Irregular or damaged subsoil due to water damage. At some point, the floor in any room in your home may need to be repaired. Busy areas, such as lobbies, lobbies and living rooms, often suffer from heavy wear and tear that may require repairs over time. Areas that are exposed to moisture, such as kitchens and bathrooms, are also subject to many floor repairs due to potential water damage.
Saggy floors aren't necessarily dangerous. The problem is that weak joists and the softening of subfloors can cause sagging and worsen over time. So while they may not be dangerous now, they could be if you don't fix them. Typical problems include repairing a sunken floor, leveling a floor, fixing floors that squeak, or repairing water damage.
A significant amount of water can damage the subfloor, which means that, in addition to fixing the upper surface, there are also costs associated with repairing the subfloor. For example, very small damaged areas can generally be repaired quickly, while damage that takes up most of the floor may require replacement. At some point, it's cheaper to remove all of the affected floor and start over rather than trying to repair wood floors damaged by water. If the subfloor is damaged due to hurricanes, winds, or other weather-related disasters, you can probably use insurance to pay for the damage.
If your home was flooded or severely damaged by water or pests such as termites, you may want to replace the joists. For example, repairing a localized area with water damage on a hardwood floor will cost much less than water damage affecting all the floors on one floor of your house. Like floors that bend, deformation is a sign of improper installation or, more likely, of damage caused by standing water or simply by the presence of high humidity below the floor surface. The most popular types of floors are described below on an individual basis, and that section is followed by a graphic that shows the restoration options and the cost of repairing water damage from each one.
A rotten bathroom floor is usually caused by hidden water damage that slowly corrodes the floor and the subfloor below it. However, some surfaces in a humid area can be damaged by water and need to be replaced, increasing the total cost. Refinishing is a great way to restore old wood and some older stone floors with surface damage, such as scratches, crevices, and small hills or valleys. Damage to the subsoil is usually related to water in some way and can often occur as a result of leaks (think appliances or pipes), cracks in the floor or outside the house, and high humidity.
Before starting the project, turn off the bathroom's main water valve to prevent water from escaping while working on the floor.
