Module: Moisture in materials

External timber steps and handrails are exposed to all weather conditions, including regular wetting and drying and high levels of UV light. Regular wetting and drying causes swelling and shrinkage of the timber, while changes in ambient temperature results in continual thermal expansion and contraction. The constant movement of the timber causes warping and cupping, joints to open up, nails to pop and fixings to become loose. In addition, timber that remains wet for extended periods of time becomes slippery, and rotting may occur.

This Good Repair Guide identifies some of the common problems and repair options for external timber steps and handrails. When damage to external steps is extensive, the best option is often full replacement.

This module covers design and construction requirements for landings, including quarter and half landings.

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.
