What can a springy or uneven timber floor indicate?
A springy or uneven floor can have several causes, including loose boards, weakened joists, movement at supports or changes in the subfloor. Look for soft timber, staining, unusual smells or signs of poor ventilation, but avoid lifting boards unless it is safe and appropriate. The floor structure and moisture conditions below should be inspected before deciding whether local repairs or wider replacement are needed. See timber joist repairs for related work.
