Moisture Readings and Floor Cracking

What is an Acceptable Moisture Reading in a Hardwood Floor?

Moisture intrusion into a hardwood floor can cause significant damage, including buckling, cupping, and cracking. It is crucial to maintain proper moisture levels to ensure the longevity and integrity of your flooring.

Generally, an acceptable moisture reading for a hardwood floor will vary based on the species and environmental conditions.

Acceptable Moisture Content Range

• For red oak, white oak, and maple floors: 6-9%
• For hickory and ash floors: 7-10%
• For Brazilian hardwoods: 10-12%

Consequences of Improper Moisture Levels

• Moisture levels below the acceptable range can cause gaps, shrinkage, and splitting.
• Moisture levels above the acceptable range can lead to swelling, buckling, and mold growth.

Measuring Moisture Content

The moisture content of a hardwood floor can be measured using a moisture meter. These devices measure the electrical resistance between two pins inserted into the floor. The readings are then converted into a percentage of moisture content.

Preventing Moisture Damage

Maintaining proper moisture levels in a hardwood floor is essential for preventing damage. Steps can be taken to control moisture, including:

• Installing a vapor barrier under the floor
• Using a dehumidifier during humid seasons
• Addressing any water leaks or sources of moisture intrusion

By understanding and maintaining acceptable moisture readings, homeowners can protect their hardwood floors from damage and ensure their longevity and beauty.
