Shower Repair in Denver, CO
A shower that leaks behind the wall, runs cold halfway through, or drains slowly has a cause we can find. We trace it to the valve, the cartridge, or the drain, and fix what actually failed.
Service overview
Valve, cartridge, or drain: find the fault
Shower repair in Denver is the diagnosis and fix of a shower that leaks, loses pressure, swings temperature, or drains slowly. Most shower faults sit in the mixing valve behind the wall: a worn cartridge that will not shut off, a pressure-balancing spool that has seized, or a valve body that has started to weep. A shower that runs hot then cold is often a cartridge or a pressure problem, not a water heater fault. A drain that is slow usually means hair and soap have built up in the trap or the line beyond it. In Denver's older homes, the valve may be an original two-handle setup with washers that have hardened, and the tile around it may be the reason a repair needs care rather than force.
! Common warning signs
A shower that drips or will not shut off
A shower that keeps running after the handle is off has a cartridge or washer in the mixing valve that no longer seals. It wastes water day and night and will not fix itself.
Temperature swings mid-shower
When a shower's temperature swings as another fixture opens, a seized pressure-balancing spool or a failing cartridge is the usual cause — the valve, not the heater.
Slow drainage or water at the base
A slow drain points to buildup in the trap or the line. Water at the base of the shower points to a failed seal or a drain connection that needs attention.
Scope of work
What a shower repair visit covers
A shower repair starts at the valve and the head: we trace low pressure, leaks and temperature swings to the cartridge, the supply or the drain before any part is changed. Here is what the visit covers.
-
01
Valve and cartridge diagnosis
We identify the valve type, test the cartridge and pressure-balancing spool, and check the valve body for leaks behind the wall.
-
02
Temperature and pressure testing
We run the shower with other fixtures open to see whether the temperature holds, which tells us whether the fault is the valve or the supply.
-
03
Drain and trap check
A slow drain is traced through the trap and the line beyond it, so a blockage is cleared at its source rather than pushed further down.
-
04
Seal and grout inspection
The shower base, the door seals, and the grout lines are checked for the gaps that let water reach the wall and floor behind the shower.
Repair or replace: how the call is made
A shower with a worn cartridge or a blocked trap is worth repairing, and most are. A shower with a corroded valve body behind the wall, or tile and a shower pan that have failed together, is a different conversation, and we lay out the replacement option when the diagnosis points that way.
Call (720) 599-7253Tools and methods we use
Cartridge puller
It draws a seized shower cartridge out cleanly, leaving the valve body unmarked and the valve repairable.
Pressure testing
Runs the shower with other fixtures open to test whether the valve holds temperature under real household use.
Drain auger
Clears the trap and the line beyond it so a slow shower drain is fixed at the blockage rather than pushed further down.
Leak tracing
Finds whether water comes from the valve, the shower arm, the drain, or the seals, since each has a different fix.
Local execution
Shower repair in Denver runs into the city's older bathrooms. In Capitol Hill and Congress Park, pre-war homes often still have two-handle shower valves with washers that have hardened over decades, and the tile around them is original, so access has to be planned rather than forced. In Park Hill and Baker, 1920s and 1930s bungalows mix original valves with later replacements, and identifying the cartridge takes care. Denver Water reports hardness of about 89–105 mg/L (5.2–6.1 gpg), and that mineral load clogs showerheads and stiffens cartridges across the city.

Shower leaking or running cold? Call to book a visit
What to do while you wait
A dripping shower wastes water, and a leak behind the wall can damage the framing, so neither should wait long. Call (720) 599-7253, describe the shower and the fault, and we will confirm availability when you call. If water is leaking through a ceiling below, shut off the shower and avoid using it until we have seen it.
What to expect from your shower repair
Call and describe the fault
Call (720) 599-7253 and tell us what the shower does: drips, swings temperature, drains slowly, or leaks. We set a time that fits your day.
On-site diagnosis
We identify the valve, test the cartridge and pressure balance, and check the drain and seals so the fault is found before any part is replaced.
Repair and testing
The worn part is replaced or the drain is cleared, and the shower is run with other fixtures open to confirm the temperature holds and the drain runs clear.
What shapes the cost of shower repair in Denver
No price is published for a shower repair: the scope turns on the valve type and whether the fault is in the valve, the drain or the seals. We talk through what the repair involves before any work starts, and agree the scope with you before any work starts.
Valve type and part
Which valve it is sets much of the scope. A single-lever cartridge valve and a two-handle washer valve fail differently, use different parts, and are different repairs.
Access behind the wall
A valve with an access panel is simpler to service than one buried behind original tile, and access shapes the visit.
Drain or seal work
A blocked trap is a different job from a failed shower pan seal, and the cause decides the scope of the repair.

Frequently asked questions
Why does my shower keep dripping after I turn it off?
A shower head that drips usually means the cartridge or washer in the mixing valve no longer seals. The valve is identified first, so the replacement part matches and the drip stops.
Why does my shower go hot and cold?
A shower that runs cold when another fixture opens usually points to the valve: a seized pressure-balancing spool or a failing cartridge that cannot hold temperature. The water heater is rarely the cause.
Why is my shower draining slowly?
Hair and soap buildup in the trap or the line beyond it is the usual cause. We trace the blockage through the trap and the line so it is cleared at its source.
Should I repair or replace my shower valve?
A valve with a worn cartridge is worth repairing. A corroded valve body behind the wall, or tile and a shower pan that have failed together, is a different conversation. We lay out both options when the diagnosis points that way.
