Contexto local · Gavà
In Gavà pre-summer maintenance is key.
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.
