Radon Remediation in Kildare

Kildare is Ireland's fastest-growing commuter county, with massive residential development from the mid-1990s onward. Towns like Naas, Celbridge, Maynooth, Leixlip, Newbridge, and Kilcock have extensive estates of 1990s-2010s semi-detached and detached houses. Many of these homes are now 15 to 25 years old and reaching the point where boilers, windows, and insulation need attention. Older towns (Athy, Kildare, Monasterevin) have pre-1970s housing requiring more full upgrades. The Curragh area has military housing with specific characteristics. Rural Kildare has flat, fertile farmland with scattered one-off houses.
Kildare is one of Ireland's drier and sunnier counties, with rainfall of approximately 750 to 850mm annually. The flat terrain provides consistent solar exposure, making it excellent for solar PV installations. The inland location means colder winters than coastal counties, with more frost days, which affects external render, paving, and plumbing (frozen pipe risk). The flat landscape means less wind exposure than western counties but also less natural shelter for individual properties.

Kildare's commuter-driven property market means strong home values and significant demand for home improvements. The concentration of relatively modern housing (1990s-2010s) creates a specific market for mid-life upgrades: boiler replacement, window upgrades, kitchen and bathroom renovations, attic conversions, and energy retrofits. Kildare County Council manages planning and has been supportive of energy upgrade programmes. The M7 and M4 motorway corridors concentrate development along specific routes. Contractor competition is healthy with many Dublin-based trades serving the county.

Typical costs for radon remediation in Kildare (prices may vary (typically 10% above national average)):
| Service | Typical Cost | Notes |
|---|---|---|
| Radon test kit | €55 | €88 | Type of detector |
| Active radon sump system | €880 | €1,650 | Property type, access |
| Radon barrier membrane | €1,650 | €3,300 | 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 Kildare
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.
