Very friendly, not pushy with sales, I feel like I got a good deal for the product and everything went smoothly. The installers were quick and efficient.

Outstanding local company! This is our third experience with Illinois Energy and we will continue to use them for future projects. The employees are professional and helpful. The work is always excellent.

I would highly recommend IL Windows & Siding for your door replacement needs. We recently needed our outdated front door replaced. From our initial consultation to the actual install day, the service we received was amazing. Everyone was courteous, knowledgeable about the product and pricing was very competitive. It was an overall smooth process. Plus, receive a ton of compliments on our new door!

I am very pleased with the service that I received from Illinois Energy. While the cost was not the lowest the quality of materials as well as the lifetime warranty, which is transferable, were major factors that I took into consideration when deciding to go with them. I was quoted that it would take 10-20 weeks for the door to arrive and they were ready to install the door right at 10 weeks. They worked with the city to get all the permits needed and provided me all the information so that I could get the approval through my HOA. They were very professional and worked with my schedule to find the best time to get the door installed. The team that came to install my door were very respectful and performed quality work. The took the time to make sure that everything was correct and then cleaned up all the debris that was left from the removal of the old door and the installation of the new door. The door itself is very nice and slides with the greatest of ease.

Second time using this company. Good quality and very professional service

Quality product! Great company to work with. We used them for a sliding glass door and will use them again.

2nd time using Illinois Energy. Job well done. Showed exactly when they said and finished in a timely fashion. Windows look great and the additional trim work they did was perfect. Crew was friendly and respectful. Would definitely recommend!

I had some windows put in. These people are amazing. Would recommend over and over.

We began a project to replace our home's windows in a phased approach starting in 2016. Each of the four experiences was as pleasant as the first. IE offered a one-year same as cash to offset the significant expense all at once.

From sales to installation to customer support, the Illinois Energy (IE) team that worked with us was knowledgeable, friendly, and professional. IE stands by its products and installation; any issues, IE will address them straightaway with a follow-up appointment. Best yet, the windows come with a transferable lifetime warranty. No other window company offers that good of a warranty.

Now for the product itself; I can not say enough about the quality of Illinois Energy's windows. They are custom constructed by the Amish. The windows are tinted, filtering out the damaging effect of the sun to minimize fading. The windows are sturdy, easy to clean, and aesthetically complement my home's interior and exterior.

We used Illinois Energy Windows and Siding to replace our front door 4 years ago and just a couple of weeks ago to install a sliding glass door. Their team was fantastic to work with. Derek was very courteous and thorough when picking options, their team followed up before manufacturing to make sure all the information was correct, and their installers did a great job and cleaned everything up. We will definitely be using them again for our next project.

We are extremely happy with Illinois Energy! Our doors are high quality and the installation was clean, thorough and quick. We love how beautiful they are!

They are very professional people to work with and answered any questions I had. They were fast and efficient and were done in one day!

A Transformed House & Garage Exterior by Lloyd & Susan M



Before we hired Illinois Energy to replace the siding and door & window trim on our house and garage we had always hired individuals or companies to complete work projects for us who were recommended by someone we knew. Such was not the case with Illinois Energy since we learned about this company via an advertisement, but we are very thankful we chose them. They transformed our house & garage from white 8” siding with shutters to an amazing-looking 6” blue siding with expertly crafted and installed white trim. We appreciated the professionalism, prompt communications and helpfulness exhibited by all the personnel we dealt with from sales, administration and installation. Ruben & Raul’s work crew, which included five other men, was absolutely great. They let us know their plans & schedules, performed their jobs well, sought our input for how we desired things to look along the process and made sure we were satisfied with ALL the work as it was being completed. We have commented to each other that it’s like we have a completely new place to live without even having to move! We would highly recommend Illinois Energy to anyone needing siding & trim work.

Illinois Energy Windows and Siding was phenomenal to work with. Everything from the sale to the installation-could not have gone any smoother. The installation was done in sub-zero temps and a snow storm. Everyone we have had contact with at this company has been friendly and professional. I highly recommend this company and look forward to working with them again.

My doors look like something out of HGTV. Beautiful Black French Doors add an amazing curb appeal and aesthetic. Upgraded from a single aluminum door with two sidelights, and was also cold every winter. Now, these puppies are starting to pay themselves back with my energy cost savings (no pun intended). Intallation was seamless, and professional and took less than a day. Even our neighbors are complimenting us on them. Thanks Illinois Energy!

Sales was very helpful in walking us through the process and options. The installers were excellent. They worked fast, clean, and efficiently. They answered all questions we had. They were very respectful. We are very happy with the work done and plan to eventually have the remainders of our windows replaced by IL Energy.

Professional, reliable company. I'm happy with my new sliding patio door. High quality and well installation.

My experience with Illinois Energy Windows & Siding was AMAZING from start to finish! The sales experience was smooth and simple with no pressure whatsoever to buy. While the wait for the product itself was lengthy (due to COVID), it was well worth it! The install was very quick and smooth...the guys even completely cleaned up after themselves. My installed garden window is absolutely beautiful!!! My only disappointment was that the installers did not wear masks during the install. I didn't push the issue, but just made sure to keep my distance and disinfect everything after.

The window installer did a great job! They arrived on time and the installation looks great. The new windows matched the existing windows.

Windows are top quality. Installation was quick and done neat. My house was left as clean after they left as before they arrived. Would definitely do business with Illinois Energy again.
