Marsh X Development is the kind of Dunstable contractor people call when a property needs serious ground work: excavation, demolition, drainage, retaining walls, and outdoor construction. The company says Andrew Marsh founded it in 2009, that it is family-owned and operated, and that it serves residential and commercial clients across Middlesex and Essex counties in Massachusetts and Hillsborough County, New Hampshire. Its Massachusetts home improvement contractor license is registry-verified active.
The written customer history runs from 2022 through 2024, with every quoted Google rating at five stars and repeated praise for difficult site work. In a 2024 review, a homeowner described a backyard pool and retaining-wall project after Andrew talked through options and their tradeoffs. Another 2024 customer said an earlier pool fill-in and landscaping project had held up beautifully, then hired the crew again to replace a concrete retaining wall and stairs. Reviews from 2023 describe stump clearing, grading, playground-mulch installation, retaining walls on a steep muddy hill, and demolition and foundation excavation for a new home. Customers also mention prompt quoting, clear explanations, staying on schedule, and returning for additional work.
The scope is broad, but the strongest pattern is hands-on site preparation and landscape construction. The company website lists excavation, drainage, septic installation, and outdoor-living and hardscaping construction; customer accounts add demolition, grading, stump clearing, pool work, retaining walls, and foundation preparation. Procore lists concrete, earthwork, excavation and fill, grading, site clearing, demolition, and several retaining-wall categories.
Marsh X looks suited to homeowners and builders planning a substantial property or site project rather than a small repair. Before booking, confirm the exact scope, drainage or septic requirements, and the schedule for a multi-stage job, then ask for a written proposal that spells out excavation, disposal, materials, and any retaining-wall or hardscaping work.
