Building deterioration refers to the gradual decline in the condition of a structure due to various factors such as age, weather, and lack of maintenance. Over time, materials like wood, concrete, and metal can weaken, leading to issues like cracks, rust, and mold. This process can be accelerated by environmental conditions, such as moisture, temperature fluctuations, and exposure to pollutants. Preventing building deterioration involves regular inspections and maintenance to address minor issues before they become major problems. Proper care can include repairing leaks, cleaning gutters, and applying protective coatings. By taking these steps, property owners can extend the lifespan of their buildings and ensure safety for occupants.
