What clean glass does for you.
Windows are easy to forget until they are dirty, and by then they are quietly working against you. Kept clear on a cycle, they do the opposite.
A building that looks cared for
Clean glass and a spotless entrance say a lot about how a business is run, before anyone is even greeted.
More light, a better place to work
Grime cuts the daylight; clean windows lift the whole workspace and the mood in it.
The whole building covered, safely
Internal partitions, external windows and the high-level glass most cleaners avoid, handled with the right access and fully insured, so reach and safety are never your problem.
On a cycle, so it never slips
A regular schedule keeps the glass consistently clear, rather than only getting attention when it is visibly bad.
The whole building, covered. Safely.
External and high-level work is where cleaners cut corners or bow out, and it is where getting it wrong is dangerous. We reach the glass others leave, inside, outside and up top, on one schedule.



Every pane clear, inside and out.

Window & glass cleaning across South West London.
Window & glass cleaning, answered.
Do you clean external and high-level windows?
Yes. We clean internal, external and high-level glass. Reach-and-wash pole systems fed with purified water give a streak-free finish from the ground on many buildings, and we use proper access equipment, with method statements and RAMS, where the height needs it. We are fully insured for the work.
How often should office windows be cleaned?
Most commercial buildings have external windows cleaned monthly or quarterly, depending on the location and how quickly they dirty, with internal glass and partitions done on the office cleaning cycle. Ground-floor frontage and entrances usually need more frequent attention. We will recommend a sensible cycle at your walkthrough.
Do you clean internal glass partitions and screens?
Yes. Modern offices are full of glass, partitions, meeting-room screens, glazed doors, and we clean it all to a streak-free standard as part of the same service. Internal glass can be done out of hours so there is no disruption to your team during the working day.
Is your window cleaning insured and safe?
Yes. Opti Clean is fully insured, our operatives are trained, and we supply method statements and RAMS for the work, especially anything at height. Safety and proper access are built into how we quote and plan a job, so reaching the awkward glass is our responsibility, not your risk.
Can you clean the windows without disrupting us?
Usually, yes. External windows can be cleaned during the working day without getting in your way, and internal glass can be scheduled out of hours where you prefer. We agree the timing and the cycle with you up front so it fits around the building.
How much does commercial window cleaning cost?
Window cleaning is priced per site, based on the number and type of windows, the access needed and how often you want it done. We give you a fixed quote after a short walkthrough, with no surprises. Tell us about your building and we will take a look.
