"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

Windows FAQs, answered by experts

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

If you don't have hurricane shutters or impact-resistant windows, boarding up windows before a hurricane is worth it. According to the Federal Alliance for Safe Homes, protection is essential for all your home's entry points, including windows, doors, skylights, and garage doors.  

When windows break, wind enters your home, creating enough pressure that could cause the weakest part of your to rupture. Often, the weakest part is the roof, which can "pop" off of a home in a hurricane. The simple act of boarding up your windows can protect the structural integrity of your house.

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.

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.
