"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

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

The type of casement window you have depends on where the hinges are located, the number of sashes, the style, and how the windows open. Single casement windows are popular casement windows that use a handle or crank to open. If you have two casement windows side by side, you likely have double casement windows. 

Windows that swing inward can tip you off to having in-swing casement windows, while windows that open from the bottom and swing outwards are top-hinged. If you can open your windows by pushing them outwards like a door, you may have a type of push-out window.

Impact windows can last between 10 and 40 years, depending on how much wear and tear they receive. This is roughly within the range for standard windows; standard windows tend to last between 15 and 50 years. You can extend your windows’ lifespans by performing regular maintenance on them and ensuring they are installed correctly.

Removing a window isn’t a very long process. Depending on several factors, it can take anywhere from 20 minutes to upwards of an hour. The size of the window greatly impacts the time it takes to replace it. Accessibility is another big component. If it’s hard to reach the window or reaching it is dangerous, anticipate it taking longer. 

Lastly, if the old window is in poor condition, it could take longer to remove it safely—especially if the frame has wood rot and is structurally unsound.
