Frequently Asked Questions
What is the difference between a licensed and unlicensed contractor?
A licensed contractor has met state-specific requirements including education, experience, exams, and background checks. They carry required insurance and bonds. An unlicensed contractor has met none of these requirements. Hiring an unlicensed contractor may void your homeowner's insurance, expose you to liability if a worker is injured, and leave you with no legal recourse for defective work.
Does a license guarantee quality work?
No. A license means the contractor met minimum standards at the time of licensing. Always check reviews, ask for references, and see past project photos. However, a licensed contractor provides legal protections that an unlicensed contractor does not.
What is a contractor bond and why does it matter?
A contractor bond (surety bond) is a three-party agreement between the contractor, a bonding company, and you. If the contractor fails to complete a job or causes damage, you can make a claim against the bond. Bonds typically have limits ($5K-$100K) — they are a baseline protection, not comprehensive coverage.
What is contractor liability insurance?
General liability insurance covers property damage and bodily injury caused by the contractor. Always ask for a Certificate of Insurance showing at least $500,000-$1,000,000 in general liability coverage.
What is workers compensation and why do I care?
Workers' compensation covers contractors and their employees if injured on your property. Without it, an injured worker could potentially sue you as the property owner. Always verify workers' comp coverage before work begins.
Can I hire an unlicensed contractor to save money?
The risks are significant: work may not pass inspection, homeowner's insurance may deny claims, you could be liable for injuries, and you have limited legal recourse. Where contractor licensing is required by law, hiring unlicensed is also illegal.

Hiring Tips
Always Verify a License Before Hiring
Before signing any contract, verify the contractor's license on your state licensing board website. License lookup tools are free and take less than a minute. Never accept a license number without verifying it yourself.
Get At Least Three Written Bids
Always get at least three written bids for any project over $1,000. Bids should be itemized and specify materials, labor, timeline, and payment schedule. Beware of bids significantly lower than others.
Check Insurance Separately from Licensing
A contractor can be licensed but uninsured. Ask for a Certificate of Insurance (COI) naming you as additional insured. Verify it is current by calling the insurer. Both general liability and workers' compensation are important.
Never Pay More Than 10-30% Upfront
Be cautious of contractors demanding large upfront payments. A typical schedule: 10-30% down, incremental payments as work progresses, and 5-10% retained until completion and inspection.
