I have no reservations about highly recommending Preeferred Service, LLC. After paying a family friend who misdiagnosed my water heater problem as simply a burner cleaning project, I turned to Mr. Dupree, a licensed plumber for 20 years, who accurately diagnosed my difficulty as one requiring replacement of my burner assembly upon a free diagnosis/estimate call. Not too many independent contractors still offer a free service without requiring clients to select them for the project to recoup the price of an estimate call. Mr. Dupree gave me the option to secure my own part (which I did through Sears Parts Direct) and matched the lowest bid to perform the labor. I was so pleased with the outcome (and with no longer having a hot water heater issue) that I hired him to also replace the waste disposal in my kitchen. I purchased the part at Home Depot, and again, Mr. Dupree provided exceptional service at a fair price. He also documented everything by invoice with a 90-day guarantee of his labor. I will definitely call upon Preeferred Service, LLC for my future plumbing needs to get it right the first time. Mr. Dupree’s outstanding knowledge, skills, and abilities are matched by his professionalism, fairness, and customer service. Thanks, Thumbtack!
