Closing up the beach house after summer: a cleaning checklist for Rota and Costa Ballena

September in Rota, Costa Ballena or Chipiona has a familiar look: the streets empty, the beach bars pack up and thousands of families head back to Jerez, Seville or Madrid after spending the summer in their beach house. Before locking the door, there’s one job many people rush and leave half done: closing the house properly.

A house by the sea that stays shut from October to May suffers more than any other home. Salt keeps getting in through the gaps, winter damp builds up with no ventilation, and any leftover food or standing water turns into a problem. Whatever doesn’t get cleaned in September usually shows up in March as mould, rust, bad smells or insects.

In this guide we share the checklist we follow when we close holiday homes on the north-west coast of Cádiz, in an order that makes sure nothing is forgotten.

Why closing the shutters isn’t enough

The temptation is to tidy up the basics, lower the shutters and leave. The trouble is that three things keep working while the house is empty:

• Damp. In winter, relative humidity on the coast easily goes above 70 %. With no ventilation, it condenses on cold walls, in wardrobes and in mattresses.
• Sea salt. Sea air leaves salt on glass, window tracks, fittings and appliances. Over time it rusts metal and leaves stubborn marks.
• Sand and leftovers from the summer. Sand in sofas, rugs and corners holds moisture, and any crumbs in the pantry attract ants and cockroaches.

A good closing clean doesn’t just prevent problems: it means your first visit in spring is about opening up, airing the house and enjoying it, rather than spending the weekend cleaning.

Kitchen checklist: fridge, pantry and appliances

The kitchen is the room that causes the most problems if it’s closed badly.

1. Empty the fridge and freezer. Leave nothing behind, not even drinks or sealed sauces. Unplug, let the freezer defrost onto towels and clean everything with warm water and bicarbonate of soda.
2. Leave the fridge door ajar. A peg, a wedge or a folded cloth will do. Closed and switched off, it fills with mould within weeks.
3. Check the pantry. Take or throw away flour, rice, pasta, biscuits and anything that’s been opened. Clean the shelves and store whatever stays in airtight jars.
4. Clean the oven, hob and extractor hood. Grease left in the hood filter goes rancid and attracts insects.
5. Empty and clean the dishwasher, leave the door ajar and wipe the rubber seal.
6. Drains. Pour hot water with a little vinegar down the sink and a glass of water into every floor drain so the traps don’t dry out and let smells up.
7. Take out all the rubbish, including the recycling, and wash the bins.

Bathrooms, water and utilities

• Deep clean the toilets, shower screen and tiles, and dry everything. Limescale and water left in September become mould by November.
• Pour a little water into the toilet and close the lid so the trap doesn’t dry out.
• Turn off the main water stopcock. A small leak in an empty house over several months can end in a flood and trouble with the neighbours.
• Electric water heater: switch it off if the house will be closed all winter.
• Electricity: leave only the essentials connected, such as an alarm, a dehumidifier or the router if you have cameras, and unplug everything else.
• Gas: turn off the valve on the bottle or the supply.

Linen, mattresses and wardrobes

Bedding and towels put away even slightly damp come out in spring stained and smelling musty.

• Wash all the bedding, towels, light curtains and covers before you leave, and only put them away when they’re completely dry.
• Store them in fabric bags or lidded boxes, not sealed plastic bags, which trap moisture.
• Air the mattresses: strip the sheets, let them breathe for a few hours and stand them upright or use a breathable protector. If they’ve collected sand or summer stains, this is the best moment for an in-home mattress clean.
• Put moisture absorbers in every wardrobe and leave the doors slightly open.
• Vacuum sofas and rugs to get rid of the sand. If you can, roll up the rugs and store them off the floor.

Terrace, pool and outdoor furniture

The terrace is what the Levante wind punishes most over the winter.

• Clean and dry the outdoor furniture before storing it. If it won’t fit inside, group it against a wall and cover it with breathable, well-secured covers.
• Put away cushions, awnings and parasols clean and dry. An awning rolled up wet fills with mould within weeks.
• Sweep the sand off the terrace and clean the tracks of the sliding doors. We explain how in our guide to protecting your home from sea salt and the Levante wind.
• Empty plant-pot saucers so there’s no standing water or mosquitoes.
• Pool, if you have one: winterise it with the right product and a cover. This is usually handled by the community’s maintenance team or a pool company.

Protection against damp and salt

• Cover the furniture with old cotton sheets, not plastic, so it can breathe.
• Leave interior doors open and wardrobes slightly open so the air circulates.
• Shutters: lower them, but not all the way if possible. A few centimetres of light reduce condensation and help you spot if anyone has got in.
• Dehumidifier: if the house has damp problems, one with continuous drainage into the sink or shower tray can run all winter without emptying the tank.
• Metal fittings: a wipe with a cloth barely moistened with oil protects hinges, locks and handles from rust.

The day before you leave

A final, orderly check avoids surprises:

1. Sweep and mop all the floors, working from the back of the house towards the door.
2. Clean the windows on the inside so the salt doesn’t sit on them for months.
3. Check that windows, sliding doors and skylights are firmly closed.
4. Make sure there’s no food, rubbish or water left in any container.
5. Take photos of every room. They’ll help you check the state of the house when you return and, if you rent it out, serve as a record.
6. Leave a set of keys with someone you trust or with your maintenance service.

What if you run out of time?

Closing a house properly takes a whole morning, and many owners are already back home by the time they remember what they didn’t do. At Hola Limpio we handle the full closing of holiday homes in Rota and Costa Ballena, El Puerto de Santa María and along the rest of the coast: a deep clean, the fridge, linen, the terrace and furniture protection, with photos of the result so you can see it from home.

If you’re going to rent it out in spring, we can also get it ready for the first guests with our holiday rental cleaning service and our turnover checklist. Get in touch and we’ll prepare a free, no-obligation quote.
