Save Money and Make Informed Decisions With This Informative Guide to Composite Decking Prices

Since the cost of wood has nearly doubled, composite decking that requires little upkeep looks better than it ever has. When conducting research on the available options and comparing pricing, it is important to keep in mind that many manufacturers provide several product lines at different price points, which can be referred to as “good, better, and best.” In addition, the vast majority of composite decking is sold by the linear foot; however, given that the width of decking might differ from one product to another, comparing pricing based on square footage can provide you with more accurate findings. The majority of bids submitted by contractors are calculated based on square footage.

Your search for composite decking should be limited to providers who can provide you with an up-to-date engineering report. Without one, many building authorities will not provide a permission to construct a building. (The reports provide a synopsis of the findings of the tests conducted on the manufacturer’s products.) The availability in the surrounding area is also a significant consideration. When looking for composite decking, it is advisable to find a local distributor, lumberyard, or other retail business that carries it in stock. Because of this, exchanges and subsequent purchases will be more convenient.

When it comes to hosting gatherings outside, nothing beats the classic appeal of a spacious and attractive deck. Nothing gets greater use than a nice deck on a sunny day, from the braais to the talk that takes place there. In addition, since the cost of natural wood decking and composite decking is getting closer to being comparable, it is essential to be familiar with the benefits that composite decks have over natural wood decks.

So, how much does it cost to buy composite decking in Gauteng, South Africa?

Composite decking material alone, the cost of a composite deck can range anywhere from R500 to R1200 per square meter, while the total cost of an installed composite deck can be anywhere from R300 to R550 per square meter (joists, posts, and beams). Installed prices range from R320 to R700 per square meter for natural wood decks. Prices will tend to be higher for more desirable types of wood, such as cedar, redwood, and IPE, which is a type of tropical hardwood.

Considerations in Deck Pricing

Decks often also come equipped with railings, stairs, and fascia. As a consequence of this, the cost of the decking by itself does not accurately reflect the total cost of constructing a deck. Building location, deck size, and design decisions will all play significant roles in the process.

Other considerations to take into account:

  • Warranty. Wood decking typically does not include a warranty, but the main producers of composite decking such as ourself here at Ecotech Timbers offer a warranty period of at least 20 years.
  • Maintenance. The majority of wood decks need a thorough cleaning and refinishing every few years, which can be both time-consuming and expensive. Using a brush and a light cleaning solution, you can easily clean a composite deck.

When compared to the cost of wood decking, does composite decking offer value for the money?

According to these estimates, the cost of a composite deck can range anywhere from R13,000 to R18,000, while the cost of a wood deck can range anywhere from $10,000 to $17,000. Although this may seem like a significant difference at first, the cost of composite decks is lower in the long run than that of real wood decks since they require less maintenance, endure longer, and continue to look good for longer. In point of fact, thanks to its superior durability, a composite deck made of Trex can easily make up for its higher initial cost over the course of its lifetime.

When compared to decks made of natural wood, which, even with regular maintenance, may only endure for 15 years, composite decks may be maintained to last for 25 to 30 years or even longer. Because they contain a combination of organic and synthetic fibres and are encased in a protective synthetic shell, composite deck boards are resistant to mould, warping, and staining. This is made possible by the protective synthetic shell. In addition to that, they do not fade or become scratched.

The Ever-Increasing Cost of Wood
Beginning in the year 2020, there was a 275% increase in the price of wood. Even if prices are lower now than they were in the past, the cost of wood is still about twice what it was. In the meantime, the price of composite decking has not altered by a significant amount. Because of this, composite decks are quite competitive even when compared to pressure-treated pine, which is the option of wood that has the lowest cost. In point of fact, the price difference between composite decking and decking made of wood has never been so small.

Avoid Wasting Time and Money Comparing the Costs of Composite Decking Brands
It is crucial to do price comparisons in order to guarantee that you are getting the greatest product for your money. There are many brands of composite decking, and each brand offers a variety of products that may be purchased at varying price ranges. You can find out how pricing relates to appearance and performance by checking out the websites of the relevant manufacturers and going to your neighbourhood distributor or retailer.

You should also be able to pick up samples of composite decking materials from your local lumberyard or dealer, and you can order these samples online. In most situations, this should also be possible. It is a good idea to conduct some practical tests at home to determine how readily the surface can be scratched with a key or discoloured with some oil or ketchup. You can accomplish this by following the instructions in the previous sentence.

Some materials have a greater propensity to fade than others. If your deck will be in an area that receives very little shade and a lot of direct sunlight, you should search for a finished project or an outdoor exhibit that has been out in the weather for a few years. Check the deck boards to assess how well they have held up against fading by comparing them to fresh ones.

Check out our detailed pricing comparison table for composite decking, which features the most popular brands on the market today and includes an estimate of the price of Trex decking on average. Trex’s low-maintenance decks are around two to five times more expensive than wood, depending on the performance tier, which can range from low-cost to premium. However, they are built to last for decades and have a reduced total cost of ownership over the course of their lifetimes.

The Price of Composite Material to Replace Wooden Deck Boards

It is possible for the cost to range between $15 and $25 per square foot to replace wooden deck boards with composite material. This variation in costs may be impacted by a variety of factors, including the cost of labour, the size of the deck, the intricacy of the deck’s shape or patterns to lay the decking, and the cost of composite materials. The price of new composite decking can range anywhere from $8 to $22 per square foot, depending on whether or not you want to install it yourself.

Because wood decking requires regular maintenance, many homeowners eventually make the decision to remove their hardwood deck boards and replace them with composite decking, which requires significantly less upkeep. It is possible to simply replace wooden decking with composite decking; however, if the structure and framing components of your deck were originally built of wood, you will want to check that the deck is in good structural condition and that the joists have not decayed. In most cases, replacing the boards alone is not something that is suggested. Think about installing composite framework in place of the wood structure that supports your deck.


Tip #1 – Firstly, lets look at what NOT to do when cleaning composite decking

No Bleach

Don’t use bleach or other harsh chemicals when cleaning composite decking. These can cause discoloration and damage to your decking’s finish, as well as pollute the ground around your house or pool area.

No Steel Wool

While cleaning composite decking don’t use steel wool or other abrasive materials on composite decking surfaces—they’ll scratch the finish and dull its appearance over time!

No Boiling Water

Don’t use water that’s too hot or too cold when cleaning composite decking. Water that’s too cold won’t be able to remove dirt from the surface of the decking; water that’s too hot may cause damage to the wood fibers and dull the finish over time. Use warm water instead of cold when cleaning your decking If you feel you need to use hotter water then, hot tap water from your geyser will do.(around 70 degrees Fahrenheit max).

Tip #2 – How often should you clean your composite decking?

We recommend that you wash your composite decking at least every six months, ideally on a warm, sunny day. We have more information about general maintenance on your composite decking.

If your deck is in full sunlight, we suggest you wash small areas at a time; this will prevent the soapy water from drying before you can wash it off

Tip #3 – Deck preparation for cleaning

To protect them from cleaning products, first cover any plants, grass, garden décor, or other anything that are close to or under your deck. Remember that plants or grass maintained under cover for an extended period of time risk dying.

Take out all furniture, including tables, chairs, barbecues, rugs, and potted plants. Clear the surface, including the corners, of any debris such as branches, leaves, and any other objects. To remove dirt and leaves from the cracks, use a wide putty knife. The deck should then be hosed off to remove any loose dirt or debris.

Tip #4 – Clean the Deck with Water, Liquid Detergent and a Nylon Bristle Brush

The majority of surface stains and layers of dirt and grime that collect on a composite deck can usually be removed with just a thorough scrubbing with soapy water and with a scrubbing brush.

Pour 5ltr of warm water  into a bucket with a ¼ cup of liquid dish detergent, such as Sunlight Liquid, which is biodegradable, safe for both people and animals into a bucket. While being gentle enough to neither harm the environment or your skin, it is also powerful enough to remove debris from the rough grain of composite decking.

For stubborn stains pour a light dishwashing liquid directly onto the composite decking and scrub with the scrubbing brush.

Spray the deck off with a hose to remove all soapy water. Allow to dry in the sun.

Tip #5 -How to clean the grooves in the decking

Scrubbing the boards of your deck is only one part of the cleaning process; you also need to be familiar with the proper technique for cleaning the grooves. Utilizing the bristles on your broom or brush to sweep any debris out of the crevices is the most effective method for accomplishing this task.

Pro tip

Our composite decking has a coating which will help keep many stains to just on the surface, having said that it is always good practise to wipe up spills of any kind as soon as possible. It is more likely that they will seep into the decking and become more difficult to remove the longer they sit.

Tip #6 – Pressure Washing

Can you use a pressure washer to clean your composite decking, “Yes, you can, but use caution.”

It is not advisable to make use of high pressure washing systems to clean your composite deck as the pressure from the water can strip the wood grain, leaving it looking dull and splotchy, and it can also cause damage to your decking and void your warranty.

Cleaning composite decking with a high water pressure can harm your decking if not used appropriately.

While cleaning composite decking can typically be done without a pressure washer,  “warm soapy water, a deck brush, and some good ol’ elbow grease usually work the trick and keep your deck from potentially becoming damaged.”

A deck can be revitalised and a thin coating of grime removed by giving the surface a brief spray with the pressure washer fan tip. The fan tip reduces the nozzle’s pressure and reduces the likelihood of damage.

Tip #7 – Important to note: when pressure washing

In general, it is advisable staying below 1,500 psi (pounds per square inch). For the same reasons, keep the nozzle at least six inches away from the deck boards. Make sure you move with the grain of the board by making broad, sweeping motions.

Fill the pressure washer soap dispenser with dishwashing liquid or a solution made especially for pressure washers for decks with thick layers of dirt and difficult stains. For optimal results, read the manufacturer’s instructions. Use a hard brush to scrub away any tough stains, then work the cleaner into the corners.

Using the widest pressure washer nozzle (fan nozzle), clean the deck with plain water. Use the nozzle to make broad, sweeping strokes about two feet above the deck’s surface.

Tip #8 -How to Remove Mildew when cleaning composite decking

Mildew is a common problem on composite decking, especially in humid areas. If you’ve got a mildew problem on your composite decking, don’t worry! It’s not permanent—you just need to take the right steps to remove it.

What kind of mildew?

The first step is to figure out what kind of mildew you’re dealing with. If it’s black mold (Stachybotrys chartarum) which is often referred to as “toxic”, then you should call an expert who can help you get rid of it safely without exposing yourself or others in your home or yard.

However, if the mildew is greenish or white, then there are some things you can try at home before calling in an expert.

Removing the mildew

Unfortunately, simply washing off mildew won’t remove it—you’ll need to scrub the surface with a stiff-bristled brush to get rid of stubborn stains.

Here’s how: Use an enzyme cleaner such as Enviro Enzyme D’our from Blendwell Chemicals. Enviro Enzyme d’Odor contains microorganisms which are a very specific set of helpful microbes that are capable of decomposing organic material such a mildew and mould. The bacteria and enzymes that are produced during the digestion of the mildew are self-limiting and completely biodegrade.


Dilute 10:1 ratio, 10 liters water to one litre Enviro Enzyme D’our, apply to the affected area, then leave over night for the microbs to do their work. Wash off with a mild detergent.

Tip #9 – How to Remove Rust Stains from Composite Decking

Rust stains are often caused by the oxidation of iron or steel, which can occur when water comes into contact with the metal. If you have composite decking that has been discolored by rust, don’t worry! It can be fixed with a little bit of elbow grease and some natural cleaners.

1. Use vinegar

Vinegar is one of the most popular home remedies for removing rust stains. It can be used either as a spray or a soak. For best results, use white vinegar and make sure to rinse it off thoroughly once you’re done cleaning.

2. Use baking soda

Baking soda is another simple, inexpensive option that works well to remove rust stains from composite decking. Mix 2 tablespoons of baking soda with 1 cup of water, then scrub the stain with a brush or sponge until it disappears. You can also sprinkle baking soda directly onto the stain and let it sit overnight before rinsing it off in the morning and then cleaning up any leftover residue with soap and water.

3. Use lemon juice

Lemon juice is a natural alternative to vinegar that works just as well at removing rust stains from composite decking! Just mix equal parts lemon juice and water, then apply it directly onto the stain with an old toothbrush or sponge before letting it sit for 15 minutes (or more if needed). Afterward, wipe

Tip #10 -Removing Snow and Ice from Composite Decking

Even if you won’t be using your deck frequently throughout the winter, you might still want to clean the backyard access paths and make your deck a safe place to walk.

Make sure to use products and techniques that won’t harm the deck surface while clearing snow and ice off your composite deck.

Let’s look at the safest methods for using ice melt or shovelling your deck.

Using a shovel with a plastic or rubber edge to prevent damage, you can remove snow off composite decking without harming the deck. Don’t use something which may nick, cut, and hurt your decking in any way.

If there is any remaining ice or snow after using a scraper, spray it with warm water until all of it melts away.

Then use a soft bristled brush to clean out any remaining residue from the wood fibers of your decking.

You might not even need a shovel to clear your deck during mild snowfalls. You may easily remove any snow that is less than 1-2 inches deep using a broom.

Our composite products are made to withstand the elements and provide a long-lasting, stunning deck.
