Cada zona de Barcelona tiene sus propias patologías. Estas son las que detectamos más en Sant Just Desvern:
Suelos radiantes con fugas — en chalets de los 2000 con circuitos que han superado su vida útil.
Piscinas con grietas estructurales — en unifamiliares con más de 15 años sin mantenimiento.
Cubiertas inclinadas con filtraciones en encuentros con chimeneas.
Sant Just Desvern es un municipio pequeño del Baix Llobregat, entre Esplugues y Sant Feliu, que sube desde el llano hasta las laderas de Collserola. Alrededor del núcleo antiguo quedan casas de pueblo y alguna masía. Desde los años 60 y 70 crecieron en la parte alta urbanizaciones de casas unifamiliares como La Miranda, y en la parte baja bloques de pisos, entre ellos Walden 7, el edificio de Ricardo Bofill levantado junto a una antigua fábrica de cemento. Después se han sumado adosados y nuevas promociones de pisos.
Si compras en Sant Just, lo más habitual es una casa unifamiliar en pendiente o un piso en un bloque de los 70 en adelante. En las casas, fíjate en los muros de contención, el drenaje del terreno y las humedades en sótanos y garajes, y comprueba que ampliaciones y piscinas estén legalizadas y coincidan con el Catastro. En los bloques, pregunta for la ITE y for las obras de comunidad aprobadas. La inspección técnica inspecciona estructura, cubiertas, instalaciones y aislamiento, y valora la eficiencia energética de las casas grandes con muchos años.
Centre — Casas de pueblo entre medianeras y edificios bajos de distintas épocas. Inspecciona forjados de madera, humedades for capilaridad, cubiertas e instalaciones antiguas.

Walden 7 — Conjunto de viviendas de los años 70 con pisos de distribución singular. Inspecciona el estado de fachadas y terrazas, las humedades y las obras de comunidad previstas.
