Hardwood Subfloor Preparation Guide
Preparing for Hardwood Installation
The subfloor is the foundation beneath every hardwood installation. Even premium flooring can develop movement, squeaks, uneven areas, or installation problems when the surface underneath it has not been properly evaluated and prepared.
Professional subfloor preparation creates a clean, flat, dry, and structurally sound foundation for the hardwood above it.
Evaluating the Subfloor
Before installation begins, the existing subfloor should be inspected for structural stability, moisture, flatness, damaged areas, contaminants, and previous flooring materials.
Wood and concrete subfloors require different preparation methods, making it important to understand the surface before selecting an installation system.
Preparing the Surface
Subfloor preparation may include:
Removing existing flooring
Removing staples and fasteners
Cleaning adhesive residue
Correcting damaged areas
Securing loose subfloor panels
Flattening uneven surfaces
Testing moisture conditions
Preparing transitions and elevations
Correcting these conditions before hardwood installation helps prevent problems from being transferred into the finished floor.
Correcting Uneven Areas
Hardwood flooring performs best over a sufficiently flat surface. High areas, low areas, seams, damaged panels, or irregular concrete can interfere with proper board placement and create movement after installation.
The appropriate correction depends on the subfloor material, severity of the problem, and hardwood installation method being used.
Managing Moisture
Moisture evaluation is one of the most important parts of subfloor preparation. Excessive moisture can contribute to expansion, cupping, buckling, adhesive failure, and other hardwood flooring problems.
Testing both the flooring and installation environment helps determine whether conditions are appropriate before hardwood is installed.
