McGrath Plumbing & Heating is a Gloucester plumbing and heating contractor with a long local footprint. The BBB profile lists 51 years in business, four employees, and work in both plumbing and heating. Google shows four 5-star ratings. A July 2026 review describes two radiator installations plus a toilet and sink connection, with secure fittings, clear explanation, and thorough cleanup. A December 2023 customer said the company had handled cottage openings and closings, water-heater replacements, and leaks of different sizes over several decades. That mix points to a practical call for household plumbing, heating equipment, and leak work. Ask for the scope and estimate for your particular system before scheduling.
⭐⭐⭐⭐⭐ Excellent work from start to finish "Damian installed two new radiators, plus fitted and connected a toilet and sink for us. He was punctual, tidy, and took real care with every part of the job – all fittings are secure, everything works perfectly, and he even explained how to balance the radiators properly. He cleaned up thoroughly afterwards so there was no mess left behind. Friendly, professional, and fairly priced – we’d absolutely recommend him and would use his services again without hesitation."
We have used McGrath plumbing for several decades for everything from opening and closing a summer cottage, to replacing water heaters and fixing leaks both small and large. They are super reliable and nice.
