Highlights
- Established since 2008 — long-running commercial concrete subcontractor
- Commercial-only scope — works for general contractors on commercial projects, not homeowners
- Trucking safety record — federal carrier data shows below-average safety scores
- Reported unsafe driving — a 2026 review described trucks nearly causing a road incident
MPC Construction LLC is a commercial concrete flatwork subcontractor founded in 2008 by Corwin Muhonen, based in Jaffrey, NH. The company's own site describes it as working for general contractors on commercial and industrial slabs, sidewalks, exterior paving and stamped concrete across New Hampshire, Massachusetts and southern Maine — it presents itself as a subcontractor to builders, not a homeowner-facing service. Recent project posts from a company project manager describe commercial jobs including a training center in Alfred, ME in 2025, a retail dealership slab in Concord, NH, and foundation work for a condo development and ski patrol headquarters in North Conway, NH. Two Google reviews are on file: a detailed 2026 complaint describing the company's trucks nearly forcing a family off the road, and a brief five-star review calling the work 'beautiful.' A public federal motor-carrier safety database also shows the company's trucking operation scoring worse than most carriers on several inspection categories. Because this business works commercially for general contractors rather than directly for homeowners, no services are listed here.
