Verified record
Karatzas Contracting is a small, Tim Karatzas–led design-build outfit that's been working out of Merrimac since 2011, per the Better Business Bureau, which lists it A+ (unaccredited) with 4 employees. Its own site describes handling residential and commercial construction from concept through occupancy, and it turns up in local Reddit recommendations for general-contracting work on the North Shore. The written record is thin but dated, not absent: BuildZoom's permit history shows 16 permitted projects, mostly residential remodels in Merrimac, Newburyport and nearby towns, and a single detailed review from 2017 described the company finishing a project on time and on budget, with progress photos along the way, calling the experience good enough to spoil the reviewer for every other contractor since. Massachusetts' registry shows the company's home improvement contractor registration, #153683, as expired. BuildZoom's own listing separately shows a different HIC number, #182073, as active, along with an active construction supervisor license — those are the directory's claims, not something verified against the state. Worth confirming current licensing directly before signing anything, but the permit history and the one detailed account point to real, completed residential work.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Karatzas Contracting Co. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$23,000 – $35,000
Typical remodeling project around $29,000

I would recommend Tim a million times!!! He finished everything on time and sent me photos of everything that was completed and his work was excellent. I gave him a budget and a time line. He NEVER wavered from either! I can't believe that he was my first experience with a contractor. He has spoiled it for everyone else. I highly recommend him!!!
