Bespoke cleaning solutions for our clients.

London's DOFF Cleaning Specialists

One of the most effective and powerful techniques we use, DOFF cleaning produces outstanding results every time. The system uses super-heated steam to efficiently remove stains, discolouration and organic matter from the exterior surface of a building. Suitable for use on a wide variety of materials, it can be used to completely transform the façade of a property and return the building to its original aesthetic condition.

What is DOFF cleaning?

DOFF cleaning is a fast and efficient cleaning process that uses a ‘DOFF’ machine. The DOFF machine heats water to a much higher temperature than conventional steam cleaners. The machines are able to heat steam to 150 degrees Celsius. At this temperature, steam is incredibly effective at removing stains, discolouration, organic matter and paint from the exterior surface of a building.

DOFF steam cleaning is widely used to aesthetically renovate the façades of domestic and commercial properties. The process allows operatives to clean and restore surfaces quickly and easily. The DOFF steam cleaning system is mobile and can easily be transported to different locations. This makes it ideal for use on-site and allows operatives to use the resource wherever it is needed.

As DOFF cleaning uses low-pressure water, the substrate is not damaged during the cleaning process. This is a very important property of the cleaning system and makes it ideal for use with modern render and other commonly utilised building materials.

What can DOFF cleaning be used for?

DOFF cleaning is a versatile and effective method of restoring and renovating property exteriors. It has a wide range of applications, including paint and graffiti removal, algae cleaning and stain removal. It can be used on both domestic and commercial properties and, when the correct equipment and training are utilised, can be used at height.

Paint Removal

One of the most common applications for DOFF cleaning is paint removal. Paint needs to be removed from buildings for a variety of reasons. In some cases, peeling paint needs to be cleaned off before redecoration work can begin. In other cases, the paint may need to be removed because it is creating an eyesore or has been applied as an act of vandalism.

The DOFF high-temperature, low-pressure steam cleaning system can effectively remove most internal and external oil and water-based paints. It can also be used to remove varnishes and bitumastic and thermoplastics coatings without causing shock or harm to the substrate.

Graffiti Removal

Graffiti is a serious issue for many property management companies. Finding an efficient and effective way of removing graffiti can help these companies to keep their buildings in good condition.

The DOFF steam cleaning system is often used to remove stubborn graffiti stains from interior and exterior surfaces. By combining the technique with either chemical or mechanical solutions, a wide variety of paints can be quickly removed from all areas of a building. These include spray-paints, cellulose, lead-based and water-based paints.

Algae Cleaning

Algae is commonly found growing on exterior surfaces. If left untreated, it can cause serious discolouration over time. With the use of DOFF steam cleaning systems, we are able to effectively and efficiently remove algae from all types of brick, stone and cladding without the risk of damage to the substrate.

Carbon Staining Cleaning

When carbon monoxide builds up on the surface of a substrate, it can begin to eat away at the stone, altering its physical appearance. Once this is removed, the restored stonework will have a fresh, renovated look and the façade of the property will be restored to its original aesthetic condition.

What Our DOFF Cleaning Customers' Say

B. Vincents

Property Manager

Spectrum's Doff Cleaning service has compltely rejuvinated my brick property. The building had clearly been discoloured through the years, but I did not realise the severity of the discolouration until after Spectrum steam cleaned the building. Needless to say, Spectrum's Doff Cleaning services exceeded my expectations.

T. De Beavers

Property Manager

I use to believe the only way to properly clean grime off of the exterior of a building was through a power washer, but Spectrum's Doff Cleaning service proved the best results come from steam! Thank you to the team of experts at Spectrum for helping clean and preserve my property.

Why use Spectrum for DOFF cleaning?

Spectrum operatives have extensive experience working with the DOFF cleaning system. They’re able to fully utilise the technology to remove paint, algae, pollutants and other discolouration from the exterior of a building. If this staining is located in an elevated position, our team can use their expertise in access to reach the problem area and make it look as good as new.

Protecting our listed buildings

The system used by Spectrum is the only one accredited by English Heritage for use on their protected buildings. Using steam rather than pressure to remove discolouration and staining helps to protect surface textures and finishes and minimises damage to the buildings. This is one of the main reasons that Spectrum use the DOFF steam cleaning system for specialist work in London and the South East.

A Bespoke Approach

Spectrum combines the use of DOFF cleaning with our own bespoke, patented equipment. These specially designed pieces dramatically increase our reach, allowing our operatives to reach areas that would otherwise be impossible to access. This approach lets our teams manipulate high-temperature, low-pressure steam like nobody else.

Easy Access

Many of the DOFF steam cleaning jobs we take on require our teams to work at height. Removing paint, algae, staining and graffiti from high-rise buildings and other large properties is often only made possible by using rope access, MEWPs and specialist equipment. Spectrum has extensive experience using all types of access equipment. This means our operatives are able to reach every corner of a building without the use of scaffolding, something that can save our clients a considerable amount of money.

A lot of the time, our patented modular pole system enables us to clean from the safety of the ground. When rope access is required, our IRATA trained abseilers are on hand to support the ground-based cleaning team.

A Skilled and Experienced Team

Over the years, Spectrum has used DOFF cleaning to remove stains, discolouration and organic matter from a number of complex elevations. This extensive experience and proven track record means we are the perfect choice for your next cleaning project.

Why do we recommend cleaning stains on stone with high-temperature steam instead of pressure?

1. Unlike pressure, steam will not leave hairline cracks on the substrate's surface. 
2. Steam kills and draws out the organic matter in the pores of the substrate. 
3. As steam is gentle, it can effectively clean your stone without harming the stone's patina

We often discuss how we utilise the powers of DOFF and TORC machines to clean stone facades, but what is the difference between these cleaning methods??

1. The DOFF machine emits extremely heated steam to clean masonry, while the TORC machine utilises a swirling vertex of compressed air, fine abrasion and water.
2. The DOFF machine is our preferred method for cleaning the majority of stains and organic matter from stone buildings.
3. We utilise the TORC machine, though, when the stains are deeply ingrained into the pores of the stones, including efflorescence!

Experiment time! Take a piece of string and pull it as hard as you can until it snaps. Now take two pieces of string and pull them- which one was easier to break?

Just as two strings are stronger when pulled than one, we have found that combining two cleaning systems when removing deep stains on stone and brick properties is better than just one! ?

By first applying the steam from a DOFF machine and then the swirling vertex from a TORC/Jos machine, we are able to remove deeply engrained stain from even the most porous of property facades! ?

Spectrum is at Piccadilly Circus, London

Are yellow, orange, or green patches growing on the stone elements of your property?

These are most likely spores- microscopic organic matter that floats in the air and builds on porous surfaces. You can try to paint over it, but that most likely will only be a short-term fix as it traps moisture and forms unappealing blisters.?

A few years ago, I tested every method under the sun to try to find the best solution for removing spores. The best solution I found was the extremely heated steam from a DOFF machine! To make this system more effective, I even developed and patented brushes to use with the DOFF machine!?
