Massachusetts has a home improvement contractor registration and a separate construction supervisor license, and the state's official website lets you look a contractor up. Do that before you sign anything, then compare the name you find with the name on the contract. We do not explain what the law requires here. The state's own site and an attorney can tell you what applies to your project.
Two credentials, two different jobs
When people say a contractor is "licensed," they may mean one of several things. Two credentials come up most often in Massachusetts home work.
Home improvement contractor registration
This is a registration that the state keeps for contractors who do residential remodeling and repair work. It is tied to a business or a person and is meant to help homeowners identify who they are dealing with and to give them a place to turn for complaints.
Construction supervisor license
This is an individual license related to supervising construction work. It is a different credential from the registration above. A company may show one, the other, or both, depending on the kind of work.
Whether either one applies to your chimney project, and how, is a question for the state, not for this page. Look at the current information on mass.gov, ask your local building department, or speak with an attorney if the job is large. Rules and programs change, so do not rely on a blog post, including this one, for the current requirement.
How to look a contractor up
The steps are simple, and they take only a few minutes.
- Ask the contractor for their full business name and the registration or license number they use.
- Go to the state's official website, mass.gov, and find the lookup for contractor registration or license. Type the address yourself rather than clicking a link someone sent you.
- Search by name or number.
- Read the result. Note the name, the status, and any details shown.
- Compare it with the name on the proposal and the contract.
A screenshot, a logo, or a number printed on a truck is not proof. Anyone can copy those. A lookup you run yourself, on the official site, is the check that counts.
If you cannot find the contractor, or the name does not match, ask why. There may be an innocent reason, like a trade name versus a legal name. Or there may not be. You are allowed to wait for an answer before you sign.
Does the name on the contract match?
The name on the contract should match the name you looked up. This sounds obvious. It is easy to miss.
- A friendly salesperson may work for a company that has a different legal name.
- A trade name on a flyer may not be the entity that signs the contract.
- A subcontractor may do the actual work under someone else's registration.
Ask directly who will be doing the work, who is responsible for it, and who is signing. If a subcontractor will be on your roof, you can ask how that is handled and who answers to you if something goes wrong.
Also confirm the address, phone number, and email on the paperwork are real and reachable. A contractor you cannot reach after the job is a problem even if the paperwork looks clean.
What a clear chimney contract should say
Registration is one piece. The contract is another. A homeowner should be able to read it and understand what will be done, for how much, and by when. Look for these:
- The full scope, described component by component, such as "rebuild top eight courses" rather than "fix chimney."
- Materials, by type.
- The total price and how it is paid.
- Any deposit, and when the rest is due.
- A start window and an expected finish, as estimates, not guarantees.
- How changes to the scope are handled, in writing, before extra work.
- Cleanup and debris removal.
- Cancellation terms.
Ask your own attorney or the state's consumer resources what rules apply to deposits and cancellation periods. Those rules are not something a chimney company should be explaining to you from memory, and we will not state them here. If any contract term feels unclear, ask for it to be changed before you sign.
Questions for the first phone call
You can learn a lot before anyone visits your house. Try these on any chimney company.
- What is your full business name, and what registration or license numbers do you use?
- Will your own employees do the work, or will a subcontractor?
- Do you send a written estimate with photos before work starts?
- What happens if you find more damage once you open the chimney?
- How do you handle debris, roof protection, and cleanup?
- Who do I call if there is a problem after the job?
Notice how the answers come. A clear, calm answer with details is a good sign. Vague replies, changes of subject, or irritation at the question are worth noting. You are not being difficult. Spending a few hundred or a few thousand dollars on masonry and roof work deserves a careful look at who you are hiring, especially on an older Boston home where the chimney sits above the roof and mistakes are costly to undo.
Paperwork to keep after the job
Keep a simple file for every chimney job, even a small one.
- The signed contract and any change orders.
- Proof of every payment, with dates.
- Photos from before, during, and after.
- The contractor's registration or license information as you found it.
- Warranty paperwork on parts, such as a cap or liner.
- Invoices and any written inspection reports.
These records help if you ever need to resolve a dispute, file an insurance claim, or sell the house. A buyer's inspector or a lender may ask whether work was done properly. Our guide to chimney inspection when selling a house shows why those records matter at sale time.
Warning signs worth pausing for
A missing license is only one reason to hesitate. These are others.
- A demand for a large cash payment up front.
- Pressure to decide today because the price "expires."
- A quote with no itemized scope.
- An unwillingness to show photos of the problem.
- A claim that your chimney is dangerous with no evidence.
- Door-to-door offers right after a storm.
A fair contractor can handle slow, careful questions. For more on this, see our guide to chimney scam warning signs and our list of questions to ask a chimney contractor.

We make no claim on this page about registration or licensing. Look up any company on the state's official website and judge for yourself.

Questions homeowners ask
Where do I look up a Massachusetts contractor?
Use the state's official website, mass.gov, and find the contractor registration or license lookup there. Type the web address yourself and search by the contractor's name or number.
Is a registration number on a business card enough?
No. A printed number can be copied or out of date. Run the lookup on the official site and confirm the name matches your contract.
What is the difference between registration and a license?
They are two separate credentials, one for the home improvement contractor and one for construction supervision. Check mass.gov for what each means and which applies to your project.
Should I pay a deposit before work starts?
Deposit rules are a legal matter, so check mass.gov or ask an attorney what applies. Whatever the amount, it should be written into the contract, with the schedule for the remaining payments.
What if I cannot find the contractor in the lookup?
Ask them to explain, and try searching under a different spelling or business name. If you still cannot confirm them, pause before signing and speak with the state or an attorney.
