What actually happens to a closed home in Thailand
Six months of shut windows in a tropical climate is not a neutral state. Here is what happens, month by month — and what prevents it.
Free for owners. Our partners pay us — you pay their normal rate.
A house shut for six months in a tropical climate does not simply wait for you. It changes. Slowly at first, then in ways that cost real money.
This is what actually happens, month by month — and, more usefully, what separates the owners who arrive to a house that is ready from the ones who arrive to a list of problems.
The first month — what is already happening
Nothing looks wrong yet. That is the problem. Humidity in Hua Hin sits high year-round, and a closed house traps it. Within weeks:
- Wardrobes and drawers begin to hold damp — the first place it shows, and the last place owners check
- Rubber seals on taps, windows and shower doors start to dry and harden
- Pool water begins to lose its balance; without circulation, algae has its opening
- Ants, geckos and the occasional rodent move in, attracted by stillness and warmth
None of this is dramatic. All of it is cheaper to stop in month one than to fix in month six.
Month three — the problems that start costing money
By now the small things have had time to become real ones:
- Mould has taken hold behind furniture and along exterior walls, not just in wardrobes
- A hardened seal fails — a slow drip under a sink that nobody sees for three months
- The pool is green, and the pump has been sitting unused long enough to be uncertain
- A small roof leak has had weeks to spread into ceiling plaster and timber
- Air conditioning units that never run develop problems that only appear when you switch them on
The economics of month three: an airing visit and a pool service cost a fraction of
re-plastering a ceiling, replacing a pump, or replacing a wardrobe that has gone soft with damp.
Month six — what owners find when they arrive
This is the part that is not really about money. Owners who arrive after six closed months describe the same sequence: the smell first, then the list.
And then the real cost appears — not the repair bill, but the holiday. Three weeks of leave spent supervising a contractor you have never met, in a language you do not speak, paying whatever he quotes, because you have no baseline and no time to get a second opinion.
"It is not the cost of the repair that hurts. It is arriving for three weeks of holiday and spending them managing a building site."
What prevents this — a schedule, not heroics
Nothing here requires a clever solution. It requires someone to actually turn up, on a schedule, and work through a list:
| How often | What should happen |
|---|---|
| Every visit | Windows and doors opened, rooms aired, a walk of the whole property inside and out |
| Every visit | Water under sinks checked, ceilings and walls checked for new marks |
| Weekly | Pool chemistry, filters and pumps run; water level maintained |
| Fortnightly | Garden kept down; palms and hedges trimmed; irrigation checked |
| Monthly | Air conditioning run briefly; appliances and pumps tested; meter readings taken |
| Monthly | Bills paid and reconciled — you see what was actually spent |
| Every visit | A dated photo report, and an honest note about anything that needs attention |
| Before you arrive | House opened and aired, systems tested, fridge stocked if you want it |
What it costs to fix versus to prevent
We are not going to invent numbers for you — the range is too wide to be honest about. But the shape of the comparison is consistent:
- Prevention is a routine monthly cost, predictable, billed the same each month
- Repair is irregular, urgent, and priced by whoever is standing in front of you when it is discovered
- Prevention is almost always cheaper per year — but it is invisible, which is why owners skip it
The category of cost that kills owners is not the monthly fee. It is the emergency that arrives with no baseline: a quote you cannot evaluate, for work you cannot inspect, on a deadline you did not choose.
Checklist: what your caretaker should do every single visit
- Open windows and doors; air every room
- Walk the exterior — roof line, gutters, walls, gates
- Check under sinks, around toilets, and below air conditioning units
- Look for new marks on ceilings and walls, inside and out
- Test the pool: chemistry, filter, pump, water level
- Check the garden for storm damage and overgrowth
- Run the air conditioning briefly; test taps and pumps
- Take meter readings
- Photograph anything notable — and send you the photos with a date
- Write a short note: what was done, what needs attention, what it will cost
If nothing happened, the report should say nothing happened.
Invented urgency is the fastest way to lose an owner's trust — and the fastest way for us to drop a partner.
Questions owners ask
Caretaking, answered honestly.
How often should someone visit a closed home in Thailand?
Weekly or fortnightly while it is closed, and monthly when it is in use. Pool and garden need attention at least weekly in the growing season — that is a separate arrangement from the property visits themselves.
Is it worth paying for caretaking if I only come once a year?
That is usually exactly when it matters most. Six to eleven months of a closed house in a tropical climate is the scenario caretaking exists for — the cost is routine, the repairs it prevents are not.
Can I just ask a neighbour to look in occasionally?
Neighbours are genuinely useful, and most owners have someone who keeps an eye out. But a favour does not include pool chemistry, a written photo report, or a contractor who can be called on a Saturday. Most owners end up with both.
How do I know the caretaker is not inventing work?
Insist on dated photographs of anything that needs attention, and a contractor's own invoice for any repair — not a summary. Ask for a spending limit: below it, small fixes are handled straight away; above it, you are asked first.
