Why bother with sign writing if you have plenty of work?
ive had sign written vans for 7 or 8 years now dave.id hate not having it signed.it brings in work all year round.yes i have plenty of work for me but we all lose some here and there for whatever reason(moving,dying,cant afford it,etc).
i recently lost a £70 job to another window cleaning company purely because they do pressure washing,roof cleaning,gutters as well as window cleaning.i have picked up jobs they used to do as well over the last few years so it balances out.
its not just the extra work that a sign written van brings in but it looks more professional IMO and makes you stand out from the rest.keeping the van clean and tidy helps too even if its just my attitude to window cleaning.
i know loads of window cleaners who work from scruffy, dirty, unsigned vans and they seem happy enough but its not for me.(it was many years ago but i prefer to have a crisp,clean cut image portrayed to customers these days)
