"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Egress Windows FAQs, answered by experts

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

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.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

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.
