What is Subfloor Preparation?

Subfloor preparation is the process of preparing the subfloor for the installation of new flooring. This includes removing any existing flooring, cleaning the subfloor, and addressing any issues with the subfloor, such as cracks or unevenness. Proper subfloor preparation ensures that your new flooring will be installed on a level, clean, and stable surface, which will help it last longer and look better.

The Consequences of Neglecting Subfloor Preparation

Neglecting subfloor preparation can lead to a range of problems that can be costly and time-consuming to fix. Some of the consequences of neglecting subfloor preparation include:

  • Uneven Floors: An uneven subfloor can cause your new flooring to be uneven as well. This can cause tripping hazards and make the flooring look unattractive. Additionally, an uneven subfloor can cause the flooring to wear unevenly, which can shorten its lifespan.
  • Moisture Damage: If your subfloor has moisture issues, such as leaks or high humidity levels, it can cause your new flooring to warp or buckle. Moisture can also cause mold and mildew to grow, which can be hazardous to your health.
  • Noise: A subfloor that is not properly prepared can lead to squeaky or noisy floors. This can be a nuisance and can also indicate that there is an underlying issue with the subfloor.

The Importance of Proper Subfloor Preparation

Proper subfloor preparation is essential for a successful flooring installation. Here are some reasons why:

  • Ensures a Level Surface: If the subfloor is not level, it can cause the new flooring to be uneven, which can lead to tripping hazards and an unattractive appearance. Proper subfloor preparation ensures that the subfloor is level and ready for installation.
  • Extends the Life of Your Flooring: A properly prepared subfloor provides a stable base for your new flooring. This stability can help your flooring last longer, saving you money in the long run.
  • Prevents Moisture Damage: Moisture damage can cause your flooring to warp or buckle, and can also lead to mold and mildew growth. Proper subfloor preparation can help prevent moisture damage and ensure that your flooring stays in good condition.
  • Improves Indoor Air Quality: If there is mold or mildew growth under your flooring, it can negatively impact your indoor air quality and your health. Proper subfloor preparation can help prevent mold and mildew growth and improve your indoor air quality.

Steps for Proper Subfloor Preparation

Proper subfloor preparation requires several steps. Here are the basic steps for subfloor preparation:


  1. Remove Existing Flooring: If there is existing flooring on the subfloor, it must be removed before preparing the subfloor. This includes any adhesive or residue left behind by the previous flooring.
  2. Clean the Subfloor: After removing the existing flooring, the subfloor should be thoroughly cleaned. Any debris, dust, or dirt should be removed, and the subfloor should be swept and vacuumed.
  3. Inspect the Subfloor: The subfloor should be inspected for any damage, such as cracks or holes. Any damage should be repaired before proceeding with the installation.
  4. Level the Subfloor: If the subfloor is not level, it should be leveled using self-leveling compound or plywood.
  5. Address Moisture Issues: If there are any moisture issues, such as leaks or high humidity levels, they should be addressed before proceeding with subfloor preparation. Moisture barriers or sealers can be used to prevent moisture from seeping through the subfloor.
  6. Allow the Subfloor to Settle: After leveling and repairing any damage, it is important to allow the subfloor to settle for at least 24-48 hours before proceeding with installation.


Proper subfloor preparation is essential for a successful flooring installation. Neglecting subfloor preparation can lead to a range of problems, including uneven floors, moisture damage, and noise.
