In Badalona older buildings have cast-iron stacks.
Badalona mixes a seafront strip with very different working-class neighbourhoods. In Casagemes and Centre we keep early-20th-century buildings with street balconies and original joinery many owners want restored rather than replaced — annual teak oiling is already in the quote. In Llefià and La Salut we deal with dense 1960s–70s blocks whose single-phase panels max out when air-con or an induction hob is added; we recommend a line upgrade first. Sea air rusts hardware and external blinds fast, so we always quote marine-grade cylinders and guides. Beach traffic in summer pushes us to first- or last-slot visits.
