What to check before hiring an excavation contractor in Jacksonville, FL
Eight checks, none requiring an expert, all free. Run them on every crew you talk to, including us. The whole list takes under an hour and it filters out most of what goes wrong on dirt jobs.
1. Active state registration
Why it matters: A company that dissolved last year can’t stand behind this year’s work.
How to check: Search the exact business name on Sunbiz, Florida’s corporate registry. Active status, and note how many years it goes back.
2. Insurance certificate from the agent
Why it matters: A photocopy proves a policy existed once. Excavation drops machines next to houses and gas lines.
How to check: Ask for a certificate of insurance emailed directly by their insurance agent, naming you or your address. Takes the agent five minutes.
3. State license, when utilities are involved
Why it matters: Tying into water, sewer or storm systems is a licensed trade in Florida. General dirt work is not, so this check applies only when pipes connect.
How to check: Look up "underground utility and excavation contractor" for the company on the DBPR license search.
4. Who files the 811 locate
Why it matters: Sunshine 811 marks buried utilities free of charge, two business days before a dig. Digging without it is illegal and how gas lines get hit.
How to check: Ask "who calls 811 and when?" The only good answer: "we do, every job." Hesitation here ends the conversation.
5. A water plan for your parcel
Why it matters: Much of the First Coast sits a few feet above groundwater. Deep digs may need dewatering ($1,200 to $4,500) and wet season work may need matting or a schedule shift.
How to check: Ask what happens if the trench hits water. You want a priced line item and a method, not "shouldn’t be a problem."
6. A written spoil and debris plan
Why it matters: Haul-off at $150 to $350 per truckload is where vague quotes grow. Cleared vegetation and dug spoil have to go somewhere.
How to check: The quote should say spread on site, mulch in place, or haul with an estimated truckload count.
7. Sane deposit and payment terms
Why it matters: Machinery-heavy work has real mobilization costs, but a contractor demanding half the job in cash upfront is financing their last job with yours.
How to check: Reasonable: a modest mobilization deposit, balance on completion, milestones on bigger jobs. Get the schedule in the contract.
8. Wildlife and wetland awareness
Why it matters: Gopher tortoise burrows stop Florida jobs legally and immediately, and parcels touching mapped wetlands can need city or St. Johns River Water Management District review before machines.
How to check: Ask what happens if they find a burrow. A crew that says "we work around it quietly" is volunteering you for the fine.
One more filter: can you check their math?
The checklist above tells you a contractor is legitimate. It doesn’t tell you the price is fair. For that you need numbers to compare against, which is why our quoting ranges are public on the cost guide and explained with worked examples on what excavation costs in Jacksonville. For the phone call itself, take the questions worth asking.
