Shamrock Chimney is a high-volume Worcester chimney sweep, cleaning, and repair company with 551 reviews on file since 2021 — one of the largest review counts of any chimney company in the area. But its Better Business Bureau profile tells a very different story: an F grade with 22 complaints on file, a serious mark for a business this size. Recent reviews are overwhelmingly five stars and describe a consistent, thorough process — camera inspections, before-and-after photos, detailed written reports, and technicians who explain what they find rather than pushing extra work. In a 2025 review, a second opinion from Shamrock found only minor repairs were needed on a chimney another company had recommended fully rebuilding, saving the customer thousands. Named-technician reviews — Mike and Kevin in a 2025 review, Frank in a 2024 review — describe specific, satisfactory flue liner and cap repairs. That said, a long, consistent thread of serious complaints runs alongside the praise, spanning 2022 through 2026. In a 2022 review, a customer said a new chimney liner left their house filling with smoke, that a repair attempt two months later didn't fix it, and that the company removed their damper and never replaced it. In a 2025 review, a customer described roof slate left dangling because it was 'unsafe to put back on' — it fell off the roof days later. Multiple reviews from 2023, 2025, and a recent one in March 2026 describe repeatedly missed or rescheduled appointment windows, in one case three missed windows within a single week. A 2024 review explicitly cites the BBB F rating and describes a leak the company allegedly caused on a job routed through Angi's dispute-resolution service. Worth noting directly: a large share of the five-star reviews from July 2026 are unusually uniform in structure and generic in detail for a business this size, which sits awkwardly next to the specific, credible complaints on record and the F BBB rating — reason enough to treat the recent wave of praise with some caution rather than as proof the underlying issues are behind them. Given the F BBB rating, the pattern of specific safety- and reliability-related complaints spanning years, and questions about how representative the recent review surge really is, this is a company where a homeowner should get everything in writing, ask directly about past complaints, and consider a second opinion on any significant repair recommendation.
I love that they provide a detailed report after the service with pictures. It’s one thing for someone to tell you something is wrong, but it’s another to actually see it. When he showed me the picture of the crack in the crown, I knew exactly what needed to be fixed. They patched it up perfectly and I feel so much better knowing water isn’t going to get in there and freeze over the winter. I’ve already referred them to my neighbors on our block. It’s great to have a local company that does such top-notch work.
This was my first time using Shamrock and I will definitely be back. They were super responsive, showed up early, and did a fantastic job cleaning out years of soot and creosote. My fireplace drafts so much better now and the whole house smells fresher.
If you need any kind of chimney service, just call these folks. They are honest, skilled, and actually care about their customers. We have had them do cleaning, repairs, and even a full inspection, and every time they have been excellent. Trustworthy company through and through. 🌟
We had a minor chimney fire scare and they came out the very next morning to inspect everything. Thankfully no damage, but they did a deep clean and gave us great tips on preventing buildup. So relieved to have a safe chimney again. These guys are real pros.
They came recommended by a neighbor and now I see why. The whole process was smooth, from booking to the final walk-through. The tech even showed me a video from the camera inspection so I could see the inside of my chimney. That was really cool and reassuring.
