Chartered surveyors in Poulton-le-Fylde

Post-war rebuilding, largely cavity-walled, but including system-built and non-traditional types — reinforced concrete, steel frame and prefabricated panels — put up quickly to address the housing shortage.

What we usually find. The conventional stock of this period is usually straightforward. Non-traditional construction is a different matter: some types are designated defective, and most lenders treat them differently or decline them, which affects both mortgageability and resale.

Worth knowing. Identifying the construction type is the first job on anything of this age that does not look conventionally built. A Level 3 survey is normally the right choice here, and lending should be confirmed early.

Cavity walls with insulation increasingly built in, flat-roofed elements such as garages, dormers and rear additions, and a broader range of manufactured materials.

What we usually find. Flat roofs of this era are frequently on their second or third covering and are a common source of water ingress. Textured coatings applied before the mid-1980s may contain asbestos, as may some cement products, soffits and floor tiles.

Worth knowing. Asbestos-containing materials are usually safe if undisturbed and in good order, but they matter a great deal if you intend to remove ceilings, take down a garage or open up the layout.
