How Much Does It Cost to Build an Above-Ground Pool Deck?

There are many design options to consider when building an above-ground pool deck. Similarly, several variables can alter the costs associated with building a pool deck, including the type of materials used, size of the deck, local building codes requirements and the cost of labour if you hire a contractor.

The average cost of an above-ground pool deck ranges between $4,700 and $7,800. Costs vary depending on geographic region, time of year and whether you build it yourself or hire a professional.

How to Choose Pool Deck Materials

You have a couple of suitable options when selecting the best material for your pool deck. Pressure-treated wood is the least-expensive choice upfront, but pressure-treated wood can be more costly in the long run due to high maintenance requirements and regular repairs, unlike composite material which has fewer ongoing maintenance requirements.. For an above-ground pool deck, consider composite decking such as Trex® decking for long-lasting durability with minimal maintenance requirements. We recommend you look for above-ground deck materials that:

1. Resists Mould

Suffice it to say, your above-ground pool deck will come in contact with a lot of water, which is a breeding ground for mould. Opt for a composite material that is mould-resistant to reduce the care & cleaning required.

2. Resists Rotting, Warping, & Splintering

Wood has a tendency to rot, warp, and splinter over time. Trex® composite decking may have a higher up-front investment for the average cost of an above-ground pool deck but will save you time, money and peace of mind in the long run.

3. Match Your House

With more than 20 colours in its three decking collections, Trex® composite decking comes in a variety of browns, reds and greys that will complement and match your home's colour, whether brick, siding or masonry.

Best Materials for Above-Ground Pool Decks

When it comes to building an above-ground pool deck, there are some commonly used materials. But choosing which is the best pool deck material for your unique needs is crucial.

Trex® Composite Decking for Above-Ground Pool Decks

There are a number of reasons that composite decking is such a popular and smart choice for an above-ground pool deck. Trex® composite decking is a sustainably sourced material, made from 95% recycled plastic and reclaimed wood. It’s made with an earth-friendly manufacturing process which reclaims factory waste, and no harmful chemicals, such as VOCs, are used to make the boards.

Trex® decking has several advantages over the competition. It doesn't require annual painting, sealing, or staining. It resists rotting, warping, splinters and weather-related cracking, which is critical since your deck will be in the thick of all the splashing action in the pool. Trex® composite decking is also stain-, fade- and insect-resistant, which will keep your deck looking like new despite prolonged exposure to sun.

PVC Decking for Above-Ground Pool Decks

PVC decking is another popular choice for above-ground pool decks. Like composite, it’s resistant to rot, and mildew due to its all-synthetic composition that lacks absorbency. However, there are a few differences between PVC decking and composite. Because it’s non-absorbent, PVC decking can be slippery. This can pose a potential hazard when there’s a lot of splashing, playing, and running on an above-ground pool deck.

Another drawback of plastic decking is that some untreated PVC products can peel or fade over time, diminishing the attractiveness of your deck. Although PVC doesn’t require the regular maintenance of wood, it can splinter or crack under cold temperatures. This is something to be mindful of if you live in a colder climate and don’t want a disappointing surprise when you open your pool for the summer.

Wood Decking for Above-Ground Pool Decks

Wood has long been a go-to for building above-ground pool decks. Many builders and homeowners look to wood as a solid option. While different types of wood have different strengths, it’s a high-maintenance material that requires seasonal upkeep.

Wood doesn’t get as hot as PVC and composites  when in direct sunlight, however, while you won’t get a case of hot foot when walking barefoot on your deck, you may get a splinter since wood can warp and splinter over time. When comparing it to composite pool decking like Trex, wood is subject to moisture-related rot, fading, and staining from exposure to pool chemicals. This can make your above-ground pool deck look worn and aged before its time, unless you submit to a regular regimen of sealing and power washing. In addition to being vulnerable to the elements, wood is also prey to termites and insect infestation, unlike composites, which can compromise the structural integrity of your deck.

Pool Deck Maintenance Tips for a Trex® Composite Deck

With Trex® decking, long-term maintenance is a cinch compared to wood. All that’s needed is a simple, periodic soap-and-water cleaning or a gentle pressure wash (less than 3100 psi). This will keep your above-ground pool deck looking great year-round. Another maintenance tip for pool decks is do not leave spilt pool chemicals on the decking surface for long periods of time. While in most cases it would not harm the decking, it’s best to remove and clean these areas if this occurs.

When using a pressure washer, spray your above-ground pool deck with soap. Follow with a soft-bristle brush on each individual deck board. Then finish with a rinse on the pressure washer. Do not get the nozzle of the pressure washer closer than 8 inches away from the board for best results.
