Donegal is home to thousands of holiday homes. From Downings to Dunfanaghy, Rathmullan to Rossnowlagh, whole stretches of our coastline fill up every summer and quieten down again come September. And every autumn, as the last cars head back down the road, thousands of properties are locked up and left to sit empty for months at a time. 

For a hidden leak, that is the perfect scenario. No one to hear the drip. No one to spot the damp patch. No one to notice the water pressure fading. Just month after month of quiet, uninterrupted damage. 

Why empty properties are at the highest risk 

In an occupied house, most leaks get caught early. Someone notices the stain on the ceiling, the musty smell in the hall, or the bill that does not add up. The damage is annoying, but it is usually contained. 

In an empty house, a leak can run from October to Easter without a single person laying eyes on it. By the time the owner arrives for the first weekend of the season, a small weep from a pipe joint has had six months to soak into floors, walls, and timbers. What would have been a minor repair in an occupied home becomes rotten joists, ruined plaster, and a serious mould problem in an empty one. 

Water damage is bad enough when it is caught in days. Caught in months, it can run to tens of thousands of euro. 

The most expensive leaks we see in Donegal are almost never the dramatic burst pipes. They are the slow, silent ones in properties where nobody was around to notice. 

The end-of-season danger zone 

The weeks after a busy summer are actually when holiday homes are most vulnerable. The plumbing has just been through months of heavy use, with showers running, washing machines going, and outside taps in constant service. Joints, fittings, and seals have been worked hard, and any weakness that has developed over the summer is about to be left completely unsupervised. 

Then winter arrives. Donegal frost gets into pipes in attics, garages, and external walls, and freeze-thaw cycles do the rest. An empty, unheated house is far more likely to suffer frozen and cracked pipes than a lived-in one, and far less likely to have anyone there when the thaw turns a crack into a flow. 

Your end-of-season checklist 

Before you lock up for the winter, a small bit of effort can save an enormous amount of heartache: 

  • Know where your stop valve is, and consider turning off the water supply entirely while the property is empty 
  • If the heating system needs water left on, set it to come on regularly at a low level to keep frost at bay 
  • Check under sinks, around the cylinder, behind the washing machine, and at visible pipework for any signs of weeping or staining 
  • Take a water meter reading when you leave, and check it again on your next visit. If it has moved while the house was empty, water has been going somewhere 
  • Ask a neighbour or local keyholder to walk through the property every few weeks, especially after cold snaps 
  • Deal with any niggles now, not next June. A dripping overflow or a suspect patch of damp will not improve over the winter 

A word on insurance 

Many home insurance policies include unoccupancy conditions, which change or restrict your cover once a property has been empty for a set period, often 30 or 60 days. Some require the water to be turned off, or the heating to be maintained, for cover to stay valid. If your holiday home sits empty over the winter, it is well worth checking exactly what your policy requires of you, because a leak claim in an unoccupied property will be looked at closely. 

A professionally documented leak detection survey also carries real weight here, showing that the problem was identified and dealt with properly the moment it was suspected. 

Book a pre-winter leak check for your holiday home 

If you own a holiday home or rental property anywhere in Donegal, an end-of-season check is one of the smartest things you can do before locking up. AMG Leak Detection uses acoustic listening equipment, thermal imaging, and tracer gas to confirm whether your plumbing is sound, all without lifting a floorboard or opening a wall. 

It is a small job in September. It could be a very big job in April.
