How much does mould removal cost in Ireland?

There is no single price for mould removal, because “mould” covers everything from a patch of bathroom ceiling to a house with five damp rooms. This guide explains the ranges Irish companies publish and what moves a job up or down.

Typical price ranges

These are figures that Irish providers published on their own websites and listings in 2026. They are a guide, not a quote.

The gap between the lowest and highest figure is mostly about size: one bathroom ceiling sits at the bottom of the range, a whole home with several affected rooms at the top.

Ventilation, if it is needed, is priced separately. One Dublin installer publishes about €200 plus the fan for replacing a bathroom extractor and €450 to €550 for a new installation.

What changes the price

• Size. The number of rooms and square metres affected is the biggest factor.
• Surface. Painted plaster is quicker to treat than timber, fabric or crumbling plaster.
• How long it has been there. Old growth goes deeper into the surface.
• Access. Attics, high ceilings and walls behind fitted furniture take longer.
• The cause. If the moisture source has to be fixed, that is part of the real cost of solving it.

What a proper quote includes

A low price is not cheap if the mould is back by spring. A quote worth comparing lists:

1. What was found, with moisture readings or photos
2. The likely cause
3. Which areas will be treated and how
4. What is being done about the cause
5. A fixed price, with anything excluded stated clearly

If a quote only says “mould clean, one room”, ask what happens when it returns. We explain why it does in why mould keeps coming back.

Is it cheaper to do it yourself?

For a small patch on tiles, sealant or a painted ceiling, yes. A cleaner, gloves and a mask cost under €30. For anything larger than about one square metre, or anything that has already come back once, the cost of repeating the job each winter soon passes the cost of fixing it properly. Painting over it is the most expensive shortcut, as covered in can you paint over mould?

How we price

Our survey is free. We inspect the rooms, take moisture readings and send a written report with a fixed quote. You decide after that. Details are on our mould removal in Dublin page.
