"I have a large yard that has been neglected for years and it became a dumping ground for extra junk. A neighbor recommended Blueprint Facilities group after they completed some work on their house so I went online and setup a consult. They setup a whole plan with my choice of designs for property and immediately started the first project of junk removal. The whole yard needed to be cleared of all kinds of debris and leftover building material and junk. They were professional and meticulous in their work and detail and started the project practically immediately with the junk removal and cleanup. Thanks for your great service!"

Egress Windows FAQs, answered by experts

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

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

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.
