Good Repair Guide: Subfloor timber

A bouncy or springy floor or a floor that is noticeably uneven is often the first indication that there may be a problem with the subfloor framing.

Subfloor timbers include joists, bearers, wall plates, jack studs, braces and stringers. They are structural components of a building, and any damaged or understrength subfloor timbers must be repaired or replaced regardless of the cause.

This Good Repair Guide looks at the causes of common problems with subfloor timber and outlines the repair options.
