Other Cleaning Services 

Window Cleaning & External Building Cladding Cleaning 
A regular window cleaning service is available including soffit, fascia and guttering cleaning using the Reach & Wash System, as well as manual application where necessary. 
This also extends to exterior building cladding and entrance canopy cleaning to remove all surface contaminates such as bird droppings, etc. 
The Reach & Wash System uses demineralised water, leaving a streak free finish. 
Working at height is not generally an issue using this system, but if required, we can hire access plant equipment. 
Building Exterior Cleaning using the DOFF & TORQ System 
These two systems are primarily used for cleaning and paint removal from both historic and modern masonry surfaces. 
The DOFF system produces a spray of high temperature water at up to 150ºC and is most suited to the removal of flexible soiling and coatings. The TORC system combines compressed air, fine abrasive and water and is best suited to the removal of brittle soiling and coatings. 
When correctly used, the output of both systems can be regarded as of extremely low risk to the environment. Separate consideration must be given to what is being removed in the cleaning process and whether that contains any hazardous matter. 
Method Statements are available for both systems which give general guidance and precautions for use. 

Infection Control Cleaning 

Here at GNC Contract Services, we act fast to secure areas of risk quickly and effectively. 
Using the very latest in electrostatic sprayer technology (Fogging), our systems deliver environmentally friendly disinfectant to eliminate Coronavirus (SARS-associated), Human Coronavirus (VR-740), Canine Coronavirus (VR-809) as well as RNA and DNA fragments. 
Combined with our extensive knowledge of working within both the Public and Private sector, you can rely on GNC to deliver swift cleaning and decontamination services of the highest possible quality for businesses and organisations of any size.
