    I have had the privilege of using Donnelly’s for several large and small projects all of which they have excelled in service. I will never use another company to handle my plumbing or HVAC projects. I needed the gas line behind my new stove shortened so that it would sit flushed against the wall. Dylan was great. He came for the initial assessment a few days prior and returned to complete the project. Dylan was on time and had a pleasant attitude. He was super quick with changing out the line. Thanks Donnelly for another pleasant experience.

    I appreciate his candor and respectfulness with which he does his job. I highly recommend Donnelly’s to anyone with plumbing needs. Nicholas Romanowski was outstanding. I‘ve used him before and I would use him again N.M.
