accompanied by intense UV rays, not to mention autumn winds that carry dead leaves and moisture. A poorly protected deck can quickly show signs of deterioration: wood splitting, swelling, rot, discoloration, and structural cracks.
When Plan Maison Québec develops custom deck plans, we consider these variables from the outset. Sun orientation, type of wood or composite, rainwater drainage, board spacing, ventilation under the structure: everything is designed to reduce the effects of climate and simplify maintenance.
But even with intelligent design, no material is invincible without proper care. A deck in Quebec requires constant vigilance, especially if it's made of natural wood.
The Importance of a Deep Spring Cleaning
In the spring, once the snow has melted and the ground has dried out, it's time to give your deck a new lease on life. The first step is to visually inspect the entire structure.
Look for loose nails or screws, cracked or warped boards, black mold stains, or signs of rot in damp areas. These early signs are valuable indicators of the overall condition of your deck.
Cleaning is then done using mild soap, warm water, and a stiff-bristled brush. Each board must be thoroughly scrubbed, including the cracks and crevices, to remove dust, mold, algae, and winter residue. Some homeowners opt for a pressure washer, but using this tool requires great caution. Using too much pressure can damage the wood fibers, lift splinters, or remove previously applied finishing products.
If you used snow removal products or salt during the winter, these may have seeped into the wood and contributed to its deterioration. Spring cleaning helps restore surface balance and prepare the wood for a new protective treatment.
Protective treatment: sealing in beauty and durability
Once the surface is cleaned and completely dry (which can take 48 hours or more depending on conditions), the next step is to apply a protective product. This can be a clear sealer, a natural oil, a semi-transparent, or an opaque stain. The choice will depend on several factors: the wood species used, the desired style, the acceptable level of maintenance, and exposure to the elements.
A waterproof sealer effectively protects against water penetration, which is the number one enemy of wood in Quebec. A stain, on the other hand, provides an additional layer of protection against UV rays, which dull and gray the wood over time. For untreated wood decks such as cedar or pine, treatment every two years is strongly recommended. Oil-based products have the advantage of deeply nourishing the wood, but must be renewed more frequently than synthetic stains.
Plan Maison Québec recommends using products specifically designed for northern climates, ideally eco-friendly, to protect both your deck and the environment. Product quality, adherence to drying times, temperature at the time of application, and uniformity of work are all factors that will influence the effectiveness of the treatment.
Summer maintenance: prevention and vigilance
In summer, the key is prevention. It's no longer about major renovations, but rather a series of simple steps to take to keep your patio clean and healthy. The surface should be swept regularly to prevent the accumulation of sand, dust, or dry leaves. It's advisable to clean food or drink stains as soon as they appear to prevent them from setting in. A spill of red wine or cooking oil left too long can leave a permanent mark.
Also consider moving your outdoor furniture from time to time to avoid uneven marks caused by UV rays. Outdoor rugs should be removed when wet, as they trap moisture against the wood. Flower pots should be raised or placed on saucers to prevent waterlogging.
Special attention should also be paid to ancillary structures such as ramps, railings, and stairs, which are often exposed as much—if not more—than the decking. An unstable ramp or slippery staircase can pose a danger to users. These elements should also be inspected and maintained throughout the summer.
Preparing the terrace for winter: autumn as a key period
Fall is a critical season. Too often, homeowners wait for the first snowfall to put away furniture or cover their decks. However, precautions must be taken as soon as the leaves fall. Dead leaves retain moisture and promote the growth of fungi and mold. They must be picked up regularly.
Before the first frost, a final cleaning with soap and water is essential. Once the deck is completely dry, all furniture, rugs, umbrellas, and accessories should be put away or covered. It is also recommended to remove any objects that could damage the deck if they shift in the wind or snow. Proper winterization helps minimize potential damage caused by frost, standing water, and accumulated snow.
At Plan Maison Québec, we encourage our clients to plan any renovations or improvements to their decks as early as the fall. It's often easier to schedule the work during the winter so it can be completed quickly the following spring.
Protecting your terrace during winter: be vigilant even under the snow
Once winter has fully set in, it can be tempting to completely forget about your deck until the warmer weather returns. However, even when covered in snow, it continues to be exposed to the elements. It is therefore important to adopt certain best practices to avoid structural damage invisible to the naked eye.
First, avoid leaving excessive snow accumulation on the surface, especially if your deck is raised. Overloading can put unnecessary stress on the structure, especially if the wood is already weakened by moisture. Use a plastic shovel to partially remove the snow, always moving in the direction of the boards to avoid scratching them.
You should also avoid using salts or chemical de-icers, which can seep into the wood fibers, accelerating its deterioration. It's better to tolerate a little ice than to compromise the durability of the structure. It is also recommended to periodically check whether water infiltration is accumulating near the base or anchor points of the terrace.
A little vigilance in winter often helps avoid costly surprises in the spring. Plan Maison Québec recommends incorporating this winter routine into your maintenance routine, especially if your deck is an important part of your outdoor space.
The role of material choice in ease of maintenance
Not all materials are created equal when it comes to climate change. Natural wood, while very popular for its character and warmth, requires regular maintenance. Eastern white cedar, widely used in Quebec, has good natural resistance but must nevertheless be treated.
Pressure-treated wood is more durable but must also be protected to maintain its appearance. Exotic woods, such as ipe, are very durable but expensive and require specific maintenance.
Composite decking is an attractive alternative. Made of wood fibers and plastic resins, they are more resistant to moisture, insects, and UV rays. They do not require annual treatment, but occasional cleaning is still necessary to maintain their appearance.
Concrete, on the other hand, offers great durability but can crack due to frost if poorly drained. It must be sealed periodically to prevent water penetration. Pavers, on the other hand, require regular weeding between joints and careful attention to sagging.
Plan Maison Québec helps you choose the materials best suited to your situation, taking into account your aesthetic preferences, your budget, and the level of maintenance you are willing to provide.
When to call a professional for maintenance
If you're comfortable with DIY, many maintenance steps can be completed yourself. However, some situations require professional intervention: repairing sagging structures, replacing rotten boards, re-sealing joints, and assessing the supporting structure. Hiring an expert helps ensure the safety, compliance, and longevity of your deck.
When you choose a personalized plan with Plan Maison Québec, you also have access to a network of qualified partners who can assist you with the maintenance and renovation of your deck, according to your needs and the seasons.
