NJG Constructions being referred to me was the best thing to happen to the Cunning Culinarian! A year to the day tomorrow since I pickle up the keys, and I would do the whole thing over again with you in a heartbeat. I will never be able to thank your enough for bringing my exact vision to life with so much care, skill and efficiency.
Alina McKee, The Cunning Culinarian, Maitland
Highly recommended! We had a fantastic building experience with NJG Constructions and would not hesitate in recommending them. They completed the renovation to a high standard and on time! Nick was great at quickly responding to any questions or issues.
Wendy Hird, New Lambton Project
NJG Constructions were a pleasure to deal and work with. Their professionalism and workmanship was always excellent and our renovations exceeded our expectations. We will definitely be using them again for any future projects.
Barry Easton, Kotara
Nick and his team have done several projects for us. They are always on time, tidy, friendly, good communicators and their work is of high quality. Very obliging, patient and good problem solvers. They will certainly be working on any future projects.
Phillipa Kemp, New Lambton
NJG Constructions performed renovation work for us in 2017 and 2018. The job started as an ensuite remodel. As work progressed to our satisfaction, this workscope continued to expanded to include upstairs remodel, replacing external recladding, then all windows and doors and finally replacing upper and lower decks. Nick was easy to work with and readily amenable and adaptable to the changing workscope. The team were reliable and consistently hard working. Any issues were discussed and dealt with immediately without conflict. The jobs were completed to program, on time, on budget to a pleasing standard.
Helen Rooke, Merewether
Our experience with NJG Constructions was excellent they are very professional and good communicators, always turned up on time and insisted on perfection in all tasks they took on. We are thrilled with the finished product and have no hesitation in recommending them.
John Levey, Merewether
Nick and his team completed a full renovation / extension to our home that we could not be more happy with. Nick was a delight to deal with, could not be more helpful and the whole process was streamline. His team of tradesman were great with the work that they completed A1 standard. They where punctual, polite and always kept the site nice and clean. I could not recommend NJG Constructions enough if you are looking for a building company to use. Thanks again Nick and the team at NJG Constructions.
Ben and Lauren Maybury
Nick and his team were absolutely extraordinary in their efforts in bringing my dream cafe to life. Their attention to detail, reliability, respect and kindness went beyond any expectations, and I couldn’t recommend them highly enough. They made what could have been an overwhelming experience effortless and fun, and the ongoing support after the job was completed was above the call of duty. I am constantly complimented on the fit-out and design of the cafe. I recommend them at every opportunity and can’t imagine ever working with another building team.
Alina, The Cunning Culinarian, Maitland
We have used NJG for two different jobs at our new home in Sydney. One was a partial roof replacement and the other was to re-design one large room into two. They did an excellent job and the work was done in a timely and professional manner. Not only are they friendly and dependable, their expertise and design ideas were top notch, opened up possibilities we hadn’t thought of before. We will use their service again and would highly recommend them to anyone. Thank you Nick and team.
Connie Battista, SydneyCEO
Nick and his team were fantastic. From quote to completion communication was great, the team was friendly and so helpful. During our bathroom renovations we had a isolation period due to illness and Nick and the team were fantastic in rescheduling works and getting the work completed. Finish was great and the bathroom is now a family friendly space for the whole family.
Melissa Ford, New LambtonCEO
Nick and the team were fantastic. On time, good quality work and left the place spotless when they finished. We couldn’t fault them.
Ant Furniss, MerewetherCEO
We have just finished our first of many projects with NJG Constructions and we can highly recommend them. Our project was not large in terms of how big renovations can be, but we were treated as a priority with the utmost professionalism from the entire team. We were thrilled with the attention to detail and the clear pride in their work each team member presented. Each one was respectful, punctual, and thorough. The team functioned well as a unit and you could see clear communication and unity between them, which created a positive environment in our home. We felt they went above and beyond in helping us create what we were looking for, they took the time to effectively problem solve and clearly explain some trickier situations that arose when renovating an older home. We are absolutely thrilled we have found NJG Constructions. We look forward to the next project with them.
Michael & Marie DavidsonCEO
The NJG team were always on time, very responsive to our needs and done a great job. Thanks guys.
Travis KnightCEO
Nick and his team did a great job on our backyard, pool, deck, covered area, garage and guest flat bathroom. Nick was always easy to communicate and handled unplanned variations easily. When some trades did sub par work (which we wouldn't have even noticed) Nick picked it up and redid it himself. We are very pleased with the completed work and would highly recommend NJG for any construction project.
Tony LawderCEO
Nick and his team at NJG were great. Our renovation became much bigger than expected as we found water damage and white ant damage as the initial works were being done. Nick took this in his stride and organised and completed the additional works for us. We are very happy with the end result. Nicks communication was fabulous. Always returned calls and happily answered questions along the way. Highly recommend!
