"After submitting a request through their website about a bathroom addition, I received a prompt call and was pleasantly surprised by how helpful and knowledgeable they were. They took the time to thoroughly discuss the project with me, which made me feel confident and valued as a potential customer. Lately, it’s been tough just getting a contractor to show up, so when I saw a sign in the neighborhood and decided to reach out, I’m glad I took the chance. It's refreshing to find professionals who genuinely follow through and care about their work!"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

Egress Windows questions, answered by experts

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.

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.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.

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

Depending on size, material, and labor, two windows can cost between $600 and $1,600.
