## The honest read

Joseph A De Mella Plumbing is a residential and commercial plumbing and heating company serving Cambridge and the Greater Boston area, offering repairs, 24/7 emergency service and free estimates by its own account; the company says it's been in business 35 years.

Its lone rating on Google is 1 star, with no review text attached explaining what happened — with only that single data point on file, there's no way to tell if it reflects a pattern or a one-off.

Worth asking directly about that Google rating and lining up references before booking, since there's no customer account on file yet to say what a job with them actually looks like.

**Concerns:**
- Lone Google rating — a single 1★ with no review text
