"I had custom double pane tinted windows replaced due to condensation forming in the original windows. The whole project went very well from initial appointment when they measured the windows and later provided a quote, to the installation. Installers took their time and did excellent work. I will call them again if I need windows replaced."

"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.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

In most cases, you should get your windows cleaned one to two times annually, although you might want to complete this task more often if you live in an area with heavy pollen or heavy rain or snowfall that soils your windows. It’s also a good idea to hire a professional window cleaning service if you’re listing your property, as sparkling windows will make a big difference in terms of curb appeal and, potentially, your home’s value.

Look for stickers at the top or inside of the frame, like in the tracks when the window is open. Some brands also stamp their name onto the frame itself or place it between the panes of glass, although this is less common. If you can’t find the info on the window itself, consider asking your neighbors or HOA.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.
