Frequently Asked Questions (FAQs)
What happens if a claim is made against the bond?
If a valid claim is filed (e.g., due to code violations or unfulfilled contracts), the surety may pay up to the bond amount. The contractor is then responsible for repaying the surety.
Is the bond refundable if I cancel my license?
No. Once issued, the bond premium is generally non-refundable, even if you cancel your license mid-term.
Is the bond required for both individuals and companies?
Yes. Whether you are an individual sole proprietor or a business entity (LLC, partnership, or corporation), the Illinois Department of Public Health requires a $20,000 plumbing contractor bond as part of licensure.
Can I get bonded with bad credit?
Yes. Contractors with poor credit can still obtain a bond, but the premium rate will be higher (often 5–10% of the bond amount). Some sureties specialize in higher-risk applicants.
What happens if I fail to maintain the bond?
If your bond expires, is canceled, or is not renewed, your plumbing contractor license will be invalid, and you may face penalties, including suspension or revocation of licensure by IDPH.
