Hi Ryan
Exactly what CleanGlassuk said charge hi price and see what the customer say.
I live in Brighton and if you e mail me the photos, maybe I can help you to put a price for it., my e mail is:
info@pccom.co.uk.
I had one similar situation on Monday where a lady called me and she had 5 windows on 5th floor which was situated in centre of hove next to church Road.
Where you have to stand middle of the road to clean it and have to extend the pole up to 60ft. i told her 1st we have to do it on early Sunday morning due to the traffic and because is so high and hasn’t been cleaned for past 2 years, she is looking to pay £70.00
I hope this will help.
Regards,
Bosh
