Hi all, new to the forum. Have been window cleaning by pole system for about 2 years now. Started up a new business with my father in law. He bought a new van, hot water system, a couple of new rounds of other window cleaners. We have started a new round recently (in January) some customers have called and said they don’t want us to clean their windows anymore (no reason was given even after we asked why). Is this normal? The person we bought the round off of was their window cleaner for 20 years. I haven’t been rushing the jobs or cleaning any different to what I usually do, is this something to be wary of? I thought some customers would leave because people don’t like change usually which is understandable but my father in law is very precise and can have a bit of OCD so he wants everything to be 100% and not have any complaints ever. Any advice would be very appreciated thank you.
