A Typical Scenario: Ground-Floor Tenants Wake Up to Water in Their Rooms

This section is an illustrative example based on common post-flood situations. It is not a statement from a real person.

Auntie Daeng owns a three-storey rental building on a main road in Pathum Thani. The ground floor has a long row of rooms, mostly rented by factory workers on shifts, and some rooms have small children. In front there is a small grocery stall and motorbike parking.

It rained hard all night. The roadside drains could not cope, water rose over the road and flowed into the ground-floor rooms before dawn. Tenants woke to standing water, floating shoes, soaked mattresses lying on the floor and a sewage smell coming up through bathroom drains.

When the water fell, tenants asked in the building's LINE group what to do with their rooms, who would cover ruined mattresses and when the rooms would be safe for children. Auntie Daeng worried that if this was handled badly, tenants would move out and empty rooms with a musty smell or mould stains would be hard to let.

The solution was a step-by-step plan. Tenants moved usable belongings out and discarded damaged items. The landlord washed rooms and corridors and dealt with the drains, then booked rental room and apartment disinfection for the whole ground floor in one round before tenants moved back in.

Lat Lum Kaeo Rental Room Flood 2026: What the News Reported

This section summarises news reports. Conditions may change, so please also follow the latest notices from the local administration, Lat Lum Kaeo district and Pathum Thani province.

• According to Siam Rath, on 25 September 2026 heavy rain fell all night on Pathum-Lat Lum Kaeo Road, Moo 6, Khu Bang Luang subdistrict, Lat Lum Kaeo district, Pathum Thani.
• Water flooded rental rooms, which the report said were 30 ground-floor rooms, along with shops and houses in the same area.
• The cause given was roadside drains blocked with soil, sand and stones, so water could not drain away fast enough.

The source did not state the depth of water inside the rooms, so this article does not give a figure and does not refer to any particular building. Landlords and tenants should judge from the water line in their own rooms.

Nationally, Daily News reported data from the Department of Disaster Prevention and Mitigation (DDPM) at 06.00 on 5 October 2026: 26 provinces plus Bangkok affected, totalling 1,270,151 households. Many rental buildings in several provinces face the same problem.

A blocked-drain cause matters for recovery. Water that overflows from drains usually carries sediment and wastewater from the pipes, and if the blockage is not fixed, the next heavy rain can flood the rooms again. Clearing drains, or asking the local authority for help, should happen alongside washing and spraying.

Why Lat Lum Kaeo Rentals Need Rental Room and Apartment Disinfection After Floods

First, water overflowing from roadside drains is not clean rain. It has passed through pipes carrying wastewater from homes and shops. The World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) advise treating every surface touched by floodwater as contaminated, cleaning it first and then disinfecting.

Second, a rental room is small and used for everything: sleeping, cooking, drying clothes and storage. Flooded surfaces are the surfaces tenants live on all day, especially those who sleep on mattresses placed directly on the floor.

Third, rental buildings have shared spaces such as corridors, stairs, rails, entrance doors, mailboxes and laundry corners, so germs move easily from one room to another.

Fourth, rental rooms are often closed up with few windows and poor airflow. When walls and floors absorb moisture, mould grows faster than in an airy house. Musty smells cling and are a leading reason rooms cannot be let.

Finally, tenant confidence. Tenants who see the landlord acting seriously tend to stay. Those who feel the room is still unsafe tend to leave, which means lost income for the landlord.

Hotspots in Rental Rooms and Apartments to Check Before Spraying

Inside each room

• Floors and skirting, especially corners and under the bed where sediment collects.
• En-suite bathrooms and floor drains, where sewage backs up most easily.
• Cooking corners: sinks, shelves and small fridges left without power. Throw away food touched by floodwater.
• Mattresses, pillows and curtains. Soaked soft items are hard to clean properly; consider discarding them.
• Wardrobes and particleboard furniture, which swell easily and harbour mould.
• Lower walls and door frames. Look for water lines, blistered paint and mould spots.

Shared areas of the building

• Ground-floor corridors and stairs, rails and floors everyone uses.
• Entrance doors, mailboxes and doorbells, the most-touched surfaces.
• Laundry corners and shared toilets, if any, which need extra washing.
• Motorbike parking and the building front, the route mud takes inside.
• Drains around the building and rubbish points, the cause of flooding and a food source for rats.

Landlords and tenants should photograph each room before washing, to agree on property damage, support insurance claims and plan with the technicians.

The Germs Floodwater Brings Into Rental Rooms

This is general information and does not replace medical advice.

Sewage bacteria such as E. coli (Escherichia coli) and coliforms come from wastewater in the drains and cling to sediment on floors and walls. Swallowed, they can cause diarrhoea and stomach pain.

Salmonella causes food poisoning with fever, diarrhoea and cramps, so flooded cooking corners need careful washing.

Leptospira, the cause of leptospirosis, is shed in the urine of rats that often live around drains and bins. It enters through cuts or the eyes and mouth. Typical signs are sudden high fever, headache and calf pain.

Gut viruses and viruses affecting children. Norovirus and rotavirus cause sudden vomiting and diarrhoea, while hand, foot and mouth disease virus and RSV spread through hands and surfaces children touch. Buildings with many families living close together can see quick spread.

Mould and spores grow on wet walls, particleboard, mattresses and fabric. The CDC advises cleaning and drying within 24 to 48 hours. Spores can trigger allergies and asthma.

According to WHD's service and product information, CHEMGENE HLD4H is stated to cover many viruses, bacteria and fungi. Organisms named on the website include COVID-19, RSV, influenza H1N1 and H5N1, hand, foot and mouth disease virus, norovirus, Salmonella and fungi. Organisms not named, such as E. coli, Leptospira and rotavirus, belong to the bacteria or virus groups the product says it covers. For test data on a specific organism, please ask WHD directly.

Who in a Rental Building Is Most at Risk, and When to See a Doctor

• Young children crawl and play on floors and put their hands in their mouths.
• Older people and pregnant women should avoid heavy mud clearing.
• People with chronic illness such as diabetes, kidney or lung disease, asthma or weakened immunity.
• Shift workers, often tired and short of sleep, who go straight back to their rooms after work.
• Anyone cleaning rooms and corridors, in direct contact with water and mud; cuts raise the risk.

See a doctor promptly for sudden high fever, headache, severe calf pain, red eyes, reduced or dark urine, severe diarrhoea, persistent vomiting, breathlessness, a child with fever plus mouth sores or spots on hands and feet, or a wound that is red, hot and swollen. Tell the doctor you were exposed to floodwater. Spraying looks after spaces; it does not replace medical care.

What Happens If Rental Rooms Are Not Restored Properly

Tenant health. Tenants who move back too early may get diarrhoea, rashes, allergy flare-ups or rat-borne infections, and when several rooms fall ill, worry spreads through the whole building.

Landlord income. Rooms that smell musty or show mould are hard to let. Existing tenants may ask to leave, and prospective tenants notice the smell immediately.

Property. Particleboard furniture, walls and door frames left damp deteriorate further, and repairs cost more than early action.

Relationships. Without clear agreement on who handles what, disputes can arise over damage and rent for the days rooms cannot be used.

Why Mopping a Rental Room the Usual Way Is Not Enough

• Mopping with plain water removes visible dirt but does not disinfect, and sediment remains in tile grout and along skirting.
• Bleach without washing first works poorly on muddy floors, and in a small, poorly ventilated room fumes can irritate. Mixed with other cleaners it can release dangerous gases; the CDC warns never to mix bleach with ammonia or other cleaners.
• Closing the room to dry traps moisture, and mould appears within days.
• Air freshener only masks the smell.
• Painting over water stains on a damp wall leads to peeling and returning mould.
• Every room doing its own thing. Different methods and products give uneven results, and shared areas are often forgotten.

What works is a clear sequence: remove mud, wash with clean water and detergent, dry, then spray every flooded room and the shared areas in the same round. Spraying is the final step after washing. It never replaces it.

Service steps for rental rooms and apartments

1. The landlord or building manager gets in touch. Call 065-556-6294 or LINE @whd268 with the location, number of flooded rooms, approximate room size, shared areas and photos.
2. Survey and planning. The team assesses the site, lists each room and shared area, and explains what to prepare.
3. Mud removal and washing first. Tenants remove usable belongings and discard damaged items; the landlord washes rooms, corridors and bathrooms with detergent and ventilates to dry.
4. Prepare rooms on spray day. Put away food, dishes, toothbrushes and children's toys. Tenants and pets leave rooms and corridors being sprayed.
5. Technicians spray room by room, then corridors, stairs and laundry corners.
6. Wait before re-entry. According to the service information, usually about 30 minutes. Follow the time technicians give on the day.
7. Ventilate, then rinse food-contact surfaces and toys with clean water before use.

We do not claim spraying leaves no residue at all, so please follow the technicians' advice on ventilation and rinsing. According to the service information, customers receive a free CHEMGENE spray bottle and WELLGIENIC wet wipes under the current promotion, and a tax invoice is available. For rooms that still smell musty, the ozone disinfection service is a complementary option, carried out with no people or pets inside.

How Is the Price for Rental Room Disinfection Set?

Many landlords ask about price first. We do not publish a single price in this article, because the cost depends on several factors:

• Area and number of rooms: how many rooms flooded and the size of corridors and shared areas.
• Site condition: rooms already washed, dried and ready take less time than rooms still being prepared.
• Disinfectant volume and method: spraying, ULV fogging or a combination, depending on the space.
• Distance and travel from the Bang Khae office to Lat Lum Kaeo or elsewhere in Pathum Thani.

The team quotes after a site survey or after reviewing photos. Call 065-556-6294 or LINE @whd268. Landlords with several flooded rooms should book them all in the same round so the work is planned efficiently and tenants can move back at the same time.

Before and After Rental Room Spraying: What Tenants Will Notice

If the blocked drain in front of the building is not cleared, or wet materials remain in rooms, problems may return, so fix the cause at the same time.

Example Case: A Three-Storey Roadside Rental Building in Pathum Thani

This example case is based on common situations to explain the workflow. It is not a real customer review.

Auntie Daeng told tenants in the LINE group that the ground floor would be restored over three days. On day one, tenants moved usable belongings upstairs or into an empty room, photographed damage and discarded mattresses and food that had touched floodwater. She hired workers to clear the drain in front of the building and reported the roadside drain to the local administration.

On day two, cleaners washed floors, bathrooms and the corridor with detergent, opened every door and window, and ran fans. On day three, WHD technicians sprayed room by room, then the corridor and laundry corner, while tenants waited upstairs and outside. After the stated time, tenants opened windows, rinsed dish racks with clean water and moved their things back. Auntie Daeng kept the job sheet and used before and after photos to answer questions from new tenants viewing rooms.
