How to verify a Connecticut bathroom remodeler is licensed and insured

This guide covers general information, not legal advice. If a dispute with a contractor becomes serious, consult an attorney or Connecticut’s Department of Consumer Protection.

Checking a contractor’s license and insurance takes about fifteen minutes and it is one of the most useful things you can do before signing a bathroom remodel contract. Here is exactly how to do it.

Step 1: get the exact business name and license number

Ask the contractor directly for their Home Improvement Contractor (HIC) registration number and the exact legal name their business is registered under, which is not always the same as the name on their truck or website. A legitimate contractor will give you this without hesitation.

Step 2: look it up yourself

Connecticut’s Department of Consumer Protection runs a public license lookup tool where you can search by business name or license number. Confirm three things: the registration is currently active, the name matches what the contractor gave you, and there are no unresolved disciplinary actions on file. Do not rely on a contractor showing you a printed certificate; look it up independently.

Step 3: confirm insurance in writing

Ask for a certificate of insurance, not a verbal assurance. A proper certificate shows general liability coverage and, if the contractor has employees, workers’ compensation coverage. This matters more than it might seem: without it, you could be personally liable if a worker is injured on your property, or on the hook for repair costs if the contractor damages your home and has no coverage to fall back on.

What to check, in order

Check	Why it matters
HIC registration number matches state lookup	Confirms they are legally allowed to do the work
No unresolved disciplinary actions	Flags past disputes or violations
Certificate of general liability insurance	Protects you if property is damaged during the job
Workers’ compensation (if they have a crew)	Protects you from liability if a worker is injured on-site
Written contract with the license number listed	Required under Connecticut home improvement law

Why this step gets skipped, and why it should not

Verification takes a small amount of time relative to the size of a remodeling project, but it is easy to skip when a contractor seems friendly and a quote sounds reasonable. The problem is that friendliness and a low price are exactly what an unlicensed or underinsured contractor relies on. A legitimate, established contractor will not be bothered by you checking; if anything, offering the license number unprompted is itself a small positive sign.

What happens if you skip it

If a contractor turns out to be unlicensed and something goes wrong, your options for recourse narrow considerably. Connecticut’s Home Improvement Guaranty Fund, which can help reimburse homeowners for losses caused by a registered contractor, generally does not apply to work done by someone who was never properly registered in the first place. The same goes for insurance: if an uninsured worker is injured in your bathroom, the cost of that injury can fall on your homeowner’s policy or on you directly, not on the contractor. None of this is likely with an established local business, but it is exactly the scenario the fifteen-minute check above is meant to rule out before you are financially committed.

Reading sentiment alongside credentials

Licensing and insurance confirm a contractor is legally allowed to do the work and covered if something goes wrong. They do not tell you whether the work will be good or whether the contractor communicates well. That is where reviewing real customer feedback helps fill the gap. Connecticut bathroom remodelers on this site are scored using a published, transparent process that weighs review sentiment, not just star counts, which is a useful complement to the credential check above. You can read exactly how that scoring works on the methodology page.
