A floor is only good as the subfloor underneath it. Subfloors made of wooden materials such as oriental stand board and untreated plywood can be damaged by external factors such as moisture. In such an instance, the subfloor needs to be removed and replaced. People can replace subfloors by DIY, but it’s better to call a floor service company.
According to the narrator in the video, it’s essential to establish what damaged the subfloor, where it came from, and inspect the wood joists under the subfloor for damage.
A flooring service repair company can install a vapor barrier or a crawlspace fan to prevent future subfloor damage. It’s also vital to redirect roof water to prevent it from dripping next to the foundation.
Subfloor repair can be done by removing the plywood on the affected section or removing all the plywood. Removing plywood in the affected area is problematic because it’s hard to match the new subfloor with the old one. This means buying new plywood boards and hiring a floor service company to install them on the whole space is the best option.
