"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"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."

"It went very well considering the weather did not cooperate. Pete's crew came promptly at the time scheduled to do the power washing and clean the gutters even though we were experiencing light rain showers. They did an excellent job. They even power washed the mailbox post even though it was not part of the work requested. Because it was raining and the deck needed to dry before applying stain, the windows and stain application were scheduled for 3 days later. Again, Pete and a crew showed up that Saturday at 8am and worked until 6pm. He also used a moisture meter to make sure deck was dry enough to stain (there had been a brief light shower the day before). We have a very large deck, so they were not able to complete everything. Pete returned the following Tuesday to finish staining, repair the lattice and water proof the wood along the walkway. There was a small section of grass that somehow had been damaged when the crew was applying the stain. Pete went home where he happened to have some sod and brought enough to repair and cover this section of the lawn. Through the entire process, he was very proactive with phone calls and emails and responsive to all questions and inquiries regarding the work. His crew was polite and worked hard. I very pleased with the results."

"A young and energetic crew (in attached photo) arrived on time (9 a.m.) and worked through lunch to complete our new Bay window by 3 p.m. All materials and workmanship are first rate. Color match on the exterior window trim was perfect! I had lots of little requests on touch-up detail work, and they met every challenge. All our questions were answered with a full demo on how the window features, sliding windows and screens, work. We look forward to their return for a second project."

Windows FAQs, answered by experts

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

If you decide to forgo your old windows and upgrade them to modern day technology, there may be some people interested in the old windows. You can try selling them on an online marketplace for around $50 to $100 each (so long as the window wasn’t damaged during the removal). This can also help off set the overall price to replace them.

If you live in a colder region, consider installing double- or triple-pane windows with low-E coatings, which can trap heat and keep your house warm. In hot areas, windows with reflective coatings and insulated frames help keep cooling costs down. If you experience a lot of extreme weather, then impact-resistant glass might be a worthwhile investment. 

Visibility through tinted house windows or privacy film depends on the lighting. During the day, the tint or film typically prevents people from seeing inside. However, at night, if you have lights on inside your home, the interior will be brighter than the outside, which allows people to see in. You can choose from various shades of privacy film, from lighter to darker, to optimize the level of privacy you want.
