The importance & benefits of professional decking cleaning

In Bristol, humidity and rain can quickly affect wooden or composite surfaces. Regular professional cleaning helps prevent these effects and keeps your decking in excellent condition, season after season:

Here’s why regular decking cleaning is essential:

Safe, non-slip surface

Moss and algae build-up can turn your deck into a dangerous area. Professional cleaning completely removes them, allowing you and your family to enjoy a safe space, no matter the weather.

Visible and long-lasting results

We use professional equipment and eco-friendly solutions that clean deep without damaging the material. Your decking regains its natural look and stays cleaner for longer.

Easy, worry-free maintenance

After professional cleaning, your deck becomes much easier to maintain. Dirt doesn’t settle as quickly, and its clean appearance lasts with minimal effort.

Long-term savings

A properly cleaned deck won’t need costly repairs or premature replacement. It’s a small investment that brings visible and lasting benefits.

How we clean your decking step by step

Every deck is different, so we adapt our cleaning method according to the material, level of dirt and overall condition of the surface. Here’s how our professional cleaning process works:

Detailed surface assessment

We check the type of material, level of dirt, shaded areas and any possible moisture issues. Based on these details, we choose the optimal combination of pressure, temperature and cleaning solution.

Application of specialised solution

We spray a professional solution that penetrates deeply, dissolving moss, algae and organic dirt without damaging the surface. The solution is left to act for a few minutes to loosen all built-up deposits.

Controlled cleaning with dedicated equipment

We use professional machines with adjustable nozzles and pressure control, tailored to the type of material. For wooden decking we use low-pressure or steam cleaning, while for composite we apply a steady medium pressure, ensuring an even, streak-free result.

Finishing, protection and final recommendations

After a thorough rinse, we carefully inspect every area to ensure an even result. On request, we apply a protective coating to extend the effect of the clean and provide simple maintenance advice for long-lasting results.
