"The owner/operator Brad was very professional. He helped us pick out a new storm door that looked really great with the exterior. The install went very smooth and fast without any issues. After the job was completed zero waste was left behind. Overall we are very happy. We highly recommend this company."

Windows questions, answered by experts

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

No, not every window has movable sashes. Many fixed or stationary windows that were intended only to provide views and sunlight still have inoperable sashes that allow them to match the rest of the windows in a home. These are called sash-set fixed windows. They are created by glazing a window into a sash that is secured to a frame.

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.

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

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.
