## The honest read

AA Zack Plumbing is a small, owner-operated Brookline plumbing and heating outfit; the company says on its own site that it's been run since 1986 by Isaac, who describes himself as a master plumber.

The reviews, though few, describe fast, careful diagnostic work. In a 2021 review, a homeowner said AA Zack found the real cause of a toilet that had been leaking into a downstairs apartment for years — every previous plumber had just replaced the wax ring, when what was actually needed was a new flange — and fixed it in 45 minutes. In a 2025 review, a customer described emailing on a Sunday morning about a dead water heater; the plumber called back that afternoon, was on-site within 10 minutes, spent over half an hour tracing a tangle of water lines, and returned the next morning with a new water heater running within two hours. Other reviews describe a callback within minutes of a voicemail and arrival as promised in 30 minutes, plus a tankless water heater install that beat two competing quotes on price.

There isn't much of a review record to weigh beyond these five, so it's worth confirming current licensing and getting a written quote before the work starts.

**Strengths:**
- Sharp diagnosis — found what other plumbers missed on a chronic leak
- Fast response — same-day calls, on-site in 10 to 30 minutes
- Competitive pricing — beat two other quotes on a water heater install
