"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

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

Use a high-quality caulk with silicone around your windows, as it’s waterproof and shrink-proof. Or, you can use a caulk consisting of polyurethane or acrylic if you want to be able to paint over it. Caulk made from silicone is not paintable. Avoid using inexpensive caulk that has a resin or oil base. These caulks will not last long and may shrink and pull away from the window as temperatures go up and down.

Storm windows are well worth the cost, especially if you live in an area that experiences extreme weather, like hurricanes, a lot of snowfall, or high winds. These windows not only help keep you and your home safe during a storm, but they can also save you thousands in storm and window damage costs.

Soundproof windows can’t completely block all noises, but they will significantly reduce sound from the road, sky, or your neighborhood’s weekend activities. Choose a soundproof window with an STC rating of at least 45 to block bass tones or loud conversations. Laminated glass windows can reduce noise by 75%. You can also add noise-reducing curtains to further muffle loud noises.

Yes, you can replace the frame around a window by completing either a partial replacement or a full replacement. With a partial replacement, your window specialist will remove the trim around the window and replace or repair just the damaged portion. For a full replacement, your tech will need to remove the window, replace the frame, and then reinstall the window.
