Regular maintenance of your subfloor can prevent long-term damage, offering a fresh, stable foundation for whatever flooring choice you make.

Introduction To Subfloor Maintenance

Clean subfloors are crucial for a healthy home. Like a solid foundation for a house, the subfloor supports everything above. Dirt, moisture, and grime can hide beneath flooring, causing damage over time. Regular cleaning and maintenance extend your floor’s life and ensure a safe living environment. This guide digs into the why and how of keeping subfloors spotless.
