What customers say
"★★★★★ Radiant Plumbing 🪠 serviced my home today and I couldn’t be more satisfied with the experience. They fixed a severely clogged double kitchen sink quickly and thoroughly. From start to finish, the service was professional, courteous, and honest. A special shoutout to Garrett, the plumbing professional who handled the job—he was polite, knowledgeable, and took the time to explain exactly what was going on and …"
— Wayne Flint · Feb 10, 2026 · Google Reviews"Gunner was amazing! He is quick and professional. Your guys are always great. I hope you are paying them more than most techs in the area. I have had such a good experience with the last 3 techs that have been sent out the past few years and that is the only reason I have you on speed dial. Your prices are competitive and I have had awful experiences in the past with other plumbing companies. Thank you!!"
— Lilia Jones · Feb 23, 2026 · Google Reviews"Gunner was awesome! Very professional and knowledgeable and fast. Couldn’t recommend his work enough. God forbid, but if we ever need any plumbing fixed, we will definitely be reaching out to have him come back out. Dee and Samantha were very helpful when I called to schedule my appointment. They set everything up to be fixed asap! Thank you Radiant!"
— Seven14 Media · Feb 5, 2026 · Google Reviews"On time to start with. That was a very pleasant surprise. Very cordial. Got right to work with little chit chat. It took him five minutes to locate the problem. He gave me quotes/estimates on potential issues and even tested my water and added my bag of salt to my softener. I am extremely pleased with Reliants service and would recommend to anyone."
