dr windows you are shooting yourself in the foot mate, so what if they havent done a million years plodding in the rain cleaning houses, the guys are there to get you a certificate based on the health and safety side of cleaning THE COURSE DOES NOT TEACH YOU HOW TO SQUEEGEE A WINDOW its about cleaning safely at height
If you dont wanna do it fine, just dont go knockinh it, you end up sounding like the plonker my friend, and dont always go on EXPERIENCE, i know lots of old cleaners, but it doesnt mean they are professional, insured , safe or anything else, just they have been picking up bad habits and doing things wrong for a long time, shame they dont do an nvq and learn the right way

ANy serious window cleaning business needs eventually to get some PROOF of competence
otherwise serious clients wont take a second look
not talking council houses here, but big jobs!
