A stain on the ceiling directly under the shower
Escaped pan water follows the joist bay and drops at the first low point it finds, which is rarely under the drain itself.
Source of the water
Spearfish, SD
Our crew cleans up shower leaks and overflows, including moisture behind tile, beneath flooring, and inside nearby wall cavities.
Signs to look for
If you notice any of these problems, call us before water has more time to spread into nearby materials.
Escaped pan water follows the joist bay and drops at the first low point it finds, which is rarely under the drain itself.
Water that gets past the pan runs to the edge of the mortar bed and into the subfloor at the threshold.
Run a knuckle across the shower floor and listen for the tone to change from solid to empty.
Corners and the curb move slightly with the building, so rigid grout there cracks and reopens.
A shower curb is waterproofed over the top and down both faces, and its two ends are where that wrap is hardest to finish.
A shower curb is built to shed water back inward, and a door sweep or threshold seal keeps the rest in.
What happens
Our crew adjusts the work to which areas and materials are wet, the distance the water traveled, and what materials can be saved.
Before we look at the pan we rule out the toilet, the sink and the supply lines feeding the shower.
The drain is plugged and the pan is filled to just below the curb, then watched over a set period.
If the pan holds, water is directed at the curb, the corners, the door sweep and the valve trim in turn.
A traditional pan drains twice: once through the visible drain and once through weep holes at the base of the drain body.
A moisture meter reads the framing, subfloor, wall base and the ceiling underneath, and a thermal imaging camera shows the shape of the wet area.
We tap the shower floor and the lower walls and mark what has debonded. Hollow sounding areas typically come off in the repair anyway.

What to expect
Here is how we typically handle shower leak cleanup near Spearfish, SD.
On the call we ask one question first: does the water appear during a shower, or with nothing running.
Your callStop using it and use another bathroom if you have one. Every additional shower adds water to a structure that is already wet.
+5 minutesIf a ceiling is stained or bulging underneath, keep people out from under it and leave the area lit from a doorway.
+10 minutesA crew arrives, meters the wet area and sets up a flood test on the pan. While it sits, the walls, curb, door and valve trim are examined.
On arrivalWe show you where access is needed and why, and we select the least visible wall wherever the drying allows it.
First hours on siteAir movers deliver air into the wall cavity and under the flooring rather than across the room. An Professional dehumidifier holds the humidity down in a small closed space.
Day 1The three places that stay wet longest are the subfloor at the shower threshold, the framing behind the surround, and the ceiling below.
Day 2 to 4Understanding the cost
We walk you through the recommended cleanup plan and price before you approve the job. These examples show what may change the estimate.
| Common situation | What the estimate may include | Typical range |
|---|---|---|
| Shower leak caught early, drying the floor and wall base only | National estimate for diagnosis, testing, drying equipment and monitoring where nothing needs removal. | $500 to $1,500 |
| Wet wall cavity drying behind a tub or shower, one bathroom | National estimate for controlled openings, cavity drying and daily readings behind the surround. | $450 to $1,200 |
| Shower leak that reached the subfloor and the ceiling below | National estimate covering both rooms, including ceiling material removal, drying and cleaning. | $2,500 to $8,000 |
| Drying priced by affected area, clean water | National estimate used when the wet area is measured rather than priced as a room. | $3 to $7 per square foot |
| Tile and mortar bed removal, per square foot | National estimate for removal and disposal of tile with a mortar setting bed. Thinset over backer board sits at the lower end. | $3.00 to $8.00 |
| Shower pan flood test performed on its own | National estimate when the test is the only service requested. It is normally folded into a full diagnosis visit. | $150 to $400 |
| Shower pan or membrane rebuild by a tile contractor | National estimate for the rebuild trade, not our work plan. Included so you can see the whole picture. | $1,000 to $4,000 |
How long the shower has been leaking
A few weeks means wet framing and a drying work plan. A few years means a saturated mortar bed, a spongy subfloor and probably a rebuild.
Whether the tile and mortar bed have to come off
Drying can frequently be done through a small opening in an adjacent wall or from the ceiling below.
Which component actually failed
A door sweep or a caulk joint is a cheap fix once it is proven. A pan liner or a failed waterproofing membrane means the shower floor is rebuilt.
Access to the space under the bathroom
A basement or crawl space under the shower lets us dry the subfloor and joist bay from below, which is faster and cheaper.
How much of the room below is involved
A single stain is a small work plan. A ceiling that took water across two joist bays brings insulation, light fixtures and paint into the job.
Equipment days in a small closed space
Bathrooms dry well because they are small, but tile and mortar release moisture slowly.
Why timing matters
Water may keep moving into nearby materials even when the surface looks dry.
Unlike a burst pipe, this leak is switched on by the household. Two showers a day for a month is sixty separate wettings of the same framing.
Plywood that goes through repeated wet and dry cycles delaminates in layers.
A mortar bed sitting on a failed liner acts like a sponge that never gets to dry.
A wall cavity behind a shower is warm, dark and repeatedly rewetted, which is a favorable set of conditions.
Helpful service information
Begin with the short explanation. Open a card if you want a little more detail.
At the bottom sits the preslope, a sloped bed that sends water toward the drain.
A tile shower is a stack of layers, and knowing the stack explains every failure. At the bottom sits the preslope, a sloped bed that sends water toward the drain.
Grout and tile are the wear surface, not the seal, and water passes through both slowly by design.
The grout myth costs homeowners more money than any other idea in bathroom repair. Grout and tile are the wear surface, not the seal, and water passes through both slowly by design.
Mortar and tile hold moisture and release it gradually, so the room air can read normal while the setting bed is still saturated.
Drying a shower leak is different from drying a burst pipe, because the wet material is enclosed and slow.
Common questions
Timing is the first clue. If water appears during or shortly after a shower and nothing shows with the water off, the assembly is leaking rather than a pipe.
No, and this is the most common misunderstanding in shower repair. Grout is a filler between tiles and it is porous by design.
Sometimes the leak is at the curb, the door sweep, the valve trim or a corner joint, and those are repaired without touching the floor.
The drain is plugged, the pan is filled with water to just below the curb, and the level is marked and watched over a set period.
A traditional shower drain has small openings at its base that let water sitting on the pan liner escape into the drain.
Check whether it darkens after a shower and fades between them, which points at the shower rather than a pipe.
Three to five days is typical once the source is stopped and the equipment is in. Tile and mortar release moisture slowly, so the setting bed and the framing lag behind the room air.
