Optimum Building Systems Inc

Optimum Building Systems is a family-owned commercial specialty contractor headquartered in Litchfield, New Hampshire, and says it has operated since 1990 under brothers Rene and Sylvain Theroux. Its own site focuses on commercial drywall and metal framing, waterproofing and vapor barriers, acoustical ceiling tile, cladding, trusses and related construction specialties; it also presents Wall Works Holdings as its network umbrella. The three Google reviews available, dated 2021–2023, are positive but very small and mostly brief. A 2022 reviewer praised professionalism, competitive pricing and follow-through; another 2021 entry describes a delivery rather than a completed project, so this record is not a deep customer-performance history. Before booking, ask for recent comparable commercial-project references, confirm whether OBS takes your project type and scope, and clarify which services are performed directly. The site claims an RI OSC registration number, but that registration was not independently verified here; the review record is also dated, with no comments from the last six months.
