National Energy Contractors

We had them build a 3 season sunroom over 25 years ago. We have had no issues. We love our room. They also have done roofing, windows etc. We are pleased with all the work they have done.

I would not hesitate to recommend National Energy Contractors and Peter for your home improvement project. From the beginning, they were very professional. I was especially impressed with how responsive Peter and John were with any concerns or questions I might have. The job did take longer than I had hoped, primarily permitting issues, and there were a few "bumps" along the way, but the end result met or exceeded my expectations.

National Energy Contractors did a wonderful job adding a portico over my front porch. It was difficult finding a contractor who wanted to do a small job like that. Peter, the owner, was very happy to do this kind of job and was able to fit it in between other larger jobs in the time frame he had originally given me. He was very willing to work with me to find a design that would keep the cost reasonable while still delivering a quality product. I highly recommend Peter and his company.

I would highly recommend National Energy Contractors for their outstanding work on our new sunroom. After discovering their booth at the Naperville Rib Fest last year, we sought quotes from multiple companies. Although National Energy Contractors were not the cheapest option, they provided undeniable evidence of their exceptional craftsmanship. Dealing with contractors can be intimidating, as not all of them follow through on their promises. However, Peter Gatsch, the owner of Nat'l Energy, alleviated our concerns by sharing numerous favorable reviews from satisfied customers.

Throughout the entire process, Peter maintained constant communication with us, starting from the moment we signed the contract. The project involved multiple stages, from securing permits to laying the foundation, building the room, and adding the final touches like siding. Each crew of workers demonstrated professionalism and pleasantness. Their work ethic displayed expertise in their respective specialties, and it was evident they were passionate about their craft.

Although we encountered a few delays, the end result was well worth the wait. The sunroom is of the highest quality and solidly constructed. In hindsight, I would not have chosen a different builder, even if they had promised a quicker completion time. I am extremely satisfied with the final product, and I trust National Energy Contractors to deliver exceptional workmanship.

In conclusion, National Energy Contractors surpassed our expectations by creating the most beautiful addition to our house. Their dedication, professionalism, and commitment to quality are unmatched. I highly recommend their services for any construction project.

The owner, Peter, is fair and honest, local to the area. He also has a thousand Dad jokes to share. He never fails to get a smirk and shake of the head.

We have used National Energy multiple times over the years for updating our windows, siding and doors. The quality of work and product are outstanding. We are so thankful for the dedication they put into a job well done.

Peter(president) came home and gave me a quote for my sunroom. He is a nice guy. He respects our needs and gave couple suggestions. We are yet to sign contract.

National Energy Contractors has excellent customer services. Their whole team worked so well, together to coordinate with me and my family . We have new energy saving windows and front door which help reduce our energy cost. Staff is very helpful when contacted. Definitely look forward to install sunroom soon !!!

Absolutely amazing! We had National Energy install brand new bay windows and siding. The quality of the installation is nothing like I have ever seen. Everyone I had the privilege of speaking to was very professional and informative. Peter Gatsch, the owner, came out and answered every question we had before our installation date. We couldn't be happier! Highly recommend National Energy Contractors for your home improvement needs!

Over the holiday season our sliding patio door had unfortunately suffered irreparable damage.
After hearing about National Energy Contractors from a neighbor, I immediately gave them a call.
I was very impressed by how smooth the transaction went. I called looking for information on a quote, the lady on the phone was very informed about replacement options and reassured me that this is normal this time of year and being somewhat a time sensitive issue, she could guarantee someone at my home the VERY same day for a quote. When Pete showed up just a few hours later, he was very polite and eager to help get my door replaced as soon as possible. Within 20 minutes he was gone and we had an installation date set.
Installation day came and the guys were very professional, polite, and thorough while working in and around my home. I would recommend National Energy Contractors to anyone I know after such a pleasant experience from start to finish!

We had NEC planing and installing a sunroom and we are very pleased with the entire project and how it turned out. Prior to NEC we had contacted a number of companies to get estimates and some general advice. Many companies didn’t show up, didn’t reply or simply had no plan at all.
Peter from NEC showed up on time with a plan in his head and after sketching it for us we had a deal. The permitting process was done by NEC including building inspection.
All contractors that showed up did a very good job. They cleaned up after themselves and where always professional and polite.
I have only good things to say about Peters crew and there work.
The sunroom turned out great and you can’t even tell that it was build afterwards. The room matches perfectly the existing house.

Thank you for your a job well done!

We have been very pleased with all the work that National Energy Contractors has done for us. A couple of years ago they put on a beautiful deck and offered us suggestions that turned out great. This year they replaced our roof, several windows and offered a low-cost way to make our peeling wood windows look much better. I would highly recommend NEC for any exterior remodeling need!

They built a sunroom for me and did a great job. Every timeline they offered me was kept. They followed up along the way. And finished the job before the date they said it would be completed. The quality of the work and the people who did the construction was top notch. I had an issue with a piece of trim, six months later. They came over and fixed it within a reasonable time frame. This company is worth your consideration.
