O/T - Window cleaner in Norwich

[phn]

Can anyone recommend a good window cleaner in the Norwich area?

It seems most window cleaners these days use a de-ionised water and a long brush and then charge you a huge amount for what was 3 mins work - the results are usually poor as well.

I'm looking for someone who will actually clean the windows in the old fashioned way (ie up a ladder with a squeegee) and do a decent job.

Any recommendations?

Thanks!
