J&J windows replaced two twin window units in two of my lower floor bedrooms. I am a very happy repeat customer, as they replaced 24 windows and a sliding glass door in my former home. J and J always does superior work and I completely trust them for advice on any current window problem I might have, expertise in recommending products and getting the job done in a professional and superior way. Chris and Jenny performed both the work on my former home and my current home. I was so pleased that they would be doing the work again for my current home and it put my mind at ease that the job would be done expertly. There was no wall damage when my windows were replaced and they were able to reconnect the alarm sensors from the old windows. J and J always does a fantastic job from the very beginning when Jake comes out to discuss and estimate the job- he is full of excellent advice and recommendations to the execution with Chris and Jenny doing a amazing job to Jan and Kim who handle scheduling, warranty and follow up. I couldn't be happier with this company!

J&J just install all of my replacement windows. They did a fantastic job. Their workmanship and dedication to professionalism was second to none. I’ve been using J&J for all of my siding guttering for over 35 years. They originally installed storm windows on my home 35 years ago. The replacement windows are of excellent quality. They look amazing and I am so pleased with all of their work and the final product. Communication with the office in keeping me updated on the status and scheduling was great.

Jake and his team are amazing! I have used them several times at both of my homes. They are responsive, professional, and do fantastic work. Recently, they replaced the siding on my house. It turned out great! I will use J&J every time!!

Great service!! I have now received service twice from J&J (once for siding repair, once for replacement of a 30' high atrium window) and they have been awesome. Great communications from start to finish, courteous staff and excellent results. I would highly recommend them.

Wonderful doing business with J&J Siding & Windows. My new front door is exquisite! The staff is more than accommodating and professional. I love my new shutters as well! I highly recommend using J&J. Happy 70th Anniversary!

I had a storm window sash glass that was broken due to a rock while cutting grass. I further mangled the sash trying my own fix to no avail. Since the type of window has long been discontinued, I couldn't find anyone in the St. Louis area willing to fix it without a total window replacement. J & J not only offered to take a look but was able to reassemble the sash with a a new piece of glass! They saved me from a bind for sure! Everyone was very friendly and helpful and I couldn't be more thankful. We have a window project planned in the next 5 years and will definitely be keeping them in mind!

I've used J&J for windows, doors and siding projects. The value of the service and quality of work consistently exceeds the price. For the services offered, accept no substitutes!

I had a window break suddenly during the cold wave of January, 2023.I did some research and ended up calling J & J. They sent a guy out then emailed me a quote. Much of the information sent to me needed a rework before a resend. Not a big deal.Quote was pretty high so I negotiated the price and they agreed to reduce it by a little. The person I was working with went to see if there was anything else more they could do since it was still pretty costly.. Not to mention projecting a time frame of anywhere from 2-6 months.Fast forward to the check back phone call (same day) and they bumped the price back up!?Red flag ?I had to probe to get the person to acknowledge it. He was probably uncomfortable, but still.. You gotta own it whether it was a mistake or not. Instead I was just getting brushed off. I lost interest completely & put a hold on moving forward. I chose to shop around & sent a final email about the validity of the less expensive offer. No response at all.I got ahold of a local biz around me & the owner made it out within 3 days. They will have the work done in about 2 weeks. I’m saving over $110 in comparison with A.M. Richards Glass Co. instead of going with J & J.I’m not saying don’t go with these guys because maybe this was a one off & I don’t know what goes on behind the scenes but this was a pretty mid grade first experience for me as a new homeowner.

J & J did a wonderful job adding a window where there was a brick wall! The work went so smoothly and the new window mimics the other windows in the house to look like it has always been there. They did an outstanding job. This is my third. house that I have used this company for. Great prices and a great job!! I highly recommend them.

As far as friendliness with sales goes I would give them 5 stars! As far as product goes & quality of the product or willingness to fix the issues with their windows. I'd give ZERO stars. The window themselves are ok but they told me for 2.5 years now there is not much they can do with the locks on these windows.. I have literal ICE inside my windows and sliding glass door in cold temperatures. I've called over and over with little returned phone calls & not much head way. I hate leaving bad reviews but I'm hoping I can help someone else. Pictures to prove it! Same problem since the first winter! There are other options! This is their "Higher end product".

We had a great experience with J&J Siding. Jake was easy to work with and communicated well throughout the process. They were able to install our siding ahead of schedule. They answered all of my questions and addressed concerns promptly. We've received a ton of compliments already and are very happy with the work!

J & J Siding & Windows installed 11 windows and 2 sliding glass doors for me. Their product was exceptional, their service was outstanding and their staff were very professional and did an excellent job. They cleaned up very well and we were very happy with both the windows/doors and the installation.

The repair of my patio sliding door has been so great and easy. I'm so happy I emailed them! I've been procrastinating fixing this, and they've been wonderful to work with. Couldn't be happier with how things have gone so far. Thank you!

We received quotes from a few glass businesses in the STL area. We went with J&J Siding and Windows, and they did not disappoint! Professional, from proposal to the finished work of replacing 6 glass units in our sunroom. The old units were fogged. I cannot say enough good things about the work they did, and how wonderful it was to work with them! I would definitely recommend this company, best in STL in my opinion!!
