Montgomery and Frederick County
Whole-home filtration for Montgomery and Frederick County. Installed fast, priced fairly.
In Montgomery and Frederick County, it usually starts with one of these three. Each calls for a different fix, so we look at your water before we suggest anything.
A chalky ring inside the kettle, a film on the shower glass, spots on glasses from the dishwasher. Most of WSSC Water's Montgomery County area is served from its Potomac plant, whose 2025 tap analysis lists hardness at a yearly average of 154 mg/L.
Chlorine in a glass from the kitchen tap, or a whiff of sulfur when you run the hot water. Both usually start with the supply coming into the house, not with the faucet you are blaming.
Rust coloured marks in the sink or the tub, grit caught in the faucet screens, towels and shirts that come out of the wash looking tired. That points to what is dissolved in the water, not to how often you clean.
About Potomac Water Pros • Close to home
Potomac Water Pros works with households across Montgomery and Frederick County on the water that comes out of their taps. Some want the scale gone from the shower glass, some want a better glass of water from the kitchen, and some are on a well and want to know where to begin. We look at where your water comes from and what you are noticing, then suggest softening, carbon filtration, reverse osmosis, well treatment or a mix of them. You get a plain answer and a system sized to your house.

First we talk through what you are seeing at the taps. Then we tell you which system fits and what it costs. If you say yes, we put it in and show you how it works.
Tell us whether you are on city water or a well, and what bothers you about it, from the kettle to the laundry. That tells us where to start.
We lay out which system suits your house and your budget, and why. Ask as many questions as you like.
Once you pick a system, we install it, check that it runs properly, and walk you through the few things it needs from you.

Homes on a well get their own sizing and their own price.

This is one example setup. Yours gets sized once the assessment is done.
Don't see yours? Add it to your assessment request and we will answer it on the call.
We give you a call and talk through your water together. By the end you know which system we would fit and what it costs. The assessment itself is free.
The written price is the one you pay. If something about your house would change it, we tell you before any work begins.
At the spot where your water line comes in. That is often the basement, a utility room or the garage.
Floor space for the tanks, and enough room above to lift the cabinet lid and reach the bypass.
Keep the cabinet topped up. The setup notes explain it, and that is really all there is.
It does, sized another way. A private well shifts over the year, so it is set up differently from city water. We do both.
