"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"

"This was the second time we used H L Bowman for our plumbing needs and we have been impressed both times. Their plumbers are prompt, courteous, and friendly, in addition to being great at their craft. For this visit, I had a leak under a kitchen sink and did not realize that I needed to have the entire faucet replaced. The plumber recommended the closest plumbing supply store and waited while I selected the one I wanted. He efficiently did the replacement. Very happy with H L Bowman and would highly recommend them."

"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."

"I've used All Star Rooter on three occasions and have been very pleased with the work provided. Always professional, punctual and careful, they are specialists. An important indicator of their skill is their position in the industry - three different plumbing companies have recommended All Star Rooter. They will calmly approach a stressful situation and do their best to reach a successful outcome. On this occasion they were able to clear an on-going clog efficiently."

FAQs for plumbing projects in Cos Cob, 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.
