"They were responsive to every call, did the work professionally and cleaned up nicely.  We would not hesitate to recommend them to friends and family.  We had two leaning columns in the back yard that are now straight and piered so they will never shift again.  They then removed a large area of cracked cement and relayed.  It looks fantastic!

Egress Windows questions, answered by experts

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.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

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.

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.

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