The whole world is brighter since Joe thoroughly cleaned the windows and the screens. I am brand new to this house from Maryland and who knew I could see a pond, red winged blackbirds and a storm coming. Yoo hoo. Thanks, Joe. I can see again. Anna

Wow. This guy shows up and had the entire 5,000+ sq. Ft house power washed and with streak free window cleaning before he estimated. On time. Got started right away. The price was the best after shopping around and I will be calling him next year for another power wash and window cleaning.

Not only did Joe make the view sparkle from inside the house, he arrived promptly and worked so efficiently for us. He was even willing to tackle a bit of power washing for us at the end of a long day. Thanks Joe...we will definitely call the Window Gang again!!

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We have standardized guidelines for our pricing. We like to come out to your home and give a free estimate. We will measure your home/building and make every effort to work within your proposed budget and timeline.
What is your typical process for working with a new customer?
We offer free estimates and like to meet potential customers at their home/business so we can discuss the size and scope of their project.
What education and/or training do you have that relates to your work?
I have been working for Window Gang for 15 years. I started out as a trainee and worked my way up to a crew leader. I was then given the opportunity to manage and run Northern Virginia and eventually to own my own franchise. We are provided with extensive training and guidance every step of the way.
