The short answer
Signs of Trapped Water
Water under linoleum is not always visible, but there are clues. Look for raised areas or bubbles in the flooring, which often mean moisture has lifted the adhesive. Discoloration or dark spots can also signal trapped water, especially if the floor feels soft or flexes when you step on it.
Another sign is a musty odor, which may develop within a day or two. If the linoleum was laid over a wood subfloor, trapped water can cause the wood to swell and warp. Pay attention to any changes in texture or sound when you walk across the room.
- Bubbles or wrinkles in the linoleum surface
- Dark or stained areas that appear without a known spill
- A spongy or soft feeling underfoot
- Musty or earthy smell coming from the floor
- Peeling or lifting at the edges of the linoleum
- Visible moisture seeping out from seams or corners
How Water Gets Under Linoleum
Water can seep under linoleum through seams, edges, or small tears. A leaky appliance, such as a dishwasher or refrigerator, can send water across the floor and under the material. Flooding from a burst pipe or heavy rain can also find its way beneath the surface.
Sometimes the source is not obvious. High humidity in the home can cause condensation to form under the linoleum, especially in basements or bathrooms. Even a small amount of water can get trapped if the adhesive is weak or the floor is damaged.
- Leaks from nearby appliances or plumbing
- Flooding from a broken pipe or severe weather
- Spills that are not cleaned up quickly
- Condensation from high indoor humidity
- Cracks or gaps in the linoleum surface
- Poorly sealed edges or seams
Why You Should Act Fast
Trapped water can lead to mold growth within 24 to 48 hours, which may spread to the subfloor and even the walls. Mold can cause health issues, especially for people with allergies or asthma. The longer the water sits, the more damage it can do to the flooring and the structure underneath.
Water can also weaken the adhesive that holds the linoleum in place, causing it to loosen or peel. In some cases, the subfloor may rot or warp, requiring more extensive repairs. Acting quickly can reduce the risk of long-term problems and make the cleanup easier.
- Mold can grow quickly in moist conditions
- Wood subfloors can rot or warp
- Adhesive may break down, causing the linoleum to lift
- Odors can become noticeable and hard to remove
- Repairs can become more costly if the damage spreads
What You Can Do Now
Start by removing any furniture or items from the affected area to allow air to circulate. If you can see the source of the water, such as a leaky pipe, turn off the water supply to your home if it is safe to do so. Use towels or a wet vacuum to soak up as much surface water as possible.
If the linoleum is bubbling, you might be able to release the water by making a small slit with a utility knife, then press the floor down to let the water out. Be careful not to damage the linoleum further. After removing the water, use fans or a dehumidifier to dry the area thoroughly.
Keep the room well-ventilated and monitor the floor for any signs of remaining moisture. If the water has been trapped for more than a day or the subfloor feels soft, you may need to remove the linoleum to fully dry the area. In that case, it is wise to have a professional assess the situation.
