DIY vs. Professional Excavation, Demolition & Land Clearing in Delaware
Should You DIY It or Call a Professional?
Some small jobs around a property are fine to handle yourself: a garden bed, a few saplings, a small shed taken apart with hand tools. For a homeowner without experience running equipment or doing site work, excavation, structural demolition, and land clearing are a different kind of job. They can involve heavy equipment, buried utilities, and rules that change with the county, the town, and the property.
When a do-it-yourself site project runs into trouble, it is often because of things a homeowner has no reason to know yet: which office to call, what has to be disconnected first, what is in the walls, and where the debris can legally go.
This page walks through those questions for each type of work, and explains what an experienced contractor handles as part of the job. It is written for homeowners and property owners with little or no site-work experience. Every property and project is different, so treat these as questions to ask, not rules that apply to every job. Interior demolition is a different scope, and commercial projects can have additional requirements.

Three Questions Every Site Project Raises
​Which rules apply to this property? Permits, inspections, utility disconnects, and environmental rules vary by county, by town, and by the scope of the work. Some projects need paperwork filed weeks ahead. Others need none. The hard part is knowing which is which before work starts.
​
What is underground, and what is in the structure? Digging and demolition both carry the risk of hitting a line nobody marked. Older structures can also contain asbestos, which has to be dealt with before a building comes down.
​
Who is responsible if something goes wrong? If a utility line, a septic system, or a neighbor's property is damaged, responsibility depends on the circumstances: who owns the line, whether it was marked, what any contract says, and what happened. That is worth understanding before work starts, not after.
Here is how those questions play out for each kind of project.
Excavation: Why It Is Rarely a DIY Job
Hand digging a garden bed or a shallow trench for a downspout is reasonable homeowner work. A foundation, a building pad, a driveway base, or drainage grading is a different task. It depends on reading soil, setting grade, and moving water away from structures correctly the first time.
The machine is only part of the cost. Transport, fuel, stone, and disposal all add to a rental, and the work usually takes a first-time operator much longer than it takes an experienced one.
Call 811 first. Delaware law requires notice to 811 at least 3 business days, and no more than 12, before excavation begins (26 Del. C. § 806, reviewed October 2026). It is free, and it applies to homeowners as well as contractors.
Site rules depend on the project. Larger land disturbances can require an erosion and sediment control plan, and other approvals can apply depending on the work.
When we take on an excavation, working out which of these apply is part of performing the project.
Demolition: Why Structural Demolition Belongs
With a Professional
A small shed that comes apart with hand tools is one thing. Taking down a house, a garage, or part of a structure is another. The demolition itself is often the shortest part of the job. The planning around it is where many projects run into trouble.
​
Requirements depend on where the property is. Whether a demolition needs a county permit, a town permit, both, or neither depends on the county, the municipality, and the structure. Our guide to Delaware demolition permits explains how the three counties differ.
​
Asbestos comes first. Structures built before the 1980s can contain asbestos in siding, roofing, flooring, or insulation. It should be identified by a licensed inspector and, where it is found, removed by a qualified abatement contractor before the structure comes down. Asbestos is a serious health hazard, and it is not a do-it-yourself task.
Utilities have to be disconnected the right way. Electric, gas, water, sewer, and any buried fuel tank each have their own shutoff or removal process. Delaware's 811 law covers demolition as well as digging.
Debris has to be contained and removed. How a structure is taken down decides what is left in the ground afterward. We use deliberate methods to keep debris contained and remove it thoroughly, which reduces the risk of glass, paint chips, and other debris being ground into the soil.
When we take on a demolition, we work out which requirements apply to your property and whom to contact, and we coordinate with asbestos inspection and abatement providers. That guidance comes with doing the job.
Land Clearing: Why Rented Equipment Is Not the Shortcut It Looks Like
Trimming brush and cutting a few small saplings by hand is homeowner work. Clearing a lot is a bigger job. Felling trees and running a skid steer or a forestry mulcher takes training, and a mistake with either one can injure the operator or damage the property next door.
Mulching does not remove stumps. Root systems left in the ground can interfere with foundations and drainage later. If you are clearing to build, stump removal is its own step.
You cannot burn the debris. Delaware's open burning rules prohibit burning material from land clearing, except for agriculture, and most open burning is banned from May 1 through September 30 (DNREC, reviewed October 2026). Whatever comes down has to be chipped, hauled, or disposed of properly.
Clearing can trigger site rules. Property size, wetlands, and waterways all affect what is allowed and what has to be filed first.
We offer both stump grinding and full stump removal, depending on what your project needs.
