"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."

"We had the main windows done by Power Windows in 2021 and now we had them do the windows on our outbuilding and mudroom. The entire process has been great from start to finish. The windows are fantastic, keeps the heat out in the summer and cold out in the winter. The sales(Davis, Jack, and Brad) and work crew(headed by Gus) have been very up front and professional. I highly recommend this company."

"They replace window wells which is not one of the categories here. The Window Well Guardian people are fast on returning calls and providing a quote. They were an excellent value and I would definitely use them again. What a dedicated team. They hand dug out the old window wells during a snow storm. Impressive!"

Windows questions, answered by experts

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

High winds can be harmful to casement windows and all types of windows. Because casement windows can swing outward, high winds could slam the window against the side of the house, bend the hinges, or even rip the window off of the hinges. If you hear some strong gusts outside, it’s best to pull the casement windows shut until it all blows over.

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, 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.

The gas between window panes, typically argon or krypton, acts as a barrier to heat transfer. This means it helps keep your home warmer in the winter and cooler in the summer by preventing heat from passing through the glass. This gas layer also reduces condensation by stabilizing the temperature across the window and helps minimize noise. Essentially, it’s all about improving energy efficiency and comfort while lowering those utility bills.
