We have all turned up to that paranoid customer that is convinced that their gutters need clearing and when you get up the ladder this is obviously not the case as they are totally empty. By this point you have already agreed a price with the customer so do you: A: Do 10 minutes work, pack up collect the money and say thank you? B: Take the hit and say 'cant charge you I ain't done nothing' C: LOOK busy for an hour or two then pack up and collect? Well whichever you chose only B is the correct answer but the issue with that is you are out of pocket for time and fuel. Now I am adding the new service to my resume, 'Gutter Survey' Plenty of us now have a GoPro or similar camera that can attach to a pole to video the inside of a gutter and see whats what so I will be offering 'The Survey' for just £9.99 Instead of pricing guttering per job in future I will give an hourly rate and an estimate as to how long the job should take however prior to any of that I will come out and do a full video survey and written report for £9.99 madam, should the gutters need any further attention this £9.99 will be deducted from the overall bill at the end of the job. I think there's some legs to that.
