"Craig the installer did a great job. I was pleasantly surprised by how sturdy the windows were - i picked window source's mid-tier level window. The day after my windows were installed the first storm of the season (snow, rain & ice) arrived and the windows completely performed as they should. I never realized what in eyesore my old windows were until i had these installed. i cant even tell how the wrapping on the windows improved the look of my house! I would definitely recommend window source & i did to a family member. Also, their quote process was quick, 1/2 hour to get a price. Window Source wasn't on my radar while i was requesting quotes on angie's list but they came up as a recommendation & i can't tell you how glad i am I hired Window Source to install all my new windows. A friend had windows installed by a popular chain & Window Source beat the quality and look hands down! If you are like me nervous about hiring a contractor you really know nothing about - i am here to tell you will be happy you hired Window Source. Thank you window source for making my 55 year old house look new!!!"

"The installers of the wallboard were quick and efficient. Did a great job hanging in our new 16 x 32 family room. Even with some of the patch work in other areas of the house they ensured the surrounding wallboard had screws to adequately cover the area before the taper came in. The man that taped and mudded was a true professional. His corners and seams are clean and overall the expertise of the entire crew was exceptional. I would certainly hire this company again."

Egress Windows FAQs, answered by experts

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.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.

How do you handle payment?
