Factors Affecting the Cost
When it comes to commercial window cleaning, there are a variety of factors that can impact the cost. By taking the time to understand these factors, you can better understand what to expect and make more informed decisions about your window cleaning needs.
Building Size & Number of Windows
Regarding commercial window cleaning, your size and type of building can significantly affect the cost. For larger buildings with numerous windows, additional time, equipment, and manpower may be required, resulting in a higher expense.
Suppose your building has unique architectural features or hard-to-reach windows, such as those at great heights or in challenging locations. In that case, specialised equipment or techniques such as cherry picker window cleaning may be necessary, adding to the overall cost.
In short, the job’s complexity can impact the price, so it’s essential to consider these factors when considering professional window cleaning services for your commercial building.
Frequency of cleaning (One-Off vs. Contract)
The frequency of your window cleaning needs can impact the overall cost. Depending on the business’s preference, some opt for a routine cleaning schedule, such as weekly, monthly, or quarterly, while others may only require one-time cleanings or seasonal touch-ups.
Consistent, scheduled cleanings can ultimately lead to cost savings, as the windows are easier to maintain and require less time and effort to clean.
Type of Glass or Facade
The state of your windows before window cleaning can have an impact on the final cost. In cases where the windows haven’t been cleaned in a while, it might take extra effort to get rid of the accumulated dirt, grime, or mineral deposits.
As a result, the cleaning service cost may increase to accommodate the additional labour required for a thorough cleaning.
Location within London
Where your building sits in the city can affect the overall cost. Central London locations such as the City, Westminster, Mayfair, and Canary Wharf typically command higher rates due to increased travel time, parking restrictions, congestion charges, and the logistical complexity of working in busy areas. Buildings in outer boroughs are generally priced lower as a result.
Height and Access Method
When it comes to windows, accessibility is vital. If your windows are easily within reach of the ground or can be accessed with standard equipment, you can expect a lower cost.
But if your windows require specialised equipment like MEWPs, rope access equipment, or additional safety measures, you can expect the price to increase. So, it’s essential to consider the accessibility of your windows when planning for your project.
What Cleaning Method Will Be Used?
The method your window cleaner uses has a direct impact on the price. Different building heights, facade types, and access constraints will determine which approach is required.
Reach and Wash (water-fed pole) is the most common and cost-effective method for low-to-mid-rise buildings. A telescopic pole fed with purified water cleans and rinses windows without the need for ladders or scaffolding.Â
Abseiling / rope access is used for high-rise buildings or facades where access equipment can’t reach. Operatives work from the roof using ropes and harnesses. It requires specialist training and equipment, so carries a higher cost, but is often the only viable option for tall commercial buildings.
MEWP / cherry picker is a Mobile Elevated Work Platform provides a stable working platform for mid-to-high-rise buildings. Ideal where rope access isn’t suitable and the surrounding area can accommodate the equipment. Costs reflect equipment hire on top of labour.
How Are Commercial Window Cleaners Priced?
By the Hour
Hourly rates typically range from £15 to £25 per hour in London. This pricing model works best for one-off cleans, smaller offices, or jobs where the scope is difficult to estimate in advance.
By Area (Per SQM)
For larger buildings, cleaners will often price by the area being cleaned, typically £1 to £3 per square metre. This makes budgeting more predictable and is the standard approach for ongoing contracts on bigger commercial properties.
Fixed Contract
A fixed monthly or quarterly contract locks in a set price for regular scheduled cleans. This is the most cost-effective option long-term, as consistent maintenance keeps windows in better condition and reduces the labour involved in each visit.
How to Get the Best Value?
- Set up a regular cleaning schedule. Consistent cleans prevent dirt and grime from building up, meaning less effort per visit and lower costs over time.
- Get multiple quotes. Prices vary between providers, always request at least two or three quotes and ask for a full breakdown of what’s included.
- Opt for a fixed contract. Regular contract customers typically receive better rates than one-off bookings, and it removes the admin of arranging cleans each time.
- Prioritise high-visibility areas first. If budget is tight, focus cleaning on customer-facing windows and entrances to maintain a professional appearance without cleaning the entire building every visit.
- Book during quieter periods. Some providers offer better rates during off-peak months, January to March tends to be slower in the industry, making it a good time to negotiate.
- Use preventive measures. Window films and protective coatings can slow the build-up of dirt and extend the time between professional cleans.
