"Would Recommend Shelton Plumbing to anyone looking for someone to work with that makes the process super easy. After having a different local coming to my house for an estimate I spent $200 for their dispatch fee and evaluation just for them to tell me I needed a new water heater but that it would be 2 weeks before they could install it for a pretty penny. I requested a quote from Shelton plumbing on Angis and he called me within 10 minutes and was at my house the next morning at 8:30am installing my new water heater at a much better price. I’m so thankful for his service and easy going attitude. They had everything done within an hour and cleaned up everything and hauled away the old water heater. Thank you guys so much!"
