Grains per gallon. Scale, spots, and stiff laundry come from here. If it's high enough to bother you, that points to a water softener.

Water Quality Testing for County and Well Supply
Holdsy Plumbing's water quality testing in Gaithersburg, MD answers one question before you spend a dollar on equipment: what's actually in your water. Maybe the glasses come out spotty, the water smells off, or you just moved onto a private well and don't know what you inherited. We test hardness, iron, sulfur, and clarity on site, explain what the numbers mean, and only then talk about treatment. Call (301) 834-2944 and say whether you're on county water or a well.
Chase Holdsworth owns Holdsy Plumbing and does the work himself, and the honest position here is that we'd rather test than sell. A test can just as easily tell you your water is fine as tell you it isn't. If the result says your WSSC supply is moderately hard and nothing else is wrong, we'll say so and you keep your money. When the result does point to a real problem, the test decides which system fixes it, so you don't buy a softener for a smell a softener can't touch.

Water Quality Testing in Gaithersburg, MD
A water test in Gaithersburg means something different depending on where your water comes from, and that's the first thing we sort out. County supply through WSSC arrives already treated and fairly consistent, so a test here is mostly about confirming hardness and whether taste or chlorine is bothering you. Private wells are a different job entirely, because nobody treated that water before it reached your tap.
What we look at on site is practical: hardness in grains per gallon, visible iron or rust staining, a sulfur (rotten-egg) smell, sediment and clarity, and taste complaints you can point to. We're not running a lab; we're measuring the things that decide whether treatment makes sense and, if it does, which kind. When a well needs a certified lab panel for bacteria, nitrates, or something beyond what a field test reads, we'll tell you that plainly rather than guess. Call (301) 834-2944 and describe what you're noticing.

Well Water Testing in Montgomery County
Well water testing in Montgomery County is where a test stops being optional and becomes the only responsible way to start. Private supply out toward Damascus, Clarksburg, and Poolesville isn't treated by anyone before it reaches your house, and two wells a mile apart can read completely differently. One brings hardness plus iron; the next carries sulfur; a third looks clean until a wet spring changes it.
"On a well we test first every time, because the water writes the equipment list. Sizing a system off an assumption is how people end up with a softener fouling on iron it was never built to handle."
That variability is exactly why we won't quote a well home off the phone. Iron has to be treated ahead of a softener, not sent through it, or it shortens the resin's life considerably. Sulfur needs its own step. Sediment ahead of everything. The order of the equipment matters as much as the equipment itself, and only a test tells us the order. If the well's pressure or supply is also acting up, that's a good moment to look at well pump service at the same time so it's one diagnosis instead of two.
When a field test isn't enough
For anything a field test can't cover, bacteria or nitrates on a well that serves drinking water, we'll point you to a certified lab panel and help you make sense of the results. We won't pretend a hardness strip answers a bacteria question. Call (301) 834-2944 and tell us where your well is and what it's doing.

Test First, Then Decide on Treatment
The reason we lead with testing is simple: a softener, a filter, a conditioner, and a reverse osmosis system all solve different problems, and installing the wrong one means you keep the complaint and gain a maintenance chore. A test is the cheapest way to avoid that.
Here's how the common results map to a fix:
- High hardness, nothing else points to a water softener, sized to your grains and household. - Chlorine taste, sediment, or odor across the whole house points to whole-house filtration at the main. - A drinking-water concern about taste or dissolved solids points to reverse osmosis under the kitchen sink, not the whole house. - Well water with iron or sulfur points to targeted treatment ahead of any softener, which is why the water treatment plan always starts with the test.
Sometimes the result is the best news of all: your water is fine and you don't need anything. We'll tell you that too. Get a free estimate or call and we'll walk through what your numbers mean before anyone talks equipment.

When You Don't Need a Water Test
Testing is the right first move for most water complaints, but it isn't always the call, and it's worth saying so.
The honest version: if you're on county water and everything looks, smells, and tastes normal, you probably don't need us out to test it. Read WSSC's published report first. Where a test earns its keep is a private well, a new home you don't know the history of, a sudden change in taste or clarity, or visible staining you want pinned to a cause before you spend on equipment. If you're not sure which bucket you're in, call (301) 834-2944 and we'll tell you honestly whether a visit is worth your time.

FAQ Common questions
Frequently Asked Questions
Answers below
How do I know if my water is hard? +
The everyday signs are scale on fixtures and kettles, spots on glassware even out of a good dishwasher, soap and shampoo that won't lather, and stiff laundry. Those tell you hardness is present; a test tells you how much, measured in grains per gallon. County water from WSSC generally runs 7 to 11 grains, which is moderately hard. Private wells in the upper county are frequently harder. We can test your actual number on site before you decide whether a softener is worth it.
What contaminants are in Gaithersburg water? +
It depends on your source. County supply through WSSC arrives treated and consistent, and the usual complaints are moderate hardness and a chlorine taste rather than contaminants. WSSC publishes an annual water quality report for the county system. Private wells around Damascus, Clarksburg, and Poolesville are untreated, and what they carry varies well to well: hardness, iron and rust staining, and sulfur (a rotten-egg smell) are the common ones. For bacteria or nitrates on a drinking-water well, a certified lab panel is the right tool, and we'll point you to one.
How much does a water quality test cost? +
It depends on what you need. A basic on-site check of hardness, iron, sulfur, and clarity is different from a certified lab panel for bacteria or nitrates on a private well. We'd rather look at your situation and quote honestly than post a number that doesn't fit your case. Call (301) 834-2944, tell us whether you're on county water or a well and what you're noticing, and we'll tell you what testing actually makes sense and what it involves.
Do I need to test my water if I'm on WSSC county water? +
Usually not, if you have no taste, smell, or staining issue. County water is already treated and fairly consistent, and WSSC publishes an annual report for the county supply. A test earns its keep when something changes or when you want a hardness number before buying a softener. If everything looks and tastes normal, you probably don't need us out.
Should I test my well water? +
Yes. Private wells aren't treated by anyone before the water reaches your tap, and two wells close together can read very differently. Testing is the only responsible way to know whether you have hardness, iron, sulfur, or something that needs a certified lab, and it decides both the equipment and the order it goes in. It matters most on a new home whose well history you don't know, or after a sudden change in taste or clarity.
Will a water softener fix my rotten-egg smell? +
No. That smell is typically hydrogen sulfide, and it needs treatment aimed at sulfur, not hardness. Sending it through a softener won't remove it and can foul the resin. This is exactly the kind of thing a test settles up front, so you treat the actual problem instead of guessing.
