Plumbing built for how Gaithersburg actually lives

Gaithersburg is one of Montgomery County’s oldest and largest cities, and it has just about every kind of home under one name. There is the historic core of Olde Towne near the old B&O railroad station, the sprawling planned community of Montgomery Village, the walkable New Urbanist streets of Kentlands and Lakelands, and brand-new mixed-use living at Crown and Rio Lakefront, all strung along the I-270 life-sciences corridor.

Almost all of Gaithersburg is on WSSC public water and sewer, so the plumbing here is less about wells and more about age and density: original supply lines in Olde Towne, fifty-year-old systems in Montgomery Village, 1990s fixtures and water heaters in Kentlands and Lakelands reaching the end of their life, and the shared stacks and shutoffs of townhomes and condos. We know every one of these situations, because we work in them every week.

What we see here

Common plumbing issues in Gaithersburg homes

The age and type of your home tells us a lot about what is likely going on.

1

Aging supply pipes

Older Olde Towne homes and 50-year-old Montgomery Village systems often have original galvanized or polybutylene lines due for repiping.

2

End-of-life heaters & fixtures

Kentlands and Lakelands homes from the 1990s are now hitting the age where water heaters, valves, and faucets start giving out.

3

Townhome & condo plumbing

Around Crown, Rio, and the Village, shared stacks, tricky shutoffs, and high-rise pressure call for a plumber who knows the setup.

4

Hard water & scale

Like the rest of the county, Gaithersburg water leaves scale that shortens the life of heaters and fixtures.

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber!

I needed a water valve installed for my new fridge and a new faucet installed in upstairs bathroom. Seth was amazing. He came out and really listened to me and my concerns. We even called the company that was going to deliver my new fridge so he would have a better understanding of what he needed to do his job. It made me feel at ease with the whole process. He is even coming back later in the week to install new fridge once it’s delivered. I will absolutely call them again.

Amazing experience with Clarksburg Plumbing LLC! Our well pump needed replacement. Seth showed up right on time, was very professional, knew what he was doing and pricing was fare (they showed me all estimates upfront and explained everything). Any future plumbing needs and Clarksburg Plumbing will be my first call. I’ll also ask for Seth by name if I can get him!!

We had a pinhole leak suddenly appear in our outdoor hose bib, and Clarksburg Plumbing was able to provide next-day service, which we really appreciated. Our technician, John Brown, arrived right on time after giving us a 30-minute courtesy call. John quickly diagnosed the problem, explained everything clearly, and provided an accurate assessment of what needed to be done. He completed the repair in under two hours, and the quality of his work was excellent. Before leaving, he even took the time to share some helpful tips on how to prevent similar issues in the future. John was friendly, professional, knowledgeable, and efficient from start to finish. We couldn’t have asked for a better service experience. I highly recommend Clarksburg Plumbing and especially John Brown for anyone needing reliable, high-quality plumbing work.

Cris and Franklin from Clarksburg Plumbing did incredible work at our home fixing an underground water service leak. They encountered complications but went to plan B efficiently and skillfully and got the job done well and in a timely manner. They also answered all our questions patiently and taught us a lot of why they made the decisions they made. We are very pleased with their work and plan to recommend them and all of Clarksburg Plumbing to our friends and neighbors.

We had a clog in our septic line. The Clarksburg Plumbing crew located the troublesome area using a camera and then removed the clog and tested the line. They then remounted the toilet with a new wax ring and cleaned the area. Overall, a great experience!

Seth was absolutely amazing! He was very courteous and knowledgeable about his profession. He arrived on time and worked the entire time. He kept me in the loop the entire way as to what he was doing. He diagnosed two leaks within our toilet system and readily fixed them. Clarksburg Plumbing should be honored to have such an amazing employee as him.
