Owner-led, Hiawassee-based, and 25+ years in the ground.
ALC Underground is Shawn Gallagher’s crew. Shawn has spent more than 25 years getting land ready and putting septic and site work in the ground across the North Georgia mountains — and he’s a certified septic installer in both Georgia and North Carolina. This is what he does.
We kept it simple on purpose. You call, you get Shawn. We look at your job, tell you what we honestly see, and walk you through the next step in plain words. No jargon. No pressure.
We are local. We live and work around Hiawassee, and we treat your land like it is down the road from ours — because it usually is. Good work starts below ground.

We talk like a neighbor, because we are one.
We show the work, not the hype.
Clear answers. Clear next steps.




Call or text and we will walk you through it. No pressure, no runaround.
