Decking Cleaning in London — Professional Results, Fair Prices
Professional decking cleaning in London restores weathered, slippery timber to its original appearance. We use carefully controlled low-pressure washing to clean without splintering or raising the grain, followed by optional treatment and oiling to protect the wood for years. Most decks take 2–3 hours.
Decking Types We Clean
Softwood Decking
The most common residential decking in the UK. Needs careful low-pressure cleaning to avoid splintering.
Hardwood Decking
Ipe, oak and similar — more durable but still needs surface-appropriate technique to protect the finish.
Composite Decking
Low maintenance but still benefits from periodic cleaning to remove algae and surface grime.
Our Process
1. Assessment
We check timber condition, existing stain or oil, and identify algae or green growth — common on shaded decking.
2. Low-Pressure Wash
Controlled pressure removes dirt and algae without raising the grain or causing splinters.
3. Treatment & Oiling
Optional decking oil or treatment seals and protects the timber after cleaning.
Why low pressure matters: high-pressure washing on timber raises the wood grain and can cause splintering — a safety hazard underfoot and a finish that's harder to treat afterwards. Our controlled approach cleans thoroughly without that damage.
Why Professional Cleaning
Algae and moss on decking are a genuine slip hazard, especially on shaded or north-facing areas. Beyond safety, incorrect DIY pressure washing is one of the most common causes of damaged decking — once the grain is raised or the surface splintered, it's difficult to fully restore. Professional low-pressure technique avoids that risk entirely.
