Mould removal cost in Barcelona: what drives the price
You want a number. The honest answer is that it depends — and this page explains exactly on what, instead of inventing a figure that would not match your flat.

When to contact us
You can write in English — we reply in English. We usually reply quickly. If we are on a job, it may take up to 2–3 hours.
Why we don’t publish a fixed price online
Search for “mould removal cost” — or “mold removal cost”, if you spell it the American way — and you will find plenty of tables with a headline average or a price per square metre. In practice these numbers usually blend together very different jobs — a small patch of surface cleaning and a much larger repair with structural causes — under one figure. Presented online, without seeing the flat, that average tells you very little about your own case.
We would rather be honest about that than post a number that does not hold up once we actually look at the wall or ceiling.
What actually moves the price
A few things genuinely change what a job costs:
- Area affected and number of rooms. More surface means more time, more product and more paint.
- Type of surface. A plastered wall, a painted ceiling and furniture each need slightly different handling.
- How damaged the paint or plaster is. Mould on otherwise sound paint is a cleaning-and-repaint job. Paint that has bubbled, flaked or come away usually needs the base repaired first, which adds work.
- Access. A wall at normal height is quicker to reach than a high ceiling, a stairwell, or a corner behind fixed furniture.
- Whether repainting is included. Treating the mould and repainting the area is often part of the same visit; that scope affects the quote.
- The likely cause and how it behaves. A one-off mark with an already-resolved cause is different from a recurring one that may need repeat treatment.
None of this produces a single number we can quote in the abstract — which is exactly why we look at the actual case.
Surface work vs a structural cause
It matters to separate two things. Cleaning the mould and repainting the surface is what we do — it deals with what you can see and touch. A structural cause of damp, such as an ongoing leak or capillary damp coming up from the ground, is a different kind of work, usually needing a different specialist. If we think a case looks structural rather than surface-level, we will say so plainly rather than treat a symptom that will simply return. This page is only about the surface side of the price.
This split also explains why two flats with a similar-looking mark can get quite different quotes. A wall with a resolved, one-off cause and sound plaster underneath is a straightforward surface job. A wall that keeps producing new mould however often it is cleaned usually points to a cause that surface treatment alone cannot fix — and no honest quote for cleaning and repainting will make that cause disappear.
What the free assessment includes — and what it doesn’t
A free assessment usually means: you send photos and a short description on WhatsApp, or we take a look on site; we estimate the area and the condition of the surface; we explain what the treatment and repaint would involve; and you get a personalised quote with no obligation to book.
It does not include thermal imaging, moisture-meter surveys, lab testing, or a structural diagnosis — those are outside what a surface treatment service does, and we will tell you if your case needs one of those instead.
How to get a real answer fast
The quickest route to an honest number is mould removal or anti-mould painting as a starting point, with a few photos sent over. Useful to include: a wide shot of the room, a close-up of the mark, and a short note on how long it has been there and whether it has come back before. If you are not sure this is the right kind of case for us, when to call a mould specialist can help you check first.
