Got a phone call the other day from the gardener of a house i do , saying can
i stop using wfp and do them trad

Reason wfp damaging paint and putty

I found out they've just had windows painted and repaired,and the guilty windows are south facing.
I dont want to do them trad because there Georgian ,and a lot of windows are hard to get to.
This is a big house worth £250 every 3 months not quite sure what to do.
