Easiest Construction Experience with an Amazing Result!

We are super impressed with the quality, speed as well as the overall experience of working with NJSA. Even during these crazy COVID times when factories are working at half capacity at best and municipal buildings (for permits) are closed or on a reduced schedule. NJSA was still able to push through all the difficulties and build us a beautiful huge sunroom in a matter of a few months! They are very easy to work with in many respects. Jim, is a great listener and has been ablet to attend to all of our desires – regardless how unique some of them were – like a custom glass door with a doggy door, or raising the ceilings an extra foot, or replacing the knees wall with vinyl. He was also very flexible to work with us as we kept changing and upgrading our project once it was already on the way. We even had to submit a modified plans packet for a permit – but even that didn’t slow down the process as other work was done in the time we waited for the update approval. Ryann, the main contact person, is amazing - she is very professional, friendly and very easy to reach. I can send her a text message and expect a response in literally minutes! She always will let you know the schedule, when and who will come and on what days. And if a crew is scheduled to come work that day they are very punctual arriving right around 8am, taking one quick lunch break, and working hard throughout the day. And of course, the final product is even better than we have imagined! The quality, look and feel – we are absolutely ecstatic! This is really now our favorite room in the whole house. We would, with out any reservation recommend NJSA to anyone. They are affordable, good quality work, very reliable, quick, and the whole process is the smoothest we’ve even had for any construction project – and we’ve had a lot of them.

Thank you so much for the kind review, Maria! It was an absolute pleasure working with you guys! We hope you get many years of enjoyment out of that beautiful room!

Job Done exceptionally great.

Starting from design stage the project was handled very professionally. Structure is very robust and well designed. Even the building inspector was impressed. I am very pleased with this project.

Service, Support and Quality: Better Than Expectations

The service and support we received from NJSR was great when dealing with the city regarding variances and every step of the way. The final product was better than we expected. We are truly satisfied either the job NJSR did for us.

Best Choice Ever

We were looking for sunroom in NJ, we found couple companies to get estimate. Alex was our salesman who is really knowledgable, patient, showed us all the materials, gave us all the details about the sunroom. Really appreciate for all the help. The whole process is really clear, Ryann explained us each step what the contractors were going to do. They did really professional jobs, they did quick and wonderful work. they kept everywhere so clean, we don’t need to worry nothing. Thanks for the wonderful job. I would recommend NJSA to whoever wants to get the sunroom. They are always the best choice you would ever make.

Thank you for the kind review, Nicki! We love hearing about our clients positive experiences! Enjoy the sunroom!

Love my Sunroom and Professionalism

As they say, sometimes you are very lucky to get the right people at the right time for the right job. The question came for us if we want to expand basement or to add Sunroom. I think we took a right decision of doing Sunroom first since we use it now daily..Especially these days of WFH, we really thank NJ Sunroom for doing such professional work which is perfect addition to my house. Jim and Andy are customer friendly and have done all as expected and agreed upon. Ronaldo in Andys team was very good. Thanks NJ Sunroom . Keep up the great work

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

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!
