TJO Contracting LLC

One Merrimack family has hired Tim for four projects — an addition, a deck, a porch repair, then siding and windows — and wrote in May 2026 that they already had the next ones lined up. Another household called TJO one of its core contractors for almost a decade, back in November 2023. A third said in August 2022 that they had used him repeatedly at investment properties and at their own home, and that he stands behind the work. TJO Contracting is Tim's Merrimack, New Hampshire general contracting business — residential construction frame to finish, foundation to roof, run with his own staff plus specialty subcontractors. Angi puts it at eleven years. The range in what customers describe is wide. In November 2025 a family who took multiple quotes to tear down and rebuild their home said TJO came in best, then designed and built the house on time as planned. In March 2024 another described a full gut of a house built in 1900 — walls removed, bathrooms added and moved, floors leveled — as only the first of three phases. A December 2025 review covers a basement renovation; a May 2023 one an attic turned into a home office and an old deck rebuilt as a screened one; a November 2025 one a garage face-lift with new windows and a brow over the door, for which Tim also helped line up a gutter company and an electrician. What customers keep coming back to is the communication. An October 2024 reviewer described constant contact and no surprises on an addition and a new deck, finished on time. A January 2023 customer said Tim kept them in the loop through a large interior and exterior renovation and was flexible when things had to change. Fifteen Google ratings average five stars, and Angi and HomeAdvisor each show 4.9 from nine — the same nine accounts, mirrored across both sites. Those profiles also list an OSI certified installer and a Certainteed master craftsman credential. For a whole-house renovation, an addition, or a new build around Merrimack, this is a contractor whose customers keep coming back for the next job.
