There are hundreds of construction companies in Boston, and on paper many of them look the same. The difference shows up once the work starts: how they handle permits, how they price changes, and whether they pick up the phone when something goes wrong.

Whether you’re planning a full gut remodel, a new build, a roof deck, or exterior repairs on an older building, the questions below will help you compare Boston construction companies and choose one you can trust with your property.

1. Are you licensed and registered in Massachusetts?

This is the first question for a reason. In Massachusetts, the person overseeing structural work generally needs a Construction Supervisor License (CSL). Contractors doing home improvement work on existing one- to four-unit owner-occupied homes also need to be registered as a Home Improvement Contractor (HIC). Ask for license and registration numbers and look them up yourself on the state’s website. A reputable construction company will share them without hesitation.

2. Are you insured, and can I see the certificate?

Ask for proof of general liability insurance and workers’ compensation coverage. If a worker is hurt on your property or something is damaged, you don’t want to find out afterward that the contractor wasn’t covered. Ask to be sent a certificate of insurance directly from their insurance agent.

3. Have you worked in my neighborhood and on my type of building?

Construction in Boston is not one-size-fits-all. A brick row house in the South End, a triple-decker in South Boston, and a condo building in Back Bay each come with their own challenges, from tight access and shared walls to historic district rules. Ask to see recent projects similar to yours, ideally nearby. A contractor who already knows the neighborhood’s buildings will spot problems sooner and plan around them.

4. Who handles permits and inspections?

Boston’s permit process can be the difference between a project that starts on time and one that waits months. Depending on the scope, a project may need building permits, zoning relief, or historic commission review.

A good construction company will tell you upfront which approvals your project likely needs, who will file them, and how long they typically take. Be cautious of any contractor who suggests skipping permits to save time; it can cause problems with insurance, inspections, and selling the property later.

5. What is included in your estimate, and what isn't?

The lowest bid is not always the lowest final cost. Compare estimates line by line. Ask what’s included for demolition, materials, finishes, permits, cleanup, and dumpster fees, and what allowances are built in for items you haven’t picked yet. Also ask how change orders work. Changes happen on almost every project, so you want a clear, written process for pricing and approving them before the work is done.

6. Who will be my main point of contact?

Ask who will run the job day to day and how often you’ll get updates. Will there be a project manager on site? How quickly do they return calls and emails? Clear communication is one of the best predictors of a smooth project, and one of the most common complaints when it’s missing.

7. What is your schedule, and what could delay it?

Ask for an estimated timeline from start to finish, including permit time. A trustworthy contractor will be honest about what could push the schedule back, such as material lead times, inspections, weather, or hidden conditions behind walls in older Boston homes.

8. Do you offer a warranty, and can I talk to past clients?

Ask what warranty comes with the work and what it covers. Then ask for two or three recent references, and actually call them. Ask past clients whether the project stayed on budget, how problems were handled, and whether they would hire the company again.
