What red flags are common when hiring a solar installer in Marietta's growing market?
In Marietta, verify your solar installation contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work. Be cautious of solar installation contractors in Marietta who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. Marietta's rapid growth attracts out-of-state contractors who follow the boom. Verify any unfamiliar company's local licensing, physical address, and track record. Fly-by-night operations leave when the market cools.
