Excavation Services in Annapolis, MD
Some plumbing lives under the ground, and when it fails the repair means opening it. Heidler has been digging in Anne Arundel County soil for 79 years — and we find the fault before we break ground, so the hole stays as small as the job allows.
Call (410) 268-7191Every Excavation Service We Handle
We're licensed plumbers who excavate for our own work — sewer laterals, water service lines, buried gas runs, and drain lines. That's a deliberate boundary: we don't take on grading, site work, or utility trenching outside plumbing, and we'll tell you when a job belongs to a different trade rather than approximating it.

The expensive mistakes in excavation happen before the machine arrives — digging on a guess, skipping the utility notification, or backfilling carelessly so the ground settles a season later. This is the order we work in, on every job.
We Locate Before We Excavate
Camera inspection and locating establish what failed, where it sits, and how deep. That's the difference between one targeted hole and a trench across your yard.
Notification and Permits First
Maryland requires a Miss Utility ticket at least two full business days before excavation. Work reaching the county right-of-way needs its own permit. We handle both.
Backfilled to Hold Grade
Compacted lifts rather than a shovel-and-go refill, so the ground doesn't sink over the line the first wet winter after we leave.
Tested and Inspected
Buried work is verified before it's covered — pressure-tested, inspected where the county requires it, and signed off while anyone can still see it.
Before You Dig, Rule Out Digging
Excavation should be the answer to a question somebody has actually asked. These are the pages that decide whether your line needs opening at all — start here, and if the camera says the pipe can be lined or burst instead, you keep your lawn.

- Do I actually need excavation, or can it be done trenchless?
- The camera decides. Trenchless lining needs a host pipe with enough structure left to line, and pipe bursting needs a path the new pipe can follow. A collapsed section, a severe belly holding water, or badly offset joints take those options away. We inspect first and tell you which category you're in — we offer both, so we've no reason to sell you a dig you don't need.
- How soon can you dig?
- For planned work, the schedule is set by the Miss Utility notification window — at least two full business days before excavation begins, so utility owners can mark their lines — plus permitting. For genuine emergencies there's a separate path with a two-hour utility response, which is what emergency excavation runs on.
- What happens to my yard, driveway, or parking lot?
- We size the opening to the repair and know from the locate what the route crosses before we start. Where it crosses hardscape, that's usually the point where a trenchless or pulled-in method becomes worth comparing, because restoring concrete or brick often costs more than the difference in method. Restoration is quoted up front either way.
- Are you an excavation contractor?
- We're licensed plumbers who excavate for our own work — sewer laterals, water service lines, buried gas runs, and drain lines. We don't take on site work, grading, or non-plumbing utility trenching, and we'll point you to the right trade when that's what a job actually needs.
- Do you handle commercial properties?
- Yes. Commercial excavation is scheduled around your operating hours, with camera diagnosis, documentation for owners and property managers, and asphalt or concrete restoration priced before the work starts.
Where We Dig
We excavate across Annapolis and Anne Arundel County — including the older neighborhoods where clay and cast iron laterals are still in the ground, and the waterfront areas where a high water table makes every trench its own problem. See every area we cover.
