"I hired him in December but it took until February for him to get here to put it in.  The cost actually came in under the estimated cost.  The installation went poorly.  I told him that we needed a 36" door, thinking that's what my initial contractor put in.  He was able to make the door opening larger, without having to change much.  After putting the door in it looked good, except he had used another casement.  I told him that I would replace it on my own.  I'm now going to have to take down the casement again and adjust the drywall.  The new door leaked the first time we had snow.  This leakage stained the casement, but I think I will still going to be able to use it still."

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.

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.

The primary benefits of an egress window include providing a safe emergency exit, increasing natural light in a space like a basement, and improving ventilation. Additionally, installing an egress window can often increase your property's value.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

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