Spectrum Specialist Support revitalise and protect facades of all descriptions, with our specialist techniques and products successfully restoring metal, glass and stone surfaces to an ‘as new’ condition.

Our range of services reduces on-going maintenance, restoration and refurbishment costs, whilst instantlyenhancing the appeal of buildings and architecture.We can offer full technical and practical support and arrange site surveys and reports throughout London and the South East.

The intensive but gentle technique of restorative cleaning offers an excellent cost-effective alternative to re-spraying (generally one third of the cost), or replacing (as little as one twelfth of the cost); ideal for dilapidation claims and often used at the end of a lease term by landlords and tenants.

Below we have included an introduction to metal cladding cleaning for your information. Be sure to contact our team personally for an immediate insight into the possibilities for your building.

Metal cladding cleaning

Expect exceptional results as standard from our specialist cleaning team, with recent high-profile success stories from around the City, including the final clean of No.5 Broadgate.

Our metal cladding restoration products have been designed specifically for commercial and industrial buildings, and will work on:

  • Anodised aluminium
  • Powder coated
  • Stainless steel
  • uPVC/GRP

We apply products by hand; work is performed without disturbing residents or tenants with noisy hand tools. Our products and methods enable us to remove dried out polymers, restore metal finish to near original, and create a near new effect without reducing the coating thickness on substrates.

The products we use contain preservatives, carnauba waxes, silicons and white buffing agents, so they are non-abrasive with a neutral PH and leave a protective layer.

Anodised aluminium

Aluminium is a light weight construction material that has allowed designers to shape and colour building projects since the 1950’s and 1960’s. Although aluminium does not rust, air pollutants, environmental exposure and surface contaminants cause cladding to become discoloured and develop pitting on its surface.

Anodised finishes are usually silver, bronze, gold or black and were used in the 1960’s to 1970’s. Since this time the colour choice has expanded as the anodising process has improved and anodised aluminium cladding is now used on high grade HQ buildings

Scratched or pitted aluminium corrodes from chemical reactions, so it pays to restore damaged aluminum promptly. Our systems restoratively clean damaged aluminium surfaces, removing corrosion to preserve structural integrity and aesthetic appeal.

Powder coated aluminium

Used since the 1980’s PPC finishes can be designed to individual specification and produced in any metallic or flat colour.

Aluminium cladding substrates can easily be damaged by inexperienced contractors using incorrect cleaning products and methods, and this damage may not become evident for 6 to 12 months.  At Spectrum we guarantee you remarkable, long-term results – removingcarbon staining, sealant leeching, airborne pollutants, grease and grime.

Stainless steel

Stainless steel is extremely soft and porous; when it ages the surface can appear sadly dull and light rust patches may develop. Some high-grade stainless steel finishes do have a lacquered coating which prevents this; unfortunately most stainless steel cladding does not.

Due to its nature, and like aluminium, stainless steel needs to be treated specifically and with care. Inexperience and sloppiness can be disastrous, and may not become apparent for 6-12 months after treatment. Spectrum has long been relied upon in the industry and has a history of success that can be depended on.


Many modern buildings incorporate uPVC - particularly around the windows. But even uPVC can become dull and dirty looking. When uPVC cladding turns dull, starts to tarnish or black marks appear, these problems are usually caused by exposure to UV light and the environmental conditions around the building or structure.

Spectrum have a specialised technique and approved chemicals to restore the appearance of uPVC, giving a near new look without the use of any abrasive products, and protecting against future problems.
