Winter Mountain House Sitting: What You Really Need to Know

Leaving a second home in Savoie or Haute-Savoie vacant in winter presents a real risk. Frozen pipes, boiler breakdowns, snow infiltration, damage can happen quickly and be costly.

A guardian being present changes everything. Not just for pets, but for the house.

The Real Risks of a Vacant House in Winter

Frozen Pipes

Below -5°C, unprotected water pipes can freeze and burst. An undetected burst pipe for two weeks can lead to tens of thousands of euros in damages.

A present guardian immediately detects a drop in pressure, an abnormal noise, or a damp patch.

Boiler Insufficiently Set to Frost Protection Mode

Many owners set their boiler to "frost protection" before leaving. This is insufficient if temperatures drop below -10°C for several consecutive nights, or if the boiler breaks down. A guardian adjusts it, restarts it, and calls the heating engineer if necessary.

Weight of Snow on Structures

Roofs, skylights, awnings, exceptional snowfall can create structural problems. Clearing an entrance or monitoring a skylight that starts to leak is a 30-minute intervention that prevents a disaster.

Infiltration and Dampness

Freezing and thawing create cycles of infiltration in walls and roofs. A guardian who regularly checks all rooms detects these signs before they become serious.

Animals in Winter Mountains

Animals living at altitude have specific needs in winter.

Dogs:

Even cold-resistant breeds (Husky, Malamute, Pyrenean Shepherd) need a heated indoor space. Paws must be cleaned after walks on salted roads, as salt damages paw pads.

Shorter walks in extremely cold weather: -10°C with wind means a maximum 15-minute walk for most breeds.

Cats:

Never leave a cat outside at night below -5°C. Check potential hiding places (car engines, unheated outbuildings) before closing up for the night.
