Zero stars. BEWARE. Overcharging for sub standard work. The list of problems we've dealt with on our new home build (2024) caused by incompetent Masons Plumbing and Heating installation and "maintenance" is far too much to write in detail for this space, but everything we've had installed (heat pumps/water tank/in-floor heating & exterior vents) has cost us about $3.5k to fix, as well as multiple visits from professionals. We called Masons Plumbing twice to chat about our problems, asked to speak with the owner/s, but was never contacted back. We've moved on, found a locally well respected and knowledgable plumbing and HVAC businesses in Bridgewater and Lunenburg who have fixed our issues and explained how and why Masons installations failed. Masons Plumbing clearly doesn't care to address issues with good customers who put their faith and tens of thousands of dollars into their business. Find other options. There are a lot better out there.
