About Washington, DC Window and Door Replacement Companies

Like a body’s extremities, a home’s windows and doors are where much of its energy losses occur. Whether it’s cold, drafty air coming in during the winter, or air-conditioned air escaping during the summer, approximately half of a Washington, DC home’s residential energy losses are due to its windows and doors. Since many newer windows and doors are superior to older ones at minimizing energy loss, homeowners often decide to replace them to decrease their energy bills. However, energy efficiency isn’t the only good reason to consider replacing your windows and doors. Besides lower energy bills, new windows and doors can actually make your home more secure. Since windows and doors become easier to force open after decades of use, replacing them can provide the safety-minded DC homeowner with an increased sense of security.

The three most common types of windows are wood, vinyl, and composite. Wood windows are more traditional and come in a variety of styles and colors; however, they do require a bit of maintenance to keep the wood from deteriorating. Vinyl windows are essentially maintenance free, provide excellent insulation, and also come in a variety of styles and colors. Composite windows combine the best of both wood and vinyl. Made from both wood and plastic or fiberglass, composite windows look like wood, but require almost no maintenance.

Whatever your reasons for replacing your windows and doors, a DC Best Pick™ window and door company can help you find the material and style that’s best for you.
