"Peter and his team did a wonderful job of presenting the product, discussing the job, giving a fair price, constant communication, as well as a wonderful install process. We would absolutely recommend this company for vinyl siding replacement and will be calling them for windows in the future."

"Sheldon and his crew did a fantastic job installing our staircase banister and making an adjustment to the panel to our bay window shutters. We had new windows installed and despite the installers assurance that the measurements would remain the same the bay window paneling came out smaller than expected. This was a problem because we also ordered shutters and blinds and we told the window installer we needed to ensure the measurements would remain the same. Of course when it came time to install the shutter the bay window measurements came out smaller. I contacted Sheldon and despite his busy schedule during the holiday season he stopped by the house to look over what needed to be done. Sheldon was honest in that he would not be able to get to me until after the holidays which was fine with me. He explained that he needed to obtain a specific bit in order to properly shave down the shutter to fit into the panel. Not soon after the holiday season Sheldon an his crew arrived and began the job. I appreciated the fact that Sheldon explained to me what he was doing and kept me apprised when running into an issue. (He was tenacious in resolving said issue!) Both jobs turned out terrific and I plan on hiring Sheldon again for other projects that I have coming up. After they left I went to grab my broom to clean up and lo and behold they left the job spotless!! Great job ! Quality work at a great rate. I would definitely recommend this company for your projects."

"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

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.

Yes, selecting double glazing or low-E coatings to reduce energy costs.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

Picture windows last about 20 to 50 years, depending on the material, your location, and how well you maintain the windows over the years. Materials like vinyl and aluminum may not last as long, while fiberglass can last many years. Wood will last decades if you keep up with maintenance. Homes in areas with harsh weather throughout the year may cause windows to have shorter lifespans.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.
