Illinois Energy Windows & Siding Inc

Probably one the best experiences I had with a company in a long time. Sales , communication’s,install went flawlessly. Installer arrived at scheduled time a true craftsman that did quality work and clean up. Project looked amazing . And one the best warranties on window I could find.

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.

This is an outstanding local company! This is the third time we have worked with Illinois Energy and have always been satisfied. The employees are professional and helpful. The workmanship is excellent. Highly recommend.

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 We recently needed our outdated front door replaced.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.

We recently had a 60"x60" picture window installed, as well as two double-hung windows. The installation team was friendly and efficient, and the windows look wonderful. We are repeat customers and highly recommend Illinois Energy! -Mary Henderson

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!

We have used Illinois Energy twice for our windows. Each time has been great! The most recent time we had a minor issue after installation and they were quick to respond, and fix it. We love our new windows and couldn't be happier with the overall experience!

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.

Workers and back office is terrific. Still can't adjust to the high cost of window replacement generally, otherwise I would have given 5 stars. These guys were prompt, professional, responsive, friendly, helpful, and their quote was below others we had received. Seems like a business that treats customers the way they'd want to be treated.

We are extremely satisfied with the services Illinois Energy provided. The doors are high quality. The installation was quick, clean and super meticulous. We love our doors!

The whole project went very well! The people were easy to work with and answered any questions I had. They worked fast and efficient and got the job 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.

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 installation went well. The installers were on time and very professional. The new windows matched the existing windows.

Everything went well as expected with our installation. I have no complaints. All the employees where professional and courteous. Would definitely recommend.

Flawless. Best professional install I’ve had in 20 years!!

We were very satisfied with the process of getting our new windows installed. Everything went very smooth and easy from the first meeting until the install. We will definitely be using them again on future projects!

We have used Illinois Energy Windows and Siding to replace all the windows in our home as well as the sliding door out back. From our first communication with them, they have been nothing but professional. Replacing windows and/or doors is a huge investment, and we researched and spoke to other businesses before we went with Illinois Energy Windows and Siding. After the initial installation, any issues or questions were immediately addressed with no hesitation. Although they didn't have the lowest initial quote, what we ended up with was great communication and customer service, professional installers, a great warranty, and great looking, sturdy and reliable windows (and sliding back door) that will last a long, long time. Overall, what we received from Illinois Energy Windows and Siding is QUALITY. No regrets here.

I just had an $8,000 dollar bay window and two $1,000 dollar storm doors installed and I have been very unhappy with my installation. The salesman while great to work with is where my good experience with these folks ends. In fairness the gentleman who installed my storm doors did a pretty good job, but my issue is with the Bay window. Sloppy finish work on something that expensive is not acceptable. I wish now I had just went to Home Depot. I did have a gentleman stop by my place the day of the install to collect the rest of the payment and discuss my issues with the install and he did agree it wasn't the best work they could have done. He advised us that they would have a service tech come out generally within a week and address our concerns. He advised us that he was going to collect the rest of the payment minus 600 dollars until the work was fixed/finished. We did notice that they charged us the entire amount, not the amount they agreed to charge us until our concerns had been addressed and despite the photos being passed along and following up with an additional picture being sent to their service email address (that they requested) we have not seen or heard from them since the day after the windows had been put in. Based on the installation alone I would not recommend this company. Its a shame as they are a local family owned business. We do not intend to ask them to fix their work any further, we can see now that they have collected their money, went back on their word, and essentially quit giving a ****. We will just pay a second company to come out and clean up their sloppy install and move on. 8k on a single window not well spent.

We used this company over 20 years ago to replace windows in a previous house. When we needed a new front door package for the current house we chose them again. Products are outstanding quality, fairly priced given the quality and all processes are completed from order to install with upfront honest communication. The installers are wonderful, knowledgeable and very courteous.
