Wilco Plumbing & Heating

Wilco Plumbing & Heating works out of 145 Stedman St in Chelmsford, but its permits are almost all filed a few miles north in Lowell: bathtubs, kitchen sinks, water heaters, backflow devices, boilers and gas ranges, across single-families, three-deckers and the occasional storefront. Forty-nine permitted projects is a real body of work. It is also mostly older work — the permits shown run 2015 through 2020, with one job in 2025. The licensing picture is what to press on. BuildZoom marks its licence entry "Unable To Verify", says it could not confirm anything with the licensing board, and scores the company 0 for that reason alone. That is a directory failing to confirm, not proof of a problem — but it does mean nobody has checked. Nobody has left a review either, on BuildZoom or anywhere else reached here. Before hiring, ask for the current Massachusetts plumbing or gas fitting licence number and verify it yourself with the state board, and ask for two recent customers you can phone.
