When transitioning between different wood floors, you might find yourself installing new hardwood flooring in some areas of the home while retaining old wood floors. Use techniques such as contrast, different patterns, and movable features to create a seamless transition between the old and new. Finding a wood grain that complements the existing flooring is also a good way of transitioning between old and new floors.  If you’re not keen on using two different wood floors, consider sanding and refinishing your existing hardwood flooring before replacing with new wood floors.
