Shower Repair
A dripping shower valve wastes water and signals a failing cartridge.
Wes repairs shower valves, diverters, showerheads, and pans without unnecessary demo.
What shower repairs involve
Valve, diverter, showerhead, or pan.
A shower that drips from the showerhead when the valve is closed has a worn cartridge inside the valve body. The cartridge controls hot and cold mixing and shuts off flow when the handle is closed. A worn cartridge lets water seep past. Replacement requires removing the trim and cartridge from inside the wall, not pulling tile.
Cartridges here do not usually wear out from use. They scale up. Front Range water is hard enough that calcium builds on the sealing surfaces until they cannot seat, which is why a shower in Littleton drips years before the same fixture would in a soft water town. It is also why a cartridge that has not moved in a decade sometimes needs a puller. Forcing a stuck one cracks the valve body and turns a one hour job into opening the wall.
A shower that is scalding on one setting and freezing on another is a different failure. Either the pressure-balancing spool inside the valve has seized, so it no longer compensates when someone flushes a toilet, or the scald guard limit stop is set wrong. The limit stop is a small adjustable collar under the handle that caps how far toward hot you can turn. Set too conservatively, the shower never gets properly warm and people blame the water heater. Wes checks the cheap thing first. Get it fixed.
One more that gets misread constantly: water coming out of the tub spout while the shower is running. That is a worn diverter, not a valve problem. On a tub and shower combination the diverter is usually in the spout itself, and swapping the spout fixes it for very little. On a three-handle setup the diverter is a separate valve stem in the wall and gets rebuilt or replaced.

Low pressure in the shower
Clogged showerhead or supply issue.
Low shower pressure that affects only the shower, while other fixtures are fine, is usually a clogged showerhead or a partially closed supply shutoff. Mineral deposits from Front Range hard water pack into showerhead openings over time, reducing spray to a trickle.
You can test the showerhead theory yourself in ten minutes. Unscrew the head, hold it aside, and turn the shower on. If a strong stream comes out of the bare arm, the head was the problem and a soak in vinegar overnight or a new head solves it. If the arm dribbles too, the restriction is behind the wall and no amount of scrubbing the head will help.
If pressure is low at every fixture in the house, the problem is upstream. Older Littleton and Wheat Ridge homes still have galvanized supply that has scaled down internally to about the diameter of a pencil, and nothing on that line runs right until the pipe is replaced. The other suspect is a failing pressure-reducing valve at the service entrance, a far smaller repair worth ruling out first. Wes gauges pressure at a hose bib before suggesting anybody repipe anything, because those two look identical from inside the shower. If it is the supply, that becomes a pressure problem solved at the source.

Shower pan and drain leaks
Water under the floor before it shows below.
A shower pan that leaks allows water into the subfloor or ceiling below. These leaks develop from cracked grout, failed caulk at the curb, or a pan that was not properly waterproofed at installation. Wes investigates the source, addresses what is accessible without major demo, and advises on what the repair requires if the pan itself has failed. See our work.
The tell that separates a cheap repair from an expensive one is timing. A stain on the ceiling below that appears only while somebody is showering and dries out between uses is usually the drain connection, the shower arm, or the valve, all of which are reachable. A stain that stays damp all the time means water is standing in the pan structure itself, and that is a rebuild rather than a patch. Wes will plug the drain, fill the pan, and leave it sitting to find out which one you have before quoting anything, because guessing wrong in either direction costs somebody real money.
Grout gets blamed more than it deserves. Cracked grout does let water into the wall, but grout was never the waterproofing. The membrane behind it is. If that membrane is sound, failing grout is a cheap fix caught early. If it is not, regrouting hides the problem for a year while the framing keeps getting wet. Look at the inside corners and the curb, where caulk cracks first and where liner failures start.
Being a general contractor as well as a master plumber matters most on this kind of call. If the answer is that tile has to come off, Wes takes the tile off, does the plumbing, and puts the wall and finish back himself. You are not left holding a torn out shower while trying to find a tile guy who will take a small job, and there is nobody to blame anybody else when it is done. Larger scopes roll into a bathroom remodel.
Fix the valve, not the tile
Shower repairs done without unnecessary demo.
A dripping shower valve is fixed by replacing the cartridge inside the existing valve body, not by tearing out tile. Wes does the repair at the valve, tests that the drip is stopped and temperature is stable, and leaves the shower surround intact.
A steady drip costs more than the annoyance. It wastes a real amount of water over a month, and the constant trickle leaves a mineral track on the tile that eventually will not scrub off. Drips also tend to get worse rather than hold steady. The repair stays small right up until the valve body itself is damaged.

Questions about shower repair.
My shower drips when it is off. What is wrong?
Almost always a worn or scaled cartridge inside the valve body. The cartridge is what seals off flow when the handle is closed, and hard water builds up on the seats until they stop sealing. Replacing it stops the drip and does not involve touching tile, since the cartridge comes out through the trim opening.
Why do cartridges fail so fast around here?
Mineral content. Front Range water leaves calcium on everything it touches, including the sealing surfaces inside a cartridge, so seals cannot seat against a crusted face. The same fixture in a soft water town would go years longer. It is also why an old cartridge sometimes needs a puller to come out without cracking the valve body.
Why does the shower go scalding when someone flushes a toilet?
The pressure-balancing spool inside the valve has seized and is no longer compensating when cold pressure drops elsewhere in the house. On most valves that is part of the cartridge assembly, so replacing it restores the protection. If the valve is old enough that parts are gone, the valve body gets swapped instead.
My shower never gets hot enough. Is my water heater bad?
Check the cheap thing first. Most modern valves have a temperature limit stop under the handle, a small adjustable collar that caps how far toward hot the handle can travel. Set conservatively at the factory, it makes a perfectly good water heater feel undersized. Adjusting it takes minutes. If that is not it, then the heater gets looked at.
Why does water come out of the tub spout while the shower is running?
Worn diverter. On a tub and shower combination the diverter is usually built into the spout, and a new spout fixes it cheaply. On a three-handle setup it is a separate stem in the wall that gets rebuilt or replaced. Either way it is a small repair, and it is not the shower valve.
Can you fix a shower with low water pressure?
Yes, once the cause is known. Unscrew the showerhead and run the bare arm. Good flow means the head was clogged with scale. Weak flow means the restriction is upstream, which is either a partly closed shutoff, a failing pressure-reducing valve, or scaled galvanized supply. Those cost very different amounts, so nobody should guess.
How do I know if my shower pan is leaking or just the drain?
Watch the timing. A ceiling stain that appears while the shower runs and dries between uses points at the drain connection, shower arm or valve, all reachable. A spot that stays damp constantly means water is standing inside the pan structure. Wes plugs the drain and floods the pan to confirm before quoting either one.
Will regrouting stop a shower leak?
Usually not. Grout was never the waterproofing, the membrane behind the tile is. Cracked grout does let water into the wall, so fixing it early is worth doing, but if the membrane has failed, new grout just hides the problem while the framing keeps getting wet. The corners and the curb tell the real story.
