Why Choose GLOSSVEX?
Slip Hazard Removal
Algae and green mould make decking dangerously slippery. Our treatment eliminates the slip risk and keeps your family safe.
Timber & Composite Safe
We use correct pressure levels and cleaning agents for each decking type — no splitting, lifting, or damage to fibres or boards.
Restores Natural Colour
Weathered grey timber is transformed back to its original warm tone. Composite decking regains its manufactured colour and texture.
Oil & Re-staining Available
After cleaning, we can apply specialist decking oil or stain to nourish the timber and protect against UV, rain, and foot traffic.
Mould Treatment
We apply a post-clean fungicidal treatment to prevent the rapid return of black mould and green algae.
All Sizes Covered
From small garden decking to large multi-level structures and commercial outdoor areas — we cover all sizes and configurations.
Our Process
We assess the decking material (softwood, hardwood, composite) and condition to determine safe pressure settings and the right cleaning solution.
A specialist decking cleaner or wood brightener is applied and left to dwell, breaking down grey weathering, mould, and embedded dirt.
We pressure wash using a wide fan nozzle at a safe distance to lift grime without raising timber grain or damaging composite fibres.
Edge boards, spindles, and railings are cleaned with appropriate hand tools to ensure a thorough, even finish throughout.
A post-clean mould inhibitor is applied to protect against rapid regrowth of algae and black mould between services.
Optional oiling, staining, or sealing is applied once surfaces are fully dry to protect and enhance the appearance of the decking.
Frequently Asked Questions
Can you clean composite decking?
Yes. Composite decking has different requirements to timber — we use lower pressure and appropriate composite-safe cleaning agents to clean without damaging the surface texture or colour.
Will cleaning remove the grey weathering from my timber decking?
Yes. Greying is caused by UV damage and surface oxidisation. We use specialist wood brighteners that restore the original warm colour of the timber beneath the grey layer.
How often should decking be cleaned professionally?
Most decks benefit from a professional clean every 1–2 years. Gardens with heavy shade or overhanging trees may need more frequent attention as moisture and organic debris accelerate biological growth.
Do you re-oil or stain decking after cleaning?
Yes — we offer oiling and staining as an add-on service. Oiling nourishes and protects the timber, extending its life significantly. Staining can also refresh or change the colour of the wood.
Is it safe to pressure wash decking?
Yes, when done correctly. The key is using the right pressure and the correct nozzle for the material. Too high a pressure on softwood can raise the grain. We have the experience and equipment to clean safely every time.
