Water Softener & Filtration Installation in Frederick, MD
Frederick homes get hard water from City of Frederick. We soften it, remove the disinfectant and polish your drinking water for $2,499 installed.

What is in Frederick's water
Frederick is the hardest-water city we serve. The city blends Potomac, Monocacy and reservoir water in a limestone valley, and county wells run harder still. Scale on fixtures and inside water heaters is the number one call, so a properly sized softener is the priority here.
Seasonal changes
Check the city's annual report.
Lead and older plumbing
Downtown Frederick has 18th and 19th century housing. Lead does not come from the treatment plant.
PFAS: Ask for the latest city PFAS monitoring results. Reverse osmosis at the kitchen tap addresses PFAS regardless of source.

Homes in Frederick
Frederick ranges from 18th century downtown rowhouses to 2010s subdivisions in Ballenger Creek and Urbana. Downtown installs need care with old plumbing and tight cellars; the newer homes are quick basement installs.

Frederick water questions
How hard is the water in Frederick?
Frederick is served by City of Frederick Water. We expect about 6 to 12 grains per gallon, which is hard. Frederick sits on limestone geology and blends Monocacy water, so hardness is expected to run higher than the Potomac-only utilities. Confirm with the city report.
Does Frederick tap water contain chloramine?
We confirm the disinfectant from the utility's latest report before specifying carbon media for a Frederick home. Disinfectant type not yet confirmed from the city report.
How much does a water softener cost in Frederick?
$1,899 installed for a metered softener with catalytic carbon, or $2,499 with an under-sink reverse osmosis system. That covers equipment, a licensed plumber's installation and startup for a standard install; we quote any extras before booking.
Do you install in Frederick townhomes and condos?
Townhomes, yes, usually with a compact single-tank softener in the utility closet. Condos where the building supply cannot be modified get an under-sink reverse osmosis system, which handles drinking water taste, lead and PFAS without touching shared plumbing.
Is Frederick water safe to drink?
Yes. City of Frederick meets federal and state standards, and we will never claim otherwise. A home system addresses comfort (hardness, disinfectant taste and smell) and, at the kitchen tap, contaminants that enter from home plumbing such as lead.
