The 6-Step Verification Sequence
5 minutes total. Run on every MA contractor BEFORE scheduling the in-home consultation.
Total time: PT5M
- Step 01
Search MA Home Improvement Contractor (HIC) registry
Visit mass.gov/orgs/office-of-consumer-affairs-and-business-regulation → 'Look Up Home Improvement Contractor.' Enter company name. Required for any project over $1,000. Database returns: HIC number, registration status, expiration date, principal name, business address. No HIC = walk away (no Home Improvement Guaranty Fund coverage). - Step 02
Search MA Construction Supervisor License (CSL) database
Visit elicensing21.mass.gov/CitizenAccess/ → search by license number or holder name. Required for any structural work (wall removal, additions, framing, beam install). Database returns: CSL number, classification (1A unlimited, 1R restricted residential, etc.), expiration date, holder name. The CSL holder is legally responsible for the structural work; verify the HOLDER name matches the company's principal. - Step 03
Search Master Plumber + Master Electrician databases (when relevant)
248 CMR Master Plumber: mass.gov → Board of Plumbers and Gas Fitters license search. 527 CMR Master Electrician: mass.gov → Board of State Examiners of Electricians. Required for any plumbing or electrical work. Verify the contractor either holds the license themselves or has a documented partnership with a license-holder for the work. - Step 04
Search MA Office of Consumer Affairs complaint history
Same Office of Consumer Affairs site has a 'Search Complaints' function. Enter company name. Returns any consumer complaints filed against the contractor in past 7 years. Pattern of unresolved complaints = walk away. Single resolved complaint = ask the contractor about it (most reputable contractors have at least one in their history). - Step 05
Verify Certificate of Insurance (COI) by direct call to carrier
Request COI from contractor. The certificate lists: insurance carrier name + policy number + coverage limits + expiration date. CALL the carrier directly using the carrier's published phone number (not a number on the COI itself). Confirm policy is active and limits are current. Forged COIs are common in unlicensed contractor scams. - Step 06
Cross-check BBB + Google reviews + references
BBB rating (bbb.org search by company + state): A+ standard for reputable; B and below = caution. Google reviews: 50+ over 2+ years, detailed, with owner responses to negatives. References: 3 recent (past 12 months) from similar projects; call them. The combination of state database + insurance + BBB + reviews + references catches 99% of unlicensed/scam operations.
Frequently Asked Questions
What if a contractor's HIC has expired?
Expired HIC means the contractor isn't currently registered. They may be in renewal limbo (typical 30-day grace period) or simply lapsed. Either way: don't sign with an expired HIC. Ask them to renew first; check back in 1-2 weeks. Active HIC is non-negotiable.
Can a sole proprietor contractor have HIC and CSL?
Yes — most MA contractors are sole proprietors or small LLCs. HIC registers the BUSINESS; CSL is held by an INDIVIDUAL (the construction supervisor). For most small MA contractors, the same person holds both — HIC business in their name + CSL in their personal name.
How do I search by license number vs company name?
Both supported in all MA databases. License number search is more precise; company name search returns multiple matches if the name is common. When in doubt, search by both — the records should match.
What if the company name on the contract is different from the HIC name?
Red flag. Possible explanations: (1) DBA (Doing Business As) — legitimate; verify the DBA registration with the Secretary of State. (2) Subcontracting arrangement — verify which entity is the contractor of record. (3) Unauthorized name use — likely a scam. The contract HIC and signatory entity should match.
Is the BBB rating reliable?
Mostly — BBB has weakened in some markets but for MA contractors, A+ is still a reasonable proxy for reputable. Look at COMPLAINT VOLUME + RESOLUTION RATE more than the letter grade. A contractor with 50 complaints (all resolved) is different from one with 3 complaints (all unresolved).
How do I file a complaint against a MA contractor?
MA Office of Consumer Affairs accepts online complaints at mass.gov/orgs/office-of-consumer-affairs-and-business-regulation. The office mediates between consumer and contractor. For unfinished or defective work, also file claim against the Home Improvement Guaranty Fund (up to $10,000 recovery).
Does this verification process apply to all trades?
Yes for the core trades requiring MA licenses: construction (CSL/HIC), plumbing (Master Plumber), electrical (Master Electrician), HVAC (handled under various licenses depending on scope), roofing (HIC for residential).
Can I verify a contractor's Mass Save HPC status?
Yes — separate from the state databases. Search at masssave.com/find-a-contractor by ZIP code; authorized HPC contractors are listed with HPC ID. This is REQUIRED for any heat pump install if you want the Mass Save rebate.
