"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

"I worked with Jesse to help with a clogged bathtub drain after I tried plunging it myself. I explained over the phone that I was dealing with backflow problems and each time I used the bathroom sink the water would end up back in the tub. Unlike another plumber who said they would need to charge me to snake both the tub and the bathroom sink, Jesse explained it would likely just need to be the sink and there is an issue in the shared drainage pipe. Jesse communicated clearly when he'd arrive and on his availabilites, and helped resolve the issue quickly and cleaned up after himself. He also gave me additional advice on how to manage my drainage issues in the future, and another toilet problem I had. Good guy to work with, and got the job done. Would hire again."

"Mike was the first contractor to respond to my request. He came in the same day and inspected my bathroom plumbing for a suspected leak from the tub. He was very thorough and found a minor issue with the diverter which I asked him to replace. He knows his pipes and I am pleased to recommend his services to anyone looking for an honest plumber at a reasonable price."

"Went well. I thought that I might need a new trap or elbow since water was leaking. As it turned out, it was the sprayer that was leaking and not the elbow. The tech did not try to oversell me all new plumbing and I appreciate that."

"All Star Rooter was fantastic. gave me a straight assessment of the odds for my cleaning out my leaching field through removing roots and then blowing out with water which I appreciated. Odds were not good but we decided to go ahead rather than go straight into a replacement. Brian and team came over to take a look at our situation before starting and asked again if we wanted to proceed. He was professional and efficient and best of all it worked! I would highly recommend All Star Rooter’s services whether it worked for us or not."

"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."

"The team from Gallery of Kitchens & Baths gave our bathroom the upgrade it desperately needed. The Salvatori marble vanity and Pittori cabinetry make it feel brand new and incredibly stylish. The craftsmanship, communication, and professionalism throughout the process were outstanding. Kudos to them!"

FAQs for plumbing projects in Old Greenwich, CT

Schedule a plumbing inspection every one to two years to ensure your system is in good working order. Regular inspections can help you catch minor issues before they become costly problems, like major water damage repairs. You should also consider a plumbing inspection when buying or selling a home or if you notice signs of a plumbing issue. Staying proactive with maintenance can save you money and stress in the long run.

A plumbing inspection for a standard one-story to two-story home takes between two and three hours. For larger residences, historic homes, or rental complexes, a complete inspection requires a full-day commitment of eight hours. However, this does not account for any necessary repairs that your plumber might find, so it’s best to set aside additional time during the inspection in case an unexpected repair comes up.

When built with quality materials, your plumbing system endures for decades. CPVC, brass, iron, and steel provide reliable service for 50 to 70 years, while copper extends durability up to 100 years, and PEX maintains performance for 80 to 100 years. Maintaining this system with regular inspections and prompt repairs guarantees long-term efficiency.

You should repipe your home when your plumbing exceeds its expected lifespan or uses hazardous materials like lead, polybutylene, or galvanized steel. Persistent leaks, corrosion, and compromised water quality signal that your existing piping no longer meets safety standards. Repiping eliminates potential health risks and prevents extensive water damage.
