"I had a foundation issue that caused a window to shift out of its casing. Window World was happy enough to help me with just the one window that would need to be replaced. The sale, scheduling to the installation was done very quickly and everyone was all very polite and professional."

"Highly recommend this company for windows. Had all windows in the house replaced with good quality energy efficient windows at an unbeatable price. Install crew was fantastic, and customer service is best I have ever had, after getting some caulk on one of our new screens, they ordered a replacement for us without having to ask them to. We had a quote from another company for windows with same energy ratings and similar construction but they wanted 3x the money for the job. Don't look any further than NuSash for your replacement windows."

"My words won’t do this company justice. Hire them and experience it yourself. We literally had our egress window installed yesterday and can’t even see any inside mess. Their entire crew is friendly and social. Curtis was willing to spend extra time with my wife and I talking about basement finishing without any obligation. I see this company as the Maserati of home repair companies.... 100% top notch."

Windows questions, answered by experts

DIY is possible with the proper tools. Professional installation ensures a proper seal and energy efficiency.

If your windows are drafty, fogging up between panes, or hard to open or close, it might be time for a replacement. Unexplained increases in your energy bills, rotting frames, broken seals, and noticeable noise from outside can also indicate it’s time for new windows. In addition, if you find yourself frequently needing to repair your windows, it’s probably more cost-effective in the long run to replace them.

According to the U.S. Department of Energy, low-E windows can reduce energy loss by 30% to 50%. But the actual effect of low-E windows in your home will depend on many factors, like climate, number of windows, window treatments, and more. In terms of aesthetics, you may or may not notice a difference in how your windows look or how much natural light shines through. But overall, low-E windows look very similar to traditional windows.

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.

Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more.
