Contexto local · Mataró
In Mataró, sealed boilers are mandatory since 2007.
Mataró is the Maresme capital and the largest city on Barcelona's north coast. Sea proximity forces siloxane façade paint, stainless hardware and anti-corrosion cylinders on every exterior lock. The old town keeps narrow buildings with spiral staircases that limit material size — we often hoist large furniture up via balcony with pulleys. In the eixample and Cerdanyola, 1960s–80s flats have salt-battered external blinds we replace with marine-coated aluminium. Parking is tough near the centre; we unload first thing in the morning.
