"Aldo responded quickly. He stopped by and gave me an estimate to install a new faucet in a bathroom, and fix a minor leak with a toilet. He offered to do both jobs immediately. Nice clean job."

"Mike was great. He gave a very competitive qoute and took the time to explain the work that he would be doing. He was very professional and helpful from beginning to end. He installed a new Combi Boiler for us in 2 days now we have hot water and heat working perfectly once again. I would recommend Mike for any job. "

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"Rob was the plumber who came out and he was fantastic! He was professional, very nice, loves dogs and did a great job. He explained things to me so that I knew what he was doing. He also helped me save money by going back to a manufacturer to get a part that was not working...and the part is being shipped now for free! I would highly recommend Russo for any plumbing needs. I've used them before and was always very happy with the results."

"The job could not have gone better! Petey and his assistant went above and beyond the scope of work, carting the old sink away instead of leaving it for this old lady to deal with; also moving the heavy cooktop to a safer location than I was going to have it. He arrived ready to work; got right to it (both times) and was very professional. He was also thoughtful and considerate. I thought the job to reconnect and instal everything was going to take much longer but he had it done in less than 40 minutes- start to finish- which included checking to make sure the cooktop worked, the gas was connected properly with no leaks, the water ran well with no leaks, and that I was pleased with the job. I was missing a sink plug and he provided one right on the spot. HE COMES PREPARED!!! I will most certainly use him again for any plumbing needs for the property. The cost I quote below is what I paid for both visits combined ( the disconnect and the reconnect/instal)."

FAQs for gas piping projects in Old Greenwich, CT

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
