Workshop Wednesday: Understanding Teak Movement — Why Small Gaps Appear (and Why That’s Normal)

by Martin Gilliland

eak is a natural hardwood, and like all wood, it reacts to changes in humidity and temperature. Seasonal expansion and contraction can cause small gaps between planks or slight movement at joints. This is normal and not a sign of poor craftsmanship.

What Homeowners Should Know:

  • Indoor humidity matters: Ideally, maintain 40–60% relative humidity. Low humidity can cause shrinkage and minor cracks, while high humidity can expand planks slightly.

  • Furniture placement: Avoid placing teak furniture near heating vents, radiators, or direct sunlight, which can exacerbate movement.

  • Design considerations: Teak tables with wider planks are more likely to show minor gaps. Narrower planks or solid slabs minimize visible expansion but may cost more.

These natural movements are part of teak’s character. With proper care, they do not affect structural integrity and often add a sense of organic charm to the furniture.
