The Ultimate Guide to Composite Decking: Benefits, Installation Tips, and Maintenance Tricks

Designing your deck is an important part of building your own house, as it’s where you will create some of your best memories. An outdoor deck is not just an extension of your home, but a space where you will be spending time with your loved ones.

For this reason, it’s important to make informed decisions when you’re designing a deck, and choosing the right materials is the first step. You can go for timber if you want to keep a classic, natural look; however, if you’re looking for durability and easy maintenance, composite decks will be just right for you.

Why You Should Choose Composite

Composite decks are usually made with recycled plastic and timber particles and binding agents. In addition to using sustainable materials and thus reducing environmental impact, many other reasons make composite decking the top choice for many homeowners. 


The timber deck consists of natural materials, so it’s more vulnerable to damage. Regular maintenance is required to maintain a wooden decking and prevent it from discoloration, splintering, and developing mold.

Compared to this, composite decking is more prepared for all types of “enemies” – harsh weather conditions, UV exposure, or staining. You won’t have to worry about mold or mildew, discoloration and splinters – composite decks are designed to be highly resistant.

Easy to Maintain

Because of lower durability, wooden decks are much harder to keep healthy and beautiful. Regular check-ups are required to identify and eliminate problems like pest infestations or water damage. They can quickly deteriorate without proper upkeep, so the maintenance costs are much higher when you choose natural materials.

Routine inspections aren’t necessary when you’re dealing with a composite deck. It requires lower maintenance because it’s specifically created to be more durable than timber, and a simple wash with a mild detergent might be all you need to keep your deck clean. 

As we said, getting rid of mold or insects won’t be something you’ll have to do if you go for composite decks. Besides that, they don’t need sealing or staining, overall requiring minimal extensive repairs and no frequent maintenance.

Planning and Construction

Before starting construction, you must carefully plan out your outdoor space. Carefully plan out the design to match your preferred aesthetic and choose the highest-quality materials considering specific features, such as color and texture.


Following the manufacturer’s guidelines is crucial during the construction process to guarantee safe and sound decking. Always wear appropriate safety gear, like gloves, eyewear, and dust masks. If needed, ask for professional help, as the materials can be heavy and must be handled carefully.

The first step is to install the substructure that’s created with strong and durable materials. If we think about British weather, it’s obvious that installing composite decking in London requires pressure-treated lumber for the substructure, as moisture damage can seriously threaten it. Use the guidelines to determine appropriate joist spacings and fastener placements.

How to Maintain


Chemical cleaners and pressure washing should be avoided on composite decking. Regular sweeping to remove leaves and debris and periodic washing with soap and water solution should be absolutely enough to keep your decking fresh and healthy.

Preventive Maintenance

Even though composite decking doesn’t require frequent inspection, you’ll still need to occasionally check it up. Regularly check for loose bolts and fasteners, scratches and cracks on the surface. Ensure that mold doesn’t develop, and if it does, use a specific composite deck cleaner or a solution of water and vinegar to eliminate it. 

Moisture absorption and potential decay can be avoided by sealing cut ends with a protective coating. Applying UV-resistant sealant to surfaces will prevent sun exposure from damaging the decks. 

Seasonal Tips

Snow and ice can be dangerous and must be regularly removed to avoid accidents. As metal can damage the surface, you need to use appropriate shovels and ice scrapers not to scratch your decks.

In summer, adapt sunlight exposure and airflow accordingly to maximize ventilation and avoid mold or mildew growth. Cover outdoor furniture and place them on protective mats to avoid sun damage and scratches.

In Conclusion

You can clearly see that composite decking is far superior to natural lumber. Especially in London, where moisture damage can be a real threat, choosing composite will help you save a lot of time, energy, and financial resources.

As long as you follow the manufacturer’s instructions every step of the way during installation, regularly clean the deck to remove debris, and occasionally check for issues, these sustainable materials will help you build an outdoor space that will last for years to come.
