Is your paint peeling, blistering or coming off in certain places? Is your wallpaper peeling?
You may have a problem of rising dampness that rises from the ground into your walls through capillary action. Excessive humidity can also result from water infiltration due to a defect in your roof, a crack... Or from water penetrating the side walls from the ground and infiltrating the underground parts of the house.
In this case, you may see signs of moisture on your walls, such as damaged siding or peeling wallpaper. Water that tends to bead on surfaces, or a floor that floods frequently, leave no room for doubt.. But the problem may not be visible and may be felt as a difficulty to heat the room with a cold sensation linked to the air loaded with moisture.
All of these signs should be taken seriously as soon as possible to avoid more alarming signs of moisture problems. Indeed, certain effects of humidity can lead to real health risks in your home.
