Professional window cleaning is up to the homeowner what you want is what should be bid.
Remember that true window cleaning is an art you may be able to clean windows on the inside just the same as you may be able to paint a picture, but a true artist can bring painting alive. windows are only professionally cleaned if windows are cleaned in and out by artist window cleaner.
We at Mills Enterprises Window Cleaning search and train the best window cleaners, Tammy and Richard personally train all our techs so they are truly artists.
