Wood floor acclimatisation is the process of allowing wooden flooring planks to adjust to the temperature and humidity levels of the space where they’ll be installed. This step ensures that the wood reaches a moisture balance with its new environment before being permanently fixed in place.
Because wood is a natural, hygroscopic material, it constantly reacts to changes in moisture and climate. If installed without proper acclimatisation, wooden boards may expand or contract after installation — leading to issues like gapping, warping, or buckling that compromise both appearance and durability.
- Meaning: Letting wood adapt to indoor conditions before installation
- Purpose: Prevent long-term damage caused by moisture shifts
- Duration: Typically between 5–14 days depending on environment
Whether you are installing solid hardwood or engineered wood flooring, understanding and respecting this process helps ensure a smooth, lasting finish. For more on how moisture affects wood floors and how to repair related damage, check out our guide to hardwood floor repair.
Is Acclimatisation Always Necessary?
The short answer is: it depends. With modern manufacturing techniques, many wood flooring products today are pre-dried and engineered for stability, which means they may not require extensive acclimatisation. However, that doesn’t mean you should skip the step entirely — especially if your home has unusual humidity levels or if you are installing solid hardwood.
High-quality pre-finished solid wood and engineered wood flooring often come with controlled moisture content, making them more resistant to environmental changes. In these cases, a shorter acclimatisation period of 3–5 days can still be beneficial to ensure full stability in the installation space.
- Modern Pre-Dried Wood: Ready for quick installation with minimal risk
- Traditional Solid Planks: Benefit from a full 7–14 day acclimatisation
- Reclaimed or Unsealed Wood: Requires extended adjustment due to unpredictable moisture history
If you are unsure whether your flooring needs acclimatisation, it is always best to consult the manufacturer’s guidelines or speak with a professional installer.

What Happens If You Skip Acclimatisation?
Skipping the acclimatisation process may seem like a time-saver, but it can lead to serious and often expensive problems down the line. Wood flooring that hasn’t adjusted to its environment is at risk of expanding, contracting, warping, or even buckling after installation — all of which can ruin the look and integrity of your floor.
If wood planks are too dry when installed in a more humid space, they will absorb moisture from the air and expand. This expansion can cause the boards to push against each other, resulting in cupping, bowing, or even lifting off the subfloor. On the flip side, if the wood is too moist and installed in a dry environment, it will shrink over time — leaving visible gaps between the boards.
- Expansion Risk: Moisture absorption leads to swelling and pressure damage
- Gapping: Boards shrink in dry conditions, creating unsightly cracks
- Warping: Uneven moisture causes uneven board shape and surface irregularities
These issues not only affect the aesthetics of your floor but also compromise its structural performance and longevity. In many cases, correcting these problems requires partial or full replacement — making proper acclimatisation a much more cost-effective choice from the start.
How to Properly Acclimate Your Wood Flooring
Proper acclimatisation is simple, but it requires attention to detail and a bit of patience. The goal is to allow your wood flooring to reach a moisture equilibrium with the environment where it will be installed — ensuring long-term stability and performance.
The process begins the moment your flooring arrives at your property. Instead of rushing into installation, follow these key steps to ensure optimal results:
- Storage: Keep the planks in the room where they’ll be installed — not in a garage or storage unit.
- Environment: Maintain normal living conditions (heating or cooling should be running as usual).
- Time: Allow between 5–14 days depending on initial moisture content and indoor climate.
It is also important to store the flooring correctly during this time. Leave the planks in their original packaging and stack them off the ground on spacers to allow for proper air circulation. Avoid placing them directly against walls or near heat sources that could cause uneven drying.
For best results, use a wood moisture meter to check the boards’ moisture levels before and during acclimatisation.

Frequently Asked Questions
How long should wood flooring acclimate before installation?
Most wood floors need 5–14 days of acclimatisation, depending on the initial moisture content and indoor conditions. Always check with a moisture meter for accuracy.
Can you skip acclimatisation if the wood is pre-dried?
Some modern pre-finished or engineered wood products are more stable and may not require full acclimatisation. However, it is still wise to let them adjust for 3–5 days to ensure optimal performance.
What happens if wood flooring is installed without acclimatisation?
You risk future issues like gapping, warping, cupping, or buckling due to moisture imbalance. These problems can lead to costly repairs or replacement down the line.
Do engineered wood floors need to be acclimatised?
Yes — although engineered wood is more stable than solid hardwood, it still benefits from a short acclimatisation period (usually 3–7 days) to adjust to room conditions.
