Meeting with Peter in the beginning was very impressionable. That impression remained throughout the process to completion of the project We appreciate the Professionalism of those we came in contact with . Evidently, this is an organization comprised of people of character, something not often seen in service related companies.

Real Pros

You guys are real pros. Your installers are excellent and the product appears to be solid and will probably last for years to come. You also hit all of your promised deadlines.

Outstanding conservatory roof replacement

I needed to replace the roof of my conservatory so I reached out to NJSA and spoke with Paul, who was very knowledgeable. He walked me through the entire process over the phone and also came to the home to look at the roof in person. He designed the roof and showed me how it would look. After that, Ryan and his installation team worked on it for two days. The team was very professional and did an efficient and great job on it. The service was unmatched. I highly recommend to use them for any roof replacements. Thank you!

Beyond our expectations

My husband are are new homeowners, having lived in apartments many years. We have heard the horror stories of construction projects but from the very first meeting with Jim (in our home) we were comfortable with this companies, its standards and its products. Brian was instrumental in helping us navigate the morass that is construction variances in our town, a process that slowed production down significantly. But once the permits were in place, NJ Sunroom Additions was ready to go and helped us tremendously in preparing the site (we had not realized we needed a place to dump the dirt that we dug up). Every single person the foreman Andy has working on our project was prompt, clean, polite and professional. Even (the other) Andy was so patient and accommodating with me when it came to how we wanted the floor tiles laid. We couldn’t be happier - except that now we are spoiled for any future construction projects! We are fully aware of how lucky we got with this team and we (and our pets!) are thrilled with our new sunroom. Thanks to all at NJSA.

Thank you so much for the kind review, Victoria! It was an absolute pleasure working with you and your husband to design your brand new sunroom. We hope you get many years of enjoyment out of it!


Installation went very smoothly with a very professional crew. Although only 4 days since the new roof was installed we are very pleased. Sales staff were straight shooters and easy to work with.

Oops I Did It Again

I added a Sun Room last year. It was such a great job and experience that I decided to convert my front porch into a small sun room. Same great work and people! (Plus it actually made the house warmer this winter!) They stand behind everything and if there is the slightest concern - they are on it!! They do not leave you once the job is done.

Thank you so much for the kind review, Trish! I know I speak for everyone here at NJSA in saying that it was an absolute pleasure working with you, not just once, but for the second time!

Great company

Honest and professional. Peter & Paul are very nice, made appointments quick and on time. Isac and Paulo are two great installer and have done a nice job to replace my roof. I mistakenly authorized $5000 more to the payment, Ryann called me to point it out. That alone says a lot. Would definitely use them again. Actually this is my second time using same group of people. The previous company (same sales and installer) built my sunroom.

We Love Our New All-seasons Room

From beginning to end everyone was courteous, professional and knowledgeable. Any issues that came up were quickly resolved. Our sunroom was finished on schedule. We have dogs and the team made sure that our yard was clean when work was finished each day so that the dogs couldn't get into trouble. We love our new room and have spent every day in it since it's completion. We highly recommend NJSA!
