Just turn up to peoples houses unannounced with all you gear, raring to go

You can laugh, but I did just this by pure mistake when I knocked on the wrong door with a wand and buckets in my hand.... The lady opened the door and said "Hello, come in.....!"
"I said "Thank you Mrs Johnson!
"I'm not Mrs Johnson, she lives next door!"

I apologised and asked if she wanted a quote to which she replied "I've got wooden flooring!"
You may get lucky with this approach
