Shower Valve, Cartridge, and Drain Repair: Diagnosed Before We Quote
Shower repair usually means one of two very different problems, and mixing them up is how people pay for the wrong fix. Either the shower valve is acting up (a spout or head that won't stop dripping, no hot water at the shower, water that swings hot to cold on its own, or a diverter that won't send water up to the head), or the shower drain is clogged and pooling around your feet. You reach the Holdsy Plumbing team directly at (301) 834-2944, and Chase figures out which of those you actually have before quoting a thing. Owner-operated and insured means the person who answers the phone is the person who shows up, and there's no commission pushing a full shower tear-out when a ten-dollar cartridge is the honest fix.
Here's the part that's specific to where you live, and it drives most of the valve calls we get. Montgomery County water through WSSC runs moderately hard, and that hardness scales up the cartridge seats and the moving parts inside a shower valve, which is exactly why cartridges here wear out and start dripping sooner than the box promises. The other local pattern is age: a lot of the pre-1980 homes across Gaithersburg, Montgomery Village, and older Rockville still have an original single-handle valve body, and some of those brands are long discontinued. When the cartridge for one of those isn't made anymore, the honest answer is a valve body and trim replacement, not a repair, and Chase will tell you which side of that line you're on before he opens the wall.

Shower Valve Cartridge Replacement: The Fix for a Dripping Shower
A shower that drips from the head or spout after you shut it off is almost always a worn valve cartridge, not a failing shower. The cartridge is the part inside the valve that mixes hot and cold and seals the water off, and in our hard water its seats scale up and stop sealing, so a few drops keep coming through. Swapping the cartridge is a modest, contained repair on most valves, and it usually costs a fraction of what people brace for when they hear "shower valve."
The honest dividing line is whether the cartridge is still made. On a common brand with a valve body in good shape, a cartridge replacement is the whole job and you're done. On a pre-1980 single-handle valve whose cartridge is discontinued, or a valve body that's corroded, that's when it becomes a valve-and-trim replacement instead, and Chase will show you why rather than just quoting the bigger number. Not sure what brand you've got? Call (301) 834-2944 and describe the handle, or snap a photo of it.

No Hot Water at the Shower or Water That Swings Hot and Cold
No hot water at the shower when the rest of the house has plenty of hot water is a shower-valve problem, not a water-heater problem, and the fix is usually inside the valve. The two most common causes are a failed cartridge that's stopped mixing and a pressure-balance valve or scald guard that's scaled up and stuck. The tell is simple: if your kitchen and bathroom sinks get hot but only the shower runs cold or lukewarm, the heater is fine and the valve is the suspect.
"If every other tap in the house gets hot and only the shower won't, don't start with the water heater. Nine times out of ten it's the shower cartridge or a scaled pressure-balance spool, and that's a valve fix, not a heater fix."
Water that swings hot to cold on its own, or scalds you when someone flushes a toilet, points at the same family of parts. A pressure-balancing cartridge is supposed to hold your temperature steady when another fixture draws water, and when it scales up or wears out it stops doing that. Some valves also have a temperature limit stop that drifts over time, which is a quick adjustment rather than a part. Chase checks the cheap causes first, the limit stop and the cartridge, before assuming the whole valve. Shower gone cold on you? Call (301) 834-2944 and tell us whether your sinks still run hot.

Shower Diverter Repair: Water Won't Go Up to the Head
A shower diverter that won't do its job has a clear symptom: you pull the knob or lift the tab, the shower head should take over, but water keeps running out of the tub spout instead. The diverter is the little gate that redirects flow from the spout up to the head, and when it wears out it stops sealing, so the water takes the easy path down and out the spout.
Either way it's a repair, not a reason to redo the shower. Chase tells you on-site which type you've got and what it takes, and if it's the spout-mounted kind he can often handle it the same visit. Water still pouring out the spout when the shower's on? Get a free estimate and describe your handle setup, or call and we'll talk it through.

Clogged Shower Drain: The Short Version
A clogged shower drain is almost always a hair-and-soap-scum mat caught right where the drain tailpiece meets the trap, a few inches down. It builds slowly, the water pools deeper each week, then one day it won't drain at all. Most shower clogs clear with a hand auger or a short cable run once the strainer comes off, and we skip the caustic drain chemicals that sit on your pipes and do little to a solid hair mat.
That's the whole shower-drain story on this page, because a shower drain that keeps backing up or is really a main-line problem deserves the full treatment. For the deep version, the cabling, the camera scope, and the difference between a branch clog and a blocked main, see our clogged drain removal page. If it's just your shower pooling and nothing else in the house is backing up, call (301) 834-2944 and we'll clear it.

When Shower Repair Isn't the Right Call
Here's the honest version, because it saves you money. Not every shower complaint is a repair we should sell you, and a couple of them aren't shower problems at all.
- A brand-new drip you haven't tried tightening. If a handle or trim piece just started weeping and it's only a few months old, it may only need the fitting snugged or the escutcheon reseated. Worth a look before you pay for a cartridge you don't need.
- Weak flow at every fixture, not just the shower. If the shower is weak but so is every sink and tap, that's a whole-house pressure or supply question, not a shower repair. Fixing the valve won't change a thing.
- You want to gut and remodel the shower. If the tile's coming out and you want all-new everything, that's a renovation choice, and it's a fine one, but it's your call, not a plumbing necessity. We'll install what you've chosen, we just won't pretend a working valve had to go.
"We'd rather talk you out of a repair you don't need than sell it. A snug fitting or a cleared aerator beats a service call, and telling you that is how you call us back next time."
What we won't do is quote a valve replacement for a drip without first checking whether a cartridge fixes it. If your shower leak is showing up as a stain on the ceiling below, that's past the valve and into the wall, and it's a shower leak reaching the ceiling below situation worth catching early. Describe what you're seeing and we'll point you the right way. Call (301) 834-2944.

FAQ Common questions
Frequently Asked Questions
Answers below
Why does my shower drip after I turn it off? +
A shower that keeps dripping from the head or spout after you shut it off almost always has a worn valve cartridge, the part inside the valve that mixes hot and cold and seals the water. In Montgomery County's moderately hard WSSC water, the cartridge seats scale up and stop sealing, so a few drops keep coming through. On most valves a cartridge replacement is the whole fix and it costs a fraction of a fixture. The exception is a pre-1980 single-handle valve whose cartridge is discontinued, in which case it becomes a valve-and-trim replacement. Call (301) 834-2944 and describe the handle, or send a photo, and Chase will tell you which before quoting.
Why is there no hot water at just my shower? +
If your sinks and other fixtures get hot but only the shower runs cold or lukewarm, the water heater is fine and the problem is inside the shower valve. The usual causes are a failed cartridge that's stopped mixing hot and cold, or a scaled-up pressure-balance cartridge that's stuck. It's a valve repair, not a heater repair. Chase checks the cartridge and the temperature limit stop, which is a quick adjustment, before assuming the whole valve needs replacing. Call (301) 834-2944 and tell us whether your sinks still run hot, so he brings the right part.
How do I unclog a shower drain? +
Start by pulling the strainer or stopper and removing the hair-and-soap mat you can reach with your fingers or needle-nose pliers, since most shower clogs sit just a few inches down where the tailpiece meets the trap. A cheap plastic barbed drain tool clears a surprising amount of it. If that doesn't do it, a hand auger run down the drain usually catches the rest. Skip the caustic chemical drain cleaners, they sit on your pipes and do little to a solid hair mat. If the water still won't clear, or if the shower backs up when other fixtures drain, it's likely deeper than the branch line and worth a call at (301) 834-2944.
Can you fix a shower diverter that won't send water up to the head? +
Yes. When you pull the diverter and water keeps pouring from the tub spout instead of the shower head, the diverter has worn out and stopped sealing. There are two kinds. A pull-up diverter built into the tub spout is usually fixed by replacing the spout, a quick job we can often do the same visit. A diverter built into the valve itself, common on three-handle setups, is a cartridge or gate repair inside the wall. We test which type you have before quoting, because the price difference is real. Call (301) 834-2944 or use the contact form to describe your handle setup.
Is it cheaper to repair or replace a shower valve? +
Repair, in most cases. A dripping or temperature-swinging shower is usually a worn cartridge, and swapping the cartridge costs far less than replacing the whole valve. Replacement makes sense in two situations: when the valve body is corroded, or when the cartridge is discontinued, which happens on some original single-handle valves in pre-1980 Gaithersburg and Rockville homes. Chase checks whether the cartridge is still made and whether the body is sound before quoting, so you only pay for a valve replacement when it's genuinely the right call.
