NJ Design & Build - Najmna 27 Google reviews WTD MIC2024-12-24 Engineering and permitting process was good and fairly seemless. Price was competitive and initial demolition was good as expected. Tile layer is skilled and professional. Some of finish carpenters, etc. we’re lacking experience and quality control as appeared to be a shortage ok skilled labor. Moe the GM was very responsive, flexible, and pleasant to work with. Sean Canto2024-11-19 It was nice to be able to have everything done by one company, from architect to construction. Alan Reitman2024-11-09 Did a great job fixing what another contractor really messed up. They are very professional and experts in what they do. Jen U2024-11-09 The contractor and his team did a really good job on my daughter’s bathroom project. Highly recommended. Jennica Marie Uychiat2024-11-09 I could not recommend this company enough! They did a fantastic job in fixing and finishing my guest bathroom that the previous contractors did not. Mo, the owner, works with you every step of the way and explains what you need in detail so you will feel at ease with the whole project. Everyone in his team are always on time and very professional, kept everything clean specifically Steve for going above and beyond to finish the project on time. Super happy with this company and will definitely have them again in future projects. Dennis Carnevale2024-09-12 I got my dream kitchen from NJ Design & Build thanks to the great team of Moe, Gaston and Joel. The price was right, the project was on time and everything turned out exactly how I wanted it. The communication with them was great and they made sure everything was done right. brian goldsworthy2024-09-11 They worked hard to get my already mostly built shed approved for a permit at a good price. Would definitely recommend and use them again for future projects chadi saker2024-06-05 Thanks mohamad for best service T T2024-05-23 I am absolutely thrilled with the services provided by NJ Design & Build. From the very start, they demonstrated exceptional professionalism and attention to detail. Their pricing was competitive and transparent, ensuring no surprises along the way. The team began by meticulously handling the design and permit phases, showcasing their expertise and commitment to getting everything right the first time. Their efficient process kept us well-informed and confident in their abilities. Now that we're in the construction phase, I am incredibly impressed with how NJ Design & Build manages the project. They are on schedule, and their follow-up is impeccable, ensuring every detail is addressed promptly. The quality of their work is outstanding, and I can see our vision coming to life beautifully. I couldn't be happier with the progress and the way NJ Design & Build handles every aspect of our project. Their dedication and excellent service make them a top choice for anyone looking for a reliable and skilled engineering and general contracting company. Highly recommended! Atheer Gabola2024-05-16 I contacted three general contractor companies to remodel my kitchen, as I was concerned about the project's duration. Two companies had sky-high prices and estimated a timeline of 5-6 weeks. I ultimately chose NJ Design & Build due to their reasonable prices and perfect timeline. Their work and attitude were amazing, always on time, and kept everything clean. I was so impressed that I ended up upgrading my bathroom as well
