Which of the following is NOT a sign of a potential home repair scam?

The option highlighting contractor referrals from trusted friends is indeed not a sign of a potential home repair scam. This is because referrals from friends or acquaintances who have had positive experiences with a particular contractor can serve as a reliable source of information. Trustworthy recommendations are essential in the home repair industry, as they can help homeowners find reputable professionals who are known for their quality work and integrity.

On the other hand, the other options listed—upfront payment requests, installation offers following a storm, and unsolicited offers—are commonly associated with deceptive practices. Scammers often ask for payment in advance to avoid completion of the work or provide subpar services. Additionally, after severe weather events, fraudsters may use urgency to pressure homeowners into making hasty decisions regarding repairs. Unsolicited offers can signal that the contractor is neither vetted nor trustworthy, as they might be seeking to exploit unsuspecting homeowners. Recognizing the contrast between the reliability of personal referrals and these warning signs can help individuals avoid falling victim to scams.
