Why mould is so common in Dún Laoghaire homes
Three local patterns account for most of the calls we get from the A96 area. First, solid brick or stone walls with no cavity: they stay colder than the air in the room, so moisture from cooking, showers and breathing condenses on them, especially in corners, behind wardrobes and on the window reveals of north facing rooms. Second, retrofits done in the wrong order: new sealed windows and draught proofing in a house that was designed to breathe, with no ventilation put in to replace the draughts. Third, flats and bedsits carved out of larger houses, where a bathroom or kitchen has no window and the extractor, if there is one, vents into a void or does not pull at all. Sea air does not cause mould by itself, but a damp, cool climate means walls dry out slowly once they are wet, so the fix has to be about moving air, not just wiping surfaces.

What mould removal costs in Dún Laoghaire
Mould removal starts from €350. The final price depends on how many rooms are affected, how far the growth has gone into plaster, sealant or fittings, and what is needed to stop it returning, usually a working extractor fan or a ventilation unit. Send a photo of the worst wall or ceiling with your Eircode through the form and we email a preliminary quote within 24 hours; no visit is needed to get started. We give a 1 year warranty on the remediation work when the full recommended scope is completed. Prices, process and the warranty terms are the same as on our Dublin mould removal page.

How we remove mould in a period house or a flat
Every job follows the same five steps: a survey with moisture readings and thermal imaging to find the cold and damp spots that feed the growth; finding the cause, which in most homes is moisture that never leaves rather than a leak; treating and cleaning the affected surfaces and replacing what cannot be saved, such as mouldy silicone; fixing the cause with a correctly sized extractor fan, a single room heat recovery unit or whole house ventilation; and, where it helps, anti mould paint on the treated surfaces.
In older houses we work around original plaster, cornices and timber: the extract route is planned with you before anything is drilled, and we show you where the duct or through wall unit will go. In flats we check the building ventilation first, because a shared stack or a blocked trickle vent can be the real cause.
Steps We Take to
Landlords, tenants and the rest of the south coast
A large share of Dún Laoghaire homes are rented. Under Irish rental standards a landlord has to deal with damp and mould and provide adequate ventilation, and a written report that names the cause is worth more than a painted over ceiling. We survey, remediate and document the work for landlords, letting agents and management companies, and we explain to tenants what they can change day to day. A written report from our mould survey names the cause and the fix.
We cover the whole south coast from Blackrock to Killiney, including Monkstown, Glenageary, Sandycove, Glasthule, Deansgrange and Dalkey. For the full Dublin service, prices and the warranty terms, see mould removal in Dublin.
