If you like the idea of owning your own window cleaning company Dublin has the population to support such a venture. A lot of your business is going to come from word of mouth, and you’ll be competing against already established cleaning companies. However, it can still be profitable, especially if you focus on both residential and commercial clients. Getting your foot in the door, so to speak, is possibly the hardest part of running your own window cleaning business, and it will mean promoting yourself as much as possible, not only online, but by handing out leaflets, posting in local shops and anything else you can think of. It won’t take too much money upfront to clean windows, although you’ll need cleaning supplies and equipment, and of course reliable transportation. It can certainly be a satisfying alternative to the typical 9 to 5 job.
