Many customers and curious people ask about rain after window cleaning. I reply with two answers. One, that is not the rain that gets the windows dirty, it’s what is in the rain. Therefore, if your house has a lot of dirt on it, then it will show up on your windows more frequently than if your house did not. Pressure washing prolongs the window cleaning for this reason. Also, dirt from screens gets in rain easier, so this is one of the reasons we wash screens first. My second reply is, if you haven’t cleaned your windows in awhile, your windows will still look cleaner than before the rain. Regular cleanings prolong the visibility through your windows. If it does happen to rain during day of service, I am reasonable and would be willing to offer a discount.
