Professional decking cleaning services

Specialist decking cleaning North East: we revive timber, composite, and hardwood surfaces using professional-grade restoration techniques that protect your investment.

Wood decking cleaned and brightened along house – before and after look

Restore your decking to its natural beauty

Maintaining outdoor timber requires a precise balance; too much pressure destroys the delicate wood fibres, while too little fails to eliminate deep-seated organic growth. What makes our approach impactful is the use of tailored flow rates and professional detergents that break down algae at the root. Whether it’s softwood needing a total revival or composite decking that has lost its lustre, we ensure a safe, uniform finish without the risk of furring or splintering.

Decking Types We Clean:

  1. Softwood decking (pine, spruce)

    Gentle cleaning to remove algae and grey weathering, followed by optional oiling or staining.

  2. Hardwood decking (oak, teak, iroko)

    Careful cleaning that preserves the natural oils and grain without causing surface damage.

  3. Composite decking

    Low-pressure cleaning to remove algae, mould and staining without scratching the composite surface.

  4. Pressure-treated decking

    Safe cleaning that won't strip the preservative treatment whilst removing organic growth.

  5. Cedar decking

    Delicate cleaning to restore the natural red tones without damaging the soft wood fibres.

  6. Raised and tiered decking

    Safe access and cleaning for elevated or multi-level decking structures.

  7. Decking balustrades & handrails

    Thorough cleaning of railings, spindles and handrails to match the deck surface.

  8. Grooved decking boards

    Specialist cleaning to remove algae and dirt from anti-slip grooves without damage.

  9. Weathered & grey decking

    Restoration cleaning to remove grey oxidation and reveal the natural wood colour beneath.

  10. Previously stained or oiled decking

    Careful cleaning and optional re-treatment to refresh the protective coating.

Questions & Answers

  • Not when it's done correctly. Wood is delicate and requires low-pressure cleaning with controlled techniques. High pressure causes splintering, furring and damage to the grain. We use the right pressure and angle to clean effectively whilst protecting the wood fibres. Composite decking is more durable but still requires careful handling to avoid scratching.

  • Yes. Grey weathering is oxidation on the wood surface. We use specialist deck cleaners and brighteners to strip away the grey layer and reveal the natural wood colour underneath. The result can be dramatic - especially on softwood like pine. We then recommend oiling or staining to protect the restored wood and prevent it turning grey again.

  • Stain is essentially decking oil with a tint - it still behaves like oil but adds colour on top. The choice comes down to whether you want to keep the natural look of the timber (oil) or adjust the tone (tinted oil / stain). Some decking oils also contain biocides, which help tackle deeper imperfections and protect the timber against future organic growth. After cleaning, treating the deck with a suitable oil or stain helps reduce weathering, movement and surface breakdown.

  • A typical domestic deck takes between two and four hours to clean depending on size, condition and access. Heavily weathered decking requiring restoration takes longer. If you're having the deck oiled or stained afterwards, it needs to dry fully first - usually 24-48 hours depending on weather. We'll provide a timeline with your quote.

  • Absolutely. Green staining on composite decking is algae growth, particularly common in shaded or damp areas. We use specialist treatments and low-pressure cleaning to remove the algae and restore the original colour. Regular cleaning helps prevent regrowth - we can advise on maintenance schedules to keep your composite looking fresh.

  • Yes. We can clean over existing treatments or, if the coating is worn or peeling, strip it back and apply fresh oil or stain. We assess the condition first and recommend the best approach. If the existing treatment is in good condition, we'll clean gently to preserve it. If it's failing, we'll remove it properly before re-treating.

David and Monica were recommended to me by a friend who'd previously had work done by them, of whom she spoke very highly. David's knowledge and professionalism shone through. I had a few broken roof tiles replaced, some pointing and all moss removed from my roof, then treated. David and Monica went the extra mile, even cleaned my windows "properly" in case of any residue after roof treatment :-) A truly professional couple, hard working, perfectionists and would definitely recommend them :-)

What a lovely, hard working couple. Unfortunately because of the wet weather, cleaning roof of moss, spraying it after, cleaning all pvc and windows..instead of 1 day, took them 3 mornings. Always on time and cleaned up. Would definitely recommend them. Did a great job, especially the roof, not any sign of moss and as good as new. Thanx to both of you xx

Both David and Monica have done an amazing job on cleaning my sandstone house, wall and all facia boards/ guttering. Cost was fantastic value and knowledge/ professionalism was superb. We will absolutely have them return to clean our patio in the future, and have not hesitation to recommending them for all aspects of external cleaning! Thank you.

We had our driveway, conservatory, and back block paving cleaned by DMK Cleaning Solutions Ltd, and the results were truly jaw-dropping. Dawid and Monika were professional from start to finish — excellent communication, punctual, and left everything spotless. They didn’t just clean — they also sealed the driveway to help it last longer, and the attention to detail was fantastic. Everything looks like new again! All of this was done at a very competitive price. We couldn’t be happier and highly recommend DMK Cleaning Solutions Ltd to anyone looking for high-quality, reliable exterior cleaning.
