I don't use a ladder to do shops, so no I won't have it on a pavement.
You'll still have a trip hazard.
Prices may come down, but wfp users want more money for the job usually.
Oh, and how can wfp do windows above flat roofs, over gates, open windows, cracked leaded, etc...etc...
The only ones I don't do are above conservatories, and the customer's fine about that.
There's loads of windows I couldn't access with wfp.
Why can't blinkered wfp uses just accept that?
It's cost you silly money, that's why.

Not directing this personally at you Trev, it's the forum in general.
