To clean windows for a living, you’ll:

Need to feel comfortable when working from heights
Need a strong work ethic
Have to develop good people skills
If you feel like you tick all these boxes, then a career as a window cleaner could be just for you.

What does a window cleaner do?
A window cleaner cleans windows! Of course they do. There is, however, more than just cleaning windows in this profession. But it has to start somewhere.
Depending on the type of work you'll end up doing, jobs that you’ll also need to do include:
Mixing and preparing cleaning chemicals and detergents
Climbing ladders or using cradle and rope devices on high-rise buildings
Cleaning windows by hand
Using water fed poles to clean windows
Cleaning other relevant glass structures such as roofs and screens
Know your COSHH responsibilities and appropriately deal with substances
One of the first things to decide as a window cleaner, is the type of work you want to do.
When starting out, you'll likely only want to focus on the basics of cleaning windows. However, as you grow in confidence and experience, you may want to diversify your skillset. For example, by offering drain or gutter cleaning services as well.

What types of windows need cleaning?
When you become a window cleaner, you’ll need to decide what sector you want to focus on.
Some areas of window cleaning that you may want to target include:
Residential properties
High-rise buildings
Commercial buildings (e.g. Offices, shops, leisure centres)
Local authority buildings (e.g. Hospitals, schools, etc)
Your location will greatly affect the types of windows you clean. If you are based in a city, there will be more commercial buildings and high-rise properties with windows you can clean. That could potentially lead to more lucrative contracts.
If you’re based in a small town or rural area, as commercial properties are scarcer, you’re more likely to gain work cleaning residential property windows. However, in rural areas, homes can often be larger, leading to more (or larger) windows.
Whatever you decide to do, you’ll need some high-quality equipment to get started.
Everything you need to know about tools insurance
Not having the tools you need for a job is more than just frustrating. It can quickly put a dent in your profits if you have to delay or cancel work. Why tradespeople should consider tools insurance Stolen, lost or damaged tools can be an unfortunate fact of life for tradespeople. It can happen

What equipment does a window cleaner need?
Depending on the jobs you do, it is unlikely that you'll need to invest in lots of expensive high-tech equipment as a window cleaner. Or at least, not when you're just beginning.
To start out with private properties, the following items should be sufficient:
A lightweight but sturdy bucket
An extendable ladder
Cleaning products (e.g. Detergent, specialist window cleaning solution)
A squeegee and microfibre cloths
A window scraper
A bucket belt and other appropriate PPE
However, if you diversify and start working on high-rise buildings, you’ll also need to invest in extra safety equipment and a means of accessing higher levels.
Having the right equipment when you need it can make the job a lot easier, and could ultimately lead to a better finish. Which leads to happier customers.
