Hiring the wrong excavating contractor can cost you significantly — not just in rework expenses, but in project delays, permit problems, and damage that affects your property for years. Michigan has specific licensing requirements and environmental regulations that any contractor you hire must understand and comply with. This guide walks you through exactly what to look for, what to ask, and what should be in writing before a machine touches your property.
Why Choosing the Right Excavating Contractor Matters
Excavation is foundational — literally. Whether you’re prepping a building site, installing a drainage system, digging a basement, or clearing and grading raw land, excavation work directly affects everything built on top of it. Unlike painting or landscaping, excavation mistakes often aren’t visible until they cause serious problems: a foundation that settles unevenly, a yard that floods after every rain, or a driveway that cracks within two seasons.
In Southeast Michigan, the additional complexity of clay-heavy soil, extensive regulated wetlands, and drain commissioner oversight makes contractor selection even more important. A contractor who doesn’t know Macomb County’s soil erosion permit process, or who isn’t familiar with Michigan’s wetland rules, can inadvertently expose you to regulatory liability on your own property.
Michigan Licensing Requirements for Excavating Contractors
In Michigan, excavation is a licensed trade. Here’s what the law requires:
Residential excavation work is covered under the Maintenance and Alteration (M&A) Contractor license, issued by the Michigan Department of Licensing and Regulatory Affairs (LARA). Excavation is specifically listed as Trade Code “D” under M&A licensing. Any contractor performing residential excavation for compensation on projects valued over $600 must hold this license.
Commercial excavation is regulated at the local (municipal) level rather than the state level. Requirements vary by city and county.
What this means for you: before hiring any excavating contractor for residential work in Michigan, verify their LARA license. You can do this for free on the LARA license lookup tool at michigan.gov/lara. An unlicensed contractor leaves you with no recourse through the state and, critically, voids your lien rights — meaning you can’t place a lien on your own property if they don’t finish the work or do it improperly.
Penalties for hiring an unlicensed contractor on a residential project can include loss of lien rights on the property. The contractor themselves faces fines of $5,000 to $25,000 and potential jail time for operating without a license.
What to Look for in a Michigan Excavating Contractor
1. Proper Licensing and Insurance
As covered above, verify the LARA M&A license (Trade D) for residential work. In addition, the contractor should carry:
- General liability insurance — minimum $1 million per occurrence; ask for a certificate naming you as an additional insured
- Workers’ compensation insurance — required if they have employees; protects you if a worker is injured on your property
- Commercial auto insurance — covers equipment in transit
Don’t take their word for it. Ask for certificates directly from their insurance provider, not a copy they hand you.
2. Relevant Local Experience
Michigan-specific knowledge matters. Ask whether they’ve worked in your county before and whether they’re familiar with:
- Your county drain commissioner’s permit requirements
- Michigan EGLE wetland permit processes (if your property is near water)
- MISS DIG (811) procedures and local utility layouts
- Soil conditions typical to your area (southeast Michigan’s clay-heavy glacial till behaves differently than sandy soils in other parts of the state)
3. References and Track Record
Ask for references from projects similar in scope and type to yours — not just any past customer. A contractor with a strong track record on basement excavations may have little experience with multi-acre site clearing. Make sure the references are relevant.
Online reviews (Google, Better Business Bureau) are a reasonable starting point, but direct references let you ask specific questions: Did they show up on schedule? Were there surprise costs? How did they handle unexpected issues?
4. Equipment Capability
The right contractor should have — or have reliable access to — the right equipment for your project. A small skid steer operator who typically does landscaping may not be equipped to handle a multi-acre clearing and grading job requiring an excavator, bulldozer, and dump trucks. Ask specifically what equipment will be used and whether it’s owned or rented.
5. Clear Communication
You want a contractor who explains what they’re doing, why, and what to expect — not one who gives you a vague estimate and asks you to trust them. If they can’t clearly explain the scope of work during the estimate process, that’s a signal of how communication will go throughout the project.
Questions to Ask Before Hiring
Before signing any contract, get answers to these questions:
About licensing and insurance:
- Can you provide your LARA M&A license number so I can verify it?
- Can I get certificates of insurance for general liability and workers’ comp?
About the project:
- Have you done similar projects in this county before?
- Are permits required for this project, and if so, who pulls them — you or me?
- Will you call MISS DIG before excavation begins?
- How will you handle unexpected issues — buried debris, unexpected rock, or soil conditions different from what you expect?
About the quote:
- Is this a fixed price or an estimate? Under what conditions could the price change?
- What exactly is included — and what isn’t?
- How is debris disposal handled, and is it included in the price?
- What are your payment terms?
About the timeline:
- What is the expected start date and completion date?
- What factors could delay the project?
- How many other projects will you be running concurrently?
Red Flags to Watch For
No LARA license or reluctance to provide license number. Walk away. There is no legitimate reason a licensed Michigan excavating contractor won’t provide their license number.
Significantly lower bid than everyone else. Excavation has real costs: fuel, equipment, labor, disposal. A bid that’s 40% cheaper than competitors usually means something is being left out — disposal, permits, insurance, or stump removal — or the contractor plans to cut corners.
Cash-only payment requirement. Legitimate contractors accept checks or standard payment methods and provide written contracts. Cash-only arrangements make it harder to pursue remedies if something goes wrong.
Pressure to start immediately without a written contract. A verbal agreement protects neither party. Any reputable contractor will put the scope of work, price, timeline, and payment terms in writing.
No mention of MISS DIG. Before breaking ground anywhere in Michigan, underground utilities must be marked. A contractor who doesn’t bring this up has either skipped this step before or doesn’t know it’s required.
Vague scope of work. “Clear the back lot and grade it” is not a contract. A professional contract specifies exactly what’s being cleared, how debris will be disposed of, what grading means in terms of final elevation, what equipment will be used, and what isn’t included.
What a Proper Quote Should Include
A detailed, written quote from a Michigan excavating contractor should cover:
- Project address and scope — specific description of what work will be done
- Materials included — fill dirt, topsoil, gravel, etc., with quantities where known
- Equipment to be used — excavator, bulldozer, dump trucks, etc.
- Debris disposal plan — how removed material leaves your site
- Permit responsibility — who obtains required permits (Part 91, EGLE, etc.)
- MISS DIG — confirmation that underground utilities will be marked before work begins
- Timeline — estimated start and completion dates, and what could change them
- Payment terms — deposit amount, milestone payments if applicable, final payment trigger
- Exclusions — what the quote does NOT include (often: rock removal, unexpected buried debris, soil import/export beyond a certain volume)
- Warranty or guarantee — what happens if the finished work doesn’t meet spec
A quote missing most of these items isn’t a professional quote — it’s a guess written on paper. Push for specifics before signing.

Frequently Asked Questions
Do excavating contractors in Michigan need to be licensed?
Yes. In Michigan, excavation is a licensed trade under the Maintenance and Alteration (M&A) Contractor license issued by LARA (Trade Code D). This applies to residential excavation projects valued over $600. You can verify any contractor’s license on the LARA website at no cost.
What insurance should an excavating contractor have in Michigan?
At minimum, general liability insurance (typically $1 million per occurrence), workers’ compensation (if they have employees), and commercial auto insurance. Ask for certificates of insurance before work begins — not copies the contractor prints, but certificates issued directly by the insurance provider.
What questions should I ask an excavating contractor before hiring?
Ask for their LARA license number, certificates of insurance, local project references, whether permits are required (and who pulls them), how they handle unexpected site conditions, and for a detailed written quote that specifies scope, disposal, timeline, and payment terms.
What are red flags when hiring an excavating contractor?
Key red flags include: unwillingness to provide a LARA license number, bids significantly lower than competitors without explanation, cash-only payment requirements, pressure to start without a written contract, and no mention of MISS DIG (811) for utility marking.
What should an excavating contractor quote include?
A professional quote should detail the scope of work, materials, equipment, debris disposal plan, permit responsibility, MISS DIG compliance, timeline, payment terms, and specific exclusions. Vague quotes without line-item detail are a warning sign.
