Why homeowners pick Tri-County

Built for Delaware weather, finished to last

811 Before Every Dig

We call Miss Utility before the bucket goes in the ground. It is a safety requirement and the only responsible way to excavate.

Owned Equipment

Excavator and skid steer on our own books keeps the workflow controlled. You are not waiting on a rental operator to fit the job into someone else’s schedule.

Grading & Drainage Done Right

We grade for positive drainage so water moves away from your home, driveway, and usable yard — the single most common reason homeowners call us for site work.

Standalone or Concrete-Ready

Hire us for excavation only, or bundle it with a concrete pour so one crew owns both the ground and the slab that follows.

Details

Delaware excavation and site work done right — for your project or your crew.

Tri-County Construction is a Delaware excavation contractor handling dirt work and site preparation across New Castle County and the surrounding area. That includes land clearing, tree and stump removal, excavation for foundations, footings, additions, and pools, utility trenching for water, electric, and sewer, site grading, grading for drainage, fill, and general site prep — whether you are clearing a lot, running service to an outbuilding, or getting ground ready for the next phase of construction.

Homeowners usually call us with a practical problem: a backyard that floods after every storm, a lot that has to be graded before a build, a spot that needs digging for a pool or an addition, or a soft, low area that never drains. We diagnose where the water is going, set grades that move it away from the house and usable space, and leave the yard ready to use — not just disturbed.

A large share of our excavation work is also for other local contractors. Electricians, plumbers, and builders bring us in to trench for electrical, plumbing, and water lines, grade a site, or move dirt so their own crews can stay on the skilled trade. We show up with owned excavator and skid steer equipment, so scheduling stays on our clock, not a rental operator’s.

Miss Utility / 811 is called before every dig — no exceptions. We do not put a bucket in the ground until locates are flagged. On drainage and grading jobs we set positive pitch away from structures, and on foundation and pool digs we hold the depth and dimensions the next trade needs. Final grade is documented with photos so the next crew or the property owner has a clear record of exactly what was completed.

We do not quote dirt work with a blind per-yard number over the phone, because access, soil type (clay, sand, or rock), depth, and haul distance change the real price on every job. Instead, every project starts with a free on-site walk and a written estimate — so you know the scope and the number before any equipment shows up. Call (302) 419-3232 to get on the schedule.

FAQ

Common questions

Don't see your question? Call (302) 419-3232 or send a quick note through the contact form — we usually reply same-day.

Do you offer excavation near me in New Castle County?
Yes. Tri-County is based in New Castle County and serves homeowners, builders, and contractors across Delaware. Call (302) 419-3232 and we will schedule a free on-site walk, usually within a few days.
How much does excavation cost in Delaware?
It depends on how much material is moved, soil type (clay, sand, or rock), site access for equipment, depth, and haul distance. We price after a site walk instead of guessing per yard over the phone, and every estimate is free.
Do you clear land and remove trees or stumps?
Yes. Land clearing, brush removal, tree and stump removal, and general lot clearing are part of our site-work scope, on their own or ahead of a build.
Do you handle grading and drainage for a yard that floods?
Yes — it is one of the most common reasons homeowners call. We regrade for positive drainage so water moves away from the house and usable yard instead of ponding or running toward a neighbor.
Can you do excavation only, with no concrete?
Yes. Site prep is a standalone service, and many builders bring us in early to grade, trench, and prep before another trade takes over.
Do you call Miss Utility / 811 before digging?
Always. We will not put a bucket in the ground until 811 is called and utility locates are flagged. It is the safe, legal, non-negotiable way to excavate.
