Master Chimney Sweepers

Master Chimney Sweepers is a Natick outfit that homeowners across Greater Boston keep calling back year after year — reviewer after reviewer mentions they've used the company "for years" or say service was excellent "as always." With more than 650 written reviews since 2022 and a Google rating built on 1,274 ratings, this is a business with a long, consistent history, not a handful of five-star plants. What comes up again and again isn't just that the work gets done — it's how it gets done. Technician after technician is described walking customers through what they found: explaining a chimney's construction, showing photos of interior flue liners and exterior brickwork, laying out options before doing anything, and answering questions patiently. One 2025 review described a 70-year-old flue system that had been slowly failing, and said the company hustled to special-order piping and prioritized getting it replaced rather than letting it drag on. Another, from 2024, described an emergency call after a water heater flue failed, with a technician at the door the next morning. The company is a BBB Accredited Business with an A+ rating and is CSIA Level 1 and 2 certified, and Best Pick Reports rates it 5.0★ from 688 ratings — both independent of its own review platforms. The one real blemish in an otherwise strong history is a single 2★ review from this spring describing a film of soot left on a mantel and windowsill after a cleaning — the reviewer, a long-time customer, called it the only time in years that kind of mess was left behind. A couple of other reviewers separately note the company isn't the cheapest option, though both go on to say the work justified the cost. Worth calling for anything chimney-related — sweeping, inspections, relining, damper or masonry repairs — especially if you want someone who explains what they're finding rather than just doing the work and leaving. Ask about pricing up front if cost is a concern, since a few reviewers note it runs higher than some alternatives.
