How to Choose a General Contractor in Connecticut

Hiring a general contractor is one of the biggest financial decisions most homeowners make, and Connecticut gives you real tools to vet one before you sign anything. This guide covers what to check, in what order, and, just as important, what each check does and doesn’t tell you. We’re a contractor writing this, so we’ll be straight about where the paperwork matters and where it doesn’t.

Step 1: Understand and Verify the State Registrations

Connecticut regulates residential contractors through registrations with the Department of Consumer Protection. The main ones you’ll encounter:

Every one of these can be verified in about a minute at elicense.ct.gov. Search the business name, confirm the registration is active, and note the number for your contract.

Now the honest part: these are registrations, not skill certifications. Being registered means the contractor filed with the state and is operating legally, and it preserves your legal protections. It does not, by itself, tell you they build well. Verification is the floor, not the finish line. A contractor’s track record, references, and the work you can see with your own eyes matter more than any number on a card. For the record, ours are HIC.0661478, NHC.0016349, and DMCR.003450 through our demolition division, and you should look them up rather than take our word for it.

Step 2: Insurance, and How to Actually Check It

Ask for a certificate of insurance (COI) showing general liability and workers’ compensation, and ask for it to be issued to you directly from the contractor’s insurance agent, not handed over as a PDF that could be outdated or edited. For substantial residential work, $1M in liability is a reasonable minimum; larger projects justify more (we carry $2M). Workers’ comp matters just as much: if an uninsured worker is hurt on your property, the claim can land on your homeowner’s policy, or on you.

Step 3: Ask Who Actually Swings the Hammers

There’s a wide spectrum between a contractor with employees on payroll and a broker who sells jobs and chains them through layers of subcontractors. Neither model is automatically bad, and every good GC uses licensed subs for trades like electrical and plumbing, since Connecticut requires it. But you should know what you’re buying. W-2 crews mean consistent training, direct supervision, and the same faces on your job from start to finish. Long sub chains mean the person who priced your job may never meet the people building it, and quality control depends on how many layers your money passes through. Ask directly: who is on site every day, and who do they work for?

Red Flags Worth Walking Away From

• •
  Big cash deposits up front. A deposit is normal; half the job in cash before a shovel moves is not. Payments should track progress.
• •
  No written contract. Connecticut’s Home Improvement Act requires one, with start and completion dates and notice of your cancellation rights. A contractor who shrugs that off is telling you how the rest of the job will go.
• •
  “We don’t need a permit for this.” For structural, electrical, plumbing, or roofing work, you almost certainly do. Unpermitted work surfaces at resale and in insurance claims.
• •
  Door-knockers and leftover-materials deals. Especially after storms. Legitimate contractors have more work than time.
• •
  A price far below every other bid. The gap gets recovered in change orders, substituted materials, or a job that never finishes.

Questions to Ask Before You Sign

1. Can you give me addresses of two or three completed projects like mine, and owners I can call?
2. Who supervises the site daily, and how do I reach them?
3. How do you handle change orders, in writing, before the work happens?
4. What does the payment schedule look like, and what triggers each payment?
5. Who pulls the permits? (The answer should be the contractor, not you.)
6. What happens if we find rot, ledge, or other surprises once work starts?

How to Read Reviews Like a Skeptic

Volume matters less than pattern and substance. Look for reviews that describe a specific project, mention names, and cover how problems were handled, because every real construction project has at least one. Check that reviews span years rather than arriving in one suspicious burst. Read how the contractor responds to criticism, since that’s a preview of how they’ll respond to you. Then triangulate: Google reviews, the DCP complaint history, and actual references. Any single source can be gamed; all three together are hard to fake.

We’ll put our own record on the table: 23 Google reviews, all five stars, a 5.0 rating, and referenceable projects across additions, full-scale remodels, new construction, and roofing. Apply everything in this article to us, too. That’s the point.
