Irish families face another Christmas in crumbling homes as defective blocks crisis persists

Families across parts of the Republic of Ireland have said they are bracing for yet another Christmas in homes they describe as unsafe, deteriorating and literally “crumbling around them”, as the long-running defective concrete blocks crisis continues to take its toll.

Thousands of houses—predominantly in counties Donegal, Clare, Limerick, Mayo and Sligo—have been affected by concrete blocks containing water-absorbing minerals such as pyrite and mica. Over time, these minerals expand when exposed to moisture, causing bricks to crack, walls to weaken and, in the most severe cases, homes to become structurally unsound.

For many families, the damage has progressed beyond repair. Entire properties have been condemned and demolished, leaving homeowners displaced and facing prolonged uncertainty over rebuilding and financial support.

Residents say the crisis has robbed them of security and peace of mind, particularly during the festive season. Some report living with visible cracks running through walls, crumbling masonry and persistent fears about safety, while others are forced to move between temporary accommodation and damaged homes as they await assistance.

The government has pointed to the Defective Concrete Blocks Grant Scheme as the main mechanism for addressing the crisis. The Department of Housing said the scheme is designed to help homeowners remediate or rebuild affected homes and acknowledged the scale of the problem.

According to the department, changes being introduced through a new bill are “designed to improve supports” for affected homeowners, with the aim of speeding up applications, expanding eligibility and addressing concerns raised by campaigners.

However, many families argue that progress on the ground remains slow and that financial and bureaucratic hurdles continue to delay rebuilding efforts. As another Christmas approaches, they say the promise of reform offers little immediate comfort while they remain trapped in homes that are deteriorating day by day.

Campaign groups have renewed calls for faster intervention and more comprehensive support, warning that without urgent action, thousands of families will continue to endure unsafe living conditions well into the new year.
