The Causes of Dampness in Coastal Homes:

There are a numerous factors that can cause dampness in coastal homes, including:

High humidity levels: 

The high humidity levels in coastal areas can cause moisture to build up in the home. This is because the air is already saturated with moisture, so any additional moisture that enters the home will have nowhere to go but to condense on surfaces.


Rain can also cause dampness in coastal homes, especially if the home is not properly sealed. If there are any cracks or gaps in the walls or foundation, rain can easily seep in and cause moisture to build up.


Wind can also drive moisture into the home, especially if there are cracks or gaps in the walls or foundation. The wind can also whip up moisture from the ground and carry it into the home.

Poor drainage:

If the drainage around the home is poor, this can also contribute to dampness. If water is not able to drain away from the foundation, it can seep into the home and cause moisture to build up.

Expert Tips for Preventing Dampness in coastal homes:

Seal any cracks or gaps in the walls, foundation, or roof. This is one of the most important things you can do to prevent dampness. Cracks and gaps can allow water to seep into the home, and they can also be a breeding ground for mold and mildew.

Keep the gutters and downspouts clean and free of debris. Clogged gutters and downspouts can cause water to back up and overflow, which can lead to dampness.

Ventilate the home regularly. This will help to remove moisture from the air and prevent it from condensing on surfaces.

Use moisture-absorbing materials in areas where moisture is a problem. 

Heat the home to at least 68 degrees Fahrenheit during the winter. This will help to prevent moisture from condensing on surfaces.
