To any one who's thinking about replacing windows and doors, I recommend C and J Windows and Doors located Williamstwon, NJ. The owner, John, is with out question, a reliable and trustworthy person who cares about and takes pride in his workmanship. I live in an older home and some of my original windows were not installed correctly, John compensated for this mistake and did a beautiful job. I could not be happier! I will be calling him to replace my interior doors.

John Flowers did a great job installing replacement windows in my old cape cod. Knowledgeable, professional, and effcient. Work was neat and clean, caulking especially. He gave me an estimate to paint the extra trim around windows, and when i came home from work, i was surprised to find they were already done and without charge. Great character.


Thans you!

We are beyond thrilled with our new slider and windows from C & J's. Even with this past winter being so brutal, we have already noticed a signiicant difference in our energy cost, all because of the windows John recommenened for us and his expert installation. John was always on time, his work was meticulous, and he left out home spotless after completeing his work. I have already recommended his services to other and will continue to do so!


Thank you!

I would like to thank John Flowers and his helper for the fantastic workmanship on my new Bay window. They showed up on time, were extremely professional at all times and explained the process of what they were doing. My window was an extra large window with many difficulties. Not once did they complain, but rather, they made sure every detail was precise. They never stopped for lunch. Instead, they worked straight through until the job was complete. Once done, John took me around every aspect of the window to explain its function and why he did this or that. You can not find that type of worker anymore. We could not be more pleased. Thank you so much!

I would highly recommend John to anyone looking for a door or window installation. He was quick to respond to my questions, showed up on time and generally just a pleasure to work with. When Home Depot delivered a dented door for install, John went above and beyond to resolve the issue. He installed a door into our garage where there wasn't one originally. Framing and install took a single day and looks fantastic.
