5 Best Composite Decking Shops in Calgary for Alberta Winters
Scraping and staining a rotting wood patio every spring gets old fast, especially after harsh chinooks warp half the boards. I spent two weekends sanding splinters off my old steps before I gave up on timber for good.
Low-maintenance composite saves your weekends, provided the boards can handle Alberta winters, so I compared composite decking shops in Calgary on stock, warranties and pickup terms.
Here are the best options and who each one suits best.
How much does composite decking cost in Calgary?
Composite decking in Calgary costs from $8 to $25+ CAD per square foot for materials alone, whether you’re building a do-it-yourself (DIY) backyard deck or upgrading a rental property. Hiring deck builders adds labour to your final bill.
| Option | Typical price |
| Budget or entry-level boards (e.g., basic lines from MoistureShield) | $8–$12 CAD per sq. ft. |
| Mid-range boards (e.g., Trex Select, Fiberon) | $12–$20 CAD per sq. ft. |
| Premium or capped polymer boards (e.g., Trex Transcend, TimberTech / Azek) | $20–$25+ CAD per sq. ft. |
1. Lumber King
Website: https://lumberking.co/
Address: 4544 8A St NE
Contact: (403) 277-2080
Hours: Monday–Friday: 8:00 AM–4:00 PM
Estimating board counts and hidden screws for a weekend do-it-yourself build is easy to get wrong. Lumber King helps with material takeoffs and project consultations, so you don’t overbuy.
Second-generation owner Dan runs the shop, which is accredited by the Better Business Bureau (BBB).
When I called their yard to ask about mixing pressure-treated framing with composite tops, the staff walked me through the fastener counts right away.
They carry Trex, Voyage and Azek boards. They also stock the hidden fasteners, railings, balusters and privacy screens you need to finish the job.
Having all those parts in one order saves home builders and weekend warriors from hunting for matching hardware across town.
However, their delivery trucks cover Calgary and surrounding areas, so drop-off slots can be limited. Homeowners also compete with landscapers and contractors for those trucks, so book early or haul the load yourself.
Can’t recommend the team at lumberkings enough.
Spencer at lumber kings is a fantastic member of the team, he helped us with materials & delivery for our deck project during the off season. Spencer went over and above. Can’t recommend the team at lumberkings enough.

If there was such a thing as a 6 star rating, this company would earn such a review.
All of the rave reviews seen here are 100% true! Danny and his crew are wonderful to work with, the materials are of excellent quality, and delivery is effortless! What more could anyone ask for from a local company?

2. TimberTown Building Centre Ltd, Calgary NE Store
Website: https://timbertown.ca/
Address: 4215 12 St NE
Contact: (403) 291-1317
Hours: Monday–Friday: 7:00 AM–5:00 PM; Saturday: 8:00 AM–4:00 PM; Sunday: Closed
Shopping for outdoor boards without knowing the price per plank wastes your afternoon. TimberTown Building Centre lists characteristics and prices on their website.
Their wide selection serves homeowners, renovators and contractors who want to compare costs at home before visiting the showroom to talk with an expert.
Their main lines are Trex and TimberTech composite boards, both made in the USA mostly from recycled materials and backed by 25- to 50-year warranties.
Those boards keep a consistent look with fewer flaws across patios, pool decks and waterfronts, which suits eco-conscious buyers and real estate investors alike.
Saturday hours also mean DIYers don’t have to take time off work to view textures in person.
That said, the shop closes on Sundays, so you lose half the weekend if you run short on supplies mid-build.
They also run several Calgary locations, so double-check that you’re heading to the 12 Street NE store.
He pretty much sold us on buying from Timbertown
I recently had the pleasure of purchasing a composite deck package from Timbertown. My sales rep was Feda (goes by Fidel) and he was awesome. My wife and I didn’t know anything about the product. Fidel not only walked us through the different brands, colours and differences between each line, but gave us a comprehensive education on how it goes together, tips for installation and more. Having shopped around for our project, he pretty much sold us on buying from Timbertown, and he offered my kids a lollipop and had them involved as well.

The gentleman at the order desk that we spoke to was very helpful.
We recently moved into a new home and needed to build a deck. We supplied TimberTown with a fairly detailed drawing of what we wanted to build. The gentleman at the order desk that we spoke to was very helpful. We took small samples home with us to determine color. We had a quote back in less than 2 days. We placed the order with the colors we had chosen and asked for a specific day for delivery. Once home, we were able to change the delivery one day earlier.

3. Eco Deck Ltd
Website: https://ecodeckcanada.com/calgary-composite-decking
Address: 6520 68 St SE
Contact: (403) 431-2065
Hours: Monday–Sunday: 10:00 AM–3:00 PM (office hours; pickup by appointment only)
Eco-conscious homeowners who want to check board colours in their own backyard light will appreciate how Eco Deck works.
They operate from a private distribution yard in southeast Calgary and ship free sample boxes to homeowners’ doors.
They supply Dual 360° co-extruded composite boards, where the inner core and outer shell are fused together for stability.
And the lightweight honeycomb core blends recycled wood fibres with high-density polyethene (HDPE) using non-toxic glue. That recycled core suits eco-conscious buyers and is much easier to carry during a DIY install.
The outer shell protects the core, since a full 360-degree Surlyn layer blocks moisture, stains and ultraviolet (UV) fading. A 25-year limited warranty backs the boards.
On top of that, contractors can book pickups any day of the week, since the office is open seven days.
That said, there’s no public showroom for browsing, and every yard pickup needs a scheduled appointment between 10:00 AM and 3:00 PM.
I recently bought composite decking from Eco Deck in Calgary and was really happy with the experience.
I recently bought composite decking from Eco Deck in Calgary and was really happy with the experience. I went with their Prestige clearance boards and the price for the quality was hard to beat compared to other places I looked. The boards look great and feel solid, and everything was exactly as expected. Communication was quick and easy the whole way through. I also looked at their newer Dual 360 decking, which seems like a really solid upgrade, but for what I needed the Prestige made more sense and still turned out great.

I would definitely recommend
I had trouble narrowing down where to purchase composite decking from and decided to reach out to EcoDeck on a whim… and it’s been a great decision so far. The free samples were really helpful in our decision to get the Dual 360 boards.
Above all, John was great to interact with even while he was on vacation – detailed, responsive, and super friendly! I would definitely recommend

4. Mountain View Building Materials
Website: https://mountainviewbm.ca/
Address: 125 Commercial Court
Contact: (403) 242-0404
Hours: Monday–Friday: 7:00 AM–4:30 PM; Saturday–Sunday: Closed
Homeowners who want sturdy boards without managing the installation themselves get extra help at Mountain View Building Materials. Their team sells local lumber, house siding and composite decking.
They also help with design and connect you with a trusted contractor.
Whether your project is a backyard patio or a commercial space like a restaurant or hotel, they can help plan it. You can also coordinate the deck with retaining wall pros before the planks go down.
They stock Fiberon, Eva-Last, TimberTech and Deckorators, with a focus on sustainably sourced materials that survive Alberta’s wild weather swings.
A contractor friend of mine sourced TimberTech from their yard for a condo patio last summer and liked how well their stock handled the winter freeze.
Just keep in mind that the yard closes all weekend and at 4:30 PM on weekdays, which is tough if you work regular office hours.
Residential buyers also compete with commercial accounts for scheduling slots.
Mountain View consistently lives up to my expectations and more often than not, exceeds them.
I have used Mountain View Building Materials for supplying decking products for my small business and other materials for my personal projects for the past 3 or 4 years. I am someone who values honesty, open communication and OTP in dealings with businesses. Mountain View consistently lives up to my expectations and more often than not, exceeds them.

5. The Cedar Shop Building Materials
Website: https://shop.cedarshop.com/
Address: 285 Manitou Rd SE
Contact: (403) 243-5720
Hours: Monday–Friday: 7:00 AM–5:00 PM; Saturday: 8:00 AM–4:30 PM; Sunday: Closed
Planning a full backyard overhaul is easier when you can see full-sized displays indoors.
The Cedar Shop Building Materials, a family-owned supplier serving Calgary builders since 1978, runs a 15,000-square-foot showroom inside a 53,000-square-foot facility. It’s the largest dedicated cedar showroom in Canada.
For decking, they sell composite and polyvinyl chloride (PVC) boards from Deckorators, Eva-Last, Fiberon and TimberTech/Azek, as well as wood.
You can also grab concrete mix, privacy screens, lattice and Harvia or Homecraft sauna heaters in the same trip, which suits real estate investors upgrading a whole yard.
Their trained delivery specialists then bring everything to the home or job site, so boards arrive undamaged.
On the flip side, they don’t keep every composite line in stock on site. If your chosen board isn’t in the yard, you’ll need to call ahead and wait for delivery.
If you find something that you can use, you can’t beat the savings.
We were looking for a deal on composite decking. We took the time to look through their “unloved” area in their yard and found a perfect amount for our new, small deck. If you’re prepared to do a little extra work sorting through these returns, if you find something that you can use, you can’t beat the savings.
