Even clear-looking water can contain contaminants that affect taste, safety, and your family’s health. Across Maryland, Washington D.C., and Northern Virginia, homeowners often face a variety of water quality challenges — whether from municipal supplies or private wells.
At National Water Service, our mission is to give you clean, safe, great-tasting water — backed by over 45 years of trusted experience.
We start with a comprehensive water test. Our specialists analyze your tap or well water to identify exactly what’s in it — from minerals and bacteria to pH imbalance or chemical contamination.
You’ll receive a detailed water analysis report explaining what was found, how it affects your home and health, and what solutions are best for your specific water problems.
We design a personalized water treatment plan using non-proprietary, top-of-the-line systems built to last.
That means:
No locked-in service contracts
No proprietary parts
Only transparent, long-term water solutions
All installations are handled by our certified water treatment technicians, who bring decades of hands-on expertise to every job.
Your water system works best with regular care. We offer yearly inspections and maintenance to keep your equipment running efficiently, ensure filters and media are replaced on schedule, and verify that your water quality stays perfect year after year.
Our annual service plans help protect your investment and keep your home’s water clean, safe, and reliable — the National Water Service way.
