"We ordered a window from them the end of April. The beginning of June they came to put the window in. They had ordered the wrong size. The said that they would rush order it and we would have it in a month. After waiting a month and not hearing from them, we called to find out when the window would be put in and they said that they would check and get back with us. After many more calls we were told that the window wouldn't be in until July 23rd. We requested a refund and after many more calls were told that they don't give refunds. The window was finally installed on August 2nd over a week after they received it. We will never do business with them again.!"

"Our Larson storm door closer was caught by the wind and ripped the bracket away from the exterior door frame. Chris Engle promptly arrived when he said he would. Polite and professional, he accessed the damage and told me what he could do on the spot for the least amount of money. Not a pretty job for what he had to work with unless we wanted to replace the whole door and frame, but he made our exterior door and storm door useable. He also installed a wind chain on the storm door for added protection."

Windows questions, answered by experts

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

If your winter looks like heavy snow, freezing rain, or frigid temperatures, taking your screens out for the season can be a great way to avoid mesh damage or bent frames. Ice can build up and put pressure on the screen, especially in older or aluminum frames. Removing them also lets in more natural light during those shorter winter days and makes it easier to keep your windows clean. In warmer climates, it’s less about protection and more about preference. Some homeowners like the clearer view while others leave them in for convenience. Either way works—it depends on your setup and what you value more.

There are several ways to keep your existing windows from letting in noise. You can install sound-dampening curtains or other window treatments that help deaden noise vibrations. Make sure any gaps around the window are sealed with acoustic caulk. Installing acrylic or plexiglass on the inside of windows still allows you to take in the outdoor views while also stifling sounds from coming in and out. 

If you try all of these steps and still have noise coming in, it might be time to install new windows.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

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.
