I didn't rush the job,to my mind.I thought charging any more than than £70 for what I estimated a couple of hours work would be excessive.I'm not sure what I would have charged trad cos as I say,I'm not even sure it's possible.Some of the windows are so high and large I don't think a ladder would go near them.I can only assume the guy who did them trad before missed a lot of them and just did what he could.I'm positive that wfp is the right method on it,I've just obviously not caught all the dirt first time around.I don't have much experience on houses this size,so I'm still learning.
