Advice written for a mountain chalet does not transfer cleanly to the Western Algarve. Most second homes here are not at risk of frozen pipework in the same way as a northern European house. They are at risk of being closed through the wetter, windier months with nobody looking at them.
Winter care is therefore less about “winterising” as a ritual, and more about humidity, rain, shutters, drainage and a visit schedule that matches how long the home stays shut.
The climate is mild. The house can still suffer.
Closed bathrooms, wardrobes and rooms with little air movement can develop musty air or surface mould indicators even when the days are bright. Coastal humidity does not take the winter off. A dehumidifier, a ventilation instruction or limited use of air conditioning may form part of an owner’s plan; none of those is a diagnosis, and equipment should be used according to its guidance.
Look for patterns rather than one reading. The longer explanation is in humidity and mould in Algarve holiday homes.
Rain shows whether terrace outlets, thresholds and obvious drainage paths are clear. Wind shows whether shutters and outdoor furniture were left able to take it. Those checks are visual and from safe ground. They are not a roof survey.
What not to copy from colder countries
Draining an entire water system, leaving heating on at a set frost temperature, or wrapping outdoor taps may be relevant in some buildings and irrelevant in others. The property’s own plumber, installer and insurer are the right people for that conversation. A home-watch visit should follow the written instruction, not invent a winter protocol from another climate.
The on-or-off decision for water and electricity remains property-specific. See should you leave electricity and water on.
Unsettled weather is the local winter theme
West-coast and clifftop homes take more wind and salt. After a significant period of rain or wind, a visual check can confirm that openings, shutters and accessible rooms appear unchanged, or it can flag a concern for a contractor. Inspection waits until access is safe. It is not guaranteed after every weather event. Read what to check after a storm and storm property checks.
Pools and gardens still need their specialists, or a written pause plus observation. Algae, debris and irrigation faults are easier to catch in winter if someone is still looking. See leaving a pool while you are away.
Vacancy is longer, so records matter more
A house closed from October to March is a different proposition from a house left for three weeks in June. Detection time grows. A slow leak has months, not days. That is why a baseline at closing and repeated reports through winter are more useful than a single “quick look” in January.
What happens to a villa empty for six months describes that stretch. Unoccupied property clauses is the place to start if your policy talks about vacancy; the wording comes from the insurer, not from a property-care company.
A winter routine
Close the house on purpose. Inspect on a schedule that matches the systems and exposure. After significant weather, request a check if conditions and access allow. Keep photographs. Do not wait for the Easter flight to discover a stain that started in November.
