"I had Keith and his crew come and clean windows first at a home I needed to get ready to go in the market. They did such a great job and weee reasonably priced that I hired them to then come and clean the windows and powerwash my house. Again, they did an awesome job. Would recommend them to anyone."

"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

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

Before you replace your windows, check your home warranty. Many home warranties don’t cover windows at all, while some have specific clauses about what they will and will not cover and what might void the warranty. If you have any questions, reach out to your insurance specialist, and never make assumptions.

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.
