You just got your hands on beautiful hardwood flooring. It’s the perfect color, texture, and finish. But before you start the installation, there’s one critical step you can’t skip: acclimation.
Hardwood is a natural material that expands and contracts based on humidity and temperature. If you install it straight from the box without giving it time to adjust, you risk warping, gapping, or buckling. That’s why acclimation is essential.
How long should hardwood floors acclimate?
Most manufacturers recommend acclimating hardwood flooring for at least 3 to 5 days before installation. But that’s not a one-size-fits-all answer. The ideal timeframe depends on factors like wood species, plank thickness, and the climate in your home. In humid areas, it may take a full week for the wood to settle. In drier climates, 72 hours might be enough. The key is patience—rushing this step could lead to costly repairs down the road.
How to acclimate hardwood flooring correctly
It’s not just about waiting. You need to create the right conditions for the wood to adjust properly. Here’s how:
- Bring it inside: Keep the flooring in the space where it will be installed. Don't leave it in the garage, basement, or another area with different humidity levels.
- Stack it properly: Open the boxes and spread out the planks in small stacks. This allows air to circulate around each piece.
- Match the room’s climate: Maintain the indoor temperature between 60-80°F and humidity between 30-50%—similar to how you’ll keep the room after installation.
- Check moisture levels: Use a moisture meter to compare the moisture content of the wood and the subfloor. They should be within 2-4% of each other for solid hardwood and less than 2% for engineered wood.
What happens if you don’t acclimate your hardwood floors?
Skipping acclimation can be a disaster. If the wood absorbs too much moisture, it expands, leading to cupping or buckling. If it dries out too much, it shrinks, leaving gaps between planks. Either way, you’ll end up with a floor that doesn’t look or function the way it should—and fixing these issues? Expensive and frustrating.
Solid vs. engineered hardwood: does it make a difference?
Yes! Solid hardwood flooring is more prone to expansion and contraction, so it needs a longer acclimation period—often at least 5-7 days. Engineered hardwood, with its layered construction, is more stable and may only need 24-48 hours. Always check the manufacturer’s guidelines to be sure.
When can you skip acclimation?
In rare cases, you might not need acclimation. Some pre-acclimated hardwood flooring is designed for immediate installation. If the wood was stored in a controlled environment with matching humidity levels, you might be able to install it right away. But don’t assume—check the manufacturer’s recommendations first.
