Whether it’s an unlicensed roofer demanding payment upfront or a handyman who disappears mid-job, these scenarios share one thing in common: they exploit trust.</p> <p>The good news is there are many proven ways to protect yourself before making a hiring decision. Here are five good places to start:</p> <p><strong>1. Verify license and insurance.</strong> One of the simplest ways to prevent home improvement fraud is to confirm that the company holds an active license with the <a href="https://www.cslb.ca.gov/" target="_self">Contractors State License Board (CSLB)</a>. Always check the license number and ask for proof of both liability and workers’ compensation insurance.</p> <p>Diamond Certified companies are already vetted on these points. Every Diamond Certified contractor has been independently verified for license, insurance coverage, business practices and customer satisfaction before earning the award.</p> <p><strong>2. Beware of “too good to be true” prices. </strong>Fraudulent contractors often attract customers with unusually low bids, only to raise their prices after work begins or vanish with the deposits. A fair estimate should include detailed costs, a project timeline and warranty information.</p> <p>Diamond Certified contractors follow strict business standards that prohibit deceptive pricing and unfulfilled promises. Homeowners who choose Diamond Certified companies are also protected by the <a href="https://www.diamondcertified.org/performance-guarantee/" target="_self">Diamond Certified Performance Guarantee</a>, which can refund up to $1,000 if mediation fails to resolve an issue.</p> <p><strong>3. Get everything in writing. </strong>Never rely on a verbal agreement. A legitimate contractor will provide a written contract that includes a clear scope of work, the payment schedule, and start and completion dates. If a contractor hesitates to provide documentation or pressures you to sign on the spot, consider it a red flag.&nbsp;</p> <p><strong>4. Check for reputation and longevity. </strong>A quality company should have a traceable history, satisfied customers and consistent business operations. <a href="https://www.diamondcertified.org/whats-in-each-diamond-certified-company-report/" target="_self">Diamond Certified’s deeply researched company reports</a> and verified customer surveys make it easy to see all of these elements.</p> <p><strong>5.
