"I called and the next day the sales rep came out to our building with samples to pick from and she was very informative about the products and professional. I had to call back in because i did not count the right number of windows to be done. And again the sales rep was accommodating and was able to add the windows 3 days before installing. Also was able to schedule a sunday Installation when the lab was closed. The installer was here early, very courteous , professional and efficient. I was able to leave him to do his work so i could get my tasks done also. Exceptional service"

Windows questions, answered by experts

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Installing energy-efficient windows costs between $325 and $2,000, averaging about $400 per window. You’ll have to consider cost factors like the window’s size, frame material, and type. Labor costs in your area will also impact the overall cost of the project, with window installation professionals charging about $40 per hour on average. Different types of energy-efficient windows include:

  • Single-hung: $150–$2,500

  • Casement: $150–$600

  • Double-hung: $250–$3,000

  • Picture: $200–$650

  • Bay: $480–$1,920

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

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.

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.
