The short answer
The First Step Is Removing Water
Start by stopping the water source. Remove any standing water from the tile surface using a wet vacuum or mop. Tile itself is waterproof, but water can seep through cracks or porous grout lines. This water can pool underneath and soak the subfloor, creating a bigger problem that is not visible from above.
Act quickly to prevent the water from spreading. Leaving water under the floor can warp the subfloor and cause mold growth within 24 to 48 hours. If you have a large amount of water, or if it has been sitting for a while, contacting local water damage pros for extraction is a wise move to protect your home's structure.
Drying the Tile and Subfloor Completely
After extraction, the critical work is drying. Surface drying is not enough. Professionals use specialized air movers and dehumidifiers to pull moisture from the grout and, more importantly, from the subfloor and floor joists below. They often need to pull up a few tiles or use probes to check the moisture content deep within the flooring layers.
This drying process can take several days. The pros monitor the moisture levels until they return to a dry standard. Rushing this step can trap moisture, leading to mold or wood rot. Proper drying preserves the structural integrity of your floor and prevents future odors and damage.
- Use air movers to circulate air across the tile surface.
- Place dehumidifiers to remove moisture from the room's air.
- Employ moisture meters to check tile, grout, and subfloor.
- Lift corner tiles or use inspection holes to assess underlayment.
- Direct drying equipment into subfloor cavities if accessible.
- Continue monitoring until all materials are thoroughly dry.
Assessing and Repairing the Subfloor
The subfloor, often made of plywood or oriented strand board, is vulnerable to water. If it has been soaked, it can swell, warp, or rot. A soft, spongy feeling when walking on the tiles is a sign of subfloor damage. In many cases, the subfloor must be dried in place, but severe damage requires cutting out and replacing the affected sections.
This repair is complex. It involves removing tiles, cutting out the bad subfloor, and installing new material before re-setting tiles. It requires skill to match the height and ensure a level surface. Attempting this yourself can lead to an uneven floor or broken tiles.
Cleaning and Restoring Grout and Tile
Once everything is dry, cleaning is next. Water can stain grout and leave mineral deposits or promote mildew growth on it. A thorough cleaning with appropriate, pH-neutral cleaners can often restore the look. For stubborn stains or mildew, a professional cleaning may be necessary to avoid damaging the grout or tile finish.
Inspect the grout for cracks or missing sections. Damaged grout is an entry point for future water leaks. Regrouting those areas seals the floor again. If tiles are loose, they can be re-adhered. If tiles are cracked or stained beyond cleaning, individual tile replacement might be needed.
When Professional Help Is Essential
For any significant water event, calling the pros is recommended. They have the tools to find hidden moisture you cannot see. They follow industry standards for drying to prevent secondary damage. If you suspect mold, a separate mold assessment by a qualified professional is advised before any restoration begins.
The cost for this service depends on the extent of water, size of the area, and materials involved. It often ranges from several hundred to a few thousand dollars. Policies vary, and your insurer decides what is covered. Discuss the situation with your insurance company to understand your policy details.

Can water-damaged tile grout be saved?
Often, yes. Once completely dry, grout can be deep-cleaned to remove stains and mildew. If the grout is cracked or crumbling, it must be scraped out and replaced. Sealing the new grout helps protect it from future moisture.
How long does it take to dry under tile floors?
Drying a wet subfloor under tiles typically takes two to five days with professional equipment. The time depends on the amount of water, the subfloor material, and indoor humidity. Rushing this step risks mold and rot.
Will my homeowner's insurance cover tile floor restoration?
Coverage depends on the cause of the water damage. Sudden, accidental events like a burst pipe are often covered, while slow leaks may not be. Policies vary, and your insurer decides what is covered. You should file a claim and provide documentation.
