Renovation in Mataró and the Maresme
The Maresme is where Barcelona goes at the weekend, and where a good number of foreign owners keep a second home. Living close to the sea changes the materials, not just the view. Here the salt decides what lasts.

Short answer
What a renovation costs in Mataró and the Maresme
A full renovation on the Maresme runs from €780 to €1,600 per m², so an 80 m² flat comes out between €62,400 and €128,000 over 10–14 weeks on site. Two line items appear here that do not exist inland: marine-grade joinery and ironmongery, and a chemical damp-proof course where the property sits against the slope. For a second home the single best thing you can install is leak detection with an automatic shut-off — a burst pipe in a house nobody visits for three months costs more than the renovation.
| Item | Why it appears here | Indicative cost | Typical duration |
|---|---|---|---|
| Full flat renovation | Standard scope | €54,600–€144,000 | 10–14 weeks |
| Terrace waterproofing | Flat roofs stain the neighbour below | €95–€130/m² | Needs dry weather |
| Chemical damp-proof course | Ground floors cut into the slope | Costed by metres of wall | Weeks of drying |
| Repainting after the wall dries | 80 m² flat | €1,400–€2,400 | End of the programme |
| Leak detection, automatic shut-off | Homes closed for months | within a set-up from €1,900 | One day on site |
What running it from abroad actually requires
- A written fixed quote after the technical visit, not a range that drifts later
- Decisions grouped into batches — tiling, worktops, socket positions — so a time-zone gap never stops the site
- The comunidad de propietarios file, including liability policy and noise hours, submitted before the site opens rather than after access is refused
Salt air
What the sea decides
Proximity to the sea accelerates the corrosion of metals and degrades finishes that would last twice as long inland. It is not a detail to be settled at the end of the job. It sets the working life of everything you install.
Choices that have to be right
- External joinery: PVC, or aluminium with a high-durability lacquer certified for marine environments
- Ironmongery and screws: stainless, never ordinary steel
- Balustrades: marine-grade stainless or lacquered aluminium, not painted steel
- Outdoor taps and terrace showers: finishes rated for the exposure
- Awning and pergola anchors: stainless, or they work loose within a few years
The mistake visible along the whole coast
A painted steel balustrade on a terrace three hundred metres from the water. Three years later it is rusting and staining the façade beneath it. The correct specification costs slightly more on day one and lasts decades rather than years.
Damp and empty months
Ground floors, hillsides and houses that stand closed
The Maresme rises steeply from the shore, so a great deal of property is single-storey or cut partly into the slope. Rising damp is the most repeated problem in the whole comarca, and a house that stands empty for months makes every symptom worse. It is also the defect most often painted over shortly before a viewing, which is why the wall bases are the first thing we look at.
How damp is actually solved
- A chemical damp-proof course injected at the base of the wall
- Perimeter drainage wherever there is external access to excavate
- Breathable internal finishes, not impermeable ones
- Ventilation, to carry away the moisture the wall releases
If the house is closed for part of the year
Second homes fail differently from permanent ones. Leak detection with an automatic water shut-off is the best single thing to install here, because a burst supply pipe in a house nobody visits for three months does more damage than the renovation cost. Programmed ventilation and remote temperature control follow, so that you arrive to a dry, conditioned house instead of to a smell.
Planning a renovation you will not attend
A Maresme project for an owner who lives abroad is planned backwards from the visits you already have booked. Demolition and first fix are the phases that need no decisions from you, so they run while you are away; the choices that genuinely benefit from being seen in person, such as tiling, worktops and the position of sockets and lighting, are grouped so they can be settled in a single trip or, if that is not possible, from a set of photographs and samples posted out. The rule that makes it work is simple and it does not change: nothing outside the signed quote is executed without written approval, so the figure you agreed is the figure you pay.
Frequently asked
Renovations in Mataró: common questions
A full renovation of an 80 m² flat runs from €62,400 to €128,000. On the coast it is worth spending a little more on joinery and ironmongery, and that difference pays for itself within a few years.
PVC, or aluminium with a high-durability lacquer certified for marine environments, together with stainless ironmongery. Ordinary steel and low-grade lacquers degrade within a few years in this exposure.
With a chemical damp-proof course injected at the base of the wall, perimeter drainage where excavation is possible, and breathable internal finishes. Anti-damp paint over a wall with active capillary rise blisters within a year.
Leak detection with automatic water shut-off first, then remote temperature control and programmed ventilation for the closed months. Keypad access is also worth having, so that you can let someone in without posting keys abroad.
A basic set-up with leak detection, remote heating control and a few scenes starts at around €1,900. A typical whole-flat installation is about €4,500, and a full house with zoned climate control, blinds and lighting reaches €12,000.

What we learn on site
Real housing problems in Barcelona, explained by the people who fix them.
Pladur
Pladur appears in every Spanish renovation quote and confuses every foreign owner. It is simply a brand of plasterboard that became the generic word — and well executed, it beats brick partitions at almost everything.
Cost by flat size
Price per square metre is useful for orientation and misleading for decisions: several of the biggest line items cost roughly the same in a 70 m² flat as in a 120 m² one, and they are exactly what breaks the quick mental maths.
Covering kitchen tiles
Spanish kitchens are tiled floor to ceiling, and ripping that out in a period building is never a small job. Covering the tiles instead is quick and legitimate — as long as you know which systems survive what sits behind a sink.
