I changed over, or rather added WFP as a tool 5 months ago.
My reason was simply safety. I wasn't looking for any other benefit. I do all first floor upwards with WFP and all of the property if it's georgian ( with decent paintwork) and leaded.
Haven't lost one customer due to the change and am now at least 30% faster. And in my opinion 100% safer. Like Dia says its like any other tool. Use it badly, try to cut corners etc and you will get bad results. Use it correctly and the results are excellent.
I was talking a few days ago to another WC in this area who made the change over 3 years ago. He hasn't looked back since and makes VERY good money. Again like Dia says he has cleaned up (scuse the pun
) on good commercial work around here.
No way would I go back to ladders for all work. I still use them for access but that's about it.
Oh yes.. and I use my creation.. the Pure Freedom system. Well.. I looked around and decided I needed something specifically designed to do the job a regular window cleaner does.
