Absolutely a big NAY!!!

If a window cleaner came knocking on my door asking me to commit to a contract I would genuinely feel that he was trying to trap me. It sounds so impersonal and unfriendly.

I have a very professional image and a very good relationship with my customers. I try to be flexible and as helpful as possible. None of them ever take the michael and they appreciate my service, but occasionally I have had a customer asking me to stop for the winter. I always say 'Certainly, I will cancel the service and IF i have a vancany in the spring I will come over and requote for you'  - Because I have such a good reputation and they know how busy I am they always say 'oh, just keep cleaning them'

That's excellent advice

Wish I'd thought of it years ago.

You would still need to do it tactfully, anyone who's not bothered about having it done in the winter wouldn't need much excuse to say "OK then, I'll find someone else next spring"
