Located in Hudson County, NJ and founded in 2012; Carriere Construction is a modest group of construction professionals that provides construction services in all phases of interior construction. Our goal on every project is to provide high quality building services efficiently, and tailored specifically to the consumer. We achieve this by making client communication and hard work our highest priorities. This approach has built us a growing list of satisfied customers that we are very proud of.

"Sean and his crew renovated my condo after a flood damage in early January. This is our first remodel project and prior to working with a contractor, we've heard pretty negative stories about GCs in general. And to our surprise, Sean was the exact opposite of what we've heard. Communication - I would rate myself as a very responsive person and because the remodel happened after a flood damage, I was quite in an urgent situation and was eager to get the project finished. Sean communicated with us in a very timely manner and on many occasions, live - as they perform a specific task within the unit. He responds to my texts throughout the night on matters and feedbacks I provided (re: inspection at end of day on a daily basis). Project timeline - we finished the entire project (lighting, kitchen, drywall repair, painting, floor installation, room re-arrangement, door/trim, baseboards, everything but tiles in the bathroom) within 5 weeks (which was my target). While there are glitches during the project, Sean was very honest and frank about the project and always communicated about the progress and delays if any. He arranged the day-to-day work appropriately so it uses the best of his crews' time and meet our deadline at the same time. Quality of Work - i can't complain about the integrity that goes to the work. Sean will be sure to modify and change anything that I expect, and if he doesn't, he would make sure he explains it so I can accept the reasons behind them. That's very important to me as a client. Even after the project ended, when we saw the need for minor fixes after we moved back in, Sean stopped by on several occasions to fix those things. Pricing - Sean's quote was very reasonable and he provided an extremely detailed breakdown of the costs (materials and labor). We know what we are getting, and it was this level of transparency that ultimately led us to hire him for the job. During the project, he provided receipts and if there are any incremental costs not foreseen before, he'd communicate that prior to purchasing. In the end, we spent maybe just a little over $1k more than the quote (which is VERY GOOD) compared to many stories I've heard. He even assisted in providing information to my insurance company for the claim, and was very happy to do it. Overall, I think he's professional and certainly added an extremely positive reputation to his industry. I would certainly work with him again in the future and have already recommended him to several neighbors."

FAQs for second story addition building service projects in Mahwah, NJ

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
