"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."

Egress Windows questions, answered by experts

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.

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

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

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.

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.
