Graffiti Removal from Signage

Signage represents a significant investment — and graffiti on a billboard, hoarding, or pylon sign doesn’t just look bad, it directly undermines the message your signage is there to deliver.

Signage comes in many forms and materials, and graffiti removal needs to be approached carefully to avoid damaging what is often a costly asset. The wrong cleaning solution or technique can lift printed graphics, discolour substrates, or permanently mark surfaces that are expensive to repair or replace.

All graffiti removal from signage is carried out by hand — pressure washing is not used on these surfaces. Hand application gives our technicians full control, ensuring the graffiti is removed without risk to the signage beneath.

Billboards and construction hoardings are high-visibility targets — large, accessible, and often located in busy public areas. Most modern billboards and hoardings feature digitally printed vinyl graphics, which require a particularly careful approach.

A specialist cleaning solution suited to the printed substrate is selected and applied carefully by hand. The solution is chosen to break down the graffiti substance without lifting, cracking, or discolouring the printed graphic beneath. Careful hand removal follows, using appropriate tools and technique — no abrasive materials, no pressure washing.

The goal is always to preserve the integrity of the printed graphic and the substrate it sits on, avoiding the cost of a reprint where possible.

Pylon signs vary widely in their construction and surface materials, and our approach is tailored accordingly. Common pylon surface types include:

Plastics and acrylic panels:
Plastic surfaces require delicate treatment — certain solvents can cloud, craze, or permanently mark plastic and acrylic if not carefully selected. Our technicians choose cleaning solutions specifically suited to the plastic substrate involved, applied gently by hand.

Stainless steel and aluminium:
Metal pylon surfaces are generally more robust but still require care to avoid surface marking or discolouration. Appropriate cleaning solutions are applied by hand, with technique matched to the specific metal finish — whether brushed, polished, or powder coated.

Painted pylon surfaces:
Where pylon panels have a painted finish, the approach mirrors our painted surfaces process — assessing whether the paint is in good enough condition to clean, or whether touch-up repainting is the more practical solution. Colour matching and repainting to architectural lines is available where needed.

• Hand application only — pressure washing is rarely used on signage surfaces
• Surface assessment on arrival — the signage material and graffiti type are identified before treatment begins
• Specialist cleaning solutions selected to match the specific substrate — printed vinyl, plastic, metal, or painted surfaces
• No abrasive materials — protecting the signage asset is always the priority
• Colour matching and repainting available for painted pylon surfaces where cleaning isn’t the best option
