Contexto local · Santa Coloma de Gramenet
In Santa Coloma de Gramenet many flats still have old aluminium wiring.
Santa Coloma de Gramenet is almost entirely 1960s–70s buildings put up for internal migration, with 8–14-storey blocks in Singuerlín, Riu Nord and Llatí. That vintage explains what we see most: carbonation damp on garage ceilings, aluminium wiring that needs checking before any work, and fibre-cement stacks that need a special protocol to touch. In bathroom refurbs we routinely uncover tiling stuck straight to mortar with no membrane, which forces us to chase further than expected. The slope toward the Besòs limits van access on some central streets.
