Red flag
Cash-price bargaining and offer of a lower price for cash payment on a water heater quote
“the water heater and labor will be 2500 (mind you a 50 gallon electric water heater is about 600 dollars, so bascially Charing 1900 for labor)”
One reviewer was quoted $2,500 for a 50-gallon electric water heater install ($1,900 labor) and was offered a cash discount when they pushed back

The evidence — in reviewers' own words
Critical
“I've gotten no less that 4 spam emails to leave a review for them so here goes. I've not had a single repair done with DnA that I didn't have to have them back again to fix. The saga of our water heater is a long one so buckle in. We had a water heater installed in our barn before the barn was finished.

If you pay cash …”

“DNA professionals repaired our septic system quickly and efficiently. This isn't the first time we have used them. Their honesty and quality work the last time they were out made us loyal customers and they will be the only ones we call with plumbing issues.”
“D-N-A plumbing was a great experience, they showed up on time. Miguel was very polite, and understood the issue, explained it to me in detail. They made the repairs quickly and the cost was reasonable. It was nice to find a company these days that that actually have great customer service, with a smile. Thank you for your assistance to resolve our issue. PS: They each left with a homemade cookie that my wife gave …”
