 Trustindex verifies that the original source of the review is Google. Paul arrived punctually at my home just prior to the expected time as arranged.
He took a few minutes to unload his equipment and explained in a professional and friendly manner exactly what he planned to do.
The work carried out was to a very high standard. I observed him checking each section of work as he progressed through the job to be undertaken.
I was highly pleased with the finished result and would have no hesitation in recommending his work.
It certainly was good value for the amount paid.

 Trustindex verifies that the original source of the review is Google. I recently moved house and needed a bit of sprucing up. I was recommended Paul and I’m glad I engaged his services. I needed the patio/driveway cleaned, the roof scraped and sealed, and the PVC fascia cleaned around the house.

Paul was quick to respond and took it from there. He was exceptionally prompt in getting me booked in, and the quote was more than reasonable compared to others in the area.

All the work was completed to a brilliant standard. The old sayings are true: if you pay peanuts, you get monkeys—and you get what you pay for. Paul is certainly no monkey; he is clearly a professional who knows exactly what he is doing. I considered buying the equipment and doing this myself, but it would have taken me weekends to complete to a much lower standard.

I am very happy I took this recommendation and hope you do the same. Fantastic service from a genuine and interesting gent.

Just finished difficult job cleaning and clearing my guttering in a 2 storey house which had not been undertaken for a few years. Paul stuck to his task professionally without pause leaving a very high standard of finish. Would recommend strongly and will request further jobs for cleaning shortly including roof cleaning.

 Trustindex verifies that the original source of the review is Google. Paul is a hard working and busy guy. He provides a first class job at a realistic price. He knows about refurbishing pressed concrete and we were introduced to him by the Smartseal agent in Northern Ireland. Your driveway and cleaning work is in safe hands. Thank you Paul

Our Process

Safe & Effective Soft Washing

We use a gentle chemical treatment process to clean your walls without high pressure.

1. Soft Wash Treatment

We apply a specialist biocide cleaning solution to the wall using low pressure. This breaks down the algae and dirt at a microscopic level.

Gentle Application: No damage to render

Kills Roots: Prevents rapid regrowth

Safe: Approved biodegradable chemicals

2. Controlled Rinse

After the treatment has dwelled, we gently rinse the surface with low pressure steam or water to reveal the clean, original finish.

Low Pressure: Protects mortar & pointing

Bright Finish: Instantly visible results

K-Rend Safe

Recommended cleaning method.

Long Lasting

Stays clean for years.

Why Choose Us For Walls?

The benefits of our professional external wall cleaning services.

Remove Algae

We specialise in removing red, green, and black algae that stains render and brickwork, restoring the original colour.

Safe Soft Washing

We use low-pressure "Soft Wash" technology to clean delicate surfaces like K-Rend without causing damage.

Prevent Damage

Moss and algae hold moisture against the wall, which can lead to damp penetration and frost damage if left untreated.

All Surfaces

We clean all exterior surfaces including render, pebble dash, brick, natural stone, concrete, and cladding.

Long Lasting

Our biocide treatments kill the root of the algae, meaning your walls stay cleaner for much longer than pressure washing alone.

Improve Kerb Appeal

Clean walls instantly brighten up your property, making it look well-maintained and increasing its value.

Price Promise

The price quoted includes all labour, equipment, and cleaning solutions – no hidden extras.

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 wall cleaning services.

Will cleaning damage my render?

No. We use a specialist "Soft Wash" method for rendered walls. This relies on cleaning agents rather than high pressure to remove dirt and algae, ensuring the delicate surface of the render is not blasted away or damaged.

Does it remove red streaks (algae)?

Yes, absolutely. The red staining often seen on light-coloured walls is Trentepohlia algae. Our treatment is specifically formulated to kill this algae and remove the red staining, restoring the wall's original bright colour.

How long will the results last?

Because our treatment kills the root of the biological growth, the results last much longer than simple pressure washing—typically 2-5 years depending on the location and environmental factors.

Is the chemical safe for my plants?

We take great care to protect your garden. We pre-wet and rinse down all nearby plants to dilute any overspray, and can cover sensitive areas. Once dry, the treated surface is harmless to pets and plants.

Can you clean brick and stone?

Yes, we clean all types of masonry including brick, natural stone, and concrete. We adjust our method to suit the material, ensuring a deep clean that removes carbon deposits, moss, and algae without damaging the pointing.
