"We are very happy with Premier Windows. The quality and installation work was efficient and professional. We ordered just before the covid19 lockdown began, and wondered how it would come together. Being older, we worried about letting a crew into our home, but decided it would be a go. The crew wore masks, worked quickly and were conscientious of distancing. The workmanship was excellent, the product is of great quality, and we found Pat Patel, the company rep, honest and informative. Pricing, while still expensive, at $5950, was approximately 1/3 less than other estimates. We would definitely hire again, and will highly recommend."

"It went extremely well. Being female, many contractors gave me obscenely high quotes and didn't detail out prices (which I requested). Working with John at Best Windows was such a pleasure. He listened to my needs, was candid, honest, and detailed out pricing. Also, he provides the highest quality service for the best price. His team (pleasant & professional) Installed 14 windows. I expected minor issues. And John/team were quick to respond and fixed them immediately. I highly, highly recommend Best Windows."

"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"I highly recommend Windo-Well Cover Co. They were here when they said they would be, came prepared do the job even if it rained, and went above and beyond by cleaning out the window well before installing the cover. I am happy with the look of the cover, but am especially pleased with the strenth and durability of the cover. We will use them again to cover additional window wells."

Windows FAQs, answered by experts

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.

Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Contrary to popular belief, wavy glass in older homes isn't caused by warping. The blowing technique used to create windows in homes dating back to the 1700s, 1800s, and early 1900s left behind small bubbles that create a wavy effect. If a glass window is functional, there's no need to consider wavy glass damaged. In fact, many homeowners prefer the old charm of wavy glass.
