I analize to see how much risk there is to be taken to do a freebie. It may not even be something necessary. After all who knows better what should be done than a pro. In the event the homeowner has an opinion or a need, that's different...like trimming the tree off the roof or clear of the satelite signal etc. In other words, I'll do it as long as it is not something that doesn't need to be done or wouldn't make a differnce any ways. I'm not gonna climb again to do something that satisfyies more an obsession than a need or a thechnical correction. Often people may also try to modiffy the end product. I have high satandards and so by explainning, therilly, what will be done (through vissuallizin the endproduct),and conveying it to the costumer accurately, and ofcourse making sure he undrestands, then I feel that that is the best way to avoid a missunderstanding at the end.By leaving blurry areas to the deal the costumer is morelikely to include more work in the work order. Being service oriented means a lot of things, however, free dangerous work or the use of equipment or labor that could run for as much as several hundreds of dollars an hour, I don't believe are the samething. Be punctual, polite, proffessional, sensitive to their needs,But charge for your time. Any thing that takes more than 5 min. I charge. more than 5 feet up. I charge. more that five times the weight of my dog. I charge. As long as they get a good value for their money or/and exxellent quality they are't going to complaint.
