Cavity walls become standard, generally with clay tile or slate roofs, cast-iron rainwater goods and suspended timber ground floors. Bay-fronted semis dominate.
What we usually find. Wall-tie corrosion and bridged cavities are the usual structural concerns, and sub-floor ventilation is often obstructed by later paths, patios or extensions, which brings damp and timber decay to the ground floor. Original roof coverings are typically at the end of their life.
Worth knowing. Cavity wall insulation retrofitted into this stock can cause damp on exposed elevations if the wall was not suitable. Establishing whether the cavity was filled, and when, is worthwhile.
