"Andrea was great to work with and she wasn't pushy like a few others I got quotes from. She knew the product and was able to answer questions. Brett and Aurelio was great when they came to install the windows. They explained how the process was going to go and how long it should take. Great group of people and would highly recommend them."

Windows FAQs, answered by experts

There are several ways to reduce noise coming through your windows. You can seal gaps around the window frames with acoustic caulk or fresh weatherstripping to reduce noise and air leaks. Installing sound-dampening curtains, thick blinds, or shades can also help deaden sound vibrations. For an additional interior barrier, consider installing an acrylic or plexiglass sheet inside the window, which stifles sound while still allowing for outdoor views. Another strategy is to add external barriers, like dense shrubbery or a sturdy fence, to block neighborhood noises. If these methods are not effective enough, it might be time to install new noise-canceling windows.

Bay and bow windows can increase the value of a home. These window styles not only enhance a home's aesthetic appeal by adding architectural interest and increasing natural light but also create additional interior space for seating or decorative purposes. The added functionality and visual appeal can make a home more attractive to potential buyers, potentially leading to a higher resale value. However, the impact on home value depends on various factors, including the overall condition of the home, local real estate market trends, and the quality of the window installation.

Yes, including the frame instead of just referring to the glass opening for window dimensions is the standard. However, some manufacturers may refer to the rough opening instead of the framed opening when listing sizes. Always confirm which measurement a manufacturer is using before ordering windows.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.
