"Dr. Energy Saver was very thorough in finding the comfort and energy issues in one of my customers homes. They showed the customer exactly what was going on, why they had any issues, and how they were going to solve them. They provided a prioritized list of solutions for them too so they could pick and choose the importance to the homeowner. All work was done in a timely fashion, was clean, and fixed their issues."

"I am so impressed with Comfenergy. The sales rep explained why we only needed to improve the insulation at the top of our unfinished basement walls, not the whole thing as another company recommended. So it was considerably less money than we thought we’d need to do the job. Brent and his assistant arrived on time to do the work and were so quiet that we weren’t inconvenienced in any way. I definitely recommend this company."

"I was very impressed with this company. We did not need to do this project after all, or I would have been very happy to work with them. The technician who provided the estimate was top notch! He explained everything and even took a video with his phone to show me his findings after he inspected the doors and doorframe. I would highly recommend this company based on my experience with them."

"I recently had an egress window installed in my home by JDS Home Improvement. I purchased the Rockwell Egress Window. This window brings in a lot of natural light and it's just beautiful! Jordan Jones put a hanger inside the cover of the window so I could hang a plant. Jordan,Joshua Jones and all of the work crew were very professional and kind. The quality of the work is superb. I even had a custom closet made that l am very pleased with. The installation of the window was completed in a few days. The staff cleaned up well. Due to the heavy equipment used,part of my lawn was affected. JDS planted grass seed and the grass has already sprouted in just a few days. If it were not for Jordan, this project would not have been possible. It is without reservation that I highly recommend JDS Home Improvement. I'm looking forward to using JDS Home Improvement for my next project."

"Roger and his son did a fantastic job on our egress window. He said what he was going to do, when he was going to do it and then did it. They worked out in pouring down rain to keep the project on track. The end result was exactly as we wanted it and even better than we were expecting. Every day Roger and his team made sure to clean up the job site before leaving for the day. Roger does more than just egress work and he will now become our go to contractor. I can't recommend him enough!"

Egress Windows FAQs, answered by experts

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

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

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

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.
