Experienced and Equipped Plumbing Contractor in the DC Metro Area

Backflow Preventer preventing water from escapingOur experience providing plumbing solutions to the DC Metro area for over 10 decades has allowed us to grow and change with the many advancements made to plumbing systems and technology.  As these improvements are made, W. L. Gary Company updates its training and technology to remain a premier plumbing contractor in the Washington, DC area. Backflow prevention and certification, repairs and installations of plumbing fixtures and piping systems, bathroom renovations, repairs or upgrades to water heaters, along with drain and sewer cleaning, are all plumbing services that we have been providing for years.  Technology advancements are enabling us to offer more efficient options for our customers, such as low-flow bathroom fixtures, high efficiency water heaters, and progressive methods for troubleshooting issues or installing updated systems.

plumbing services: video inspection and pipe cleaning (before and after)As a long-time plumbing company in the DC Metro area, customers call on us to use our knowledge and advanced technology to navigate the older plumbing systems that still remain in the city’s infrastructure.  Back-ups in plumbing or sewer systems are often an unpleasant surprise that result in costly cleanup and repair.  Using our video-inspection equipment, we can explore the cause of consistent sewer issues, find the source of a back-up, or provide our customers insight into what is beneath a property before you make an investment.  When we discover the cause of the issue, we’re able to use in-house equipment, such as our hydro-jetting tools to break down the debris, roots, or other objects to alleviate the problem.  For certain customers, they’ve found that regularly scheduled cleaning is the way to offer themselves, or their tenants, peace of mind that their plumbing systems won’t be giving them any unwanted surprises.  With a Plumbing Maintenance Agreement, we will keep track of the cleanings and contact you to find the most convenient time for you for the next one.

Pipes aren’t the only part of your plumbing systems that need attention.  Pumping and cleaning grease traps and ejector pits on a regular basis is key for their optimal operation.  Maintaining the pumps in these systems is also imperative to ensure they can do their job and pump sewage, waste, and water out and away from areas it could damage.  We have a wide range of pumping and cleaning tools that allow us to service any size pit or trap.  From a push cart pumper to a 3600 gallon pumping truck, we can handle any size job.

When you are looking for a plumbing services company in Washington, DC, Maryland, or Northern Virginia who is licensed and insured with highly trained plumbers and the most high-tech equipment available for plumbing systems, contact W. L. Gary Company – 202.723.0676  

Plumbing Tip


Leaking Toilet

Think your toilet tank might be leaking?  Put a couple drops of food coloring into your toilet tank.  Wait about 15 minutes without flushing.  If the food coloring enters your toilet bowl, your tank is probably leaking.  Don’t forget to flush your toilet after the 15 minutes to rinse out the food coloring.
