What Subfloor Preparation Is Needed Before New Hardwood Floors Are Installed?

Before installing new hardwood floors, one of the most important steps is ensuring the subfloor is properly prepared. Without proper preparation, even the best hardwood can suffer from uneven wear, squeaking, or structural issues. For homeowners, property managers, or business owners, understanding what’s required helps avoid costly mistakes and ensures a long-lasting, beautiful floor. That’s why this question is so relevant for anyone planning a hardwood flooring project.

Subfloor Preparation Steps Before Hardwood Installation

The first step in subfloor preparation is ensuring the surface is clean, dry, and level. Dust, debris, or leftover adhesive from old flooring must be removed, as these can create uneven spots that affect stability. Moisture testing is also essential, since excess moisture in the subfloor can cause hardwood to warp or buckle. According to industry standards, moisture levels should typically not exceed 12% for wood subfloors. Professionals often use specialized meters to verify these levels before beginning installation.

In addition, any squeaks or loose sections of the subfloor need to be secured with screws or fasteners. High spots should be sanded down, while low spots may require leveling compounds. Some projects call for an underlayment to provide additional cushioning, noise reduction, or moisture protection. For concrete subfloors, proper sealing or vapor barriers are often required before hardwood can be installed. These steps ensure the hardwood floor remains stable, durable, and visually appealing for years to come.
