"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 questions, answered by experts

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

Whether or not you need permission to change the windows in your house depends on your local laws. If you’re enlarging an opening or installing a new window and need to make structural changes to the house, you’ll need a permit. In most locations, you won’t need permission if you’re just replacing a window with another window of the same size. The window installation company you work with will be able to help you navigate any planning permits you may need.

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.
