"This was such a great experience! they were timely and did an unbelievable job. We were so pleased with the post installation work of repairing the walls and ceilings- you would never know there had been any repairs done! We would highly recommend them for anyone who has to have pipes replaced!"

Customers say: Super punctual

"We discover a leak in our main water line. With Richard Kashi's recommendation, we used a leak detection service to avoid digging in multiple locations. They found we had at least two leaks in the line. Richard and the leak detection pro recommended replacing the entire line since two leaks meant a serious problem. The line had been replaced about 12 years before, but they cut corners leading to our problem. The line replacement team was amazing. They ran a new, parallel line into the house above the previous leak. They also were able to tell me why we were having problems with the leak and through our wall from the old line. The difference in quality between the two was quite clear. They installed elbow joints instead of bending the copper, rerouted our pressure regulator in front of all other outlets (another mistake, wrapped the copper line with heavy tape before running it through the line so the wall wouldn't rub, and then pressure sealed the wall from both sides. I wish I had used them the first time."

"Fayetteville, GA. I had a water leak in front of my house. Rooter Pro Plumbing GA came early before their appointed time. They explained what the process and the cost to repair vs replacing. After an agreed service, they began the work and had it completed under two hours. Great customer service! I would recommend the company."

"I had them replace an old water faucet outside that was leaking. They were professional, gave good advice, and they did not pressure me into doing extra projects. I will definitely call them again for future plumbing issues."
