Help with mould and damp in Barcelona
We remove mould from walls, ceilings and bathrooms — and when the cause is unclear, we inspect it with professional instruments. Send photos on WhatsApp first and we will say what is worth doing. You can write in English.
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.
Two specialisms
We don’t just remove mould. We investigate why it appears.
Professional damp and mould inspection
Thermal imaging, moisture readings on materials, a borescope where useful and a written report.

What you need

I can see mould or a dark patch
Surface treatment
There is visible mould or a wall damaged by damp. We treat the affected area, strip back what will not hold and restore the finish when the substrate allows it.

It comes back every winter, same spot
Condensation: understand the cause
The mark returns in cold corners, behind furniture or in the bathroom. It is usually moisture from indoor air settling on a cold surface — worth understanding before painting again.

I do not know where the water is from
Damp and mould inspection
The mark returns even after treatment, or it is unclear where it comes from. The visit combines thermal imaging, moisture readings on the materials and, where useful, a borescope, and you get a written report before anything is decided.

Water is coming in right now
This is not our work
An active leak, a burst pipe or a façade or roof problem is solved first by the relevant trade. Treating the surface while the cause is live wastes your money, and we would rather say so.
Tell us the case
If you are torn between two, send us a couple of photos and we will tell you which one fits. Guidance costs nothing.
Real scope
What we do, and what we do not
Saying it up front saves everyone time and money. If your case is in the right-hand column, we will tell you in the first message instead of selling to you.
We do this
- Treat visible mould on walls, ceilings, bathrooms and corners
- Strip back the affected wall and leave the substrate ready to finish
- Anti-mould paint as a final step, on an already prepared surface
- Restore the interior after a leak has been repaired
- Damp and mould inspection with instruments when the source is unclear
We do not
- Repair leaks, burst pipes or plumbing faults
- Waterproofing, roofs, façades and building work
- Injections or barriers against rising damp
- Pest control, medical reports or industrial remediation
- Expert reports, certificates or documents with legal or insurance standing
- Install or service ventilation, extractor fans, MVHR or air conditioning
While the cause is still live, any new finish is short-lived: the relevant trade solves that first, then we talk about the surface. We also do not promise permanent removal, or make claims we cannot demonstrate.
What we do
Work we handle in Barcelona
Typical cases in city flats: dark marks on a wall, peeling paint, damp traces, mould in corners and behind furniture. Sometimes the mark needs treatment; sometimes the wall needs preparing before paint.
No panic and no jargon. We look at photos, say plainly what we see, and suggest work that matches the real condition — not more, not less.
If the photos show a visit or a different service is needed, we say so upfront. A look in Barcelona is free when it genuinely helps.

Where we cover
Barcelona and the coast around it
We are based in Barcelona and that is where most work happens. We also travel the real corridor around it — north through Maresme towards Blanes and Lloret de Mar, south through Baix Llobregat and Garraf towards Sitges and Vilanova i la Geltrú, and inland to the Vallès — after reviewing photos, not as a claim of a local office in every town.
If you own or manage a second home on this coast, the north-coast and south-coast guides cover what a closed property needs checked on return. The town-by-town pages are in Spanish only, at zonas.
FAQ
Frequently asked questions
Short answers. If your question is not listed — write on WhatsApp in English.
Where do I start if mould has appeared in my flat?
Send a wide shot of the room, a close-up of the mark without flash, and when you first noticed it. WhatsApp is fine — you can write in English. That is usually enough to see what makes sense next.
Does it cost anything to look at photos?
No — free and without obligation. If the photos show a visit is needed, a look in Barcelona is also free. We discuss the price after we can see the wall or ceiling.
Can I write in English?
Yes. We read and reply in English on WhatsApp — helpful if that is easier than Spanish.
What does NoMoho not do?
We do not handle active leaks, roofs, plumbing, electrics or structural work. We do not give medical advice, name mould species or promise mould will never return.
How quickly do you reply?
Usually quickly. If we are on a job, it may take up to 2–3 hours. A person replies, not a bot.
