After starting Diamond Window Cleaning in 1979 as an exclusively residential window cleaning company, my best friend, who was attending Cornell Law school in the early 80’s, sent me a multi-page pamphlet that he found on how to start your own window cleaning business. One could not just Google the information because Al Gore had not yet invented the internet, so it was a thrill to see this information show up in my mailbox. Up until that moment I was forced to learn everything by experience, which in the end turned out being the best instructor. With great anticipation I opened the pamphlet to the first page only to read these words, “Whatever you do, do not clean residential windows because your business cannot be successful doing this kind of work.” What I want you, the intelligent consumer of window cleaning, to understand is that high rise and route work window cleaning companies want your business, even though they lack entirely the skillset to do it well, because there is money to be made. High rise window cleaners and route work window cleaners have existed for many, many decades, but genuine residential window cleaners are a new and to this day a rare breed. Diamond Window Cleaning is the only window cleaner in Omaha that refuses to take commercial work…we turn it down everyday. And we do so because doing commercial window cleaning literally diminishes the skills necessary for great residential window cleaners. But if you don’t believe me, then your own negative experience of hiring commercial window cleaners will teach you the wisdom of my words. Experience really is the best instructor.
