"Had a problem with a pet tearing my screens. Jay gave me his expert opinion and recommended a pet proof screen. He installed that in the back and a regular screen for my front door. They both look great. So far so good with the pet screen! ?"

Windows questions, answered by experts

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

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, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.
