New Septic Installs — Built to Your Engineer's Plan
Dunbar Construction installs septic systems for homeowners and builders throughout Littleton, Houlton, and Mars Hill, ME. We work straight from your engineer's design — excavating the site, setting the tank, running the lines, and backfilling so the system is in spec and ready for inspection on the first pass.
New build, replacement, or a system that needs to be upgraded before you close on a house — we handle all of it, and we've installed just about every tank type and configuration in our 40+ years working Aroostook County. Call (207) 694-0540 or reach out here to get on the schedule.
Drainage Work to Keep Your Property Dry
Poor drainage is behind a surprising number of the jobs we get called back to fix. Water runs where it wants unless someone tells it otherwise, and in this part of Maine, that means frost heaves, flooded basements, and septic fields that stop absorbing. We install the drainage work that prevents all of that — perimeter drains, swales, culverts, storm lines, and surface grading that carries water away from the places it shouldn't be.
Whether your drainage problem is on a rural lot outside Littleton or a commercial property in Houlton or Mars Hill, we'll come out, walk it, and tell you what it actually needs — not what's easiest for us to sell.
Diagnostic Dig-Outs When Something's Wrong
When a septic system stops working the way it should, step one is figuring out what's going on underground. We'll excavate the system carefully, work with your inspector or plumber to track down the problem, and — if you need a replacement tank, new lines, or updated drainage — we can handle that work in the same visit.
