Our window cleaning services
Every programme is planned around your building, your access and how often the glazing needs attention.
- ✧Commercial Window Cleaning. Scheduled external and internal window cleaning for offices, retail units and commercial frontages, keeping glazing consistently clear on a cycle that suits your building.
- ✧Residential Block Window Cleaning. Communal and external glazing cleaned for managed residential blocks and estates, planned with managing agents around resident access and presentation standards.
- ✧High-Access Window Cleaning. High-rise and difficult-access glazing cleaned using reach-and-wash, cradle, rope-access or MEWP methods, with working at height planned around a site-specific risk assessment.
Every clean is scheduled, tracked and quality-checked through our CleanManager platform, with photographic evidence and completion reporting available on request.
DBS-checked operatives. COSHH compliant. Method statements and RAMS provided where required.
How We Work
Every building is different, so we plan each window cleaning programme around your access, your frequency and the safest method for the glazing.
01. Enquiry and Assessment
We start with a conversation about the building, the number and type of windows and how often you need them cleaned. For larger or higher-access sites we carry out a site visit to assess access and method.
02. Planning and Preparation
We confirm the method, the frequency and the access equipment, and produce site-specific RAMS for working at height where required, so everything is in place before we arrive.
03. Delivery
Our work is led on site by an experienced operative who manages access and method throughout. We clean to a smear-free finish and work around your opening hours and footfall.
04. Final Check and Sign-Off
Before we leave, we check the finish across all elevations. Recurring programmes are tracked and logged so standards stay consistent visit after visit.
