Try Chris and Wayne. They've been cleaning our windows for the last 2 years (4 storeys)and are polite, reliable and reasonably priced. The best window cleaners I've known. (No connection, just a happy customer).
They are local to Bermondsey and clean lots of windows round here and further afield.
This is Chris' no: 07886902501.
Well I phoned Chris in the end, who was very polite, turned up on time and did a great job. He cleaned my flat roof too and also does gutter cleaning and decking! Very happy with his work and happy to recommend.
I've been looking for a window cleaner for a while for my 1st floor flat. I got one guy to do a one-off for £50 six months ago and he wasn't even able to get some of the dirt off the worst window using his extending pole system. I saw Chris's number above and got him and Wayne to do my flat. It was £20 for all the outside - 3 bedroom windows, a big balcony window and some small kitchen/bathroom/toilet windows.
They did a fantastic job, even on the disgusting window (which is due to the old man upstairs throwing bread and slops out for the pigeons and the rats below - yes really) and Chris is very friendly and easy-going. So I'd totally agree with Sierra7 and Sarah V above in recommending him.
Had a good chat with Chris after they'd finished. They go throughout London as well as SE1, doing some v high windows commercially, as well as domestic stuff - my flat is actually just in SE5 off Bethwin Road and they serve that area about once a month so you can have washing done 4 weekly or 8 weekly, which are good frequencies I think, budget-wise. Incidentally the email address is [email protected] I hope this doesn't sound like an advert, I was just so impressed!
