Corso Plumbing & Heating, Inc

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.
