What Our Clients Say
Rated 4.8 stars from verified Google reviews47+ verified Google reviews
“Wes and team came out in January and gave a quote, they then were able to come mid April and complete it. Communication and expectation setting was great, materials used are awesome and they cleaned up the site nicely too. Would highly recommend to anyone.”
“Very happy with Wes and his team! There was one minor miscommunication, which we realized as they were building our deck that the boards were the wrong color. They resolved this quickly without hesitation and still had our deck built within 2 days. Highly recommend and would definitely use them again!”
Composite Deck FAQs
Get answers to the most common questions about composite deck construction in Calgary.
How much does a composite deck cost in Calgary?
Most composite deck projects in Calgary range from $15,000 to $65,000+ depending on size, materials, and features. The wide range comes down to deck size, complexity, railing choice, and whether permits are required. We provide a written estimate before we lift a board — not a ballpark number that changes once work begins.
Do I need a permit to build a deck in Calgary?
Most elevated decks in Calgary require a development permit and/or building permit. Decks over 0.6m (2 feet) above grade typically need permits. We handle all permit applications, engineered drawings, and inspection coordination as part of our service.
How long does composite decking last in Calgary?
Modern composite decking from TimberTech and AZEK is engineered to last 25–50 years with minimal maintenance. The capped polymer technology resists fading, scratching, staining, and moisture damage — even through Calgary's extreme freeze-thaw cycles. Most products carry 25–30 year manufacturer warranties.
What brands do you use for composite decking?
We are a TimberTech Platinum Contractor and AZEK University certified. We primarily install TimberTech and AZEK products because they offer the best performance, warranties, and aesthetics. We can also source other premium composite brands based on your preferences.
Do you require a deposit to start a composite deck build?
No. A composite deck is a significant investment and we think it is unreasonable to ask for your money before you have seen the work. You pay nothing until your deck is built, inspected, and you are satisfied with the result.
