"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."

"The windows were pricy but the quality of the windows justifies the price. The crew that installed the windows were wonderful to deal with. They cleaned up after themselves. The project manager was very understanding when I needed to change the schedule due to weather. They accommodated to my schedule changes for installation. They were very professional"

Windows FAQs, answered by experts

Most windows last between 15 and 30 years. The exact life span depends on a few things, including the frame material, the quality and type of glass, the weather in your area, whether or not the window is installed properly, and more. You can always speak with a window professional about whether or not it’s time to replace your windows or if repairs would be more affordable. You’ll need to consider the cost of replacing your windows, the cost of repair, and the longevity of each solution.

The maximum protruding distance allowed for a bay window is determined by its flank angles. 30-degree flanks can extend about 13 to 14 inches. If the angle is 45 degrees or larger, then the bay window can stick out about 19 inches. If the window extends too far out, it would cause structural instability and safety concerns.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Steel windows are durable and last a long time, but not in all weather conditions. If you live near the ocean, these windows might not be the best choice, as the saltwater breeze can corrode the metal. Steel windows are also more expensive than other types of windows. However, with that high price point comes a sleek, distinctive design that many homeowners find appealing, especially for modern decor. You can also restore steel windows to get a longer lifespan from them, so they can last longer than vinyl, aluminum, and even wood.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.
