i paid £8000 for £2500 18 months ago the only thing with pds is he guarantees his work so if you lost say 20% which i did he will give you 20% more work i did have to wait a week or so to get this not to bad the other thing is when he gets the work so he does not lose the customer he gets his lads to clean the windows these are the ones i lost as they were so unhappy with the clean from them and sometime he says to them to pay for 3 or 4 cleans in advanced and i also got stung with this
as i had to clean them for free so i just said i had lost more than i had to make this up as you do pay a lot of hard earned cash but saying that he is a nice guy and is helpful with after sales...go for it hope this helps stu
