Caution & regulatory history

Board discipline from Florida extracts linked to this contractor. Separate from insurance, permits, or reviews — factual records only.

No discipline records identified in current extracts

No discipline records identified in current extracts

Our Florida board discipline files do not currently attach an action to this profile. That is not a certificate of clean history: records may exist outside these extracts, under another name, or after our last load. Re-check the official DBPR board before hiring.

What this means: absence in our extract ≠ cleared. Worth confirming on the official source the day you hire.

Notes comparing license and Sunbiz

These differences are common in public records and are not automatic red flags. We show them so you can double-check details before you hire.

  • License active, entity status is not

    Worth confirming

    Florida DBPR shows Active; entity filing shows Inactive. Re-check both before you sign — confirm which party is contracting.

Insurance & workers' compensation

Coverage status is not shown in our current extracts. Homeowners should request and verify documents with the carrier — we do not mark anyone as “insured,” “fully covered,” or “approved.”

Evidence status on this report

Not shown in current extracts — confirm with carrier before hiring THERMAL LINE INC.

What to request

  • · Certificate of Insurance (COI) for general liability
  • · Workers' compensation evidence or exemption status where applicable
  • · Named insured matching the contracting entity (on file: THERMAL LINE, INC)
  • · Policy effective and expiration dates

How to verify

  • · Call the carrier contact listed on the COI to confirm active status
  • · Confirm contractor / entity name matches your contract
  • · Keep copies with your project records
  • · Re-check dates before work starts and after any change order

Why workers' comp matters (Florida)

If a contractor is required to carry workers' compensation and does not, you may face liability and project risk if a worker is injured on your job. Requirements depend on structure, employees, and exemptions — the Division of Workers' Compensation is the authority. Homeowner should confirm with carrier and official portals.

Public permit / work records

Public permit/work records linked to this contractor license by an exact license-number match. A permit record is not an endorsement, and more or fewer permits on file is not a quality signal. Where we cover

Not linked

No confirmed public permit records are currently linked to this license

This is not a finding that the contractor has performed no work, and it is not a finding about license standing. Coverage is currently limited to Miami-Dade County, FL building permits with an exact contractor-license match on the permit record — a contractor may have permit history outside this coverage, or the source may not have published a matching record.
