"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"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 questions, answered by experts

There are many standard window sizes. The most common windows, single or double-hung models, typically range from 2-feet by 3-feet up to 4-feet by 6-feet. Of course, sliding windows will be wider than they are tall, though the standard sizing follows the same measurements.

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

Contrary to popular belief, wavy glass in older homes isn't caused by warping. The blowing technique used to create windows in homes dating back to the 1700s, 1800s, and early 1900s left behind small bubbles that create a wavy effect. If a glass window is functional, there's no need to consider wavy glass damaged. In fact, many homeowners prefer the old charm of wavy glass.
