**Rating: 3.3/5** (low confidence) — from 2 reviews across 4 sources.

## The honest read

Corso Plumbing & Heating handles plumbing and heating work from Haverhill across Massachusetts and New Hampshire. Its website says the company has been in business for 20 years and takes on commercial, multi-residential, healthcare, industrial, and design-build projects.

Two 2025 Google reviewers mention easy delivery access and a driver giving money to a homeless man; the small public review set offers little detail about completed plumbing jobs. BuildZoom lists 112 permitted projects, with about 15 in the past three years and a typical permit value near $22,500.

The Massachusetts plumber license is registry-verified active. BuildZoom also lists several license entries, including an older master-plumber entry it says was cancelled at one point, so confirm which credential applies to the person and project you are hiring.

Corso is a fit to consider for commercial or multi-unit plumbing and heating work; ask for recent references for your project type, the scope of the design-build process, and the license details on the contract.

**Strengths:**
- Permitted projects — BuildZoom lists 112 permitted projects
- Commercial scope — website names healthcare and industrial work
- Active license — Massachusetts plumber license is registry-verified active

**Concerns:**
- Thin job detail — two Google reviews do not describe completed plumbing work
- Credential details — BuildZoom lists multiple license entries
