Cost to build or renovate a deck in 2024

There’s nothing more enjoyable than relaxing on a deck, balcony or patio, with nothing else to do but enjoy the beautiful weather Or, why not set it up to work from home there. This outdoor space deserves a refresh from time to time. However, it can sometimes be challenging to choose the right material for a deck or balcony renovation. Various options are available, each with its pros and cons. To make your task easier, here’s a comparative table of materials with their respective prices for deck annd balcony construction.

The table below shows the average current prices per type of material. Of course, this can vary depending on the quality of the chosen materials, level of installation difficulty and several other factors.

*Please note that these prices are indicative. Several factors can influence the total cost of renovations, such as the type of work to be done, necessary labour, materials used, safety measures, demolition or displacement costs of structural elements, and unforeseen circumstances.

Factors influencing the cost of a deck

Demolition costs are among the main factors that can increase the bill. If an old deck needs to be dismantled, this can greatly increase the total cost of the project. The transportation cost of materials and equipment for a deck or balcony construction can also have a significant impact.

Quebec’s harsh winters also affect the cost. Deck structures must be designed to withstand extreme cold conditions, which may require more expensive materials or particular construction techniques.

Finally, the type of materials used can affect the total. Wooden floors may be cheaper but they require regular maintenance and don’t last as long as those made of aluminum, for example. The latter are more durable, require less maintenance but are more expensive.

Fibreglass deck

Recently popular, fibreglass is a very interesting material for deck construction. Indeed, it’s known for its lightness and durability. Fibreglass resists frost, fire, corrosion and sunlight without any problem, in addition to being waterproof. So, you can create storage spaces under your deck without fearing that your belongings will be damaged. This material does not tarnish over time and is easy to maintain. Just clean it from time to time with water and dish soap and you’re done! Finally, different colours are available and there’s even a wood imitation. 

On the downside, fibreglass is not very slip-resistant. You need to be careful not to trip or fall on rainy days and in the winter as the surface can get slippery. In summer, heat tends to be attracted to this kind of material – it’s possible that your deck or balcony will get super hot. Light colours are therefore a better idea. The cost of fibeglass is quite reasonable: $55/sq ft without the structure (covering an existing deck only) and $65/sq ft with the structure. The average lifespan of a fibreglass deck exceeds 20 years.

Wooden deck (treated wood, cedar, and roasted wood)

Very popular in Quebec, wood is an interesting choice: it’s ecological and economical. Its lifespan varies from 10 to 50 years depending on the species chosen and good maintenance can add a few springs. There are a multitude of types of wood and each has its advantages and disadvantages. A wooden deck lasts on average between 10 and 25 years.

Treated wood: The most common type of wood because of its affordable price. It must be treated every three years, which results in significant maintenance costs. It costs approximately $80/sq ft with the structure and installation.

Cedar: This wood is appreciated for its very natural appearance and its beautiful color. Treatment is necessary for it to retain its hue and not brown under the effect of bad weather. It costs approximately $100/sq ft with installation.

Roasted wood: Baked in the oven, this ecological wood contains no chemical agent. Its resistance to time is however limited and its cost is quite high, between $75 and $85/sq ft with installation.
