Commercial Graffiti Removal in Exeter, Devon and Region

Graffitti on brick, concrete, metal shutters and shopfront detracts customers and can compromise your brand image. Most property owners and managers want a fast graffiti removal response to restore their entrance or building. 

Our professional pressure cleaning and DOFF steam cleaning systems tackle graffiti by effectively and safely removing the solvent without harming the substrate of the surface. 

As one of the leading professional exterior cleaning companies in Devon and Somerset, our team has a breadth of experience working with facility managers and property owners when it comes to emergency, rapid-response commercial graffiti removal. 


Graffiti Removal From Surfaces 

Graffiti Removal From Brick  

The removal of graffiti from softer, porous materials such as brick and stone work, render or natural stone, is usually achieved through DOFF Steam Cleaning. This approach melts the solvent at high temperatures (around 150°C) without the need for high pressure therefore protecting the surface whilst removing the graffiti. 


Graffiti Removal From Concrete 

The removal of graffiti from harder surfaces such as concrete can be achieved using either pressure washing or DOFF Steam Cleaning. Depending on the solvents use and how recently the vandalism took place, a swift pressure washing system may achieve the result needed. Steam Cleaning can be used if the surface structure is softer or fragile and when the graffiti is older or made up of tougher solvents. 


Graffiti Removal From Shop Fronts 

The removal of graffiti from shop fronts is a careful and calculated process that requires a thorough assessment of the different surface types the graffiti is on. Most surfaces cope well with Steam Cleaning, so this is the most likely method, especially if some of the graffiti is on timber painted frames around the shop.


Graffiti Removal From Painted Walls 

The removal of graffiti from painted walls requires careful consideration due to the risk of damaging paint. Our usual method when cleaning graffiti from a painted surface is gentle steam cleaning and where necessary and safe, the use of a professional grade graffiti removal detergent.

Benefits of Doff Steam Cleaning & Gaffiti Removal

Insurance, Responsibility, Safety 

Moss, mould, lichen and algae growth is initially undetectable but as it grows compromises the structure of the building encouraging water ingress. Many insurance plans require regular external cleaning. As such, it should be part of a regular building maintenance schedule. 


Building Maintenance 

Regular cleaning maintenance mitigates against the risk of organic ingrowth which in turn leads to cracks, splits and flaking on cladding, facades and signage. Annual cleaning is a cost-effective contributing factor in protecting your building and investment. 


First Impressions 

Statistics show that your shop / business frontage has an overwhelming impact on whether people will even enter your premises. One UK study demonstrated that over 90% of shoppers claim the outside appearance of a retail store influences where they want to shop. 

Another study showed that similarly, 80% of shoppers would actively try a new shop simply because it was clean looking and inviting. 

Dirty windows, algae on cladding, and faded signage all signal poor maintenance and lower quality service. 


Pride & Team Morale 

Keep your team proud and happy to work in the building you manage. 

If your workforce has to enter a building each day that is dirty and unkempt, it impacts team morale and contributes to a poor attitude to work. High standards from the start improve the chances of ongoing high standards from your people.

FAQs - Doff Steam Cleaning Graffiti Removal


Pressure washing uses force to blast away dirt. While effective for some hard surfaces, it can damage render, dislodge pointing, strip paint and force water into cavities. 

Soft washing, instead of relying on force, it uses a targeted chemical reaction to sterilise and remove algae, lichen, fungi and mould. This means growth doesn’t return as quickly — and surfaces remain protected. 

Soft washing kills spores and organic growth at the root 

Pressure washing removes surface dirt but not underlying growth 

Soft washing is safer for delicate materials 

Longer-lasting results with biocidal protection
