How often should I have my windows cleaned?

This is a matter of personal preference. Most of our clients that have requested to be on a regular maintenance program have us come either quarterly (every 3 months) or every 6 months. Although a few of our clients ask us to come in more frequently, generally you will not need to have your windows cleaned more than every three months, as the methods we use actually keep your windows cleaner for longer. In our opinion, one should look at having their windows cleaned at least twice a year.
