"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."

"Super friendly, quick and responsive. The entire process was transparent, I learnt a lot about windows and how to take better care of them just by talking to them and seeing them do the work. Also, they kept to agreed upon dates and time. I will not hesitate to give them a call next time I have similar issues."

"I have been rehabing my moms home to sell and thing have been REALLY stressful. I had two windows that were cracked that I have been looking to get fixed for more than two months. I have had several window companies tell me it was “impossible’ to replace glass panes in thermo sealed windows. I was quoted $10k for one window replacement 😬 Jon showed up like a miracle! He was extremely responsive to my initial inquiry, was onsite promptly to assess the two cracked windows and noticed another window that had a broken seal. He provided a reasonable repair estimate for the three windows and was back to complete the work within three business days! Jon was a lifesaver, his responsiveness allowed me to get the house listed yesterday ! I am SO grateful for Jon!!! If you have windows that are cracked, call Jon to get them repaired!!!"

Windows FAQs, answered by experts

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Tinting your windows will make your house darker since it will prevent some sunlight from getting inside. While you can choose a window film that is on the lighter side, there will still be reduced sunlight. If natural light is important to you, tinted windows might not be the best choice for your home.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.
