Which of the following is a red flag to avoid in home repair scams?

Requesting large upfront payments is indeed a significant red flag when it comes to avoiding home repair scams. Scammers often ask for a large portion of the payment before any work is done, which can leave the homeowner vulnerable if the contractor fails to perform the work or disappears after receiving the money. Legitimate contractors typically ask for a reasonable deposit or payment schedule tied to the completion of various stages of the project rather than demanding a large sum upfront.

In contrast, estimates provided in writing, positive online reviews, and a high level of customer service are generally indicators of reputable business practices. Written estimates provide clarity on costs, helping homeowners make informed decisions. Positive online reviews are a sign that a contractor has a good track record, and high levels of customer service may reflect a contractor's commitment to their work and client satisfaction. Hence, understanding the significance of payment requests can greatly aid in differentiating trustworthy contractors from potential scammers.
