"We had the most wonderful experience with this company. We desperately wanted our basement finished before the arrival of our second child. Misael got it finished even faster than we anticipated. We couldn’t be happier with how it came out. The price was exactly what was discussed (no hidden costs in the end). We would hire him in again in a heartbeat to do any home renovations."

"From the day we hired Nicopal for bathroom remodel to the day they finished the project everything was smooth and super! Vincent was one of the best contractor we hired for bath remodel. Reasonably priced, fabulous work by his team (Jaime & others). We did 2.5bath renovation out of which the master bath was a remodel too. All of them look amazing and inviting! Would definitely recommend Nicopal Constructions for any bathroom projects."

"BelMax did several projects for me including two major projects; (1) remodeling a basement bathroom with the addition of a shower and adding a second-floor addition to the house which became a walk-in closet. BelMax worked with an architect to get a solid design, pulled the permits, completed the work, and got the work approved. I am very pleased with the quality of their work. Throughout the job, the crew wore masks and shoe coverings when they worked inside, which I appreciated. They were also very clear about what was budgeted for each minor project so that later when we changed some of the requirements, we were able to work together to figure out the change in cost. Please note that some of the changes in scope were required. For example, after prior to the work stating, the architect said that we had to add another bedroom window to the house to meet city code. I recommend them and would consider them for work at my house in the future."

"I have known Bill since 2005. At that time he built an addition of a bedroom suite and bathroom to our new home. Since then he has answered our calls for projects small and large. Among the things he and his crews have done are a kitchen remodel, new flooring, master bedroom suite addition, deck, siding, finished the basement, and a garage with a 2 story building attached with the first floor a dance studio and upstairs a game room. Bill is always responsive and listens to what the customer wants. He has always provided me with top notch service."

"Had to reschedule my original appointment due to their late arrival for the first scheduled time. The office admin was helpful in taking care of that. Once they did arrive on a later date, the work was done quickly, efficiently and of high-quality. I will consider them for an additional project in the future."

Customers say: Super punctual

"This is an overdue review. I hired Bernie and his team for a kitchen remodel in June 2021, after he did an excellent job with my three bathrooms in 2020. The kitchen remodel was also excellent. His works are efficient, hardworking and clean. My remodel took two weeks, as he had quoted and for the exact price he had quoted. I would hire him and his team again and I referred them to a coworker for her bathroom project. She was also very pleased with their work."

"They did a great job on a bathroom remodel. Attention to detail, knowledgeable and efficient. They did a beautiful job on the tile and granite and glass door installation and they even helped me save and refinish an old oak vanity and mirror. Highly recommend."

"I am a Realtor and also remodel houses for a living. For the second time now, Peter Burley, CEO, and the NJSA Team helped me reorganize an unpleasant and awkward house, which was cramped and dysfunctional and went unsold for years. Once again, being able to open the home to a highly-efficient, fully-integrated sunroom allowed us to effectively turn the house around, with all spaces leading to this beautiful gathering room, that embraces the patio and private backyard. The addition reinvented the flow and function of the house, and extending the kitchen into the greatroom allowed in turn the sunlight to flood the home. Visitors and fellow Realtors express their delight in how an otherwise pretty ordinary house can be truly transformed into this fully-enjoyable home. NJSA also did a gorgeous job in refinishing the second floor with an expansive apartment and gracious master bath, tucked into a new dormer. Being able to rely upon a single builder - with over 30 years experience and such high standards and work ethics - to remodel from the studs and replace all systems, utilities, roof, windows... is quite an advantage. Being able to hire the exclusive area designer and installer of the industry-leading LivingSpace and K2 products is a privilege indeed. NJSA stays on the job, non-stop until completion, and stands out for respecting its quotes, budget and deadlines. And yet, Andy Chief of Operations, and his tradesmen will solve every problem they encounter - not I ;-) - and will do so as a matter of course, seemingly effortlessly, alleviating all conflicts and stress usually associated with remodeling a home. Dedicated members of the NJSA team will also develop a smooth and respectful relationship with the building department: thanks to this, I had a certificate of completion barely 4 months after I closed on the property. As the project progresses, the praise and trust of the inspectors grows with every inspection: such rapport greatly affects the outcome and is most beneficial to my business. Time and again, NJSA's prices for a job done right are competitive, and their reputation and the quality of their workmanship are selling points when it is time to put the property on the market. Feel free to visit: http://www.njmls.com/listings/index.cfm?action=dsp.info&mlsnum=1637778&openhouse=true&dayssince=&countysearch=false Peter, Andy and every single craftsman on your team: it was a real pleasure working with you again."

FAQs for addition and remodeling projects in Hillsborough, NJ

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
