"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

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old 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.

The cost of window installation depends on several factors, including the window type, size, and frame material. Labor rates, the need for custom sizing, and any required structural modifications will also influence the final price.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.
