United Window & Door

United Window & Door offers both replacement windows and new construction windows, as well as both hinged & sliding patio doors.

When someone complains about a room being too hot or too cold, they often blame the heating or air conditioning system. But windows, often overlooked, also play an important role in comfort in buildings and can account for 30% to 40% of energy costs. United Window & Door offers a wide variety of replacement options that will help make your home more comfortable and more energy-efficient.

Did you know: United Window & Door was chosen to supply and install their products for ABC TV's "Extreme Makeover: Home Edition" for the Luther family in Port Deposit, Maryland! See the video here.

United's new construction windows provide excellent thermal properties and superior sound absorbency to meet today's national energy saving requirements. Fusion welded construction virtually eliminates air and water infiltration while assuring overall durability.

United Window & Door also offers high quality sliding, swinging and french style patio doors with energy efficient options for both new construction and replacement applications.
