Construction Acquisitions in New Hampshire
New Hampshire Construction Deal Highlights
In New Hampshire construction, recent deal activity centers on platform building and add-on expansion across specialized trades and service delivery. Buyers such as Wall Works Holdings (backed by AVALT and VantEdge) and Groundworks are using acquisitions to deepen capabilities and widen geographic reach in New England.
Several transactions also reflect specialty contracting and service scaling. Optimum Building Systems, LLC expanded through the acquisition of C.I.D. Construction, Inc., while Trivest Partners and Canopy Services launched a residential roofing and gutter platform with Adam Vaillancourt Roofing. Other activity includes growth investment in restoration services by Summit Partners and water/wastewater contractor expansion via MWH Constructors, Inc.
What Stands Out
- Wall Works Holdings is building a New England platform with Optimum Building Systems as a hub, including an add-on acquisition of C.I.D. Construction, Inc.
- Groundworks entered New Hampshire for the first time through the acquisition of Rescon Basement Solutions in Hooksett; the acquired team continues under the Groundworks name.
- Residential roofing and gutters appear as a platform theme: Trivest Partners launched Canopy Services after acquiring Adam Vaillancourt Roofing.
- Property restoration services in Portsmouth drew growth equity from Summit Partners, with plans that include expansion and a buy-and-build approach.
- Water/wastewater construction is represented by MWH Constructors, Inc., which acquired Methuen Construction Company and planned to keep Methuen operating as a separate entity.
