The service that I use to clean my windows and outdoor lights is stupendous and reasonable. Today, they cleaned the outside of 10 double hung windows, front door, 8' patio door plus transom, a semicircular window and 4 outdoor lights for $65. It took the crew of three a little less than an hour.
In the spring, I have them also clean the insides of the doors and windows. I found them thanks to Carol C
