 Trustindex verifies that the original source of the review is Google. First class communication and work. Had to get work done while out of the country. Donal handled everything in what was probably a challenging job, no water to the house and the like. Delighted with the result and would highly recommend. John G

"I recently used The Cleaning Doctor for an exterior house cleaning and I couldn't be more impressed with their service. From the moment I reached out to them, they were professional and responsive, and provided me with a clear and detailed quote for the work.

The team that came to my home was friendly and efficient, and they did a fantastic job cleaning my siding, windows, and gutters. My house looks like new again! They even took the time to clean up after themselves and left my property looking spotless.

Overall, I highly recommend The Cleaning Doctor for anyone in need of exterior house cleaning services. Their attention to detail, excellent customer service, and affordable pricing makes them a top choice in the industry. Thank you to the team at The Cleaning Doctor for a job well done!"

 Trustindex verifies that the original source of the review is Google. We have used the Cleaning Doctor a few times over the years and we have always had a great experience from Donal and his team. If  it was a planned deep clean of carpets and furniture before the arrival of a new addition or after redecoration or an emergency clean because a bird flew in and messed up the whole living room we always had a promt and professional experience from the cleaning Doctor. Thank you Donal and Team.

 Trustindex verifies that the original source of the review is Google. I used the services of O' Sullivan Cleaning Doctor Kerry on my home in Killarney in preparation for some external painting (house, kerbs, and external walls) and was extremely impressed with the results. Not only was Donal`s team very polite, courteous, and worked very diligently to do a great job, but I really wondered whether I needed to paint at all when they were finished as they did such a great job. I whole heartedly recommend.

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.
