Check 01
The license itself
Ask for: License number, and the name it is held in
What it is. Most states license contractors above a dollar threshold for the job — often a few hundred to a few thousand dollars — and flooring frequently falls under general contracting rather than a trade license of its own. Several states do not license at state level at all and leave it to the city or county.
Why it matters to you. An unlicensed contractor is often uninsurable and unbondable, which means that when something goes wrong there is nothing behind them. In some states it also limits their right to enforce the contract or to lien your property — which sounds like it protects you, and mostly means the money is already gone.
How to check. Look the number up on the state board's own site rather than accepting a photograph of a card. Check the name on the license matches the business you are contracting with, not an individual who happens to work there.
Red flag. A license number that belongs to someone else, an expired date, or a classification that does not cover flooring.
Check 02
The surety bond
Ask for: Bond number, amount and the issuing surety
What it is. A bond is not insurance for you — it is a guarantee purchased by the contractor, from which a limited amount can be claimed if they fail to perform or fail to pay. Required amounts vary widely by state and are often smaller than people expect.
Why it matters to you. It is the only pot of money that exists specifically because the contractor might not finish. It is usually not large enough to redo a whole floor, so treat it as partial recourse rather than a safety net.
How to check. Bonds are verifiable through the state board listing and through the surety named on it.
Red flag. "I am bonded" with no number, or a bond that expired between the quote and the start date.
Check 03
General liability insurance
Ask for: A certificate of insurance sent directly by their insurer
What it is. Covers damage the contractor causes to your property — the burst pipe, the scratched stair rail, the adhesive on the cabinets.
Why it matters to you. Without it, damage during the job is a dispute between you and a business that may have no assets. Your own homeowner policy is not designed to absorb a contractor's mistakes and your insurer may pursue them anyway.
How to check. Ask for the certificate to come from the insurance agency, not forwarded by the contractor, and check the dates cover your whole schedule.
Red flag. A certificate that expires mid-project, or a policy naming a different business entity.
Check 04
Workers' compensation
Ask for: Proof of cover for everyone who will be on site
What it is. Covers injury to the people doing the work. Flooring is kneeling, cutting, lifting and adhesives in enclosed rooms — the injury rate is not trivial.
Why it matters to you. This is the one that can reach you personally. In many states an uninsured worker injured in your home can pursue the homeowner, and a crew of "subcontractors" may or may not be covered depending on how they are actually engaged.
How to check. Ask specifically whether the people on site are employees or subs, and get proof for the subs too.
Red flag. "They are all independent contractors, so it is not needed." Sometimes true, often the answer that costs the most later.
Check 05
Permits, where they apply
Ask for: Who is pulling the permit, and is it in their name
What it is. Flooring alone rarely needs a permit. It appears when the work touches structure, subfloor framing, plumbing or electrical, or when it is part of a wider renovation.
Why it matters to you. A permit pulled in YOUR name makes you the contractor in the eyes of the building department, and shifts responsibility for the work meeting code onto you.
How to check. The contractor should pull permits in their own name. If they ask you to pull it, ask why.
Red flag. "You pull it, it is faster." It is faster because they cannot, or because they would rather the liability were yours.
Check 06
Lien waivers
Ask for: A signed waiver with every payment
What it is. A mechanics lien is a claim against your property filed by anyone who worked on it or supplied materials and was not paid — including a subcontractor or supplier you never met and never hired.
Why it matters to you. This is the risk homeowners least expect: you can pay the contractor in full, the contractor can fail to pay their supplier, and the supplier can lien your house. You may end up paying twice, and a lien can block a sale or a refinance until it is cleared.
How to check. Get a signed, dated lien waiver for each payment, from each party being paid. Ask for the subcontractors and suppliers to be named in the contract so you know who can make a claim. Joint checks, made out to the contractor and the supplier together, are a common protection.
Red flag. Reluctance to name suppliers, or a waiver offered only at the very end.
