2026 prices

What does a Maresme renovation cost?

Between 900 and 1,600 €/m² depending on flat vs house, coastal joinery (salt) and whether the roof is in scope. A 180 m² house is not priced like an Eixample flat: envelope, garden and often its own drainage. Guides: Barcelona prices and efficient homes in Maresme.

Coast

What changes when you renovate by the sea

Salt and joinery

Cheap windows fail in two winters. We specify thermal-break frames and coastal ironmongery, not an inland-flat spec.

Houses and roofs

Many jobs are houses, not flats. Roof, rainwater and rising damp enter the briefing on day one.

Office in Premià

c/ Gibraltar, 44. Real site visits. Maresme is not run well from a switchboard 40 minutes away.

Different towns, different permits

Premià, Alella and Mataró do not share a counter. We file by town hall, not with a Barcelona-city template.

Method

From Premià across the county

Survey, itemised budget, local permits, build and tracking panel. For passive-house or aerothermal work: passive houses and aerothermal on the coast (same humidity logic).

FAQ

Common questions in El Maresme

Is it cheaper than Barcelona city?

Labour and logistics are usually more reasonable than an Eixample walk-up. Coastal joinery is not cheaper.
