Meet The Founder

20+ Years of Experience • Licensed Master Plumber & Gas Fitter in the State of New Hampshire

Hi, I’m Jeffrey Boisvert, a licensed Master Plumber and Gas Fitter in the state of New Hampshire. I started my plumbing journey in 2002 with my parents’ kitchen and bath company and later spent nearly 13 years serving as a police officer.

In 2021, I returned to plumbing and heating, gaining experience as an apprentice and lead technician before earning my Journeyman licenses and becoming Service Manager at LHR Plumbing and Heating.

​Using my experience from plumbing, heating, and customer service, I founded Thin Blue Line Plumbing and Heating. As a small, family-owned business, we’re dedicated to high-quality work, fair pricing, and excellent customer service.

Whatever you do, work at it with all your heart, as working for the Lord, not for human masters.” ~ Colossians 3:23

Our Happy Clients

Google - 5 Stars Rating

Truly the best plumbing service in NH, with fair rates and instant quotes. He was exceptionally knowledgeable, friendly (and even won over our black lab), punctual, and offered very affordable pricing. He took the time to thoroughly explain our home’s plumbing systems while conducting a detailed root-cause analysis of the issue. His quotes were clear and provided on the spot, and he answered every question without ever making me feel like a burden. He worked carefully, never rushed, and ensured I understood each step before moving forward. Outstanding service—I highly recommend him!
