"Larry, Valerie and Larry Jr. did a terrific job installing our window film. They scheduled an estimate quickly, came when we were ready. They were very pleasant to deal with on the phone and in our home. They also helped us pick the best materials for our home."

"Team from Power completed the work on time and cleaned up well after work was completed. Windows were measured correctly so replacement windows fit perfectly and were quality Pella windows versus no-name windows offered by other vendors."

"Worthington Basement Health Systems did an extremely professional and high quality job on the egress window and EZ-Breathe Ventilation System. The quality of their work is impressive and the window makes my basement bright and safe. The ventilation system has taken the musty smell away and I actually want to spend time in my basement. I highly recommend them for your basement needs."

Windows FAQs, answered by experts

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.

Yes, home appraisers look at your windows when appraising your property to determine the market value of your home. They’ll factor in the type of windows, quality, condition, whether or not there are screens covering the windows, frame materials, size, insulation, and more to come up with an unbiased property assessment.

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.
