If you're planning a home addition, a new driveway, or even grading work in your yard, you’ll probably need to dig near trees. It may seem simple, but working too close to tree roots can lead to costly, long-term problems. Damaging a tree’s root system doesn’t just put that tree at risk. It can create safety hazards, property damage, and even legal trouble if the tree borders another property.
Whether you're in Hunterdon, Somerset, or Mercer County, Long Hill Contracting helps homeowners manage excavation projects safely—without compromising the health of your landscape.
Why Tree Roots Matter More Than You Think
Most trees don’t have deep taproots. Instead, they rely on wide, shallow root systems that can stretch two to three times the tree’s height. These roots anchor the tree, absorb water, and provide nutrients. Cutting or disturbing them can destabilize the tree and shorten its lifespan.
Here’s what to keep in mind:
- Even minor root loss can stress a tree
- Large root cuts near the trunk can cause instability
- Soil compaction from heavy machinery can suffocate roots
For mature or valuable trees, root damage may not show right away, but decline can happen months or even years later.
Why Excavating Near Tree Roots Requires Expert Oversight
Most homeowners aren’t aware of how wide or shallow tree root systems actually are. Even experienced landscapers can misjudge the impact of digging too close. That’s why excavation near trees should always be handled by professionals who understand both soil structure and root behavior.
Working closer than that increases the risk of:
- Tree death or decline
- Leaning or uprooting in storms
- Fungal infections through open root wounds
- Fines or neighborhood disputes (in some NJ towns, trees are protected by ordinance)
Planning a Project? Start With a Site Assessment

How Long Hill Contracting Protects Your Trees During Excavation
Our team uses proven strategies, like air spading, root pruning, and boring under roots, to complete excavation projects without compromising tree health. These techniques aren’t typically available through basic equipment rentals or general contractors. They require trained crews who know how to spot potential issues before they turn into real damage.
- Air spading: Gently exposes roots using compressed air, not shovels
- Root pruning: Cleanly cuts roots in advance to avoid ragged damage from machines
- Boring under roots: Allows for utility installation or drainpipes without cutting roots
- Protective matting: Prevents compaction from heavy equipment
Notably, these techniques are especially useful in older neighborhoods like Flemington, Hopewell, or Clinton, where trees are mature and often irreplaceable.
Can a Tree Be Saved After Damage?
Sometimes, yes. If roots have already been damaged, early intervention helps. A certified arborist may recommend:
- Soil aeration
- Mulching to retain moisture
- Fungal treatment
- Cabling or support systems
The key is fast, informed action. And in many cases, that starts with a contractor who notices the signs during excavation.
Before Any Digging Starts, Here’s What Our Experts Evaluate
