A window cleaning business sounds like a good idea, unless you consider the fact that most people will want the full house cleaned, not just the windows. Most of the already have cleaners who clean the whole room including windows.

Some of the materials you will need for this business include detergents, wash clothes, brushes and basins. You should sit down and write a business plan which will include all the things you need for providing cleaning services.

You can market yourself online through different social media accounts. You could also print posters and place them in different spots in town or in that area that you see there is good market for your business.
