"Next time you walk by an egress window on one of these flipped homes - check out the workmanship - crooked, leaking glue out the sides, certainly no permit. I know this because I have witnessed it AND I called one of those "cheap" window people for an estimate (notice how they are ready at the drop off a hat and then drop out of sight when there are problems? The window placed by Egree Inc is perfect. Was it more expensive - not much more than as egress window placed in 2013 that was equal in quality. It was also permitted, inspected, and sits level without leftover glue seeping out the sides. Was there a wait time - not more than I would expect from any quality provider. I was kept informed on the timeline and the window was completed as promised. BONUS - the workmanship is guaranteed and the company will be around to stand behind the workmanship. Excellent work."

Windows questions, answered by experts

Bifold windows work by using a track that allows panels to slide to the side and "stack" so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you’d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they’re open.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

A common way to modernize arched windows is to install interior window treatments that allow light through the curved portion up to and let you cover the bottom portion for privacy. You can also install plantation shutters to make an arched window look more modern. From the exterior, arched windows can appear outdated if they’re coupled with ornate trim, so toning down the decor can make your window look more natural with a modern design.

While some homeowners are under the impression that triple-pane windows can help to reduce sound, the truth is that triple-pane windows will not be much quieter than double-pane windows since having a third pane doesn’t make much difference in sound transmission. If you’re looking to reduce sound, you should consider installing laminated glass windows.

Impact windows are absolutely worth the money if you live in an area prone to hurricanes. Though expensive, impact windows are built to withstand hurricane winds up to 200 mph and theoretically won’t break even if flying debris, such as mailboxes and lawn chairs, is smacked against the glass. A single broken window during a hurricane can destabilize the pressure inside your home, which can cause walls and the roof to collapse.
