 Trustindex verifies that the original source of the review is Google. I can’t speak more highly of James, Ethan and Ivor. They worked solidly for 2 whole days to completely transform our old driveway and patio which was full of weeds creeping through the bricks and stained over years of wear and tear. They then sanded between the bricks to try and prevent the return of the weeds. In addition to this they cleaned our solar panels, treated the roof, and cleaned the external walls of the house including a large stain on the front which I was worried wouldn’t come off. The house looks brand new and several friends and family have commented particularly on the transformation of the patio and paths all around the house. The amount of work they have done in just two days is very impressive. These guys are polite, friendly, professional and just all round lovely people. Thanks fellas - will be using you again in the future for sure and recommending you to others.

 Trustindex verifies that the original source of the review is Google. I can thoroughly recommend Cleaning Doctor. We received an excellent service from start to finish — reliable, professional and extremely thorough, with real attention to detail.

Everything was carried out exactly as promised and to a very high standard. They were also a genuine pleasure to deal with: friendly, courteous, straightforward and completely dependable.

It’s refreshing to find a company that combines excellent workmanship with genuinely good customer service. We wouldn’t hesitate to use Cleaning Doctor again and would thoroughly recommend them.

Five stars from us.

 Trustindex verifies that the original source of the review is Google. I can totally recommend this Company for gutter cleaning after some work they carried out for me .
The owner James was excellent in every way and deserves 6 stars if that was possible!  His friendly approach, excellent work and reasonable charge are so appreciated in this cynical age.
Many thanks James

Real examples of our decking cleaning expertise.

Our Process

Safe Restoration, Not Destruction

We use specific techniques to clean decking without stripping the wood surface.

1. Treatment & Cleaning

We start by applying a professional cleaning agent to break down algae and grime. We then use a flat-surface rotary cleaner to gently lift the dirt from the grooves.

Pre-Treatment: Loosens stubborn dirt

Rotary Clean: Consistent, streak-free finish

Gentle Pressure: Protects wood grain

2. Smartseal® Sealing & Protection

Once the deck is thoroughly cleaned, we can seal it with premium Smartseal® wood sealer. This seals the wood, enhancing the colour, repelling water and prevents green growth.

Quality protection: Weather resistance

Water Repellent: Preserves colour and integrity

Anti-Slip

Removes biological slime.

Wood Care

Nourishes dried timber.

Why Clean Your Decking?

The benefits of our professional decking restoration services.

Restore Safety

Algae and moss make wet decking incredibly slippery and dangerous. We remove this hazard to make your deck safe to walk on year-round.

Gentle Cleaning

We use rotary head cleaners and appropriate pressure settings to clean the wood deeply without "furring" or damaging the delicate fibres.

Remove Stains

Our process removes ingrained dirt, food stains, and general grime, revealing the natural wood grain beneath.

Composite Decking

We are experts in cleaning modern composite decking materials, ensuring they are cleaned safely according to manufacturer guidelines.

Smartseal® Sealing

After cleaning, we can apply premium Smartseal® wood sealer and wood protector to protect it from UV rays and rot.

Prevent Rot

Removing moss and algae allows the wood to dry out properly, preventing the damp conditions that lead to wood rot and decay.

Price Promise

The price quoted includes all labour, equipment, and cleaning solutions – no hidden extras. A deck in East Belfast gets the same fixed, upfront quote as anywhere else we cover.

Fully Insured

We carry full public liability insurance, giving you complete peace of mind while we work on your property.

Frequently Asked Questions

Common questions about our decking cleaning services.

Will pressure washing damage the wood?

It can if done incorrectly with too much pressure or the wrong nozzle. We use professional rotary flat surface cleaners and adjust the pressure to gently lift dirt without "furring" or splintering the wood.

Can you clean composite decking?

Yes, absolutely. Composite decking requires careful cleaning to avoid scratching or damaging the finish. We use soft washing techniques and appropriate cleaning solutions safe for composite materials.

Will it be slippery afterwards?

No, quite the opposite! The primary cause of slippery decking is the layer of algae and moss. Once we remove this biological growth, the natural grip of the wood or composite is restored.

Do you oil the deck as well?

Yes, we offer an optional oiling service. Once the deck is clean and fully dry (which may require a separate visit), we can apply high-quality decking oil to nourish the wood and protect it from the elements.

How often should I have my deck cleaned?

We recommend a professional clean once a year, typically in spring, to remove winter grime and algae build-up, ensuring your deck is safe and looking its best for the summer.

Do you seal the deck as well?

Yes, we offer an optional sealing service, using premium Smartseal® deck sealer. Once the deck is clean and fully dry (which may require a separate visit), we can apply to enhance appearance, protect against weathering and green growth, and prolong the lifespan of your decking.
