Plumbing Done Right: Upfront Pricing, Fast Response, & Results You Can Trust.

STP Plumbing was founded by Master Plumber Steve Poirier with a simple mission: deliver five-star service with honesty, precision, and care. The name “STP” honors both Steve’s initials and his father’s legacy as “Steve the Plumber,” a strong influence on his career and values. When his father retired, Steve carried that tradition forward by building a company rooted in family, integrity, and true craftsmanship.


At STP Plumbing, we understand that plumbing problems can be stressful and disruptive — from sudden leaks to cold showers at the worst times. That’s why our team of licensed, certified plumbers is committed to fast response, clear communication, and upfront pricing with no surprises. We approach every project, big or small, with the same dedication to doing it right the first time and treating your home with respect.


Whether you need a repair, installation, or a full water filtration system, our goal is always the same: to provide tailored solutions that bring comfort, reliability, and peace of mind to your family. Based in Franklin, MA, STP proudly serves communities throughout Massachusetts and Rhode Island with professional service you can count on, every time.
