BBB puts Seibold Plumbing & Heating at 42 years in business in Worcester, and the licences behind the name hold up: David Seibold's Massachusetts plumber's licence and HVAC licence are both active on the state registry. What customers have written is dated — four Google reviews from 2019 and 2020 — and it goes both ways. In December 2019 one customer had a water heater looked at and a replacement in and running within four hours; a May 2019 reviewer wrote simply that they "always come through." The two one-star accounts are both about what happened after the truck left. Earlier in December 2019, a homeowner wrote that a clogged sink was seemingly clear when the plumber finished, blocked again the next morning, and that they called expecting a return visit under the 30-day labor guarantee printed on the invoice. In January 2020, a customer who had a heat pump installed in place of an old AC called the crew punctual, clean and friendly, then wrote that they didn't stick around to make sure it was working correctly, and that it was not working right. The trade mix covers both halves of the name. BBB lists plumbing, heating, gas and oil, water heaters, boilers, drain cleaning and air conditioning, for homes and light commercial buildings; BuildZoom shows 30 projects and mechanical, HVAC and sheet-metal work under plumbing and gas permits. Its BBB grade is an A+, though the company is not accredited there. For a water heater, a boiler or a drain, this is a long-established, licensed Worcester shop. Before an install, ask what the 30-day labor guarantee on the invoice covers and who comes back if a fix doesn't hold, and ask them to run the new system with you before they pack up.
I hired Seibold Plumbing and Heating to install a heat pump to replace an old AC unit. The guys who came out were punctual, clean, and friendly. However, they didn't stick around to make sure it was working correctly when they left. It was not working right and I ended up having to crack open the manual and finish the job by setting a few dip switches on the unit myself. Took me about an hour and I gave that a pass since this tech is new and I suspect they don't install many of these. What I really have issue with is the soldering job was leaking refrigerant. It was leaking onto my basement floor in little drips. I called the owner who came out and spent all of 30 seconds with some meter tool and proclaimed it was not leaking. I wiped it clean as a whistle and the next day, more drips on my floor. I called him back and he said I was crazy. I called again and again and again. I give him credit for answering every time but he never offered to fix it. I ended up calling another company to redo the soldering connection which cost me about 600 bucks. This company does NOT stand by their work and I will never do business with them again and warn you not to either.
Came in and evaluated my water heater issue. Then brought in replacement unit back up and running in 4 hours.
Had a plumbing issue. Called this company, guy was punctual, worked on a clogged sink for an hour or so. Left with pipe seemingly clear. The next morning I discovered the same issue. I called expecting a return visit since their invoice has a 30 day labor guarantee. Instead got a call basically saying they did all they could and I would need a new pipe. Called another plumber who came and worked on the clog for a couple hours and cleared it 100%. So, basically wasted $175 here. Might want to white-out that 30 day guarantee if you don't stand behind it.
Always come through, even when other plumbes say it came be done
