High humidity affects its structure over time. The porous nature of drywall lets moisture damage it easily. This can lead to costly repairs if you don’t fix it fast. What causes water damage in drywall? Plumbing leaks cause most drywall water damage. Hidden leaks form inside walls because of deteriorating pipes, burst plumbing, or shifting property structures. Water seeps from above into ceilings and walls because of roof problems like damaged shingles, faulty flashing, or clogged gutters. Bathrooms and kitchens don’t deal exceptionally well with poor ventilation that creates condensation on wall surfaces. The porous drywall absorbs moisture if there’s no proper airflow. Natural disasters, plumbing failures, and broken appliances like dishwashers, washing machines, and water heaters can also destroy drywall’s integrity. Signs your drywall has water damage You can save money on Toronto drywall installation and repairs by spotting water damage early. Look out for these warning signs: Why water-damaged drywall needs urgent repair Wet drywall loses its strength fast and becomes soft and weak. Affected walls start sagging, making your home unsafe. Quick water damage repairs stop these structural problems from getting worse. Wet drywall creates perfect conditions for mold that can start growing within 24-48 hours after getting wet. This can be dangerous to your family’s health by causing breathing problems, allergies, and other health issues. Small drywall repairs can become much more expensive if you wait too long. Water damage spreads to bigger areas and causes other problems. You need to act quickly. Water-damaged drywall that stays wet for several days needs major water damage repairs. This includes any insulation behind it.
