Window Replacement

Windows are one of the most versatile elements of a home. Not only do they add natural light to any room, but they also add ventilation and fresh air. In addition, your windows contribute to your home’s energy efficiency as well as its overall curb appeal. With all of that being said, it’s important to have quality windows in your home and if you’re looking for replacement windows, our home improvement company can help.

At PJ Fitzpatrick, we’re always looking for ways to help homeowners go green and save on their energy bills. Many people aren’t aware of how much windows can affect their home’s internal temperature and if your windows are old, outdated, or just poorly made, you could be losing up to 35% of your home’s heat through your windows. Drafty windows let cold air into your home during the winter and hot air into your home during the summer, which means your HVAC system has to work harder than it should to keep your home at the optimal temperature. However, with quality-made windows, you can improve your home’s energy efficiency and reduce your monthly energy bills.

A Variety of Styles

One of the best things about windows is the wide variety of styles that they’re available in. From a classic double-hung style to the bold look of a bow window to a special custom shape, you can choose a window that not only fits your budget but fits your taste. In addition, each style of window can add a different look to your home, making them an artful aspect for both your interior and exterior.

Our window installation experts know the ins and outs of all types of windows, so if you’re unsure which is the best option for your home, we can gladly help you decide.
