There are several potential reasons why dampness may have appeared in your house after it was renovated, even if the work was done recently. Some possible causes include:
Improperly sealed windows and doors: If the windows and doors in your house were not properly sealed during the renovation, moisture may be able to enter the building, leading to dampness.
Lack of adequate ventilation: Proper ventilation is important to help prevent moisture build-up inside a building. If your house lacks sufficient ventilation, dampness may occur.
Leaks in the roof or walls: If there are leaks in the roof or walls of your house, water may be entering the building and causing dampness.
Poor drainage around the foundation: If the ground around the foundation of your house is not properly graded to drain water away from the building, dampness may occur.
To fix these issues and prevent dampness from reappearing in the future, you may need to take a number of steps, such as sealing windows and doors, improving ventilation, repairing leaks, and improving drainage around the foundation. It may be helpful to consult with a professional contractor or building specialist Le Fong Building Services to determine the specific cause of the dampness and the most appropriate solution.
