Example case (a typical scenario drawn from common real-world situations, for illustration only; not a review from a specific customer)

A flooded car park near Lam Sali, and a children's playroom nobody dared to reopen

Pattra manages the juristic office of a twenty-something-storey condominium on Srinakarin Road, not far from Lam Sali junction. Most residents are young families who work in the city and commute on the Yellow Line monorail. On the night of 25 September, the rain did not stop until water on Srinakarin spilled down the ramp into the ground-level car park. Security staff stacked sandbags across the entrance, but water still seeped in and flooded the parking deck, the central rubbish room and the passenger lift lobby.

Two days later the water drained away. The housekeeping team hosed down the car park, pushed the mud into the drains and mopped the lobby with lemon-scented floor cleaner. Residents went back to using the lifts as normal, yet Pattra's phone buzzed almost hourly with messages in the condo LINE group. One resident said the car park smelled of drains and damp. Another asked when the third-floor playroom would reopen because her three-year-old was going stir-crazy. Several people posted photos of rats running past the rubbish room, and one mother said her child had just developed mouth sores after playing with friends in the building.

Pattra knew the hosing and mopping could not answer those questions. She needed a clear process, with someone accountable, a date and paperwork she could pass to the committee. That night she searched for "disinfection spraying Srinakarin".

Where Srinakarin Flooded: Lam Sali to Phatthanakan to Sukhumvit 77

The information below comes from a Thai PBS report on 29 September 2026 at about 13:19, based on Bangkok Metropolitan Administration flood data. Depths are water levels on the road surface at that time.

On Srinakarin Road

• Srinakarin Road, Lam Sali junction to Phatthanakan junction: listed as a flood point
• Srinakarin Road, Phatthanakan junction to Sukhumvit 77: listed as a flood point
• Srinakarin Road at Lam Sali junction: about 20 cm
• Srinakarin Road at the Kamphaeng Phet 7 junction: about 20 cm

Roads that cross or feed into Srinakarin

• Phatthanakan Road at the Srinakarin junction: about 24.7 cm, the highest reading on the list at the time; Phatthanakan Soi 53: about 20 cm, also reported as a high-water point by Dailynews
• Ramkhamhaeng Road from Rama 9 junction to Lam Sali, and from Lam Sali to Soi Ramkhamhaeng 129/4: flood points
• Krungthep Kreetha Road: flooded along its entire length
• On Nut Road, Soi 59: about 20 cm
• Seri Thai Road, Suan Siam to Seri Thai 71 junction, and Thetsaban Songkhro Road (flooded along its entire length), from the same list

The flood followed roughly 300 mm of rain in about 48 hours between 24 and 27 September 2026. The BMA declared all 50 districts a disaster zone on 26 September, and on 2 October 2026 the Department of Disaster Prevention and Mitigation reported about 329,000 Bangkok households affected.

This part of Srinakarin spans several districts, including Bang Kapi, Suan Luang and Prawet. It is defined by tall buildings with ground-level or basement car parks, housing estates set in lanes lower than the main road, and large commercial buildings with thousands of visitors a day. When the main road floods, water runs to the lowest point of each building and leaves sediment in places sunlight never reaches.

Post-Flood Germs Hiding in Srinakarin's Condos and High-Rises

High-rise buildings differ from detached houses: the water does not reach every unit, but it does flood the common areas everyone shares, such as car parks, rubbish rooms, lobbies, lift halls, plant rooms and sometimes gyms, playrooms or a ground-floor convenience store. Once these areas are contaminated, germs travel to every floor on shoes, pushchair wheels, suitcase wheels and lift buttons.

Hand, foot and mouth disease and RSV: the top worry for families with toddlers

Hand, foot and mouth disease is caused by enteroviruses and brings fever, sore throat, mouth ulcers and a rash or blisters on the hands and feet. It spreads through saliva, nasal secretions, faeces and contaminated surfaces. RSV is a respiratory virus that makes young children cough and breathe fast, and some cases need hospital care. Both are common in the rainy season anyway. After a flood, children tend to spend more time indoors or in shared spaces, so toys and playroom floors touched by many hands become hot spots. WHD's service information states its disinfectant covers both RSV and the hand, foot and mouth virus.

Norovirus and rotavirus in common areas

These viruses cause sudden diarrhoea and vomiting and spread very easily through hands and surfaces; only a small amount is needed to make someone ill. In a building where hundreds of households share lifts and handrails, one sick person and untreated touch points can lead to a cluster of cases.

E. coli and faecal bacteria in the car park

Ground-level car parks are often where water from street drains collects, and some buildings have sewage sumps or treatment tanks nearby, so floodwater may carry faecal contamination. Sediment that dries on floors, walls and pillars is kicked up by passing cars and carried on wheels and shoes up to the lobby.

Leptospirosis from rats in rubbish rooms and drains

Rats living in drains and rubbish rooms flee rising water into areas people use. Their urine may carry Leptospira, which enters the body through cuts or mucous membranes. Cleaners and guards who wade through the car park are directly at risk. Anyone with a high fever, headache and muscle pain, especially in the calves, within about two weeks of wading should see a doctor and mention the exposure.

Salmonella in ground-floor shops and cafés

Cafés, restaurants and minimarts on the ground floor of condos and commercial buildings face cross-contamination between floors and food. Salmonella causes food poisoning with diarrhoea, fever and stomach pain. All food and ingredients that touched floodwater must be discarded.

Mould in windowless rooms

Plant rooms, storerooms, rubbish rooms and lower car parks have little airflow and no sunlight, so dampness lingers. Mould can grow within a day or two on wet materials; the CDC recommends cleaning and drying within 24 to 48 hours. Spores can drift up lift shafts or ventilation, triggering symptoms in residents with allergies or asthma.

Who needs extra protection

Young children, pregnant women, older adults, people with chronic illness or weak immunity, and building staff who work in the car park and rubbish room. In a typical Srinakarin condo, that list covers a large share of the people using the lifts on any given morning: toddlers heading to daycare with a parent, retired residents who spend most of the day in the building, and the housekeeping and security teams who were the first to wade into the flooded car park. Contractors repairing pumps and electrical panels in the plant room should also be briefed, because they often work on their knees in places where sediment has settled. Simple measures such as boots, gloves, covering cuts and washing hands before eating protect these groups while the building moves through cleaning, drying and disinfection.

What Juristic Offices and Building Owners on Srinakarin Must Deal With

Residents' health: A child with hand, foot and mouth disease or several adults with diarrhoea at the same time quickly erodes trust in building management and may force more common areas to close.

Spiralling costs: Repeated in-house cleaning, disinfectants bought without a plan and repairs to materials that grew mould because they did not dry in time can add up to more than doing the job properly once.

Time and communication: The juristic office answers residents' questions every day. A clear spraying date and supporting documents make communication far easier.

Image and property value: A condo discussed online as smelling of sewage or having rats can affect rentals and resale for every owner in the building.

Families: Some parents move their children to relatives' homes temporarily because they do not trust the common areas, adding travel and cost.

Why Hosing Down the Car Park Is Not the End of the Job

Pressure washing: Great for pushing mud out, but it also sprays contaminated droplets onto pillars, walls and parked cars, and it does not disinfect on its own.

Mopping the lobby with scented cleaner: It looks and smells clean, but touch points such as lift buttons, handrails, glass doors and parcel lockers are usually not disinfected.

Bleach in enclosed rooms: The strong fumes in windowless rooms can sting staff's eyes and make breathing difficult, and bleach corrodes metal doors, drain grates and plant-room equipment.

Industrial fans: They reduce surface moisture, but if materials are already mouldy, the airflow spreads spores further.

Keeping the playroom closed indefinitely: Safe in the short term, but it does not solve anything; residents will keep asking when it will open and on what basis.

Cleaning yourself is still essential and always comes first. For large shared spaces, however, spraying by trained technicians reaches surfaces more evenly and gives the juristic office a process it can explain to residents.

WHD Disinfection Spraying on Srinakarin for Condos, Housing Estates and Commercial Buildings

According to the service information, WHD's trained technicians spray and/or ULV-fog (Ultra Low Volume fine mist). This suits large areas such as car parks, lobbies and long corridors, as well as small rooms with many corners like playrooms and rubbish rooms.

The disinfectant is CHEMGENE HLD4H, a medical-grade disinfectant from the UK containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. The service page says it covers viruses, bacteria and fungi, naming COVID-19, RSV, H1N1, H5N1 and the hand, foot and mouth virus, with a stated effectiveness of 99.99% (according to the service information).

Approvals and endorsements listed on the service page include the Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019. Customers include hospitals, schools, malls, airports, offices, airlines, banks and residential buildings.

Workflow for a high-rise

1. Book: Share the building name, its position on Srinakarin, the flooded areas (car park, rubbish room, lobby) and any other common areas to treat. Call 065-556-6294 or LINE @whd268.
2. Prepare: Remove mud, wash down, discard playroom mats and carpets that soaked up water, take small toys away to wash, and ask residents to move cars out of the treatment zone where possible.
3. Technicians spray: Zone by zone, by spraying or ULV fogging; areas are cordoned off and residents asked to keep out.
4. Wait about 30 minutes: According to the service information, and follow the technicians' re-entry time for each zone.
5. Reopen: The juristic office announces the reopening of common areas with the date and time of treatment.

According to the service information, customers receive a free CHEMGENE spray and WELLGIENIC wet tissues, and a tax invoice can be issued, which helps condominium and housing-estate juristic persons with their accounts.

Honest limits: spraying is done only after mud removal and washing. It does not replace cleaning, does not dry damp walls or ceilings and is not medical treatment; anyone who is ill should see a doctor. We do not claim zero residue, so everyone should leave the zone during application and return at the time the technicians advise. Units where a musty smell lingers can add the residential ozone disinfection service.

10 Reasons Condos and Buildings on Srinakarin Should Book Spraying After the Flood

1. Water from Lam Sali to Sukhumvit 77 ran into each building's lowest areas, the car park and rubbish room everyone passes through.
2. Common areas carry germs to every floor via lift buttons, handrails and pushchair wheels.
3. The playroom needs confidence before it reopens; the service covers hand, foot and mouth and RSV viruses according to the service information. Read more on the disinfection service page.
4. ULV fogging suits wide car parks, covering more evenly than hand wiping.
5. Medical-grade disinfectant from the UK, CHEMGENE HLD4H, used in hospitals and airports.
6. Back in use after about 30 minutes according to the service information, minimising common-area closures.
7. Documented references for the committee meeting: Department of Medical Sciences, Mahidol University, NHS England and EN 14476, on the certification page.
8. Tax invoice available for juristic persons and companies in Bang Kapi, Suan Luang and Prawet.
9. Clear communication with residents, with a date and an accountable provider.
10. Free spray and wet tissues for daily follow-up on lift buttons and parcel lockers. Book on the WHD disinfection spraying page.

Before and After: Common Areas of a Srinakarin Condo

Results depend on preparation and ongoing moisture control. Deeply mouldy or still-wet materials must be dealt with separately.

Example Case: A Condo Near Lam Sali and a Small Showroom Between Phatthanakan and Sukhumvit 77

Example case: a typical scenario, not a verified customer review.

Pattra's condo: After reading up and calling for advice, Pattra planned a three-day sequence. On day one, housekeeping cleared mud from the car park drain channels, threw out the playroom's soaked rubber mats and asked residents to move cars off the ground level. On day two, fans and dehumidifiers ran in the rubbish room and storerooms. On day three, the technicians treated the car park, rubbish room, lobby, the lift halls connected to the car park, the playroom and the gym. The juristic office cordoned off each zone and posted staff to inform residents. After the advised time, the playroom reopened with new rules: wash hands before entering and wipe toys every evening. The mother whose child had mouth sores was advised to take the child to a doctor and keep him out of shared spaces until the doctor said otherwise.

Wit's showroom: Wit runs a small motorcycle showroom on Srinakarin between Phatthanakan and Sukhumvit 77. Water covered the sales floor and the customer lounge. After washing, the lounge still smelled musty from a fabric sofa. He threw the sofa out, washed the floor again and had the team spray the showroom, lounge, toilet and the contract desk customers touch. He reopened the same afternoon after the advised time and filed the tax invoice as a business expense.

Both cases share the same order: remove damaged materials and dry the space first, then spray as the finishing step.

Checklist for Juristic Offices and Building Owners on Srinakarin and Phatthanakan

Before spraying

• Have an electrician inspect switchboards, plant rooms and pumps that were submerged.
• Staff cleaning the car park wear boots, rubber gloves and masks, with cuts covered.
• Clear mud from car park drain channels and sumps.
• Discard carpets, rubber mats, fabric seats and cardboard boxes that soaked up water.
• Wash small toys in soapy water; throw away soft or sponge toys that were submerged.
• Discard food and ingredients in ground-floor shops that touched floodwater.
• Run fans and dehumidifiers in windowless rooms.
• Notify residents in advance of the date, time and zones to be closed.

After spraying

• Re-enter at the advised time and ventilate.
• Rewash food-contact utensils in ground-floor shops before use.
• Set a wiping schedule for lift buttons, handrails, parcel lockers and glass doors.
• Set traps or hire pest control if rats are still seen.
• Watch car park walls for water marks and mould over the following weeks.
• Advise residents and staff with fever, calf pain, severe diarrhoea, or children with mouth sores and rashes, to see a doctor.

FAQ: Post-Flood Disinfection Spraying on Srinakarin

Q: Only the car park flooded, not the units. Do we still need spraying?
A: The car park and lobby are everyone's route in and out. Germs in flood sediment travel to every floor on shoes and wheels, so treating common areas after washing lowers risk for the whole building.

Q: Do residents need to move their cars?
A: Where possible, yes, so the disinfectant reaches floors and pillars, and everyone should leave the zone during application.

Q: When can the playroom reopen?
A: According to the service information, wait about 30 minutes after spraying and follow the technicians' re-entry time. Discard absorbent materials and wash toys before spraying day.

Q: What does the disinfectant cover?
A: According to the service information, CHEMGENE HLD4H covers viruses, bacteria and fungi; the page names COVID-19, RSV, H1N1, H5N1 and the hand, foot and mouth virus.

Q: Will the musty car park smell go away?
A: If the smell comes from sediment and surface microbes, washing plus spraying helps. If water still stands in drain channels or walls are damp, fix that first. Odour in enclosed rooms can also be addressed with ozone treatment.

Q: Can the juristic office get a tax invoice?
A: Yes, according to the service information.

Q: A staff member waded through water and now has a fever. What should they do?
A: See a doctor right away and mention the floodwater exposure, as it may be leptospirosis. Disinfecting a building is not treatment.
