The basics

How water filtration works

Water filtration improves the water coming into your home by removing what you do not want in it. A whole-house system treats every tap at the point where water enters, while under-counter and reverse osmosis units polish drinking water right at the kitchen sink. A water softener tackles hard water specifically, swapping the calcium and magnesium that cause scale and spots for softer water that is easier on your skin, fixtures, and appliances. The right setup depends on what is actually in your water, which is why we test first, then size and install a system built for your home.

Catch it early

Signs you need water filtration

If any of these sound familiar, a quick water test will tell us exactly what to fix.

Spots and scale on fixtures

White, crusty buildup on faucets, glasses, and shower doors is classic hard water.

Dry skin and dull hair

Hard water leaves a film that dries out skin and hair even after a good shower.

Bad taste or odor

A metallic, chlorine, or rotten-egg taste or smell means something worth filtering out.

Cloudy or discolored water

Sediment, rust, or cloudiness points to filtration your home is missing.

Stiff laundry and faded colors

Hard water makes detergent work harder and wears fabrics out faster.

Appliances failing early

Water heaters, dishwashers, and ice makers fail sooner when scale builds up inside.

Tired of hard water? Let's get your water tested.

Know your options

Types of water filtration

We help you pick the right system for your water, your home, and your budget.

Whole-House Filtration

Treats every tap at the point of entry, for cleaner water throughout the house.

Water Softener

Removes the minerals that cause hard water scale, protecting your fixtures and appliances.

Reverse Osmosis

Multi-stage filtration for the purest drinking and cooking water at the kitchen sink.

Built for Maryland water

Why this matters here

Much of Montgomery and Frederick County has hard water, and many homes on private wells deal with extra sediment, iron, or sulfur. Clarksburg, Damascus, and Poolesville homeowners especially notice it. The right filtration or softener protects your plumbing and appliances and makes everyday water better to drink, cook, and bathe in.

  • Get your water tested so you treat the real problem
  • Match the system to your water, not a one-size-fits-all box
  • Change filters and service softeners on schedule
  • Protect your water heater and appliances from scale

I had an absolutely wonderful experience with Clarksburg Plumbing LLC, and especially with Seth. From the moment he arrived, he was professional, respectful, knowledgeable, and quite frankly, a breath of fresh air. I was extremely nervous about the situation because my leak was below the main water shutoff valves, and the water had to be turned off at the street. Seth immediately put me at ease and assured me that everything was going to be okay. Rather than just putting together a temporary solution, he wanted to make sure he ordered the exact parts needed to do the job properly. Seth told me he expected to have the correct part and be able to return on Wednesday to complete the repair. On Tuesday afternoon, the office called to let me know the part had arrived and confirmed that Seth would be back Wednesday morning between 8:00 and noon. Seth was at my door at 8:10 AM! I was genuinely impressed. He completed the repair carefully, explained everything he was doing, and was extremely conscientious about properly turning the water back on, opening the faucets in the house, and making sure everything was working exactly as it should. What impressed me most, though, was Seth himself. He has a wonderfully calm, professional demeanor that made a very stressful situation so much easier for me. I sincerely appreciate the care he took with my home and the respect he showed me throughout the entire process. Clarksburg Plumbing is very fortunate to have someone like Seth representing their company. I would absolutely recommend them and Seth!!

I had a great experience with Tyler when he came out to replace our toilet flushing system. From start to finish, Tyler was incredibly courteous, professional, and knowledgeable. He walked me through what needed to be fixed, answered all my questions patiently, and completed the job efficiently. It’s rare to find such high-quality service and attention to detail. Everything is working perfectly now, and he left the work area completely clean. I highly recommend Tyler for any plumbing needs!

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 wanted to add a new review but I could not so I am editing my previous one. I had to use Clarksburg Plumbing again today and like last time, they were exceptional. I was fortunate enough to have John and Madeleine as my service technicians. I will always request them going forward. They are kind, professional and knowledgeable! I am sure the company knows how fortunate they are to have them as part of their team!

We thank Clarksburg Plumbing again for superior, high quality and friendly service! ----- Clarksburg Plumbing visited us last week to repair an external spigot that had been leaking. The work involved creating a little inside access panel. Within and without, a nice, neat job by Charlie and his understudy apprentice, Chris. Problem solved and happy campers here! ----- UPDATE: Plumber John Brown presented himself on time and got right to work replacing my Mom's ancient leaky kitchen faucet with a new store-bought one that I provided. During the process, Mr. Brown detected and showed me two other problem areas contributing to the water leaks: a cracked drain pipe and then rusted threads on the sink trap. He efficiently and expertly repaired all three elements to our full satisfaction. Plus, John is a super nice guy, completely honest and classy enough to laugh at all my corny jokes! The next time you need any plumbing work in your home or business, I strongly endorse John Brown and anyone on the Clarksburg Plumbing team! UPDATE 2: John and his understudy Maddie visited, and quickly solved the problem of a pinhole leak in copper tubing leading from our hot water heater. He advised us on other plumbing needs, for which we have scheduled and will otherwise follow-up. Thank you Clarksburg Plumbing for your top quality people - John Brown in particular - and performance.

Thank you to Seth, who came on Wednesday and fixed one of our two toilets and fixed our primary bedroom shower. And thank you to Charlie, who came today and replaced our other toilet and replaced our garbage disposal. You are both lifesavers! Our weekend (and going forward) will be MUCH nicer now that we can use our bathrooms (and garbage disposal) again. Highly recommend Clarksburg Plumbing.

GREAT service and expertise! John and Maddie just installed a water filtration system to our home. The process took one day to install and then they came back from the 48 hour install period to ensure everything was working well. John was familiar and knowledgeable about the water system we bought. Maddie and John kept our space clean, clearly explained how to ensure longevity for our system to last, and the difference it will make in our home. We appreciate their hard work and professionalism. This is our second time using Clarksburg plumbing. We would highly recommend their company to our family and friends.

Franklin and his crew showed up promptly and communicated great with us to help limit disruption with the tenants at 4 of our building. Unfortunately for us a second water main leak occurred the day before. But luckily for us they were able to stay on site another 2 days and knock the second one out, even staying till 8pm to find the line and get it repaired. These will be the guys I request for our next time needs

Seth and Brady did a fantastic job replacing our water heater. They were professional, courteous, and detail oriented. They arrived on time and did careful, clean work all the way through. We have worked with Clarksburg Plumbing on smaller items before this and would be very happy to utilize their services in the future, as well.

Good questions

Water filtration FAQ

What homeowners ask us most about filtration and softeners.

They solve different problems. A softener removes the hardness minerals that cause scale and spots, while a filter removes sediment, taste, odor, and contaminants. Many homes benefit from both. We test your water and recommend only what you actually need.

Reverse osmosis pushes water through a fine membrane to remove dissolved solids, leaving very pure, great-tasting water. It is usually installed under the kitchen sink for drinking and cooking water.

It depends on the system and your water, but most point-of-use filters are changed every 6 to 12 months and whole-house cartridges on a similar or longer cycle. We set you up with a schedule and can handle it for you.

Yes. Softer, cleaner water is gentler on skin and hair and prevents the scale that shortens the life of water heaters, dishwashers, and faucets.

Absolutely. We repair and maintain filtration systems and softeners, including ones we did not install, with filter changes, sanitizing, and part replacement.

We recommend it. A quick water test shows hardness, sediment, and what is causing taste or odor, so we size the right system instead of guessing. This is especially important on well water.

Yes. We are fully licensed and insured, every technician is background checked, and we serve Clarksburg, Gaithersburg, Germantown, Damascus, and the surrounding Montgomery and Frederick County area.

Treat it as urgent. Leave the home, do not flip switches or light anything, and call your gas utility’s emergency line from outside, then call us. We handle gas line leaks and repairs 24/7.
