Excavation Contractor & Site Developer
Dunbar Construction has spent most of the last 40+ years running excavators across Aroostook County, so when homeowners and builders in Littleton, Houlton, and Mars Hill need dirt moved, we're usually the first call. From a single-afternoon trench to a multi-week commercial site development, we've got the iron and the crew to get it done — and priced so it makes sense.

Site Development From Raw Land to Ready-to-Build
When a commercial or residential build needs a full development package — clearing, rough grade, drainage, utilities, and final pad — we take it all on as one job. That means fewer crews on site, fewer invoices, and a single point of contact from first cut to handoff. Whether the lot is in Littleton, Houlton, or Mars Hill, we'll walk it with you, tell you what it needs, and quote it straight.
