Sheldon occupies Chippenham's eastern fringe with mild exposure. The M4 proximity brought development in multiple phases, creating a mixed age profile where maintenance needs vary significantly property by property.
Post-war and 1960s properties have concrete tile at the nail sickness threshold. 1980s properties have flat roof extensions now 35–45 years old. 1990s stock is entering the first maintenance cycle.
Three parallel maintenance categories: nail sickness on the oldest stock, felt flat roof failures on 1980s extensions, and fascia deterioration on 1960s timber boards. Often multiple categories present on the same property.
Sheldon's mixed build phases mean we arrive at every survey with a broader range of materials than single-era areas — clay tile, concrete profiles, GRP materials and UPVC fascia stock. Pre-sale surveys are particularly popular here.
