Before you sign

Hiring a flooring contractor

Installation is the largest single cause of flooring failure. Whether that ever becomes someone else’s problem rather than yours is decided before the work starts — by six things you can check in an afternoon.

Why there is no table of state rules on this page

Licensing thresholds, bond amounts and even agency names are revised most years, and a great deal of the regulation is not at state level at all — it sits with your city or county. A table would be accurate the day it was written and quietly wrong eighteen months later, and acting on a stale row is how someone hires an unlicensed contractor believing they did not need one.

While researching this page, published sources disagreed with each other about which states license contractors at state level. So this page covers the checks, which do not change, and points you at the agencies for the rules, which do.

Find your state

Where to look up the rules where you live

NASCLA’s Contractor State Licensing Information Directory covers licensing thresholds, the responsible agency, bonding requirements and reciprocity for all fifty states, the District of Columbia and the territories.

It is worth knowing why we send you there rather than reprinting it: NASCLA is the national association of the state licensing agencies themselves, and they maintain the directory. Any copy we kept here would be a worse version of it within a year.

Then check your city or county separately. A contractor can hold a valid state license and still be unregistered locally, and only one of those shows up on a state lookup.

For flooring specifically, our installer directory says what “licensed” means for the trade in every state, and lists installers checked against the state register where one exists — California first.

The checks

Six things to verify before you sign

None of these depend on which state you are in. Only the threshold at which they become legally required does.

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.

Why it is confusing

Why the rules vary so much

It is usually a dollar threshold, not a trade

Many states do not license flooring as its own trade. Instead a license is required for construction work above a set value, and flooring lands inside general contracting. That threshold varies by state and can be low enough that an ordinary room is over it.

Several states do not license at state level at all

In a number of states there is no statewide general contractor license and regulation sits entirely with cities and counties. That does not mean there is no requirement — it means the requirement is local. Texas has no state license, and several of its largest cities still require contractor registration.

Local rules stack on top of state ones

A contractor can hold a valid state license and still be unregistered in your city. Both matter, and only one of them appears on the state board lookup.

It changes yearly

Thresholds, bond amounts and even agency names are revised regularly. This is the reason this page sends you to the licensing agencies rather than reprinting their rules.

The one most people have never heard of

You can pay your contractor in full, and still have your house liened by a supplier you never hired. A mechanics lien can be filed by anyone who worked on the property or provided materials for it and was not paid — so if the money stops between your contractor and their supplier, the claim attaches to your home rather than to them. Homeowners in that position can end up paying twice, and the lien can block a sale or a refinance until it is resolved.

The protection is procedural and unglamorous: a signed, dated lien waiver with every payment from every party being paid, subcontractors and suppliers named in the contract, and joint checks where the amounts justify it.

Common questions

Hiring a contractor — frequently asked

It depends where you are, and the answer is more often about the size of the job than the trade. Most states license construction work above a dollar threshold rather than licensing flooring specifically, so a flooring installer frequently falls under general contracting once the job passes that value. Several states have no statewide general contractor license at all and leave regulation to cities and counties — which does not mean there is no requirement, only that it is local. Because the thresholds and the agencies change from year to year, check your state through NASCLA, the association of the state licensing agencies themselves.

Look the number up on the licensing agency's own website rather than accepting a photograph of a card or a number printed on a quote. Confirm three things beyond the number existing: that it is current, that the classification covers the work, and that it is held in the name of the business you are actually contracting with rather than an individual who happens to work there. Then check separately whether your city or county requires its own registration, because a valid state license tells you nothing about that.

They protect different people. A bond is a guarantee the contractor buys, from which a limited amount can be claimed if they fail to perform or fail to pay — it is not insurance for you, and the required amounts are often smaller than homeowners assume. General liability insurance covers damage the contractor does to your property. Workers' compensation covers injury to the people doing the work, and it is the one that can reach you personally, because in many states an uninsured worker hurt in your home can pursue the homeowner. A contractor can honestly say "licensed and bonded" while carrying none of the insurance that matters most to you.

In many states, yes, and it is the risk homeowners least expect. A mechanics lien can be filed by anyone who worked on the property or supplied materials for it and was not paid — including a subcontractor or supplier you never hired and never met. If you pay your contractor in full and the contractor fails to pay their supplier, the supplier's claim can attach to your home, and you may face paying twice. A lien can also block a sale or a refinance until it is cleared. The protection is procedural: get a signed, dated lien waiver with every payment from every party being paid, have subcontractors and suppliers named in the contract, and consider joint checks.

The contractor should, in their own name. Flooring on its own rarely needs a permit — it comes up when the work touches structure, subfloor framing, plumbing or electrical, or when it is part of a larger renovation. If a contractor asks you to pull the permit yourself, treat that as a question rather than a favor. A permit in your name makes you the contractor in the building department's eyes and moves responsibility for the work meeting code onto you, which is usually either because they cannot pull it or because they would rather the liability were yours.

A license is a floor, not a recommendation. It tells you someone met a state's minimum requirements and can generally be insured and bonded — it does not tell you they will power-stretch your carpet or test your slab. Most of the failures documented on this site are workmanship rather than credentials. What a license buys you is that when the work is wrong, somebody exists who is answerable for it, with insurance behind them. That is worth a great deal, and it is not the same as quality.

This is general information, not legal advice. Licensing, bonding, insurance and lien law are set by your state and often by your city, they change, and they turn on facts specific to your situation. The licensing agency for your state is the authority on its own rules, and a construction attorney in your state is the authority on the rest.
