First impressions matter more than most businesses budget for. A shopfront with streaked glass or a reception window covered in road grime tells customers something about the business before anyone’s said a word. Trendline provides commercial window cleaning for offices, retail units, restaurants, and managed properties across Croydon and the wider South East, using the same ground-based Reach & Wash system that’s cleaned windows for over 2,000 households since we launched in Croydon in 2021.
We work with local businesses, not facilities-management portfolios. That means no call centre, no account manager three steps removed from the person doing the work, and a team that actually knows your premises rather than treating it as one line on a spreadsheet.
Who We Clean Windows For: Shops, Offices, and Local Businesses
Our system uses purified water pumped up telescopic poles fitted with soft brush heads, cleaning glass, frames, and sills from the ground. No ladders on your premises, no scaffolding blocking an entrance, and no working-at-height risk for anyone involved. That makes it well suited to the kind of premises most local businesses actually occupy: retail units, standard office buildings, and smaller commercial properties where scaffolding would be impractical and expensive for a routine clean.
This isn’t a fit for every building. If your premises needs rope access or a cherry picker to reach the glass, that’s outside what our system is built for, and we’d rather say so upfront than take on a job we can’t do properly. For the majority of shops, offices, restaurants, and small commercial buildings across our coverage area, though, ground-based reach and wash is faster to arrange, cheaper to run, and just as thorough.
What Does Office Window Cleaning Involve?
How Do We Avoid Disrupting Your Working Day?
Office windows need to look sharp during the hours people are actually looking at them, which usually means the clean itself needs to happen either before the working day starts or without disrupting whoever’s inside. We work around your actual working pattern rather than asking staff to work around ours, and there’s no need to clear a meeting room or rope off a reception area while the work’s underway. Because everything is done from the ground with a pole, there’s no equipment brought inside the building and no access required to individual offices.
Multi-Storey and Single-Storey Offices
A single-storey office and a multi-storey building are cleaned the same way, just with a longer pole. The telescopic reach means upper floors get the same attention as ground-floor glass, so there’s no separate arrangement needed for the windows that are harder to see from the pavement. Reception glazing, meeting room windows, and any glass partitions visible from outside are all included as part of the same visit.
Can You Clean Shopfronts and Restaurant Windows?
Shopfronts and Signage Glass
A shopfront window is effectively part of the shop, since passers-by judge what’s inside before they’ve stepped through the door. Shopfront glass, signage panels, and any street-facing windows are cleaned together so the whole frontage looks consistent rather than just the main pane getting attention. A clean window next to a grimy signage panel looks half-finished, so we treat the whole frontage as one job rather than billing separately for each pane.
Restaurants and Cafés
For restaurants and cafés, the window is doing double duty as both a barrier and an advertisement, since most passing trade decides whether to come in based on what they can see from outside. A clean, streak-free window makes the inside look brighter and more inviting than one with smears from the last few weeks of condensation and finger marks. Because pure water leaves no chemical residue, there’s no concern about anything transferring onto surfaces near food preparation or seating areas close to the glass.
Can You Work Around Our Trading Hours and Provide RAMS?
Working Around Your Trading Hours
A window clean that disrupts customers or staff isn’t much of a win, even if the glass ends up spotless. We can schedule around early mornings, before a shop opens, evenings after close, or whatever gap in the day causes the least disruption. For retail and hospitality premises, a clean that happens while the shutters are still down is usually worth more than one squeezed in during peak trading hours. Regular commercial customers are typically set up on the same 4-weekly or 8-weekly rounds we run for residential properties, so scheduling becomes a standing arrangement rather than a fresh conversation every time.
Insurance, RAMS, and Compliance
Commercial and public-sector premises generally need more than a verbal assurance that a contractor is insured. Trendline operates as a fully insured limited company, and documentation such as insurance certificates or a risk assessment and method statement (RAMS) can be provided ahead of any work starting. This is particularly relevant for schools, managed buildings, or any site with its own contractor sign-off process. If your premises requires DBS-checked operatives or a specific compliance step before work begins, let us know at the quote stage so the paperwork is sorted before the job, not on the day. We also invoice management companies directly for multi-occupancy and managed properties, so landlords and agents get one point of contact rather than chasing individual tenants.
How Much Does Commercial Window Cleaning Cost?
One-Off and Contract Cleans
Some commercial customers just want a single clean, perhaps ahead of an event, a client visit, or after building work nearby has left windows dusty. Others prefer a standing contract on a set schedule so it’s one less thing to think about. Both are priced differently: a one-off reflects the condition of the glass on the day, while a contract rate is worked out once and stays consistent for the length of the arrangement.
What Affects the Price
Commercial quotes depend on the number of windows, the size and layout of the building, and how often you’d like the round to run. A single shopfront and a two-storey office building aren’t priced the same way, and neither should be quoted from a generic list. Send us a few details about the premises and we’ll come back with a clear, no-obligation quote rather than a rough estimate that changes once we’ve actually seen the site.
Frequently Asked Questions
Do you work outside normal business hours?
Yes. Early mornings, evenings, and other out-of-hours slots can be arranged, particularly for retail and hospitality premises that need the work done before or after trading hours.
Are you insured for commercial premises?
Yes, Trendline operates as a fully insured limited company. Insurance documentation can be provided ahead of work starting.
Can you provide a RAMS document?
Yes, a risk assessment and method statement can be arranged for sites that require one, such as schools or managed buildings with their own contractor requirements.
Do you work with schools or care settings?
Yes. If DBS-checked operatives are needed for your setting, let us know when you enquire so we can confirm what's available before booking.
How is commercial pricing worked out?
Pricing is based on the number of windows, the building's layout, and how often you'd like the round to run. We quote based on the actual premises rather than a flat rate.
Can you invoice our management company directly?
Yes, this is common for managed buildings and multi-occupancy properties, and we're happy to set up direct invoicing rather than billing individual tenants.
What if our building needs more than ground-based access?
If a premises needs rope access or a cherry picker, that's outside what our reach and wash system is designed for, and we'll tell you that during the quote rather than after the job's underway.
How often should commercial windows be cleaned?
Street-facing premises exposed to traffic and pedestrian handprints often suit a 4-weekly round, while office buildings set back from the road can usually go 8-weekly. We're happy to start with whichever makes sense and adjust from there.
