Finishes, vital lines and structure
Finishes are the visible parts of the home: paint, plaster, floors and tiles, doors, windows, cabinets and fittings.
The vital lines are the networks, pipes and elements that carry electricity, water and fuel such as gas.
The stability of the structure concerns the elements that hold the building up, as Ley 400 de 1997 defines them. A crack in a plastered wall is often a finish; ask the builder to check whether it is structural.
