Find a Participating Contractor
For your convenience, Columbia Gas of Massacusetts makes available a list of independent plumbing and heating contractors who are enrolled in our Participating Contractor Program*. These contractors are qualified to service, install or replace natural gas equipment and interior gas lines.
* The contractors listed are not agents or representatives of Columbia Gas of Massachusetts and Columbia Gas of Massachusetts does not guarantee or warranty the work of the listed contractors. At the time contractors are enrolled in our program, they must demonstrate that they are licensed and insured. You are free to choose other contractors and do not have to choose a listed contractor. We suggest you obtain at least three estimates before making your decision.
