Unearthing History: Identifying the Type of Wood in Your Antique Floors

Antique wooden floors can tell a story that spans centuries. They provide a glimpse into the history, craftsmanship, and aesthetic preferences of the era in which they were laid. However, identifying the type of wood on antique floors can be a bit challenging. If you’re looking to restore, maintain, or merely appreciate the wooden flooring in your vintage space, understanding the wood type is crucial. Here are some tips to help you identify the wood on your antique floors.

1. Understanding the Importance of Identification

Historical Value: Recognising the type of wood can give you insights into the time and place where it was popularly used. Certain woods may be associated with particular historical periods or styles.

Maintenance and Care: Different woods have different care requirements. Identifying your floor’s wood type ensures you give it the appropriate care to prolong its life.

Restoration Projects: If you’re restoring or repairing the floor, knowing the wood type helps you match it precisely to maintain the floor’s original charm.

2. Examine the grain pattern.

One of the most distinguishing features of wood is its grain pattern. Each type of wood has a unique grain structure.

  • Straight grain is common in woods like oak and maple. It runs uniformly down the length of the board.
  • Spiralled or Interlocked Grain: Found in woods like mahogany and certain types of rosewood.
  • Wavy or Curly Grain: Often seen in woods like birch or certain cuts of maple.

3. Look at the colour and shade.

Although wooden floors might have faded or darkened over time, their original colour can offer clues.

  • Light Woods: Maple, pine, and ash typically have a lighter hue.
  • Medium Woods: Oak and hickory often fall into this category.
  • Dark Woods: Walnut and mahogany are examples of woods with a naturally darker tone.

4. Check for hardness.

Different woods have varying levels of hardness, which affects their durability.

  • Softwoods, like pine, cedar, and spruce, are less dense and can dent more easily.
  • Hardwoods, such as oak, maple, and cherry, resist dents and wear better.

A simple hardness test involves pressing your thumbnail into a less noticeable part of the floor. If it leaves a mark, the wood is likely softer.

5. Examine the floor’s finish.

Sometimes the type of finish can offer hints about the age and type of the wood. Shellac, for instance, was widely used before the 1920s, which might indicate an older hardwood like oak or heart pine.

6. Consider the plank width.

Older floors often have wider planks. If you notice particularly wide boards, it might suggest that the floor dates back to a time when large, old-growth trees were more plentiful, leading to woods like heart pine or early oak.

7. Refer to historical records.

If your home is historically significant, there might be records detailing the materials used during its construction. Checking local archives or historical societies could offer valuable insights.

8. Seek expert advice.

If in doubt, consider consulting an expert. Wood flooring professionals or antique restoration experts might be able to identify the wood type by examining a small sample.

9. Utilise modern technology.

Today, there are mobile apps and devices that can help identify wood types based on grain patterns, colours, and other factors. While not always 100% accurate, they can be a helpful tool in your identification journey.

10. Consider the Region and Era

Certain woods were more accessible or popular in particular regions or during specific time periods. For instance, in the American South, heart pine and oak were prevalent. Knowing the history of your home’s location can help narrow down the possibilities.

11. Check for knots and imperfections.

Wood naturally has knots, burls, and other imperfections. The size, shape, and frequency of these can often give hints about the type of wood.

  • Pine characteristically has larger, more noticeable knots.
  • Oak possesses a unique scatter of knots and a distinct medullary ray pattern.
  • Cherry typically has a smoother surface with fewer knots.

12. Pay attention to the wood’s smell.

While this might sound unconventional, different woods have unique smells, especially when freshly cut or sanded. If you’re restoring the floor and have exposed some fresh wood, take a whiff:

  • Cedar has a strong, aromatic scent.
  • Pine: Gives off a fresh, sappy smell.
  • Mahogany has a subtle, sweet aroma.

13. Assess the weight and density

If you have access to any leftover or spare pieces of the floor, assessing the wood’s weight can be a clue. Denser woods like oak and walnut are noticeably heavier than lighter woods like pine or spruce.

14. Examine the underneath or the side cuts.

Sometimes, the top of the floorboards may be too worn, polished, or stained to reveal their true nature. If possible, examining the side or the bottom (in cases of accessible crawl spaces) might show the wood in its more unaltered state, making identification easier.

15. Note the reaction to light.

Certain woods darken when exposed to sunlight for extended periods. For instance:

  • Cherry: It tends to darken considerably with sun exposure.
  • Oak: Might develop a golden patina.
  • Maple typically retains its colour better than most other woods.

By understanding how your floor reacts to light, you can make a more educated guess on its type.

16. Test with chemicals

As a more advanced method, certain chemicals react differently with various woods. For instance, a diluted solution of ferrous sulphate will darken woods like oak but have little effect on woods like pine. However, proceed with caution and always test in an inconspicuous area if choosing to go this route.


Identifying the type of wood on antique floors is a blend of art and science. It requires a keen eye, some historical knowledge, and occasionally expert advice. By determining the wood type, you not only deepen your appreciation of the floor’s history but also ensure it receives the care it needs to continue shining for years to come. Whether you’re a homeowner, A Wood Floor Restorer, or an antique enthusiast, the journey of discovery adds another layer to the rich tapestry of the past that lies beneath your feet.
