About Ventilation Experts Ireland
For over 15 years we have been Dublin's go-to team for professional mould removal, damp proofing and ventilation installation. Family-run, fully certified and committed to healthier homes across Ireland.
15 Years of Healthier Homes Across Dublin
Ventilation Experts Ireland was born out of a simple belief: every family deserves to live in a healthy, mould-free home. Founded in 2009 by Ciarán O'Brien, we started as a small ventilation installation company and grew into Dublin's most comprehensive indoor air quality specialist.
We are a family-run business and proud of it. That means every job gets the personal attention it deserves — no call centres, no subcontractors, just our own certified team showing up on time and doing the job right.

Areas We Serve
What Our Customers Say
Over 2,000 Dublin homeowners and landlords trust us with their properties. Here is what some of them have to say.
"Absolutely brilliant service from start to finish. Ciarán and his team identified hidden mould behind our bathroom tiles using thermal imaging — something two other companies completely missed. The remediation was thorough and the written report was excellent. Highly recommend."
Declan Farrell
Ranelagh, Dublin 6
"We had a serious condensation and black mould problem in our Victorian terrace. Ventilation Experts installed a full HRV system and treated all affected areas. Six months on and the house is completely transformed — no more condensation, no more mould. Worth every cent."
Siobhán McCarthy
Clontarf, Dublin 3
"Used them for a damp proofing survey before buying a house. The report was incredibly detailed and actually saved us from a very expensive mistake — the property had serious rising damp that the seller had not disclosed. Professional, honest and thorough."
Padraig O'Sullivan
Tallaght, Dublin 24
"Seán installed extractor fans in our kitchen and bathroom and the difference is night and day. No more steamed-up mirrors, no more condensation on windows. The team were tidy, professional and finished ahead of schedule. Five stars without hesitation."
Fiona Byrne
Dundrum, Dublin 14
"Called them on a Friday evening about a severe mould outbreak in our rental property. They had a team on-site by Saturday morning. The emergency response was incredible and the tenants were back in a safe, clean property within 48 hours. Cannot thank them enough."
Tomás Ní Bhriain
Swords, Co. Dublin
"Niamh carried out a full damp proofing treatment on our basement conversion. She explained every step clearly, the work was immaculate and the 10-year guarantee gives us complete peace of mind. Genuinely the best tradespeople we have ever hired."
