"Used AJ Perri in past satisfactorily but now... Furnace checkup rattling sound, tech said was due to inducer fan motor needs replacing (ball bearings). Signed agreement for $2,300, they were going to order a replacement, paid $1,175 deposit. Cancelled work before the tech left as we were going to have it done later - also looked up the cost of said motor on the manufacturer web site only $209! Billing department unavailable to have the "pending" charge removed from checking acct. Found cancellation form in paperwork, only includes mailing address with a 3 day only grace period (?). Unable to fax form as a fax # (on a different form only) just rings & rings. Had to scan and email form to general "info" address. Unable to get through to billing dept, never available. Given direct phone # for said dept which gives a recording "voice mailbox not set up" then disconnects. Homeowner fixed all rattling noises for $0 - was only loose screw inside fan motor mounting bracket. Not refunded yet."

Carriere Construction LLC
Carriere Construction LLC
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."
