"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."

"Foundation Repair - our house had to be raised about 3 inches. Frank and his crew were very professional, kept to their schedule. Frank spent extra time with my parents to explain the scope of work and minimize the disruption to their lives. His bid was very thorough and he was upfront with the fact that there could be additional cost based upon what the crew found once they exposed the foundation wall. Would definitely use him again."

Egress Windows FAQs, answered by experts

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

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.

There are a few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.

There are a range of egress window types available, including:

  • Single-hung: $100–$400

  • Double-hung: $250–$500

  • Horizontal/sliding: $150–$800

  • Casement: $200–$500

  • In-swing: $350–$700

When choosing a type of egress window, consider how you’d like to open it. For example, double-hung egress windows open from top to bottom and let plenty of fresh air in, whereas sliding windows slide open for easy access.  

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.
