Homeowners are being urged to tackle a key garden maintenance job now or risk long-term damage to their decking as summer approaches.
With warmer weather on the way, experts say spring is the ideal time to clean and treat decking but warn many people are making simple mistakes that could leave surfaces unsafe, unsightly, or prone to rot.
According to experts from Artificial Grass Direct , one of the biggest issues is relying on quick fixes without properly protecting the wood afterwards. Colin Potts, decking industry expert said: “Many people think giving their decking a quick wash is enough, but without sealing or oiling it afterwards, the wood is left exposed to moisture and sun damage. That’s when problems start to develop.”
Here experts detail the mistakes householders often make and explain how to avoid causing lasting damage to your outdoor decking.
Common cleaning mistakes could cause lasting damage
Experts warn that improper cleaning methods can actually do more harm than good. One of the most common errors is using high-powered pressure washers incorrectly. While they can be effective, using too much pressure or holding the nozzle too close can strip the surface of the wood, cause splintering, and force water deep into the boards.
Another issue is the use of harsh household chemicals such as bleach or strong multi-purpose cleaners. These can weaken the wood’s structure and cause discolouration, using strong chemicals can also leave decking more vulnerable to the elements.
Instead, specialists recommend using a dedicated decking cleaner or mild soapy water, applied with a stiff brush and rinsed gently.
Hidden hazards homeowners often overlook
Beyond cleaning, experts say many homeowners miss key warning signs that their decking needs attention.
Dirt and debris trapped between boards can hold moisture, increasing the risk of rot, while shaded areas are particularly prone to algae and mould which can make surfaces dangerously slippery.
Loose nails, cracked boards, and soft spots in the wood are also signs of potential damage that should be addressed before the deck sees heavier use in summer.
Why spring is the best time to act
Timing is crucial when it comes to decking maintenance. Experts advise cleaning during mild, dry conditions, ideally in spring, to allow the wood to dry fully before applying protective treatments.
Cleaning during very hot weather can cause products to dry too quickly and leave patchy results, while damp or cold conditions can prevent proper drying and lead to further moisture issues.
Applying a protective oil, stain or sealant after cleaning is considered essential to help shield
“One simple job can make all the difference”
Taking the time to properly clean and treat decking now can significantly extend its lifespan and improve safety.
Colin added: “It’s a relatively simple job, but it makes a huge difference. When done properly, it not only improves how your decking looks but helps prevent costly repairs later down the line.”
