Radon Remediation in Dublin
Compare up to 4 radon remediation professionals in Dublin. Free, no obligation.
Dublin's housing stock is Ireland's most diverse, spanning from Georgian terraces in the city centre (1750s-1830s) through Victorian and Edwardian suburbs (1840s-1910s), inter-war and post-war council housing (1930s-60s), suburban estates (1960s-2000s), Celtic Tiger apartments (1998-2008), and modern high-density developments. Each era presents distinct characteristics for home service providers: Georgian homes have solid brick walls, original timber floors, and sash windows. 1960s-70s suburban semis have cavity block walls, often with minimal insulation, and are the most common candidate for energy retrofits. Celtic Tiger-era apartments may have building defects from the construction boom. The sheer density and variety of Dublin housing means every type of home service has strong, consistent demand.
Dublin has a temperate maritime climate with relatively low rainfall by Irish standards (approximately 750mm annually), though this still exceeds most UK and continental European cities. The east-facing position means less rain than the west coast but more exposure to cold easterly winds in winter, which can affect heating demand and frost risk. Sea proximity moderates temperature extremes. South-facing properties benefit from good solar exposure, making Dublin viable for solar PV installations. Urban heat island effects mean the city centre is typically 1 to 2 degrees warmer than outer suburbs.

Dublin is Ireland's busiest market for all home services due to population density and property values. High demand means competitive pricing for standard trades but premium rates for specialist services. Property values drive significant investment in home improvements, with homeowners willing to spend more on quality materials and finishes. The four Dublin local authorities (City, Dun Laoghaire-Rathdown, Fingal, South Dublin) each have distinct planning approaches. Conservation areas are extensive in Dublin city centre, Dun Laoghaire, and parts of Fingal. Dublin prices for home services are typically 15 to 25% above the national average, reflecting higher labour costs, travel time, and material delivery costs in the urban environment.

Typical costs for radon remediation in Dublin (prices may vary (typically 50% above national average)):
| Service | Typical Cost | Notes |
|---|---|---|
| Radon test kit | €75 | €120 | Type of detector |
| Active radon sump system | €1,200 | €2,250 | Property type, access |
| Radon barrier membrane | €2,250 | €4,500 | Floor area, access |
Radon sump installation costs depend on your floor type (concrete slab vs suspended timber), the size of your home, and the accessibility of the sub-floor space. A single sump with an inline fan typically handles a standard semi-detached house. Larger or irregularly shaped homes may need two sumps. Radon barrier membranes for suspended floors are more expensive due to labour and material costs. Running costs for a sump fan are minimal: approximately €30 to €50 per year in electricity.

Radon Remediation FAQs for Dublin
An active radon sump system for a standard semi-detached house costs €800 to €1,500 installed. More complex installations (larger homes, multiple sumps, difficult access) can reach €2,000. Radon barrier membranes for suspended timber floors cost €1,500 to €3,000 depending on the floor area. Follow-up testing should be included in the price or costs €50 to €70 separately. Annual running costs for the sump fan are approximately €30 to €50.
You must test. Radon is invisible and odourless, so there is no way to detect it without a measurement device. The EPA sells postal test kits for approximately €50. Place the detector in a frequently used ground-floor room for three months, then return it for analysis. The EPA's radon map at epa.ie gives a general indication of risk by area, but individual homes vary enormously even within the same street. Every home in Ireland should be tested regardless of area risk level.
The Irish reference level is 200 Bq/m³ (becquerels per cubic metre). Homes above this level should take remedial action. However, there is no truly safe level of radon: risk increases proportionally with concentration and duration of exposure. The World Health Organisation recommends a reference level of 100 Bq/m³. If your test result is between 100 and 200, remediation is advisable, especially if you are a long-term resident or if smokers live in the home (radon and smoking together multiply lung cancer risk significantly).
A properly installed active sump system reduces radon levels by 90% or more in the vast majority of cases. A home with a pre-remediation level of 800 Bq/m³ can be brought below 80 Bq/m³. The system works continuously and maintains low levels as long as the fan is running. Post-installation testing confirms the reduction. If the initial system does not achieve sufficient reduction (rare), modifications or a second sump can be added.
High radon is not a legal disclosure requirement when selling property in Ireland. However, informed buyers (especially those with young families) are increasingly testing during the purchase process. Having a remediation system already in place, with documented post-installation test results showing low levels, gives buyers confidence and removes a potential objection. Remediation is inexpensive relative to property values and is a net positive for saleability.
The EPA radon map shows that high-radon areas are concentrated in the west, northwest, and parts of the midlands, with notable hotspots in counties Galway, Mayo, Sligo, Clare, Kerry, Waterford, Kilkenny, and Carlow. However, elevated radon has been found in every county in Ireland, including Dublin. Ground conditions, not geography alone, determine radon levels. The only reliable way to know your home's level is to test it.
