Brian Donnelly replaced our water holding tank and replaced some poorly chosen piping installed by prior owner. He also installed a new outdoor faucet. He also did a really nice job on some projects in our old farmhouse too. He keeps his appointments and does good work. 100% recommend!

Stripe D. Canann NH

Brian and his apprentice were super quick and helpful in a semi-emergency situation for us last year.

Kathryn R. NH

Hanover Plumbing & Heating is a top notch company. I was recently in need of some plumbing repairs before a home inspection and Brian and his apprentice were there to do the job quickly and efficiently. Thank you!

Matt N. Lebanon NH

Call Hanover Plumbing & Heating if you are in need of a reliable and excellent plumber. Brian Donnelly is the man for the job. I have had three projects done recently and he did a fabulous job. When you work on an old house, you have to be up for the challenge and he is. Prompt response to calls and texts and he cleans up the job site after, removing the old stuff, boxes, etc. Pipe work is beautiful.

Elaina D. Lebanon NH

The best around!

Linda M. NH

Thank you for the excellent work you have done for us. You all have been patient, kind and thorough. Worth every penny!

Johnathan T. Hartford VT

We have worked with Brian and he is great. Most recently he did work in an old house for a client of ours. The first plumber who looked at it said he could not do it. Brian jumped right in and took care of it. From easy to complex and cringe worthy projects, Brian is willing to do them.

Holly W. Canaan NH

I have nothing but GREAT things to say about Brian Donnelly and Hanover Plumbing and Heating. My water heater died Sunday. I called and contacted 3 other plumbers who wouldn’t even give me an estimate because they were only serving their “current clients”. Brian gave me an estimate quickly and was at my house the next day. He’s got the latest tools, and he got the job done quickly and expertly!

Donna D. NH

Plumbing problems cause so many inconveniences to our business, but Hanover Plumbing and Heating is a real savior! Thank you for the fast assistance!

Coffee Shop NH

Great service & highly recommend Hanover Plumbing & Heating! Brian was able to really come through in replacing a boiler system when another company really dropped the ball. From the great scheduling and frequent updates received from Lisa to the professional, expedient & honest service received. Brian is a true professional with a high display of commitment to customer service! Thank you!

Diane M. Enfield NH

Once again Brian came through and saved the day! Hanover Plumbing & Heating has been such a great business to deal with! Professional, responsive and to the point!

Keith B. Enfield NH

Always a successful visit.

Pete & Amy T. Canaan NH

The service was performed promptly and the technician was friendly and kept us informed throughout the entire call. And it should also be noted that this was done on an extremely cold Saturday during a snowstorm. Highly recommend for your next plumbing and heating project.
