The Science Behind Wood Expansion: Why Acclimating Your Hardwood Matters

Why Does Hardwood Expand and Contract?

Wood is a natural material that reacts to its environment. It absorbs moisture when humidity is high and releases it when humidity drops. This causes hardwood flooring to expand and contract. If not properly acclimated before installation, the wood may shrink or swell, leading to gaps, cupping, or warping over time.

The Importance of Acclimating Hardwood Floors

Acclimating hardwood means allowing the wood to adjust to the temperature and humidity of your home before installation. This step is crucial in Elk Grove Village and the Chicagoland area, where seasonal humidity fluctuations can be extreme.

Skipping this process can lead to:

• Gapping: Wood shrinks in dry conditions, creating noticeable gaps.

• Cupping: Wood absorbs excess moisture, causing the edges of planks to rise.

• Buckling: Severe expansion may cause wood to lift from the subfloor.

How Long Should Hardwood Acclimate?

At Tom & Peter Flooring, we recommend acclimating your hardwood for at least 3–7 days before installation. The exact time depends on the wood species and the climate conditions in your home.

The Right Way to Acclimate Hardwood Flooring

1. Store Inside – Keep the flooring in the room where it will be installed. Never leave it in garages or basements.

2. Stack Properly – Open the boxes and spread out the planks for better air circulation.

3. Check Humidity Levels – The indoor humidity should be between 30%–50% for best results.

4. Monitor Moisture Content – Professional installers will use a moisture meter to ensure the wood is ready.
