The short answer
Moisture Detection
Before any water is removed, the pros find where it is hiding. Tile and grout can hide moisture that is not visible on the surface. Moisture meters and thermal imaging tools help locate saturated areas without pulling up every tile.
This step matters because water can travel under the tile along the subfloor, affecting areas far from the original leak. Knowing the full extent of the water helps the pros decide whether targeted drying will work or if some tile needs to be lifted.
- Moisture meters read dampness in grout and subfloor
- Thermal imaging shows cool, wet spots behind tile
- Probing tools test for hollow sounds under tiles
- Inspection covers the whole room, not just the visible puddle
- Results guide the drying plan and any needed removal
Water Extraction Methods
If water is pooled on the surface, extraction starts with a wet vacuum or a portable extraction unit. These tools pull standing water off the tile quickly. But water under the tile is different, it sits in the thin gap between the tile and the subfloor.
For that trapped water, the pros may use specialized mats or vacuum attachments that create suction through the grout lines. In some cases, small holes are drilled into the grout to let the water escape so it can be extracted.
Drying Under the Tile
Extraction removes the liquid water, but the subfloor and the adhesive under the tile may stay damp. Drying equipment, such as air movers and dehumidifiers, is placed in the room to pull moisture out of the porous materials. This process can take several days.
The pros monitor moisture levels daily to see if the drying is working. If the moisture does not drop, that is a sign that water is still trapped or that the subfloor is damaged. In those cases, removing the tile may be the only way to dry the area properly.
- Air movers circulate dry air across the floor
- Dehumidifiers pull moisture from the air
- Moisture checks track progress each day
- Drying time depends on the amount of water and materials
- Grout lines may be opened to speed air flow
When Tile Must Be Removed
If water has been under the tile for a long time, or if the subfloor is soft or warped, the tile may need to come up. The pros carefully lift the tiles, often saving them for reuse. The subfloor is then dried or replaced, and the tile can be reinstalled.
Removal is a last resort because it is more involved and costly. But leaving wet subfloor can lead to mold and structural issues. The pros will only remove what is necessary and will work to keep the area tidy.
Preventing Future Water Under Tile
Once the water is out and the floor is dry, the pros may reseal the grout to reduce water absorption. Sealing does not make tile waterproof, but it helps resist moisture. Fixing the source of the water, like a leaky pipe or a poor seal around a tub, is also key.
Keeping an eye on indoor humidity and checking for leaks after heavy rain can help you catch problems early. Regular checks of caulking and grout can prevent water from finding its way under your tile in the first place.

How long does it take to dry water under tile?
Drying can take anywhere from two to five days, depending on the amount of water, the type of subfloor, and the drying equipment used. The pros check moisture levels daily and will tell you when the floor is fully dry. Acting quickly helps shorten the process.
Can water under tile cause mold?
Yes, trapped moisture under tile can lead to mold growth on the subfloor and adhesive. Mold can spread and cause health issues. If you see or smell mold, or if you feel unwell, see a doctor. The pros can assess the situation and recommend the right steps.
Will my tile need to be replaced?
Not always. If the tile and grout are in good shape and the subfloor dries out completely, the tile can often stay. If the subfloor is damaged or the tile is loose, some tiles may need to be lifted and reinstalled. The pros will explain what is needed.
