The Window Center wants to treat each customer in such a memorable way that when the work is complete, our customers will tell someone else how great it was.

On a personal note, the staff at Allied treat you the way they wish to be treated as customers. Three sons-in-law and one daughter of the founder believe in old-fashioned courtesy, character, and honesty. Trained in the values & philosophy of the founder, Obren Dean, we believe in living up to his ideals of integrity, fairness, and human kindness.

The Window Center, a family owned and operated company, was established to provide top quality windows and siding at affordable prices. Having been in business for over 40 years, The Window Center has installed thousands of windows all over Northern Virginia. We have the products and experience to make your home look beautiful.
