Michael Grella Plumbing & Heating

When a heating or hot-water problem cannot wait, Michael Grella is often the person customers call. Recent homeowners describe same-day and Sunday responses, repairs to Navien boilers and water heaters, and a shower cross-connection diagnosed after two other plumbers had failed to fix it. Michael Grella Plumbing & Heating is based in Norwood and the company says it serves residential and commercial customers across Greater Boston and the South Shore. Customers consistently mention clear communication, clean work, fair or upfront pricing, and explanations they can understand. In a June 2026 review, a homeowner described heating-system service, a leak repair, and a faucet installation, praising the responsiveness and reliability. A July 2026 customer said Michael repaired a shower cross-connection the next day. Older reviews add depth: a 2023 homeowner described a Navien boiler restored within 30 minutes during frigid weather, while another described new heating and HVAC installations and two bathroom remodels completed in 2019 and 2022. A multifamily customer also described Michael correcting the programming on three Navien units so a recirculating-pump system delivered hot water immediately. There are two issues to discuss before scheduling. The Massachusetts registry lists both Michael Grella's individual plumber license and Michael Grella Plumbing and Heating LLC's company license as active, so confirm which entity and license will appear on the contract. Two one-star Google reviews from May 2022 describe a nearly $500 faucet visit and difficulty reaching the company; those accounts sit alongside many later positive reviews, but they make the estimate, service charge, and communication process worth confirming up front. Grella appears well suited to homeowners who need plumbing, heating, or high-efficiency Navien troubleshooting and value prompt, hands-on service. Ask for a written scope and price, clarify the responding entity, and confirm the arrival window before work begins.
