anyone changing over to wfp should read this post to help them make a more realistic decission, this will happen, why would the customer want their walls/sills left dripping or her decking/patio left wet through etc, etc. when she could have them done trad without any of this oh, & her windows be left dry too.
Too many people on this forum only blart on about the benefits of wfp, but there are many down-sides too.
Any potential wfp converter should never assume its the be all & end all of window cleaning, its not.
I'm wfp + trad (before the barrage of abuse begins)
