J&J Contracting Corp

J&J Contracting Corp is a masonry and hardscape company in Middleton, working across Eastern Massachusetts and into southern New Hampshire, with landscape construction as part of the same job. Gustavo Maradiaga founded it in 2018 and runs it himself; by the company's account he spent more than 15 years in hardscape and masonry sales and design-build work at other firms before starting his own. Its Massachusetts home improvement contractor registration, #203353, is active. The company also cites ICPI and NCMA training — the paving and concrete-masonry side of the trade. A founder-run shop this size is the right call when you want the person who quoted the job on site while it is built. Ask to see masonry and hardscape they have finished nearby, confirm insurance, and get the materials and the scope in writing before the stone is ordered.
