Cleaning made clear
A service shaped around your workplace
We look at the height, type of glazing, access and the best time to work without getting in anyone’s way. If specialist access is needed, we will explain what is involved and provide the relevant safety information before work starts.
Good office cleaning should be straightforward. We agree what needs cleaning, how often it should be done, when our team can get in and who you can speak to if something needs attention.
During a free site visit, we look at the busiest areas, opening hours, washrooms, kitchens, floors and any extra services you may need. We then give you a clear plan and price, including how standards will be checked and what happens if something is missed.
Regular cleaning and the jobs done less often
Your cleaning plan will separate everyday jobs from weekly, monthly and one-off work. This helps you compare quotes properly and avoids surprises later.
We also think about noise, confidential areas, kitchens, busy washroom times, deliveries and the parts of your office that visitors see first. If keys, passes or alarm codes are needed, we agree a safe and simple way to manage them.

Common questions
What decision-makers ask
Can the work take place outside office hours?
Yes. We can discuss early-morning, daytime or evening cleaning. We will agree access, alarms, security arrangements and the time available before work begins.
Will we receive a written cleaning plan?
Yes. Your plan will list the jobs to be done and how often they will be completed, so you and the cleaning team know exactly what is included.
What happens if a task is missed?
Your agreement will explain who to contact, how the problem will be put right and how we will check that it has been resolved. The exact timings are agreed for your office.
Can this be combined with other cleaning services?
Yes. You can bring several Mainstream Cleaning services together, with each one clearly listed and priced.
How is pricing worked out?
The price depends on the size and use of the building, how often you need cleaning, the hours that suit you, access and any supplies or extra services. A free site visit helps us give you an accurate quote.
What is the best way to get started?
Request a free site visit and tell us the postcode, approximate floor area, how often you need cleaning and the times that suit you. We can then confirm whether we cover the area and put together a clear plan for your office.
