Montgomery County's Best Window Cleaning Company
Hi, I’m Seth Fensterstock. I founded Windows Only in 1998 in my hometown of Bethesda, Maryland. After working for several years for other window cleaning companies, I found myself dissatisfied with the way those businesses sacrificed quality and safety to make a buck. I decided to try going into business for myself. With those early experiences in mind, I have built Windows Only around the principles of professionalism, safety, superior workmanship and outstanding customer service.
Starting as a small, one-man operation focusing only on window cleaning, I have grown Windows Only into a successful business that today offers many services to Montgomery County.
