I know many shiners who have bought from pat dudly smith.
It does sound expensive at 3 cleans for canvassed work but he replaces anything without asking questions and has great aftercare!
The man has made millions from building rounds over the last 20 years.
If looking to start into the window cleaning game going through pds is a safer move than many.
I did some canvassing for him about 10 years ago for just 1 time and because it was in rough areas he wouldnt take the work and said he wouldnt put that on somebody which at the time realy annoyed me but looking back now it shows he is in it for the long and to not rip people off... A plus side the work he didnt pay me for that i canvassed is what started me off many years ago and turned out to be good work even though i did get shot of it as was in north london.
If you know what your doing go and get the work yourself,, if not then the likes of pds will put you on the right track.
