Coming home to Kerala after years abroad, and wondering what state your house is in?

The safe answer: do not walk in on arrival day and start cleaning. Ask someone you trust to inspect the house 3–4 weeks before you land. Check electricity, gas, and water first. Then book a deep clean 7–10 days before arrival, so the house gets time to air and dry.

This cleaning checklist for NRI home Kerala follows the same order a professional team uses. It also works for cleaning your house after returning to Kerala, or for any house cleaning after a long absence. Share it with your caretaker, a relative, or your cleaning company.

Why a Closed House in Kerala Needs More Than a Normal Clean

A house that stays shut for months behaves very differently from one where people live. Kerala’s weather makes the problem bigger.

Kerala gets rain in two spells: the southwest monsoon from June, and the northeast monsoon from October to December. Humidity stays high for most of the year. When nobody opens the windows, that moisture gets trapped inside. Mould, musty smell, termites, and rats follow.

Many Kerala families know this situation well. The Kerala Migration Survey 2023, by IIMAD and the Gulati Institute of Finance and Taxation, estimated about 2.2 million emigrants from Kerala, and about 1.8 million emigrants who had returned home. Malappuram alone was the origin of nearly 3.8 lakh emigrants that year.

Damp is also a health matter. The WHO Guidelines for Indoor Air Quality: Dampness and Mould (2009) conclude that people living in damp or mouldy buildings face a higher risk of respiratory symptoms, respiratory infections, and asthma flare-ups. If you are returning with children or elderly parents, this matters even more.

How a closed house cleaning checklist differs from a regular deep clean

When to Start: A 4-Week Timeline for House Cleaning Before NRI Returns

Good timing saves money and stress. Clean too early and dust settles back. Clean too late and the floors and walls have no time to dry.

Step 1: Safety Checks Before Anyone Starts Cleaning

Some problems in a closed house can hurt people, not just spoil the look. Check these first.

Electricity

Rats chew wires, and damp switchboards can short-circuit. Ask a licensed electrician to inspect the main board, switches, and earthing before you switch on the power. Test that the earth-leakage breaker (ELCB or RCCB) trips when you press the test button. Do not switch on the main in a damp house without this check.

LPG gas

If the cylinder stayed connected, inspect the rubber tube and regulator for cracks. Brush soapy water on the joints. Bubbles mean a leak. Never use a flame to test. If you smell gas, open windows, avoid switches, and call your gas distributor.

Snakes and other visitors

A closed house with a leafy compound can attract snakes, wasps, and bats. Check the sit-out, shoe racks, gaps near doors, and the roof edges. If you spot a snake, do not try to catch it. The Kerala Forest Department’s SARPA app connects you with trained snake rescuers near you.

Roof and walls

Look for ceiling stains, cracked roof tiles, and blocked gutters. Fix leaks before cleaning. Otherwise you will clean twice.

Step 2: Clean the Water Tanks, Pipes, and Drains

Most people forget this step, but it decides whether your first shower is pleasant or not.

Overhead tank and sump: Drain, scrub, rinse, and refill. Stagnant water collects sludge and breeds insects. Close the lids tightly afterwards.
Taps and flush tanks: Run every tap and flush for a few minutes until the water runs clear.
Geyser: Drain it and refill it before the first use.
Floor drains and basins: Pour a bucket of water into each one. Dry drain traps let sewer smell and insects into the house.
Well water: Test it before drinking. Boil water until the result comes back.
Water purifier: Service it and change the filters.

Step 3: Room-by-Room Cleaning Checklist for an Empty House in Kerala

Work from top to bottom and from dry to wet. Dust falls downwards, so floors always come last.

Kitchen

Throw away old food, spices, and oil. Check for cockroaches, ants, and rat droppings.
Wash shelves and cupboards inside and out. Wash all utensils again, even if they were stored clean.
Degrease the chimney, stove, and burners.
Clean the fridge with warm water and baking soda. Leave the door open to dry before you switch it on.
Check rubber gaskets on pressure cookers and the fridge door seal for mould.

Bathrooms

Scrub black grout and mouldy corners.
Descale taps and showers. Replace dried-out hoses.
Check flush tanks and pipe joints for leaks.
Clean exhaust fans, which collect a lot of dust and damp.

Bedrooms

Dry mattresses in sunlight if possible. Check for mould spots and musty smell. Replace old pillows that smell.
Wash bed linen and curtains.
Empty the wardrobes, wipe them, and air them. Look for silverfish, termites, and mildew on clothes, bags, and shoes.
Keep moisture-absorber packets inside after cleaning.

Living room, AC, and electronics

Dust fans, lights, and high shelves first. Then wipe walls, windows, and grills.
Vacuum sofas and check the fabric for mould. Kerala’s humidity makes sofas hold moisture for long (see our guide on sofa cleaning in Kochi).
Service the AC before first use. Filters and coils can grow mould in a closed house.
Switch on TVs and other electronics one by one, after the power check.

Pooja room

Clean the nilavilakku, brass lamps, and idols. Wipe the wooden shelves and replace old wicks and oil.

Sit-out, compound, and outside

Sweep leaf litter and trim branches that touch the roof.
Remove coconut shells, pots, and containers that hold rainwater. These breed mosquitoes.
Clean gutters and check that outside drains flow freely.
Test gate locks and the compound wall.

Step 4: Check for Termites, Rats, and Mould

Pests grow quietly in a closed house. By the time you see them, they have already settled in.

Termite signs: Thin mud tubes on walls and door frames, hollow-sounding wood, and fine wood dust.
Rat signs: Droppings, chewed wires, and shredded paper or cloth.
Mould signs: Black or green patches on walls, peeling paint, and a musty smell.

Wipe small mould patches with a mild detergent solution and dry the wall fully. If patches are large or keep coming back, find the moisture source first. Do not paint over mould or termite damage. Treat it, then paint. For termites and rats, use a professional pest control and disinfection service.

How Smart Zero Handles Closed-House Cleaning in Ernakulam, Kottayam, Thrissur, and Malappuram

If you live abroad, you cannot supervise the work yourself. A reliable cleaning partner solves that.

Smart Zero is a Kochi-based facility management company, a division of SZERO Solutions and Services LLP. The team cleans homes, villas, and flats, and also offers deep cleaning, furniture and carpet cleaning, glass cleaning, and disinfection and pest control. We serve Ernakulam, Kottayam, Thrissur, Malappuram, and other districts of Kerala.

What you can ask for before you return:

A site visit and a quote based on your house size and its condition
Deep cleaning of every room, kitchen, and bathroom
Sofa, mattress, and furniture cleaning
Disinfection and pest control
Cleaning planned around your arrival date

For a home deep clean, Smart Zero’s usual time is 4–8 hours, depending on size and condition. A house that has been closed for a long time may need more. A site visit gives the right estimate.

To book from abroad, keep these ready: your arrival date, the house type and size (for example, a 3BHK flat or a 4-bedroom villa), who will hand over the keys, and photos of problem areas.

If your home will stay empty again, ask about regular visits. Smart Zero also works with its partner R2S Property Management for property and asset maintenance.

Frequently Asked Questions

1. How do I clean my house in Kerala before returning from abroad?

Start with a local inspection and safety checks for electricity, gas, and water. Then air the house, clean the water tanks, and deep clean from top to bottom. Treat pests and mould, and finish with a walk-through before you arrive.

2. How early should I book cleaning before I return?

Book 3–4 weeks ahead. Schedule the deep clean 7–10 days before you land, so floors and walls dry and the house airs well.

3. How do I remove musty smell from a closed house?

Open all doors and windows for a day or two. Wipe walls and floors with a mild detergent, dry them fully, and wash curtains and bedding. Find and fix leaks. If the smell stays, call professionals.

4. Can I arrange house cleaning in Kerala from abroad?

Yes. Share your arrival date, house details, and photos with a cleaning company, and tell them who holds the keys. Smart Zero takes bookings by phone and WhatsApp.

5. How much does NRI house cleaning cost in Kerala?

The cost depends on house size, how long it stayed closed, and the services you add, such as pest control or sofa cleaning. A site visit gives an accurate quote.

6. Is it safe to switch on the power in a house closed for a long time?

Not before a check. Damp switchboards and rat-chewed wires are real risks. Ask a licensed electrician to inspect the main board and test the earth-leakage breaker first.

7. How do I protect my empty house from termites and pests?

Look for mud tubes, wood dust, and droppings. Keep the compound clean and the house ventilated. Use a professional pest control team for treatment, especially for termites.

8. How often should an empty house in Kerala be cleaned?

For a lived-in home, Smart Zero suggests deep cleaning every 3–6 months. For a closed house, ask someone to visit every few months to air the rooms, flush the taps, and dust. Do a full deep clean before you return.

Conclusion

A closed house in Kerala needs a plan, not a quick sweep. Check safety first, clean the water system, deep clean room by room, and treat pests and damp. Then walk through the house before the family arrives.
