Hiring a grading contractor without checking licenses and insurance is a recipe for liability, cost overruns, and shoddy site prep work. A single accident or incomplete foundation grading can delay your entire project and cost thousands in remediation. Here's exactly what you need to verify before signing a contract.
Why Licensing and Insurance Matter for Grading Work
Grading contractors operate heavy equipment—excavators, dozers, compactors—on your property. If someone gets hurt, equipment damages neighboring structures, or soil work fails to meet code, you could be personally liable unless the contractor carries proper insurance. Licensing requirements vary by state, but they exist to ensure the contractor understands drainage, compaction standards, and local building codes that affect how your project sits for decades.
State and Local Licensing Requirements
Most states require grading contractors to hold an excavation or general contractor license if the job exceeds a certain dollar threshold (typically $500–$2,000, depending on your state). Some states don't require licensing at all—they rely on local city or county permits instead.
Before hiring, check your state's licensing board website. Search for the contractor's name and license number to confirm:
- Current, active status (not expired or suspended)
- Any complaints or disciplinary actions filed against them
- Scope of work they're licensed to perform (some licenses limit project types or sizes)
Don't assume a contractor is licensed just because they claim to be. A legitimate contractor will provide their license number upfront without hesitation.
Required Insurance Coverage for Grading
Grading contractors should carry at minimum:
- General Liability Insurance ($1–2M coverage): Covers bodily injury, property damage, and personal injury claims. Standard for any contractor.
- Workers' Compensation Insurance: Required in all states if they employ staff. Verify coverage limits; typical ranges are $500K–$1M per occurrence.
- Commercial Auto Insurance: Covers trucks and equipment transport to and from your site.
- Equipment Insurance or Inland Marine: Covers owned or rented heavy machinery (excavators, compactors, graders).
Request a Certificate of Insurance (COI) directly from the contractor's insurance agent, not from the contractor themselves. The COI should list your project address and name you as an "additional insured" for at least the duration of work. Most reputable grading contractors have these on file and can email one within 24 hours.
Red Flags to Catch
If a contractor:
- Can't produce a current license or COI within 48 hours: Move on.
- Has a suspended or revoked license: Do not negotiate. This indicates serious past issues.
- Offers dramatically lower rates with "no insurance needed": Their savings now become your risk. If they cause damage or injury, you're liable.
- Won't name you as additional insured on their policy: This is standard practice and should never be an argument.
- Has unresolved complaints on their state licensing board: Check what the complaints were. Minor disputes are normal; patterns of non-payment or poor workmanship are not.
Verify Bonding Requirements
Some states or local jurisdictions require grading contractors to post a surety bond—essentially a guarantee backed by a third party that the contractor will complete work per code and pay subcontractors. Bond amounts for grading typically range from $10K–$50K depending on project scope.
If bonding is required in your area, confirm the contractor has an active bond by asking for proof from their bonding company, not just their word.
Getting Multiple Contractors and Comparing
Don't rely on a single contractor for verification. When you get bids from three or more grading companies, request:
- Copy of their current license (take a photo)
- Current COI with your property listed
- References from similar-sized projects completed in the last two years
- Proof of bonding (if required locally)
This takes an extra 15 minutes per contractor but catches problems before equipment arrives on your site. Platforms like Mercoly help you compare and find trusted Grading & Site Prep providers all in one place, streamlining the vetting process.
Frequently Asked Questions
Q: What should I do if a contractor's insurance lapses mid-project? Stop work immediately and do not allow them back on site until they provide an updated, valid Certificate of Insurance. You remain liable for accidents involving uninsured contractors.
Q: Can a contractor work without a license if the job is under my state's dollar threshold? Possibly, depending on your state, but always verify local city or county permit requirements—some jurisdictions require licensing regardless of project value.
Q: How long should I keep a contractor's license and insurance documents after the project ends? Keep copies for at least three years; some states recommend seven. These protect you if a claim arises after the contractor leaves.
