Beautiful Sunroom / Great Company!

After multiple quotes there was absolutely no doubt in our mind NJ Sunroom Additions was our favorite for so many reasons. Their entire staff's professionalism and dedication to excellence was second to none. We had our room delivered the week before our State shutdown for the pandemic. Each week I would wonder if our project would be postponed but I was always assured by Ryann and Andy we'd press on and have this done ASAP. I really am impressed at the level of dedication the crew had during this whole project. Terrific company - Can't say enough! We are in love with our room. We're in the room morning till night! What a place to be in quarantine in too. :-) Thanks again everyone! Cheers

Thank you so much for the kind review, Jim! We are so happy you guys are enjoying that new sunroom! Thanks again for working with us!

Good Quality & Versatility

NJ Sunroom Additions produce a wide range of products. We picked the 3 season V Series, which provided the versatility we wanted. The sliding panels of memory vinyl are lightweight and easy to lift to any position you want, up or down. The room transforms from a water-tight, 3 season room to a fully screened porch in only minutes and really helps to expand the use of the space. Individual panels are also easy to remove if want to store them away or send out for repair (FYI...screens are permanently affixed and would need repair in place if ever needed). The technicians worked diligently to retrofit our porch as needed and button-up all the details in only 1.5 days of work. Great to see things happen so fast and with no hassles. Happy to show off the product to prospective clients. Thanks to the crew and the company for a great product and great customer service!

The Best Sunroom ever!

Our sunroom was finished about 5 months ago. We are extremely happy with the result. It looks lovely, well built, well finished. The insulation was great, it feels even warmer (without turning on the heat pump) than the adjacent part of the house! Everyone who comes to the house compliments us on our new room. The process was easy with Ryann establishing good communication throughout. Every person I had to talk to was friendly, patient, and willing to understand my needs and worries. Special thanks to Andy and his son who undertook most of the building work and were always nice and easy to have around. They helped me install a door which turned out to be more difficult than expected, and did so with great results and zero complaints. Again I was pleasantly surprised by the fact that the company honoured our deal and did not try to charge me more for installing that door. I guess they could have told me they would not do it, but instead they were always helpful and delivered an excellent job. I would definitely recommend NJ Sunroom Additions to everyone!

Thank you for the great review, Paola! It's always great to hear our clients sharing their positive experience with us. Enjoy that beautiful new sunroom!

Nerving in the beginning great at the end

I was disappointed when my did not start as promised by the salesman. But after talking to Ryann it was a great experience. My room is a piece of art. Even the difficult inspector in my town said so. Work well done it was worth the wait.

Thank you so much for the kind review, Julia! We totally understand the stress in waiting for that new Sunroom, but we are glad we were able to follow through and build you a sunroom you enjoy so much!


The guys at nj sunrooms did a great job. They were knowledgeable and worked fast. From the planning thru the construction everything went smoothly, the only hold up was the inspections that the town required. The finished product is well insulated ,and now is the main room for the family in the house.

Such a Relief!

My wife and I wish we had contacted NJSA from the beginning. Instead I paid a disreputable and dishonest sun room company over $100,000 to essentially destroy our home. That company is called "Simply the Best" and was a complete nightmare from beginning to end. It took them over a year and they never completed the job. Many times they just didn't show up at all. Leaks everywhere! Buckets of water everywhere - cascading down every wall! The entire room was ruined and unusable for years. Such an embarrassment! The company owner Alastair Cornel did nothing but lie to us and refused to fix their obvious mistakes. We could actually see sunlight through the openings in the roof. They are "Simply Crooked!" Eventually we contacted NJSA and what a difference! They developed a plan to remove all of "Simply the Best's erroneous and shoddy work. Their architect redesigned the roof area and removed the entire roof, and all the damaged wood work. Their new design was sensible and a beautiful redesign of the entire area. Their workers were polite and professional. Most importantly - they were skilled craftsmen. Everything was beautifully done! We love our new room and wish we would have used NJSA from the start.

Thank you so much for the great review, John! We couldn't have been happier to have been able to step in and correct the mistakes from "Simply the Best". Now that all those leaks are fixed, we hope you enjoy your new sunroom!

Excellent work

From start to finish, NJSA team members did an amazing job at replacing my polycarbonated roof with a permanent roof. Paul, Andy and his team are fantastic. Once the job started, they work on it till it was done. Always clean, meticulous and paid attention to the smallest details. Thank you Paul, Andy and entire team for a well done job.
