Contexto local · Cornellà de Llobregat
In Cornellà de Llobregat pre-summer maintenance is key.
Cornellà de Llobregat grew fast between 1965 and 1985 and most of its buildings fall in that bracket: 6–10-storey blocks in Centre, Almeda and Sant Ildefons. The big recent change is Next Generation-funded refurbs, mostly heat pumps and external wall insulation; our installers process the grants and sign the energy certificates. We still find old town-gas inlets in kitchens that need auditing before any work. Cornellà has decent loading zones and ample block parking, which keeps long-day jobs cheaper than dense L'Hospitalet or Santa Coloma.
