Christopher Mangone

Greg and Bryan did an amazing job designing and building our deck and basement. They were collaborative in designing both projects, listening to our feedback and providing modifications that met our needs. Once aligned, they executed the build flawlessly, keeping us informed throughout the project. In the end, they delivered a deck we will have for many, many years and a basement our kids will play in for throughout their childhood. I highly recommend working them!

Comment from GN Builders L.L.C:

Thank you for the kind words Chris! It was a pleasure working with you and for you.

Marinet Jacob

Greg is an excellent designer. Very knowledgeable about kitchen design. Designed in 1 day 2 different layout options for our kitchen remodel. He discussed in detail the pros and Cons of both. Explained very thoroughly through a 3 D model all the cabinet sizes. He even applied life size people walking around the model to visualize it all. Never makes you feel rushed or annoyed no matter how many changes he makes. Highly recommend Greg for every home renovation project.

Greg did a wonderful job designing our home addition. He was responsive to our feedback and made adjustments as needed. Would definitely recommend his services to anyone requiring 3D design work.

Greg has everything you'd want in a contractor. He is knowledgeable and reliable, he will call back when he says he will and show up when he promises unlike many other contractors who never call back or show up when they are supposed to. I reached out to Greg with concerns over a problem with my front porch and he replied to my message within a day! Although he doesn't provide services in my area, he agreed to come for an on-site evaluation. He showed up on time and afterwards sent me great 3D graphics pointing out the specific problems and how to address them so that I can have a local contractor do the work needed and not get scammed. Greg is a great contractor, dependable and with excellent customer service. I would have hired him to do the repairs in my front porch without a doubt, but it is so unfortunate that I am outside of his service area.

Wow, Greg offers a great service at a very reasonable price. I provided him a crazy hand drawing of a house and he turned it into a a real house design. Then we spent time in a virtual session where we changed even more things. Shortly after that he gave me all the plans in PDF form. I would highly recommend his service. I had been experiencing a lot of frustration with trying to design it myself via app. He made it fun!

Greg was amazing with our basement improvement project! He went over the measurements and created a plan of our basement with all the details added, so we could see the design in 3D. We were able to see different options for the floor, walls, and ceiling, as well as other things we were adding. He is very professional, helpful, and patient, and I highly recommend working with him!

Greg is wonderful! We just bought a home and were unsure what to do with the floorplan. He came up with two great design choices and listened to everything we said and added them to the floorplans. We can't recommend hm enough. Thank you so much Greg!

Greg was the consummate professional. He drew up 3D renderings for my new custom home and pretty much brought it to life. He was very friendly, patient and knowledgable. He also gave us some great ideas that we gave to our builder.

Greg rebuilt a linen closet for us, creating a new wall. He was very professional, personable and did excellent work. He responded quickly and worked very efficiently. He went out of his way to do the job correctly even if it involved something I didn't know to ask for. It felt that he worked with the same sense of responsibility and care as if it was his own house. Highly recommended.

Greg is probably the best contractors who will combine his immense knowledge in construction, materials, local township bureaucracy in making economical, aesthetic designs and follow it up with great finished product. His 'one customer at a time' approach guarantees project completions on time.

Greg was a real pleasure to work with. He rebuilt our porch, which was unsafe and falling apart. He was helpful from when we first called him, created a graphic layout of the project, was detailed, diligent and thorough. The fact that he's friendly and a nice person was a major bonus. Even other contractors working for us doing different tasks liked Greg and commented how he was focused and detailed oriented plus he enjoys his work! He did top quality work and worked on creating a reasonable budget and timeline. He's a great craftsman and takes pride in his work. We highly recommend him.
