At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

Windows questions, answered by experts

DIY is possible with proper tools and knowledge. Professional installation ensures a proper seal and energy efficiency.

During hurricanes or other major storms, high winds can cause objects and debris to fly through the air, which can break your windows. Depending on how strong the storm is, the winds themselves may be strong enough to break your windows, too. Investing in storm windows or hurricane shutters can help protect you against potential window breakage.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

If your winter looks like heavy snow, freezing rain, or frigid temperatures, taking your screens out for the season can be a great way to avoid mesh damage or bent frames. Ice can build up and put pressure on the screen, especially in older or aluminum frames. Removing them also lets in more natural light during those shorter winter days and makes it easier to keep your windows clean. In warmer climates, it’s less about protection and more about preference. Some homeowners like the clearer view while others leave them in for convenience. Either way works—it depends on your setup and what you value more.

Options include interior, exterior, and double-pane storm windows. Choose based on needs and preferences.
