"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

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.

Installing a window well costs anywhere from $500 to $1,500 or more. Adding an egress window and well runs about $3,900 on average. Adding a window well cover to the project can add $200 to $700. A well cover helps protect your egress windows from weather damage and keeps them clear of dirt, debris, and wildlife.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.
