Commercial Exterior Cleaning

Commercial Exterior Cleaning – South East 

So, let’s say your building is really, really dirty on the outside. First, you have to figure out what the building is made of. Is it made of bricks or some other stuff?

Next, you should look at what kind of dirt is making it look not nice. Is it mud? Is it icky green stuff? Or something else?

After you know these two things, you can look for a cleaning company that knows how to clean buildings like yours. They will know what kind of special soap and machines to use to make it look all shiny and new!

And that’s how you pick the right people to clean your building’s outside!


Which is used on many buildings these days usually requires the Soft Wash method of cleaning. And because his method is fairly new in the UK and you should find a genuinely competent company to carry out this task – you can find fully trained and equipped companies here. Because Soft washing is ideal for organic matter removal from render when done properly.

Stone which has been used throughout the centuries will likely need to be cleaned by a Doff High Temperature Steam Cleaner. Doff equipment have been approved by English Heritage because they cannot damage the stone façade. Doff is ideal to remove organic matter and man made stains such as paint, graffiti etc. Should there be other contaminants such as carbon staining usually black in colour then it is highly likely you would need to use HF20 to soften it up before applying high temperature steam.

Cladding, metal, steel, aluminium, plastisol coated, painted and even powder coated, what methods should be used to clean them? Mostly Soft Washing will be required to clean off the organic matter. Where these surfaces have suffered from UV damage and are powdery to the touch, a product specified by architects such as The Purple Rhino 3 Step System will need to be used because it ensures the surfaces are brought back to original colour and protected with hydrophobic coatings to prevent further UV degradation from occurring.

Because Cedar wood cladding is becoming very popular these days on modern apartment buildings and offices. And therefore, Soft Washing is the very best way to clean off any unwanted organic build up.


Again because the Doff steam cleaner is often found to be the perfect tool for getting rid of unsightly organic matter

Concrete, the trusted and well known pressure washer, is often used to blast away dirt and grime from this hard surface material.

Also consider what type of training does the commercial building cleaner company offer its employees. They should have all the basic training such as WHR (working at Height Regulations) Ladder Training, Manual Handling Training, Asbestos Awareness Training, Safety Harness Training, IPAF, PASMA as well as specilised “how to” courses such as Stonehealth Approved or SoftWash Systems Certified Applicator training course which ensure the user of their equipment has been trained to use it safely and effectively.

And therefore, most commercial exterior cleaning companies will provide you with a site survey and a fully written itemised quotation.

What our Clients Think

See all testimonials
  • Purple Rhino operate a first class and professional cladding & facade cleaning service. My opening dialogue with Darran Smith was concise and prompt and he certainly did not employ the irritating ‘hard sell’ tactics with constant phone calls and emails chasing the contract. Darran left our company to decide in our own time when and how we would have the building’s facade cleaned.
