South Florida has thousands of contractors — and the difference between a great one and a costly mistake is almost entirely checkable before you sign. Here are the seven checks we'd run on any contractor, including ourselves.
1 Verify the license — don't just ask for it
Every legitimate general contractor in Florida has a license you can verify in two minutes at myfloridalicense.com (Florida DBPR). A Certified General Contractor license starts with CGC. Confirm it's active, current, and registered to the exact company on your contract. Ours is CGC1525512 — we'd rather you check than take our word for it.
2 Demand insurance certificates from the insurer
General liability and workers' compensation, minimum. Ask the contractor's insurance agent to email the certificate directly to you — a PDF forwarded by the contractor can be outdated or edited. If a worker gets hurt on your property and the contractor has no workers' comp, that risk can land on you.
3 Pull the permit history — it's public and it doesn't lie
Permits show what a contractor actually built: how many projects, what size, which cities, and whether violations were filed. Aggregators like BuildZoom compile this record. Reviews can be curated; permit history can't. (Ours: 31 permits filed since 2021, over $13M in construction value, zero violations.)
4 Get a written, itemized contract
Scope, materials, allowances, payment schedule tied to milestones, change-order process, and timeline. "We'll figure it out as we go" is how $60,000 projects become $90,000 projects. An itemized contract also makes bids comparable — you can see exactly what one contractor includes that another quietly excluded.
5 Watch the deposit structure
Progress payments tied to completed milestones are normal. Large upfront cash deposits are not. Florida's construction landscape has a long history of deposit-and-disappear schemes — a professional with real supplier relationships doesn't need half your budget before day one.
6 Know who actually runs your project
Ask: who is my point of contact? How often will I get updates? Who is on site daily? In a family-run operation you typically talk to the owner; in a volume shop you may get a rotating project manager juggling a dozen jobs. Neither is automatically wrong — but you should know which one you're buying.
7 Be suspicious of the lowest bid
When one bid comes in far below the rest, the missing money is hiding somewhere: excluded scope, thinner materials, unlicensed subs, or change orders waiting to happen. The right comparison isn't price alone — it's price against a fully itemized scope.

Frequently asked questions
How do I verify a contractor's license in Florida?
Search the license number at myfloridalicense.com. Confirm it's active and matches the company on your contract. CGC = Certified General Contractor.
What insurance should they carry?
General liability plus workers' compensation — with certificates sent to you directly by the insurer.
How do I check their real track record?
Public permit history (aggregated on BuildZoom and county portals): project count, construction value, and violations on record.
What's the biggest red flag?
Any suggestion to skip permits or to have you pull an owner-builder permit for their work. Both shift risk from them to you.
