Keeping a seaside rental in working order

Salt air and a heavy monsoon age a property faster than guests ever will. A short, fixed routine twice a year costs less than the repairs it prevents.

Owners inland replace fittings when they break. Near the sea that approach fails, because corrosion and damp attack everything at once and the failures arrive during the busiest weeks. The properties that stay bookable run to a calendar: a full inspection before the rains, a lighter one after them, and a weekly visit whenever the place is empty.

Before the monsoon

• Clear terrace outlets, gutters and yard drains, and pour water through them to check they actually run.
• Reseal window frames, door thresholds and any terrace waterproofing; look for hairline cracks where a parapet meets the slab.
• Service the pump and check that the electrical board, earthing and outdoor sockets are protected and dry.
• Cut back branches over the roof and secure anything on a terrace that wind can move.
• Test the generator or inverter under load, not by switching it on for a minute.

The empty-flat problem

A closed property near the sea grows mould within a fortnight in the wet season. Someone must open it, run the fans, air the cupboards and check for leaks every week. Store linen sealed and dry rather than folded in a damp wardrobe, and leave cupboard doors ajar between stays. If a smell has already set in, treat the cause and the surface, not the air: a deodoriser over live mould is a complaint waiting to be written.

Corrosion, and choosing fittings for it

Locks, hinges, window runners, railings, taps, air-conditioner units and outdoor lights all fail early near salt air. Where you can, choose fittings rated for coastal use, rinse exposed metalwork with fresh water, and keep spares for the parts that always go: a lock set, tap cartridges, a shower hose, light fittings. Air conditioners deserve a service before each season and a rinse of the outdoor unit; a unit that fails on a hot Saturday will cost you the booking and the review.

Water, in both directions

Know your source, your storage volume and how long a tanker takes to arrive, particularly if you advertise a pool. Then look at the other direction: where water leaves the property, and whether the septic arrangement copes with a full house. Both sides fail quietly until a full weekend arrives.

A storm kit, in the property

On exposed coasts, keep a charged light, drinking water, a basic first-aid box and printed emergency numbers in each unit, and tell guests where they are. Have a written policy for weather cancellations before the season starts. Guests forgive weather; they do not forgive being left to work it out alone.
