Closing a villa for winter in Mallorca: the end-of-season checklist

How to close a Mallorca villa after summer: water, pool, damp, garden, security and the winter check visits that prevent expensive damage.

September and October are the months when half of south-west Mallorca shuts the house up until the following spring, and the difference between doing it to a protocol and doing it in a hurry shows up precisely eight months later, on reopening. A closed villa is not on pause: it is still exposed to high relative humidity, to easterly storms with horizontal rain and salt, to power cuts, to leaks nobody hears, and to a garden that keeps growing or drying out depending on how the irrigation was left. Most of the expensive incidents we see in seasonal properties — a leak in a guest bathroom soaking a partition wall for weeks, a tripped consumer unit that leaves the pool filtration dead, mould in wardrobes and mattresses, a blocked terrace drain that eventually pushes water into the living room — do not happen through bad luck. They happen because nobody defined what gets shut down, what stays running, and who comes to check it.

The critical block is the building services. On water, the sensible approach is to close the main stopcock if the house is genuinely empty, drain circuits that could stay pressurised, and isolate the bathrooms that will not be used, leaving only what is strictly necessary live; it is also worth checking tap hoses and flexible connectors, which are the most common failure point, and draining or correctly programming the softener and osmosis unit so they are not left with stagnant water for months. On electricity, the opposite applies: you do not switch everything off. You have to decide which circuits stay alive — alarm, cameras, router, dehumidifiers, pool pump, freezer if it stays in use — and disconnect the rest to avoid phantom loads and surge damage during storms; a surge protector and a power-cut alert to the manager's phone are worth far more than they cost. On climate systems, clean the filters and service the units before shutting down, leave them off but accessible, and where the system allows it, programme a low-temperature maintenance mode for winter. Gas, if there is any, gets shut off at the bottle or tank valve.

The second block is damp and interior preservation, which in Mallorca causes the most silent damage. A closed house with the blinds down, no ventilation and cold stone inside will condense; the result is black spotting on the north-facing walls, textiles that smell shut in, and timber furniture that opens up at the joints. The effective measures are simple: leave wardrobes and internal doors ajar so air circulates, remove or protect textiles and mattresses with breathable covers — never sealed plastic — empty and prop open the fridge and dishwasher, top up or cap the traps so smells do not rise, and place dehumidifiers with permanent drainage or, at minimum, moisture absorbers in the worst rooms. Outside, cushions, parasols and terrace textiles come in, timber and natural-fibre furniture is protected, every drain and gutter is cleared and tested before the first storm, and awnings and pergola fabrics are checked so nothing is left extended at the mercy of the wind. In the garden it is time to reprogramme irrigation to a winter regime rather than switch it off entirely — young Mediterranean planting still needs occasional water — carry out the relevant pruning, and leave the pool in winter mode with the right level, chemical balance and filtration hours, with or without a cover depending on the case.

The third block, and the one that genuinely makes the difference, is supervision while the house is empty. Closing it properly is half the job; the other half is somebody coming round at a defined frequency — fortnightly or monthly depending on the property and its risk profile — with a real checklist: inspecting for damp and ceiling stains, opening and airing the house, checking for leaks and reading the water meter, testing the alarm and cameras, checking the pool and garden, collecting post, and confirming nothing outside has come loose after a storm. On top of that sits a security layer: an alarm connected to a monitoring centre, simulated occupancy through programmed lighting, confirmation that the insurance policy expressly covers unoccupied periods — many policies require periodic visits or impose limits owners discover too late — and a local keyholder able to respond the same day when something goes wrong. That is exactly the job of a property management service in Mallorca: not just closing the villa in October, but documenting its condition with photographs, handling whatever winter throws at it, and handing it back in March ready to use, with the pool running, the garden recovered and the house aired, so the owner does not spend the first two days of their holiday fixing what broke in January.
