Contexto local · Terrassa
In Terrassa pre-summer maintenance is key.
Terrassa has a strong industrial identity: 19th-century textile factories have been converted into lofts and offices in Can Boada and l'Antic Poble de Sant Pere. There we work with 5 m ceilings, wrought-iron beams and original slabs that can't take big point loads — any mezzanine hangs off new steelwork. The rest of the city is 1970s–80s mid-rise with the usual insulation issues. At ~280 m altitude winters are cold and heating demand — heat pumps, biomass, boilers — is high. C-58 access dictates booking order: first slots local, second slots Barcelona.
