I have my windows cleaned professionally. I found the guy when I saw him cleaning shop windows in the market place and asked if he did private premises.

I'm not located in the UK, but I know that there are many companies which can do that for you. Even our company started offering high-rise window cleaning for tall buildings, because the demand for such services is growing bigger and bigger each day. Just browse online or look through some classifieds in your neighbourhood, and I'm sure you'll find something.

In UK, Cleaning Please has such a service. I used them for window cleaning and they brought back the light into my rooms!
