Work With a Reliable Plumbing Company

HMS Team

Our Story

We are a family-owned business located in Manassas, Northern Virginia. The owners of HMS Plumbing, Diana and Herve, are both master plumbers. Herve is also a Master gas fitter and certified backflow prevention worker.

Diana and Herve are proud to be serving the plumbing needs of Northern Virginia residents and businesses alongside their dedicated group of plumbers and office staff.

Humble Beginnings

Herve has been in the plumbing industry since he was 16 years old and lived in Nice, France. He studied under his uncle who owned a small business.

In those days, plumbers in France were considered craftsmen, and it took years of schooling and supervised apprenticeship to be considered worthy to carry on the trade. He also learned the art of pipe bending, which is a traditionally used method of bending copper lines.

This method was not only used for aesthetic reasons: it also diminished the amount of fittings that could potentially leak in the future.

Work Experience

Herve worked for several well-known plumbing companies in Northern Virginia before opening HMS Plumbing. Coming from his background and education, it surprised him that most plumbers did not go to plumbing school and the companies they worked for didn’t require it.

He also believed that the craftsmanship and work ethic that is integral to the trade should be the sole focus of a plumbing company. The pressure on plumbers to sell, sell, sell made him uncomfortable. Quota systems and high-pressure sales techniques did not sit well with Herve. That was the driving force behind the decision of Diana and Herve to open HMS Plumbing in 2002.

HMS Office Team


Education and training are a necessity when it comes to performing plumbing services of any kind – whether it be water, sewer, or gas. We take that very seriously. We require all of our plumbers to go through our training course as well as state schooling and licensing.

We are a licensed plumbing contractor serving both Northern Virginia and parts of Southern Maryland. Our master plumber, Herve, started off his plumbing career in Nice, France when he was only 16 years old.

He received his master plumbing certificate after years of schooling in France. After moving to the U.S., he also received his master plumbing license in Virginia and Maryland.

We are not only certified to do plumbing, but we are also a licensed gas fitting contractor and certified to test and service backflow prevention devices.

We are also Fusion Pipe, WARDflex, and TracPipe certified in the state of Virginia. We are constantly adding new certifications and training to our repertoire to provide our customers with the best service available.


The Birth of HMS Plumbing

After years of unsuccessfully searching through several of the big brand plumbing companies in an effort to find a company he could call home, he and Diana decided to start their own plumbing service company in 2002.

Diana and Herve founded their company on several principles:

First: They were dedicated to personally providing their plumbing students with the same hands-on training Herve had received as a young plumber, in addition to sending them to an accredited plumbing school.

Second: Transparency is a critical part of our business model. We utilize a standardized price book for most plumbing tasks – as do many other plumbing companies. The difference with us is that we will quote prices over the phone, thereby saving the customer and our plumbers the time required for an on-site service call. It’s equally critical to HMS Plumbing to provide high-quality work at very reasonable prices.

Quality, transparency, and mentorship – that’s how we do things differently.
