"Absolutely love it!!! We replaced tub curtains with sliding glass doors. Work and quality are superb. It looks gorgeous. The price was very reasonable. Jose from Glazier helped us with the customization and design of our doors, explained everything in detail. We are very grateful to him and his crew; they are very professional. I will be remodeling another bathroom, and I am defenetly calling Jose from Glazier for my next project. Thanks Glazier, my bathtub looks amazing!!!"

Egress Windows FAQs, answered by experts

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

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.

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.
