£100's not really on a standard 3 bed house, but you can charge more than that of a guy with a ladder and bucket.
And before someone thinks of jumping on my back. Think about the other call out charges from other companies and what they use.
1 is a drain jetting company £100 min charge takes 5 mins but they have the professional tools, my home use pressure washer 10 mins cost me £60.
it is perceived value that sells.
Now on guttering, man and ladder charges lets say £25 takes 15 mins using ladder and bucket, down he comes from lader with bucket in hand, knocks door £25 please madam, shes there adding up in her head this guy is making £100 an hour my windows only take 15 and he charges me £7. Her end thought i am getting done here. Not everone is like this but any are.
Gutter vac cleaner charges £50 takes 15 mins unloads equipment that customer sees, shows dvd video proof gutter cleared. knocks door when finished £50 please madam. she pays and feel happy...
Same job, difference equipment, different price.
This is what I have found doing this job both ways.
I do not charge any of the prices above, they are an example. each job is different!
