Flaherty Plumbing & Heating says it has been in business for 77 years, and its website lists a service area running from Norwalk, Greenwich and Stamford to Westport, Southport and Fairfield. A 2022 customer said that after two visits from the oil company that installed their hot water heater failed to fix a loss of hot water, Flaherty set an appointment for the very next day. In that 2022 account, the technician diagnosed a defective thermostat in five minutes, was back with the part in under an hour, and had the issue resolved before the originally scheduled appointment time. A 2022 customer said Lou helped with frozen pipes and repaired them promptly. A 2024 customer said the company came out the same day and fixed a rusted out shower drain for a reasonable price. A 2024 customer wrote that they had used Flaherty for years at a house and a rental property, including for emergencies with broken showers and drains. A 2022 customer dealing with a leak and a burst pipe said the woman in the office was kind, patient and responsive. A 2024 customer said the company installed a back flow pressure device for a sprinkler system, turned the water on without telling them, and the system froze two months later; that 2024 customer said the company was unwilling to work with them to fix the mistake. A 2021 customer called the service very, very expensive and said the company may be busy for people not well known to it.

Had them install a back flow pressure device for my sprinkler system in the fall. The system was off and winterized and the water had been off. They turned the water on and never told me or turned off. It froze 2 months later after not being touched. When I let them know they were unwilling to work with me to fix the mistake. Better customer service would go a long way here.
I have used Flaherty for years both at my house and at my rental property. They are always clean, professional, and reasonably priced. They have handled several emergencies for me, including broken showers and drains as well as general repairs of leaky dishwashers or to replace my garbage disposal. This guys are communicative and clear. Great team.
Excellent service thank you as always! Have been using them for years.
The amount of times I have called Flaherty Plumbing for emergency services that range from burst water mains to washing machine leaks, you would think they'd be sick of me by now. But, because they are so excellent at what they do, they are unlikely to get rid of me any time soon. I really can't say enough about Jeff and how thoughtful, efficient and responsive he and his team are. They are in the middle of saving me from another plumbing crisis right now, so no better time to show them some review love. Thank you Flaherty Plumbing!
Thorough, prompt, and reasonable service from Lou and the team at Flaherty.
