If you live where there is snow then residential window cleaning comes to a halt. However if your looking for a consistent cash flow for winter then through out all the summer months you should be building up your commercial store front work. They do not pay high dollar but I look at it like mowing lawns, you don't get rich off one, but if you get a route you can do okay. Face to face contact with the business owners is the best marketing you can do. Constantly be in front of them. Send christmas cards to them even if their not your customer. When their bucket bob leaves guess who they will think of

Now the winter and snowfall covers all the windows. So windows cleaning is necessary in the winter. Marketing is necessary to promote the services.

Have you tried giving parallel work to window cleaning as plowing snow around peoples houses, it should provide some bit of work and the people usually request your other service too especially if you offer them a discount because you were plowing snow. This tactic should be able to work if you advertise your snow plowing business a bit more too

Sometimes I'll just stop working in the winter and just wait for new clients to call me, I havent really found an optimal solution so thank you all for advices

There are a ton of ways to do that, actually it might be even more ways than during the summer if you're trying to be creative, you can just open up another parallel business to the first one and advertise your business whenever you finish a job

I'd suggest you not doing that, it might be a bit costly, I noticed you're not too serious about this but it can give you a lot of money

then what should I do, its a bit too much for me to just leave like that

I've seen you do multiple jobs so I'm guessing it might be fine to combine them, advertise your business on the other one and try to see how it goes

Yep that might be a good idea that's what I was doing when I was starting up my business but I've focused on window cleaning much more now so good luck with that

I didn't really think of combining them so that sounds like a good idea to me. Thanks for the advices guys I'll keep you updated
