Steam Cleaning

With our Doff cleaning system we can clean historic dirt and grime off the most delicate of surfaces such as statues and monuments and sandstone. 

The Doff Steam Cleaning

The Doff Steam Cleaning System effectively removes paint, biological matter and general dirt and grime without causing harm or shock to the substrate.

Making a Visible Difference

Ideal for use on large buildings such as courthouses, churches & hotels, The DOFF cleans stonework and masonry using high-temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.

Using the Latest Technology

The DOFF System is unique in achieving temperatures of up to 150 degrees at the nozzle end, making it a super-heated water system.

No Harmful Chemicals

As the Doff uses super-heated steam, there are no harmful chemicals being used.

Designed and developed to effectively remove paint, biological matter, general dirt and grime, without causing harm or shock to the substrate.

Graffiti Removal

All of our graffiti removal products are REACH compliant, biodegradable and environmentally sustainable.

Wall Graffiti Cleaning - Before
Unfortunately, graffiti is common on prominent buildings such as courts, high-rise flats and other brickwork establishments in cities across South Wales & South-West England such as Swansea, Bridgend, Cardiff & Bristol.
Wall Graffiti Cleaning - After
We only use sustainable substances when removing graffiti, ensuring we do not damage any surfaces on signs, doors and woodwork, among others, throughout the cleaning process, all whilst remaining environmentally-friendly.

We had Simon and his team to soft clean our pebble dash on the front of our house. He did an amazing job. We were thinking of painting it as it was looking a bit drab but when Simon had cleaned it we found it was like new and didn’t need painting. Thank Simon

I asked Simon STR and his team to come in and clean some guttering and facias around my house before the winter and he did an amazing job. Some of the areas were really hard to reach but Simon had no problem with this. They even cleaned all my paths and patio afterwards and left everything spotless. Thanks Simon - Fantastic job.
