Contexto local · Gavà
Many flats in Gavà still have old panels.
Gavà splits into three very different areas. Gavà Centre is 1970s–80s urban housing where most jobs are bathroom refurbs, swapping old aluminium frames for thermally-broken PVC, and reinforcing the electrical panel. Gavà Mar mirrors Castelldefels' seafront, with the same salt exposure. Heading north toward Bruguers, semi-detached homes with garden and pool dominate, with scheduled maintenance (pool, heat pump, irrigation) as the most demanded service. Logistics are easy: wide streets and loading zones with no time limits outside the centre.
