JC Lilly Windows

What a wonderful experience! I’m glad our neighbors recommended J. C. Lilly for our balcony doors. Our condo was built with flimsy french doors that allowed melting snow to damage our wood floors. Sent a quick email to Jean and received a quote right away. Our custom doors were installed just a few weeks later. We absolutely love the new sliding doors and so do our pets, the cats get to enjoy a cool breeze on nice nights while we enjoy our new doors and hardwood floors. The installers were very professional and knowledgable, they got rid of the old doors and made sure to explain how the doors locked/​opened. I would recommend this company to anyone and would contact them in a heart beat if we are ever in need of new doors or windows. Thank you Jean for the best customer service and amazing product, it’s rare to find such a reputable business these days.

Would give 0 stars if I could but 1 star for the returned phone call on the same day. Very disappointed to find out that this company does not service the South Shore area in Chicago. I was told we only service Hyde Park, Evanston, and North. Well when I looked on line there were customer reviews in Oak Lawn, Arlington, Downers Grove, and Glenview all areas that are further than my location.

A 100 percent fabulous, woman-​run company in Chicago! Do not hesitate to call them if you are looking to have new windows installed. (note: they do NOT do repairs or restorations of existing windows). Take off old crappy windows and put in bright shiny new ones? JC Lilly has you covered.
I own a small condo on Chicago’s northside and while its typically pretty low maintenance (knock on wood) it was in dire need of new windows after the building settled (unfairly!) in one corner. They no longer locked properly, which is a hazard and after a few windy days where the windows actually blew into the house I figured it was time to get things fixed up properly. Noted, universe, noted!
I truly had no idea whom to call — but after some quick research on Unilocal and gathering a few quotes, I went with Jean and JC Lilly Windows. I couldn’t be happier. Jean and crew were great at coordinating with me (landlord) and my tenant to make the whole experience really painless.
For the first go, I opted to do all the most pressing windows in the house (3 larger ones in the living room and bedroom). These were done perfectly and after nearly 2 years are still in great shape.
Next up, I needed the kitchen ones replaced. though a smaller job (just 2 windows) the quote still came in very competitively with other larger companies. Chalk it up for the small operations! Hindsight is ²⁰⁄₂₀ and in reality I should’ve had them all done at the same time, which is better for everyone involved and streamlines the cost effectiveness as well. Lesson learned.
Highly recommended. Need new windows? JC Lilly is your hero.

I can’t say enough good things about this company — of all the people who have done work in our home over the years, Jeannie and Slavik (sp?) provided the best experience — ever… and our home is 130+ years old, so we have had a lot of work over the 20 years we’ve been here.
Our house was so much warmer this winter thanks to you.
After getting a bid from a friend of a friend for replacing all our window — it was great to hear from Jeannie that we only need 6 of our windows replaced… and at the end of the job, she sent a refund to us, because it ended up costing less than the quote — seriously… If you need windows — these are the people to do the job.

JC Lily Windows has replaced all the windows in two of my homes. The first was an old Victorian with odd shapes and sizes. Jeannie gave me lots of ideas that were both practical and nice in design. My second home is a Mid Century Modern with huge windows floor to ceiling and sliders. They kept true to home and didn’t just sell me the easiest product to install. They took their time and gave me beautiful thermopane windows that reflect the elements out and keep the heat and cold inside. Their prices were reasonable, they installed when they said they would and left my home the same way they found it. The owner Jeannie has been in the window business for over 30 years and she even personally cleaned the stickers off of them herself. I highly recommend this company.

JC Lilly Windows is the best contractor I have worked with. I have been in my home 30 plus years and have seen it all.
They just finished installing all new windows in my brick bungalow, and I could not be more pleased. Jeannie knows her products and her crew is exceptional. Slawek’s attention to detail was very appreciated and not one of my spring bulbs that are just popping up were stepped on. Love these guys. You can’t go wrong with them.

This may sound weird but i was redirected to go somewhere else for my window! i contacted them because i saw all the great reviews they had. Little did i know, they are not only great but also very honest. I have worked with many contractors during our home renovations and have been lied too many times. they could of had my business, but instead give me information that saved me a lot of money. Thank you JCLilly Windows for being honest, i feel secure and easy knowing you guys are looking out for my best interest.

How can anyone have a bad review about JC Lilly?!
We just had 9 new windows and a slider door installed and the process from beginning to end couldn’t have been smoother.
Yes, they are a very busy small business and they are honest about that up front. The prices of the windows are not the lowest you will find, either. But, the professionalism, friendly interaction and the reliable, high end work they bring to the table is top notch and totally worth it.
Not only was the owner, Jeannie, extremely knowledgeable about the products, her crew was exceptional during installation. They were clean, quick, and made us feel very comfortable about our investment in the new windows.
Thank you JC Lily for a great experience and we will definitely recommend you services to anyone in the market for new windows!

I can’t say enough of the great work and professionalism this company has shown. I own a 3 unit building and needed to replace a number of windows. I receieved a few quotes but they were the most reasonably priced out there. However, it was the people who made the difference for me. The owner and team were so accommodating with some of my last minute requests that I won’t consider another company for my windows on my next investment property.

This is my first post on Unilocal.So, I know some people will take it with a grain of salt. Jeannie and her crew, run by Slawek, we’re very professional, efficient and honest throughout the installation of my new windows and doors. Jeannie came out herself and did the initial measurements, and I mentioned that my next job was going to be replacing the gutters. She told me when Slawek came out to measure (measure twice, cut once), he would also measure the gutters and they’d give me a separate quote for them. During the job, you just get a vibe for the knowledge the installers have, and Slawek was impressive. His crew was mainly family, from his father to his brother. You know you’re getting deep experience, if you’ve got two generations of a family working on your house. The windows went up without a hitch, and the new doors and storm doors they installed are outstanding.
I highly recommend JC Lilly for your windows and doors… and gutters too.

Jean is a doll!
Had 27 windows replace in two days and two custom made entry way doors replaced in one day.
Her workers are respectful, honest and talented. What more do you need forget those bozos that advertise on TV.
This company rocks.

Like the reviewer Dan D. I too was excited to find a window company that might be able to assist me in replacing some large thermopane windows. The glowing reviews were very encouraging that I might finally get some windows replaced by a reputable company.
Unfortunately, after 3 calls, during two of which I spoke to Carol and on each occasion was promised I’d receive a call back from Jean, I never did hear receive a call back.
I fully appreciate a business that’s in demand, because one might assume that they’re in demand because they do good work. I just can’t imagine working with a contractor whom I can’t communicate with.
I’d look for someone else who’s more responsive when in need of some window replacement.

What a pleasure to work with Jean and JC Lilly. Highly responsive and great communication. The installation work was outstanding! The team lead by Daniel took great care and paid attention to all the details of the job, making sure that the site was impeccably clean and the work spot on. Highly professional. I would recommend JC Lilly for any window and door work you need.

From the informative consultation with Jeannie to the impeccable installation by her great crew, things went soooo smoothly. Use them. You’ll be glad you did. Plus, totally comparable pricing to everyone else.
We’ll be using the info she shared when we get replacement windows for our other house. Thanks so much, Jeannie!

After reading all the wonderful reviews on here, I was excited to have JC Lilly replace my exterior door. Sadly though my project must not have been big enough for her as she never called me back. I can’t give a good review to a business when they won’t even return your phone call. Even if she had called and said that she wasn’t able to take on my project but could recommend another local company that would do it, I would have been satisfied. So much for trying to help out the local businesses.
My advice for hiring JC Lilly is that you better have a big project or prepare to be ignored.

Adding another stellar review for JC Lilly.
End your search JC Lilly is the window and door supplier you’ve been looking for:
–Incredible customer service Jean is knowledgeable, attentive, patient and hands on all the way.
–Her team was impeccable, high quality of service, incredible attention to installation, my home was almost cleaner (inside and out) after the install than it was before.
I have a large vintage home and needed 25 replacement windows. I got several estimates and across the board Jean and her team was the best choice.
I love my new windows. Thank you JC Lilly!

I can not say enough good things about JC Lilly Windows & Doors. Jeannie is so professional /​really knows her stuff and was so honest when she initially came over — total rarity.
They just finished installing 7 windows and 2 doors (all in one day!) on our 115 year home and truly did a flawless job. Lots of improvements have been made to our home over the past couple years (including windows we had installed a few years ago) and quality wise, JC Lilly is by far the best.
Jeannie’s crew is so great, too. Really smart, skilled and very respectful of our home.
I only wish all contractors were like JC Lilly (or at least half as good)!

One word sums up my experience with Jeannie and crew time and time again: Perfection.
We use them exclusively for any door or window replacement. They are always professional, courteous and work hard to get it done perfectly. I never doubt their quality of work because I have never had a problem with any work they have done.
Jeannie is responsive to any question I have and her crew is as well.
I would never bother using someone other than JC Lilly. I just wish all contractors and businesses were like them.

Sitting and looking out my new windows I felt a thank you to J.C. Lilly Windows and Doors was in order. The quality of the windows and the work is outstanding and we are very happy with the final result.
It was obvious that we had to get new windows, but how many and what they should look like was something we figured out with the professional help from Jeannie. With her many years of experience we felt completely comfortable following her advises and the result could not have been better.
The process of working with J.C. Lilly Windows and Doors was easy, personal and professional. Her team knew what they were doing and when they left, I could hardly see that they had been in my house. On top of that, they worked on a very cold Chicago day. I felt sure that they would postpone our appointment, but they were on time and ready to go. I was very impressed.
If you are looking for new windows or doors, please have Jeannie to stop by. I am sure you will find her and her team very pleasant to work with too.

If you want the short version of this review all you need to know is this: AMAZING.
If you want more than that, read on.
Recently bought a townhouse with a ton of windows we knew were going to need to be replaced. As we have a custom color window and have to adhere to the association’s rules, our choices of vendors was a bit limited.
After much research, we had actually selected another vendor over JC Lilly as our initial concern was that the bigger company could do the job cheaper and quicker. Boy were we wrong. SO wrong in fact that after 12 weeks of waiting with this other vendor AND them ordering the wrong windows, we got them to let us out of the contract (which I respect) and return our deposit.
We went back to JC Lilly and in 4 weeks, they ordered and installed better windows for LESS than the bigger company. But I would be remiss if all I did was compare speed and price as the crew from JC Lilly is so much more.
To say the guys were professional, courteous and downright polite couldn’t begin to describe them. From the start to the very end, Jerry and the crew did everything to make us comfortable, explain what was going on, report back to us if they found issues and replace things as they went. No up charges to replace some rotten wood, no extra charges to cut and install casing. What we were quoted was what we paid. And given the size of the job, we appreciated that.
The crew did an amazing job installing the windows so quickly and with such precision, we couldn’t believe it. In two days they installed 17 windows, 2 sliding doors, replaced all the interior casing and capped all windows on the outside with aluminum capping to match our association’s requirements. It took them TWO days. Two days! Ridiculous!
Every corner of casing was perfectly cut. No caulk. Every window was cleaned when installed. Every crew member respected our home as it was their own. This was a major invasive job and we were so confident and relaxed the entire time. They even mopped the floors when they left!
Jeannie (the «J» in JC Lilly) was also on hand to supervise, assist, clean up after the crew, talk to us, pet our dogs (poor dogs barked their heads off) and kept the guys going with breakfast, lunch and coffee. A true team effort.
When you do such a major project like this and spend the kind of money it requires to be done right, you hope and pray you’re going to get a contractor who does what they promise and delivers a high quality service. JC Lilly did not disappoint.
If you have the chance to work with Jeannie and her crew, do it. You will be so glad you did.
