Helen, I've a few accounts in the estate that is last on the left as you head towards Caldicot, God knows what the name of the estate is though!
I'm picking them up this week, I'll take note of the name of the estate.
Dave, on a small house there won't be a lot of difference between WFP and trad, unless of course it is either leaded or Georgian.
The larger the account the bigger the time differential, I have some 3 storey accounts that took up to 5 hours trad, WFP = one and a half hours.
Ignore WFP until you have built up a decent sized round, but have your customers prepared from day one that you will most probably be changing your system and method once you are well established.
Have a minimum price of £8.00 if you like, then adjust it by a £1.00 per window after that.
In other words, if a customer only has 3 or 4 windows, you STILL charge your minimum!
The temptation to go in cheap to initially build up your round is incredibly hard to resist because you really need the work...do your best to resist that temptation!!
