Whether you are looking for durability and maintenance free aspects of vinyl, the strength and paintable flexibility of fiberglass, or the warmth & beauty of wood will be entirely dependent on your remodeling goals and your pocketbook.

No matter what you choose, getting the right installation will be the key to long lasting satisfaction with your window decision. Medallion Security Doors & Windows has been installing new and replacement windows in the DC Metropolitan area for over 25 years.
