Why Proper Hardwood Acclimation Could Save You Thousands in Future Floor Repairs

Picture this: you’ve just invested in beautiful hardwood floors for your home, only to discover gaps, warping, or buckling appearing within months of installation. Failing to properly acclimate wood flooring may cause excessive expansion, shrinkage, dimensional distortion or structural damage, including gapping where gaps appear between planks and warping and buckling where wood expands after installation, leading to warping, cupping, or even buckling. The culprit? Skipping or rushing the hardwood flooring acclimation process – a critical step that many homeowners don’t fully understand.

Understanding Hardwood Acclimation: More Than Just Waiting

Acclimation is “the process of adjusting (conditioning) the moisture content of wood flooring to the environment in which it is expected to perform,” says the National Wood Flooring Association. Wood is hygroscopic, meaning it expands and contracts with moisture, making this adjustment period essential for long-term performance.

Ideally, prior to installation, the flooring should be brought into equilibrium with the normal living conditions of the space it will inhabit. Simply stated: wood flooring has acclimated once it has reached equilibrium with the home kept at average normal living conditions.

The Science Behind Wood Movement

When wood flooring takes on too much moisture, individual boards will start to expand in width. This can cause boards to buckle or to appear cupped or swollen. Conversely, when wood loses moisture, it contracts and shrinks, creating unsightly gaps between planks.

In general, relative humidity in the building should be between 30-50 percent year-round for optimal wood flooring performance. We recommend keeping the home at 60-80° F and within 30-50% relative humidity for solid prefinished floors.

Proper Acclimation Steps for Success

The acclimation process requires specific steps to ensure effectiveness:

• Flooring will not acclimate properly if left in the plastic wrapping. Cross-stack the flooring, leaving room between each box for good airflow
• Permanent heating and/or air conditioning systems should be operating at least five days before you install your wood floors. This will allow the wood to acclimate to actual living conditions inside the building
• Using a moisture meter, get an initial baseline by measuring the moisture content (MC) of 20 boards per 1,000′ of flooring
• In most cases, the MC of the subfloor and flooring must be within 2% of each other to begin the installation

Geographic Considerations Matter

Your location significantly impacts acclimation requirements. For example, in New England where Vermont Plank Flooring is based, winters are cold and dry, while summers are warm and humid, prompting the potential for sizable seasonal expansion and contraction. In the winter, in a home heated by dry wood heat, the acclimation period will likely be fairly lengthy, while in the summer, with no air conditioning in the structure to control for temperature and humidity (as with many northern homes), acclimation may be almost instantaneous since the moisture content of the hardwood flooring and subfloor may already be within 2 percent of one another.

Engineered Hardwood Considerations

Many homeowners mistakenly believe engineered hardwood doesn’t require acclimation. Though it is true that engineered products do not swell and shrink with environmental fluctuations as much as solid hardwoods, they do still have the capacity to expand and contract. As such, they also should be acclimated to the surrounding environment, as judged by comparative moisture reading between the flooring and the sub-floor, even if the subfloor is concrete.

The Cost of Cutting Corners

Rushing the process could lead to gaps, cupping, or warping—problems that will cost far more time and money to fix later. Boards can push or pull against the fasteners in the floor. Eventually causing squeaks or loose boards.

Long-Term Success Through Proper Planning

The rule to remember is this: wood floors do best when there is consistent temperature and humidity. After acclimating your floors, maintain a consistent home environment to help prevent movement, squeaks, and stress on the floor.

Proper hardwood acclimation isn’t just a recommendation – it’s an investment in your floor’s longevity. By taking the time to properly condition your hardwood before installation, you’re protecting both your investment and your home’s beauty for years to come. By allowing your floors to adjust to their new environment, you’re ensuring they look beautiful and function well for years to come. With proper acclimation, your hardwood floors will not only enhance your home’s aesthetic but also stand the test of time.
