Acclimation is the process of allowing your hardwood to adjust to the environment of your home, and it's absolutely essential for preventing problems like warping, cupping, or gapping. Acclimation time takes usually three to seven days depending on factors like the type of wood, the board width, the climate, and the conditions inside your house.
Key Takeaways:
- Type of flooring, climate conditions, and board width influence acclimation time.
- Use a moisture meter to be sure your wood is ready.
- Skipping acclimation can lead to cupping, warping, buckling, and gapping.

What is Hardwood Floor Acclimation?
Wood is a natural material that reacts to its environment. It naturally absorbs and releases moisture depending on the surrounding temperature and humidity levels.
Acclimation is the process of allowing your hardwood flooring to adjust its moisture content to match the specific conditions of the room where it will be installed.
Why Does This Matter?
If hardwood flooring is installed before it's fully acclimated, problems can arise.
If the wood is too moist when installed, it will start drying out in your home's environment, causing it to shrink and potentially create gaps between boards.
On the other hand, if the wood is too dry when installed, it could absorb moisture and expand, leading to cupping, buckling, or other damage.
Acclimation helps ensure that your hardwood floor is dimensionally stable once installed, reducing the likelihood of costly and unsightly problems down the road.
How Long Do Hardwood Floors Need to Acclimate?
Unfortunately, there's no one-size-fits-all answer to how long hardwood floors need to acclimate. The ideal timeframe depends on several factors, but here's the general rule of thumb:
- Minimum: Most manufacturers recommend a minimum of 3 days for acclimation, but 5-7 days is often a safer bet.
Factors that Influence Acclimation Time
- Type of Hardwood Flooring: Solid hardwood generally takes longer to acclimate than engineered hardwood, which is designed to be more dimensionally stable.
- Board Width: Wider planks typically need more time to acclimate compared to narrower ones.
- Climate Differences: If the hardwood flooring is coming from a location with a vastly different climate than your home, it will need more time to adjust.
- Interior Conditions: The temperature and humidity levels within your home will affect how quickly the wood reaches equilibrium.
The acclimation guidelines above are just a starting point. The best way to ensure your hardwood is ready for installation is to use a moisture meter to check its moisture content compared to the subfloor and your home environment.
How to Properly Acclimate Hardwood Floors
Acclimating your hardwood floor isn't complicated, but it does require a little planning and patience. Follow these steps for best results:
1. Bring the Flooring Inside
Once your hardwood flooring is delivered, move it into the room where it will be installed. Avoid storing it in garages, basements, or other spaces with uncontrolled temperature and humidity.
2. Open Boxes and Distribute Boards
Carefully open the boxes and spread the boards out to allow for maximum airflow around them. Stacking the boards with spacers between layers aids in airflow.
3. Maintain Consistent Conditions
Ideally, the room where your hardwood is acclimating should have a temperature between 60 and 80 degrees Fahrenheit with a relative humidity of around 30-50%. Use your HVAC system to maintain these conditions.
4. Use a Moisture Meter
Don't rely on guesswork! Invest in a wood moisture meter. Take regular readings of the flooring and compare it to the moisture content of the subfloor. General guidelines are that the wood and subfloor should be within 2-4% of each other, but it's best to follow your specific flooring manufacturer's recommendations.
Continue maintaining consistent temperature and humidity levels in your home even after the flooring is installed. This will help minimize seasonal movement of your hardwood.
The Consequences of Not Acclimating Hardwood Floors
Skipping acclimation might seem like a way to save time, but it's a gamble that can end up costing you dearly in both money and frustration. Here are some of the most common problems you might face if you install hardwood flooring before it's properly acclimated:
Cupping and Crowning
Cupping occurs when the edges of the boards rise above the center, creating a concave shape. Crowning is the opposite, with the center of the board bulging upwards. These warpings are caused by uneven moisture absorption.
Buckling
In extreme cases, if the wood takes on too much moisture, the expanding boards can put immense pressure on each other, causing the floor to buckle upwards. This is a severe problem requiring major repairs.
Gapping
If the wood is too dry when installed, it will eventually take on moisture from the environment and expand. Conversely, overly moist wood that dries out will shrink. Both scenarios can lead to noticeable gaps between the boards.
Finish Damage and Structural Issues
The movement of boards that haven't acclimated can damage the finish on your floors and in severe cases, even compromise the stability of the floor's structure.
The Cost of Neglecting Acclimation
The problems listed above don't just diminish the beauty of your floor – they can lead to costly repairs or even necessitate replacing the entire installation. Taking the time to acclimate your flooring correctly is a small investment that protects the longevity and appearance of your hardwood floors.
