Sealing Joints and Cracks in Barcelona
A leak near a window or an open joint isn’t always fixed by simply painting over the stain. We inspect the exterior surface and the condition of the substrate to assess the sealing of joints and cracks in Barcelona, as well as in the neighborhoods of Les Corts.

Our technical team performs a detailed inspection to identify all vulnerable areas, such as expansion joints, structural cracks and critical infiltration points.

Antes de pedir una valoración
¿Cuándo conviene revisar el sellado?
Cuando entra agua al llover, aparecen fisuras alrededor de un encuentro o el sellante se separa del soporte. La mancha no confirma por sí sola el punto de entrada: conviene revisar juntas, remates y grietas próximas.
¿Basta con poner silicona encima?
No siempre. La preparación de la superficie, el movimiento de la junta y la compatibilidad del producto condicionan el resultado. Si la fisura responde a un problema estructural, el sellado no sustituye su evaluación técnica.
¿Qué fotos ayudan a valorar una filtración?
Una vista completa de la ventana o fachada y un detalle de la humedad, tomados desde un lugar seguro. Explica si ocurre solo con lluvia, si empeora con viento y desde cuándo sucede.
El alcance y el presupuesto dependen del estado del edificio, la superficie o tramo afectado y el acceso. Las fotografías ayudan a preparar la consulta, pero una valoración definitiva puede requerir revisión presencial.
Para ampliar la información, consulta nuestra guía relacionada con este servicio.
Si el problema está relacionado con otra zona del edificio, consulta el servicio de impermeabilización de terrados. Para una incidencia activa, tenemos atención de urgencias 24 horas. La atención no implica llegada inmediata garantizada ni permite intervenir sin valorar la seguridad.
