Budgeting for Composite Decking

Budgeting is a financial decision. The initial cost of composite decking is typically higher than materials such as pressure-treated wood. When making your budget, don’t forget to include the deck boards, the necessary installation tools, and the railing systems. Products with unique textures or colours, or high-end names, cost more. Before you set your budget, you should always ask providers for a full price list.

The cost-benefit of composite wood decking comes from how much it will be worth in the long run. Traditional wood decks need to be cleaned, sanded, sealed, or painted every year, which takes time and costs money. Good composite decking doesn’t need much care other than being washed with soapy water every once in a while.

So, when making a budget, you should think of composite deck materials as an investment that will last for a long time. Over the decades, it can save a lot of money, time, and effort on repairs.

Select Based on Usage Scenarios

What are the deck’s surroundings, and how often does it get used? This directly affects how well the composite decking needs to work. If your deck is where most of your family’s outdoor activities happen, choose boards that are stronger. For instance, choose solid composite wood for decks that are often used for parties or where kids play and run. Compared to hollow composite decking, it is stronger and lasts longer.

If your deck is near a pool or in a wet, rainy area, it’s very important that it doesn’t slip or grow mould. Make sure to choose items with rough surfaces that won’t slip. To keep water from building up and mould from growing, make sure the decking is very resistant to wetness.

Which Type of Composite Decking Should I Choose?

How well composite decking lasts over time varies depending on the materials used, how it’s built, and how it was made. Here are some of the ways that different types of composite decking work differently. Make your choice based on your needs and funds.

Capped vs. Uncapped Composite Decking

Capped composite decking has an extra layer of protection on top of its surface. Co-extrusion technology is used in this type to cover the board in a hard polymer layer. It successfully stops water from getting into the core by resisting moisture penetration. This stops the swelling, buckling, and mould growth that happen when water gets into the wood.

Capped composite decking is also much more resistant to UV light, which means it won’t fade as quickly when exposed to sunshine. Its smooth, thick surface also doesn’t let stains through, which makes cleaning very easy.

Uncapped composite decking, on the other hand, has a surface that is porous and doesn’t have a protective cover. Although it might be cheaper, it doesn’t cover as well as capped composite decking overall. However, even composite decking that doesn’t have a cap still works much better than traditional wood decking.

Solid Composite Decking vs. Hollow Composite Decking

For the best load-bearing performance, solid composite decking is the most stiff and resistant to impact. The solid feel underfoot comes from the fact that it doesn’t bend or sag. This makes it perfect for places with a lot of foot traffic or where big furniture needs to go. One of its flaws is that it is the largest, which makes it harder to move and install. In addition, solid composite decks usually have the most expensive price tag.

Composite decking that is hollow is the lightest and least expensive. It is also easier to handle and place because it is lighter. However, its building strength is not as high. If homeowners choose this option, they need to carefully check to see if it meets the load-bearing requirements.

Grooved-Edge vs. Square-Edge Composite Decking

The primary difference between tongue-and-groove and square-edge composite decking lies in installation methods. Tongue-and-groove boards typically use a hidden fastening system. This fastening method simplifies installation and creates a seamless, aesthetically pleasing appearance.

Conversely, square-edge composite decking is usually installed using deck screws. A drawback of this installation method is that screws may be visible. Ultimately, choosing between square-edge or tongue-and-groove boards depends on your preferred installation approach.

Understand Warranty Terms

The warranty period directly reflects the manufacturer’s confidence in their product. It indicates the product’s expected lifespan. Premium brands like EVODEK typically offer warranties lasting 25 years. When purchasing composite decking, carefully review warranty coverage terms. Ensure the following aspects are covered:

  • Fading: Guarantees color stability for a specified number of years.
  • Mold Resistance: Guarantees the material’s ability to resist mold growth.
  • Structural Integrity: Ensures no defects such as cracking, delamination, or breaking.
  • Material Defects: Covers any inherent material issues that may arise during use.

Keep in mind that warranties usually have strict rules about how to use something. Problems that happen because of bad cleaning, accidents, or natural events might not be covered. Before you buy, make sure you fully understand these terms.

Selecting the Right Style and Appearance

Your deck should not only be sturdy and durable but also complement your home and personal taste. The following aspects all influence the deck’s overall visual appeal.

Color and Style

Composite deck boards come in a lot of different colours and styles. Pick a colour that goes well with the outside walls of your house, the frames of your doors and windows, and the plants and trees around your home. Do not forget about the weather. Darker colours tend to soak up more heat, which could make them too hot to wear in direct sunlight. Lighter shades take in less heat and hide dust better.

Texture

High-quality composite deck materials usually have wood grain textures that look a lot like real wood. Some items even copy the colour changes and knots found in real wood. When you buy something, ask for samples so you can see how it looks in both natural and artificial light.

Fastening Methods

Installation techniques also determine the final visual appearance of your deck surface. Top-fastening is simpler and more cost-effective. However, screw heads remain exposed. While color-matched caps can conceal them, traces may still be visible. Hidden fastening systems achieve a completely nail-hole-free, clean surface. This method allows for faster installation and delivers an exceptionally elegant appearance.

Consider Installation and Maintenance Requirements

To make sure it works, composite wood decking needs to be installed correctly. Professional installation teams know the rules and specs for installation. So they can make sure the process meets standards. This is very important to make sure that your deck is safe for a long time. If your job is complicated or you don’t know how to do it yourself, it’s best to hire professionals.

Additionally, high-quality composite decking requires virtually no maintenance. Occasional cleaning is all that’s needed. Use mild soapy water to scrub during cleaning. Unlike wood decking, it requires no periodic sanding, staining, or painting. This saves you significant time and ongoing expenses.

Other Considerations

In addition to the points above, carefully consider these details to make sure the result is perfect.

  • Material Batch Consistency: Composite wood decking is produced in batches. To guarantee color uniformity, order all materials for your entire project at once.
  • Local Building Codes: Talk to your local building authority before you buy and install. Learn the rules about things like deck height, fence height and spacing, stair requirements, and more. Your design must comply with these codes.
  • Accessory Compatibility: Make sure that any decorations you choose are the exact same colour and style as the decking boards. When you can, choose items from the same brand.

Conclusion

Choosing composite decking materials is a comprehensive decision. It impacts the deck’s structural integrity and long-term performance. Different materials affect durability and comfort. When making your choice, give the above things a lot of thought and be clear about your needs.

Investing in a high-quality composite decking brand is crucial. It provides lasting peace of mind and enhances your outdoor living experience. For further guidance on selecting composite decking, please contact us. EVODEK has a professional service team ready to answer all your questions.

FAQ

Can I Install Composite Decking Myself?

For experienced DIY enthusiasts, installing composite decking is feasible. However, the following points must be observed:

  • Strictly Follow Specifications: Installation must strictly adhere to the manufacturer’s guidelines. Failure to do so may compromise structural integrity and void the warranty.
  • Use Dedicated Hardware: Use the screws and hidden fasteners that the maker suggests or gives you. Incorrect screw types may damage boards or cause loose fastenings.
  • Allow Expansion Gaps: Make sure there is enough room between the boards so that they don’t bend or deform when the temperature changes. To ensure quality and safety, it is best to hire a skilled installation team for complex structure decks.

What Should I Consider When Purchasing Composite Decking for Poolside Areas?

Selecting composite decking for poolside areas requires prioritizing slip resistance. Choose styles with deep, textured slip-resistant surfaces. These uneven wood grain patterns provide sufficient friction. Some products also feature integrated drainage grooves that enhance water runoff and friction.

Is Composite Decking Hotter than Wood Decking?

Dark composite decking surfaces may get hotter than natural wood when they are in full sunlight. Therefore, in hot climates, opt for light-colored shades like light brown, beige, or light gray. These colors absorb less heat, resulting in significantly cooler surface temperatures. You can also provide shade for your deck using pergolas, umbrellas, or greenery.
