Specialist Cleaning for Complex Space
Building finished and floor fabrics require more than routine cleaning. For clients with an ACS office cleaning contract, specialist periodic works can be added to prolong the life or your building fabrics and finishes, whilst supporting safety and high quality presentation.
We offer specialist services including window cleaning, deep cleaning, carpet and upholstery care, hard floor maintenance, high-level cleaning, and exterior jet washing and graffiti removal. All works are delivered by highly-trained specialist teams using ISO-aligned procedures and eco-conscious methods.

Frequently Asked Questions
What counts as "specialist" cleaning?
Tasks beyond routine daily cleaning e.g., carpet and upholstery cleaning, hard floor restoration (scrub/strip/seal), kitchen and washroom deep cleans, high-level dusting, exterior jet-washing and graffiti removal, and coordinated pest control.
Do you provide specialist services as one-offs?
Specialist works are offered as add-ons for contract clients.
How do you decide the right method or products?
We assess surfaces, usage and risk, then specify methods and products to suit the material and environment, providing risk assessments and method statements where required.
Will specialist work disrupt our operations?
We plan our work to ensure there is no impact on business operations. External window cleaning can be carried out during office hours. Internal glazing is scheduled outside trading hours. Most other specialist tasks (e.g., deep cleans, floor restoration, high-level work) are booked for evenings or weekends. We phase by zone and use clear signage to keep people moving safely.
Can you use eco-conscious options?
Where suitable, we select eco-certified products, concentrates and microfibre systems, balancing sustainability with safety and performance.
