You saved for a rainy day. In Ireland, that’s most of them. Plain fixes for damp and mould in Irish homes, with every cost worked out in euro.
RainyDay.ie is a practical guide to the problems Irish weather leaves inside the house: windows that stream every morning, black spots creeping across a bedroom wall, washing that won’t dry from October to March, and the power cuts that come with every big storm.
Every guide is written for Irish homes and Irish electricity prices.

Why every figure here is in euro
Ireland has the dearest household electricity in the EU, according to Eurostat.
Every cost on this site is worked out from the wattage, the hours and Irish unit rates, and the sum is always shown.
It’s the same with the weather. Met Éireann describes cloudy, humid weather with rain, carried in on Atlantic depressions, as typical of the Irish climate.
That’s why drying clothes outdoors is a summer luxury, and why condensation is a winter routine rather than an occasional nuisance.

How we work
RainyDay.ie is written and edited by James Dunne. We don’t test products in our own homes; we build each guide from manufacturers’ published data, Irish public sources such as the HSE and the RTB, and Irish electricity prices.
How we research explains the method, and about us explains who we are.
Some links on this site earn us a commission at no extra cost to you. It never decides what we recommend.
