Professional Steam Cleaning & Softwash Treatment for Block Paving

At Soft Washing UK, we specialise in professional block paving cleaning using a combination of high-temperature steam cleaning and specialist softwash treatments to remove dirt, algae, weeds, moss and stubborn black spot contamination.
 
Over time, block paving can become heavily stained by organic growth, atmospheric pollution and deeply embedded black spot. Traditional pressure washing often removes surface dirt but fails to fully eliminate the organisms responsible for staining and regrowth.
 
Our specialist cleaning process combines the power of steam with professional softwash treatments to deliver exceptional, long-lasting results while protecting the integrity of your paving.

What Is Black Spot on Block Paving?

Black spot is one of the most common and difficult stains found on block paving, patios and hard surfaces.
 
These dark black marks are caused by microscopic biological growth that becomes deeply embedded within the surface of the paving. Over time, black spot can spread across driveways, patios and pathways, making them look old, dirty and poorly maintained.
 
Unlike ordinary dirt, black spot cannot usually be removed through pressure washing alone.

Why Pressure Washing Often Fails to Remove Black Spot

Many property owners attempt to remove black spot using pressure washers. While pressure washing can improve the appearance of paving, it often only removes surface contamination.

The underlying spores and biological growth frequently remain within the paving surface, allowing staining to return.
Excessive pressure can also:
 
  • Remove kiln-dried jointing sand
  • Damage paving surfaces
  • Disturb surrounding areas
  • Accelerate surface wear
  • Encourage future weed growth
 
For this reason, we use specialist steam cleaning and softwashing techniques designed to tackle contamination at its source.

Our Steam Cleaning Process

Steam cleaning uses high temperatures to penetrate deep into the surface of block paving.
 
This process helps to:
 
  • Remove algae and moss
  • Kill weeds and spores
  • Break down organic contamination
  • Lift dirt and grime
  • Reduce the need for aggressive pressure washing
  • Prepare surfaces for treatment
 
The high temperatures achieved during steam cleaning provide a deep clean that traditional cleaning methods often cannot match.

Benefits of Steam Cleaning & Softwashing

Superior Black Spot Removal: Steam penetrates deep into the paving surface while softwashing targets biological contamination that pressure washing often leaves behind.

Advantages include:

Longer Lasting Results

By treating the cause of staining rather than simply removing surface dirt, our process helps keep paving cleaner for longer.

Reduced Regrowth

Softwash treatments help slow the return of algae, moss and black spot.

Improved Kerb Appeal

Clean block paving can transform the appearance of your property and create a positive first impression.

Environmentally Responsible Cleaning

Our process uses significantly less pressure than traditional cleaning methods while delivering outstanding cleaning results.

Driveway & Block Paving Restoration

In addition to cleaning, we can help restore block paving to its best possible condition.

Our restoration services may include:

This comprehensive approach helps maximise both appearance and longevity.

Frequently Asked Questions

1. Can black spot be completely removed from block paving?

Many black spot infestations can be significantly reduced or removed through professional steam cleaning and specialist softwash treatments. Results depend on the age and severity of the contamination.

Steam cleaning often provides a deeper biological clean while using less pressure, making it highly effective for treating algae, moss and black spot.

Results vary depending on environmental conditions, but softwash treatments help slow regrowth and maintain a cleaner appearance for longer.

Yes. Where appropriate, we can advise on or carry out re-sanding following the cleaning process.

Black spot is caused by biological growth that becomes embedded within the surface of the paving and gradually develops into visible black staining.

Softwashing UK was able to meet our gutter cleaning needs where others couldn’t. They were professional, reliable, and clearly knew what they were doing. They also did a fantastic job cleaning the render on our garage — it looks so much better now! Great service overall and I would definitely recommend them to others.

Many thanks to Softwashing UK for their excellent work at a reasonable price. We had some long standing algae stains on the rendering of the rear walls on our property in Cardiff. And the admin team were great in providing a quote, planning the work, and visited our property beforehand to check access to complete the work. Excellent team who know what they are doing. We are really happy with the results, better than we expected. Thanks.

We’ve used Softwashing a number of times over the past few years to clean the exterior of our house, gutters and patio. Every time it has been a fantastic service, always going above and beyond, whether it’s attacking a stubborn rust stain or taking time to explain the process. We have recommended them to friends and neighbours and using them every year is testament to how happy we are with the work they do. Thanks!

The service was great, Gavin arrived on the dot of eight o’clock and he then talked me through the process before starting. He worked diligently using a range of different techniques to address the various issues. At the end the render looked like new! Would definitely recommend and will have them back again when it needs doing again!

As a director of and on behalf of Wardour Court Management Company and residents I wish to record our thanks to Gavin and his team. The property is a sensitive building constructed of Chilmark stone, it had not been cleaned for some time and was looking the worse for wear. They were all extremely efficient and professional as well as very pleasant and easy to talk to despite the difficulties they encountered, which included having to work 17 hours on one of the days. All the residents I have spoken to have expressed how pleased they are with the result, as are the directors of Wardour Court Management Co. We would happily use this company again and are equally happy to recommend them to others.
