Modern insulated construction to current Building Regulations, normally with a ten-year structural warranty, high levels of airtightness and mechanical ventilation in the newest homes.
What we usually find. Structural defects are uncommon; the recurring themes are condensation and interstitial damp where airtight construction meets ventilation that is switched off or never commissioned, along with workmanship snags in newer developments.
Worth knowing. On flats and any property with external wall insulation or cladding, establish the position on fire safety documentation early, as it can hold up a sale regardless of the building’s condition.

Mostly solid-wall terraces and early semis, with cavity construction beginning to appear toward the end of the period. Slate damp-proof courses are usual, along with timber sash windows and slate roofs.
What we usually find. Much the same pattern as the older stock, with the addition of early cavity walls where wall ties may now be corroding. Original roof coverings are commonly nearing replacement, and rear additions of this age are frequently built to a lower standard than the main house.
Worth knowing. Where a property has been re-roofed or extended, the junction between old and new is normally where water gets in. It is worth establishing what was done and when.
