Contexto local · Esplugues de Llobregat
Many flats in Esplugues de Llobregat still have old panels.
Esplugues de Llobregat is mixed: the historic centre by the riera keeps two-storey houses with courtyards, while Can Vidalet and La Plana are mid-size 1970s–80s blocks. A lot of our recurring work comes from single-family homes in Finestrelles and Ciutat Diagonal: pool service, motorised blinds, gardens and sun-exposed external joinery. Diagonal campus and several international schools nearby also bring short-stay tenants who need quick repairs before the deposit is returned. Private parking in most communities makes logistics easier than central Barcelona.
