We are very pleased with the work they did."

"Johnny came out provided a detailed quote, explained what needed to be done. We hired him. He and his team arrived early, they did a great job. Left no mess behind what so ever. He was the third contractor that we met with and was hundreds of dollars cheaper. I would highly recommend him to anyone! We are considering him for additional contracting work."

Egress Windows questions, answered by experts

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.

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.

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.

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.

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.
