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.
In short
Worth knowing early
- We work in Barcelona; you can write in English
- We do not promise “forever” or scare without reason
- Repair and painting only when they are needed
- Photos on WhatsApp first, to avoid unnecessary work

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.
