I currently have a window cleaning account that needs to be done once a week. It is about 1050 square feet; what is a reasonable price to charge per square foot?


You have got to determine this for yourself. The key question is: How long does it take you to clean this window? Then, How much do you need to earn per hour to pay the bills?
The ISSA Cleaning Times booklet says you can do 100 sq. ft. in about 10 minutes with a brush and squeegee. That seems slow to me since that represents one side of a 10’ x10’ glass pane. Maybe it refers to doing both sides.
What happens if you move to an 18” strip washer and a 36” squeegee? Can you improve on those times? I think you could cut the time in half, if not more.
Pick a window similar to that one you are doing weekly and clean it, timing your effort. Now you know how long it takes. Then, decide what you can do in terms of equipment to speed the operation. Is the inside done also? Is it accessible?
Most window washers are going to price by the job, not by the sq. ft., but it wouldn’t hurt to learn your production rate for various settings.
