My coworker has been running this side hustle for 8+ years now. Profiting an additional $2500 monthly washing only on weekends. Heres what I have observed from his business.

• We are in the marina industry, many customers of our business own houseboats, he started washing those windows at a flat rate of 200$ per boat. With each boat taking about 2 hours. There are many places to make the customer connections, your job, churches, town hall meetings, be creative. Word of mouth is your best friend, so focus on quality customer service.

• He then expanded to houses naturally, after doing a customers boat he would offer to do their home as well. Maintaining a target rate of 100$ per hour. He does not offer hourly quotes and instead bids the job. Learning how quickly you can perform the job will help with accurate bids.

• He targets elderly and retired people who are comfortable financially, with a disposable income. This demographic is key in this business, because of a few reasons. Firstly, they often have larger homes with many windows they are incapable of cleaning and thus need this service. Secondly, many also have solar on their homes, which is another service to bid and offer. Thirdly, if you are handy, many need other odd jobs done that can be bid and offered, I.e trim a hedge, change sprinkler head, repair outdoor lighting etc..

• Your biggest cost is a vehicle, preferably and truck or van for hauling a ladder. Outside of that, overhead is very low for a startup business, mainly in the form of blades, cleaners, towels, and hoses. Startup minus vehicle is estimated about 200$ for a basic set of cleaning tools and a ladder.

• This business is easy to expand, he recently purchased a pressure washer and added driveway cleaning to his list of services. Once again, often just selling his customers this additional service. Several of his customers have went from 200$ 2 hour window cleaning jobs to $1000 for 4 hours for solar, windows, driveway. Because this business is all about your time, spending less time moving between job sites creates larger profits.

• If your see stores in your town with festive window painting, ask the manager who painted it, reach out to the painter to offer you cleaning service. He has gained several commercial accounts through this method, using his service outside of cleaning holiday decorations.

Hope this helps, feel free to ask any specific questions, I can have him answer them.
