How to Hire a Home Improvement Contractor in Massachusetts

To hire a home improvement contractor in Massachusetts, confirm the contractor holds a Home Improvement Contractor (HIC) registration and, for permitted or structural work, a Construction Supervisor License (CSL), then get a written contract and keep the deposit to no more than one third of the price. Ask for proof of liability and workers' compensation insurance, and make sure the contractor pulls the permit in their own name.

That is the short version. Below is what each of those means and why it matters, from people who sign these contracts every week.

Check the HIC Registration

Massachusetts requires contractors who do residential contracting work on existing owner-occupied homes with one to four units to register with the state as a Home Improvement Contractor. That covers most of what homeowners hire people for: roofing, siding, windows, decks, remodeling, and additions.

The registration matters for a practical reason. Massachusetts runs a Guaranty Fund that can reimburse homeowners for certain losses caused by registered contractors, such as abandoned or incomplete work, after other remedies have been tried. The Guaranty Fund only covers work done by HIC-registered contractors. If you hire someone who is not registered, you are not eligible for it.

The state also runs an arbitration program for disputes with registered contractors, which is generally faster and cheaper than going to court.

Check the Construction Supervisor License

The HIC registration is about consumer protection. The Construction Supervisor License is about competence. In Massachusetts, a CSL is required to supervise work that needs a building permit and involves the structure of a building, such as framing, roofing, decks, additions and structural repairs.

The two are separate. A contractor can be HIC-registered without holding a CSL, and the reverse is true as well. For most real projects, you want both: the HIC for your protection and the CSL so someone qualified is responsible for the work meeting the building code.

How to Look Them Up

Both the HIC registration and the Construction Supervisor License can be checked online through the state's license lookup on Mass.gov. You can search by name or by registration or license number.

When you look a contractor up, check:

• That the registration or license is active, not expired.
• That the name matches the person or company on your contract.
• The type of license, if the work involves specialized trades.

Do not take a business card or a number printed on a truck as proof. It takes two minutes to verify.

Get a Written Contract

In Massachusetts, home improvement contracts over $1,000 must be in writing. A proper contract should include, at a minimum:

• The contractor's name, address and HIC registration number.
• A clear description of the work and the materials, including brands and models where it matters.
• The total price and the payment schedule.
• The start date and the substantial completion date.
• Who pulls the permits.

Vague contracts are where disputes start. "Replace roof" is not a scope. "Remove existing shingles to the deck, replace damaged sheathing at a stated price per sheet, install underlayment, ice and water barrier, drip edge and architectural shingles from a named manufacturer" is a scope.

Keep the Deposit Reasonable

Massachusetts generally limits the deposit a home improvement contractor can collect up front to one third of the total contract price, with an exception for special-order materials. Items like custom windows, which are built to order and cannot be returned, may justify a larger payment toward their actual cost.

After the deposit, payments should follow progress. A contractor asking for half or more of the job up front on standard materials is a warning sign.

Ask for Proof of Insurance

Registration and licensing do not replace insurance. Ask for certificates showing:

• General liability insurance, which covers damage to your property and injuries to third parties.
• Workers' compensation insurance, which covers the crew if someone gets hurt on your job. Without it, an injured worker may look to the homeowner.

The certificate should be current and name the same company that is on your contract. You can call the insurance agent listed on the certificate to confirm it is active.

Make Sure the Contractor Pulls the Permit

If the job needs a building permit, the contractor should pull it in their own name. That makes them responsible for meeting code and passing inspections.

There is another reason this matters in Massachusetts: homeowners who pull their own permits while using a contractor can lose access to the Guaranty Fund and the state arbitration program. If a contractor asks you to pull the permit yourself, ask why. Usually it means they are not licensed for the work. For an example of how permits work on a common project, see our post on deck permits on Cape Cod.

Look at References and Local Work

Ask for references from recent jobs similar to yours, and ask for photos of finished work in your area. On Cape Cod, local experience matters: salt air, wind exposure, conservation commissions and historic district review all affect how a job is planned and built. A contractor who works the Cape regularly will know how your town's building department operates.

When you call references, ask whether the job finished on schedule, whether the price changed and why, and whether the contractor came back to fix anything that needed it.

Red Flags to Walk Away From

• Cash only, or a discount for paying in cash with no paperwork.
• No written contract, or a one-line estimate they want you to sign as the contract.
• A large deposit well beyond one third for standard materials.
• Pressure to sign today, or a price that is only good if you decide on the spot.
• Door-to-door offers after a storm from crews you have never heard of. We cover storm chasers in our guide to storm prep for Cape Cod homes.
• Reluctance to share registration, license or insurance information.
