"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"Can't say enough good things about Whalen Plumbing and Heating. Our tankless water heater was giving us inconsistent temperatures and error codes, and they made the fix painless. They showed up on time, asked what we'd noticed before touching anything, and clearly know these units inside and out. They flushed and descaled the heat exchanger, cleaned the inlet filter, and checked the venting and connections, explaining everything in plain English with no pressure to upsell. They were respectful of our home and left the area cleaner than they found it. Pricing was fair and matched the quote exactly. Since the visit, our hot water has been steady and the unit runs quieter than it has in a long time."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."

"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."

"Outstanding customer service from start to finish. The plumber was knowledgeable, respectful, and left everything clean after the repair."

"My gas water heater was leaking and starting to get a bit old... so I needed a replacement. Boston Standard gave me an estimate after emailing them a few photos of my existing setup, and came out to replace it the next morning. Their estimate came in lower than another company I looked at by a fair amount. They also gave me a discount on a scratched water heater they had on hand that another customer rejected. The were prompt, professional, and got the job done quickly. I will absolutely hire them again for my plumbing needs."

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."
