In July 2025 a Google reviewer wrote that they had been using McGuire Plumbing & Heating for over 20 years, called it "the plumber you want for all your plumbing issues," and said call-back time is the very next day, with Jeff "super accommodating." An October 2024 reviewer signed Nancy M. of Lisbon, CT wrote of doing business with both Jeff Cassidy and Paul McGuire for almost two decades, through "our many plumbing and heating problems." The Voluntown company, at 43 Lillibridge Ave, says on its site that it is a family-owned small business with 40 years in business, serving Killingly, Norwich, Griswold and all of New London County. It holds 4.5 stars from 24 Google ratings. A January 2026 reviewer called it the only plumbing company they trust, writing that they return calls, will talk the customer through something, and leave with the job completed. A February 2026 customer got a quick return phone call and on-time service at a price they called very reasonable. In March 2025 a caller left five messages over a week with the answering service, got no return call, and wrote of a bad attitude from the answering service.
Quick return phone call. On time, professional service. Very reasonable and we were extremely happy with the entire process. Thank you
McGuire plumbing is the only plumbing company I trust. They return calls, help me even if it's just talking me through something, and always leave with the job COMPLETED. Super great company, great customer service, and overall, extremely professional.
The plumber you want for all your plumbing issues. I've been using McGuires for over 20 years and have been more than pleased with their service and work. Unlike a couple of other plumbing businesses that do not return calls for service and then cry about how 'they're a small business trying to help people but they're "too tired" to call customers back' is not the case with McGuires. Call back time is the very next day and Jeff is super accommodating and customer friendly. You can't go wrong with McGuires!
Never had a better Plumber he knows what he is doing !
