A Story from the Field: The Room Where Mother Prays Every Evening

Pa Boonruean is seventy-two and lives in a two-storey wooden house on the bank of the Chao Phraya River in Chaiyo district, Ang Thong, together with her son and her granddaughter. Her favorite room in the house is the small shrine room on the ground floor. It holds a teak altar table set that her late husband bought when they married, a small Buddha image received from the temple near their home, framed amulets given to her by older relatives, and a wooden Buddha shelf on the wall where she has lit incense and chanted every evening for almost fifty years.

During the 2026 floods, the river rose into the house to nearly knee height. Her son hurried to carry the Buddha image and the framed amulets upstairs with great care, but the teak altar table, its cloth covers and the shelf fixed to the wall had to stay where they were. The water sat in the room for several days before it finally drained away.

When the water was gone, Pa Boonruean walked into the shrine room for the first time. A damp, musty smell mixed with river mud rose up so strongly that she covered her nose with her hand. The legs of the altar table were stained with water marks and dotted with white mold. The yellow altar cloth was speckled with black spots. A line of green mold was spreading across the wooden wall beneath the Buddha shelf. Even the Buddha image that had been carried upstairs had a thin white bloom on its base, because the upper floor had become damp too.

"Mother does not want anyone to handle the Buddha image carelessly, but she also does not want to pray in a room that smells like this," her son explained. Many families in Chaiyo, Pa Mok, Wiset Chai Chan and Mueang Ang Thong are facing exactly the same question: how can they restore their shrine room so that it is clean and healthy again, while keeping the deep respect they have for the sacred objects their families have honored for decades?

Why Shrine Rooms Become Musty and Moldy So Easily After a Flood

1. Shrine rooms are usually kept closed

Many Thai homes keep the shrine room small and quiet, with the door closed most of the time. After the water drains, that same calm, closed space traps moisture with almost no air movement. It is exactly the environment mold prefers.

2. The materials in the room soak up moisture

Wooden altar tables, wooden shelves, altar cloths, silk drapes, dried flowers, old garlands and paper chanting books all absorb water and hold it inside. If they are not taken out to dry, the musty smell grows stronger every day.

3. Incense residue combines with damp

Years of incense smoke leave a fine layer of soot on ceilings and walls. When that residue becomes damp, the walls look dull and develop a distinctive smell. Mixed with river mud and mustiness, it creates an odor that clings stubbornly and is hard to remove.

4. The health of older family members

The people who use a shrine room most are often older family members who sit and chant for long periods in a closed space. Breathing mold spores every day can trigger allergies, a persistent cough or asthma attacks. Mud left in the house may also carry E. coli, which can cause diarrhea, and standing water around the house carries a risk of leptospirosis.

What Not to Do in a Shrine Room After a Flood

In the rush to make the room presentable again, families sometimes reach for the strongest cleaner in the house. With sacred objects, gentle and careful is always better.

• Do not clean Buddha images with bleach or harsh chemicals. Images finished with lacquer and gold leaf, painted gold, or cast in old metal can be dulled or damaged by strong chemicals. Avoid bleach, strong alcohol and stiff brushes.
• Do not put sacred objects through ozone treatment without advice. Antique lacquered and gilded items, silk cloths and certain sacred objects should be moved out of the room before treatment so they are not exposed to ozone unnecessarily.
• Do not burn extra incense to cover the smell. More smoke in a closed room irritates the airways and does nothing about the mold that causes the odor.
• Do not repaint or varnish the altar table straight away. If the wood is still damp, the coating seals the moisture in, leading to mold beneath the finish and greater damage to the wood.
• Do not leave wet cloths and old flowers in the room. Damp fabric and decaying flowers feed mold. Take them out to be washed or dealt with in a way that fits the family's beliefs.

The Solution: The Family Moves the Sacred Items, Then the Room Is Fogged and Ozone-Treated

World Health Disinfection (WHD) provides a professional disinfection fogging service using CHEMGENE HLD4H, applied with ULV foggers that reach corners, the space under the altar table and the joints in wooden panels. This is combined with our ozone treatment service, which tackles airborne mold spores and breaks down musty odor trapped in walls and ceilings.

In a shrine room, the most important principle is that the family moves the Buddha images, amulets and offerings out of the room themselves, according to their own beliefs. Many families first light incense and quietly ask permission before moving a Buddha image, wrap it in a clean white cloth, and place it somewhere high, dry and clean for the time being. Our team never touches or moves sacred objects, and we only begin work when the family is ready.

Our step-by-step process

1. Survey and conversation with the family. We ask which items the family wishes to move themselves, which fixtures cannot be removed from the wall, and which day suits them, for example avoiding Buddhist holy days or days when the family has a ceremony.
2. The family moves the Buddha images and offerings. The family handles these according to their beliefs. Altar cloths, dried flowers and wet papers are washed or dealt with as the family sees fit.
3. Initial cleaning. Mud is scraped away and stains wiped from the floor and table legs. We advise on methods that will not damage the wood.
4. ULV disinfection fogging. Chemgene HLD4H is fogged over the floor, the lower walls, the space beneath the altar table and the empty fixed shelf.
5. Closed-room ozone treatment. No people, pets or plants may be inside during treatment. We use a controlled ozone dose, and electrical items such as lamps or fans should be unplugged and moved out or covered.
6. Ventilation and re-check. The room is aired thoroughly and checked again for odor and mold. Only then does the family return the Buddha images to their place, in a room that is now dry and clean.

Basic Care for Buddha Images and Offerings with a Light Mold Bloom

This section is general guidance for families. It is not work our team does on the family's behalf, because caring for sacred objects should follow each household's beliefs and comfort.

• Start as gently as possible. Use a clean, dry microfiber cloth or a soft brush to lightly remove the bloom, in a well-ventilated place, wearing a mask.
• Lacquered, gilded or gold-painted images. Do not rub hard or use cleaning liquids. If mold is heavy or gold leaf is lifting, consult a craftsman experienced in restoring Buddha images.
• Framed amulets. If water got inside the frame, ask a trusted shop or craftsman to open it and dry it correctly.
• Silk drapes and altar cloths. Wash with clean water and dry completely in the sun, or replace them as the family feels is appropriate.
• Rest the images somewhere dry. While waiting for the shrine room to be ready, keep them high up, dry and in moving air. Avoid wrapping them in plastic, which traps moisture.

Setting Up the Shrine Room to Resist Damp in Future

After the recovery, many families take the opportunity to rearrange the shrine room so it copes better with humidity, while keeping its beauty and calm.

• Raise the altar table set on a low platform or base, and leave a small gap between it and the wall.
• Open a window to air the room every day after chanting, even for a short time.
• Use fewer incense sticks in a closed room, or light them near a window, to reduce soot build-up.
• Change fresh flowers and vase water often so water does not stagnate.
• For riverside homes along the Chao Phraya that flood often, consider moving the shrine room upstairs, if this suits the family.

Talking with Older Parents About the Shrine Room

For many older people, the shrine room carries memories of a spouse, of parents and of a lifetime of quiet devotion. Seeing it damaged can be upsetting, and sons and daughters who live far away often worry about how to handle the subject. A few gentle approaches help.

Ask before acting. Let the parent decide which items should be moved, who should move them and where they should rest while the room is restored. Even if a younger family member does the lifting, the decision belongs to the person who has cared for the shrine all these years.

Explain the plan simply. Describe the steps in plain language: the room will be cleaned, misted with disinfectant, treated with ozone while empty, aired out, checked again, and then the Buddha image will return to its place. Knowing the sequence reduces anxiety.

Choose an auspicious or convenient day. Some families prefer to avoid Buddhist holy days for this kind of work, or to choose a day that feels right to them. Our team is happy to fit in with those wishes.

Mark the return. Many families find it meaningful to light incense, offer fresh flowers and chant together when the Buddha image is placed back on the shelf. It turns the end of the recovery into a moment of comfort rather than just the end of a chore.

Why the Rest of the House Matters Too

A shrine room rarely exists on its own. If the whole ground floor was flooded, musty air and mold spores from the living room, kitchen and bedrooms will drift back into the shrine room even after it has been treated. That is why, in most riverside homes, we recommend treating the whole flooded floor in one visit and planning the shrine room as the first room to be ready, if the family wishes.

For houses where the upper floor became damp from rising humidity, it is worth checking bedrooms and wardrobes as well. Clothing, mattresses and curtains upstairs can develop mold weeks after the water has gone down. Our residential ozone disinfection service can cover these rooms at the same time, so the family is not dealing with the problem room by room for months.

Kitchens deserve special attention too, because many riverside families prepare offerings and food for monks there. Drains, the space under the sink and wooden cabinets often hold mud and odor long after the floor looks clean, so they should be cleaned and disinfected before the household returns to its normal routine of cooking and making merit.

A Simple Timeline for Restoring a Shrine Room

Every household moves at its own pace, but most shrine room recoveries in riverside homes follow a similar pattern. Knowing the stages in advance helps families plan and keeps older parents reassured.

Days 1 to 3 after the water drains: safety and sacred items. Switch off the electricity to the ground floor and have it checked before use. The family moves Buddha images, amulets and offerings to a high, dry place, following their own customs. Wet cloths, flowers and papers are taken out of the room.

Days 3 to 7: mud removal and first drying. Scrape mud from the floor and the base of the altar table, open doors and windows on dry days, and remove standing water from corners and under furniture. Take photos of any damage for your records.

Week 2: fogging and ozone treatment. When the room is empty of sacred objects and the worst of the moisture has gone, our team fogs the room with disinfectant and carries out ozone treatment, followed by thorough ventilation.

Week 3: re-check and return. We check again for odor and mold. If the room is dry and fresh, the family can return the Buddha image and offerings to their places.

Later: refinishing and improvements. Refinishing the altar table, repainting walls or raising the altar on a platform can follow once the wood and plaster are completely dry.

Protecting Yourself While Cleaning

Family members who clear mud and wet items from the shrine room should look after their own health as well. Wear rubber boots and rubber gloves, and a mask when brushing mold or handling musty fabrics. Keep children and elderly relatives away from the room while it is being cleaned, and wash your hands with soap before eating or drinking. Anyone who develops a fever, muscle aches or unusual tiredness in the days after working in floodwater should see a doctor and mention the flood, because early treatment of infections such as leptospirosis matters. Taking these simple precautions means the family can focus on caring for the shrine room without anyone becoming ill along the way.

Before and After: Restoring the Shrine Room

A Word from the Family

"The team asked my mother first what she wanted to take care of herself. She lit incense and asked permission, and I carried the Buddha image upstairs myself. The team waited until we were ready before they started fogging and treating the room. After it was aired, the musty smell was gone. Mother is back to chanting every evening and says the room feels much more open."

— Pa Boonruean's son, Chaiyo, Ang Thong (a representative scenario based on field experience)

Frequently Asked Questions

Q: Will your team move the Buddha images for us?
A: No. Our team does not touch or move sacred objects. The family moves them according to their beliefs, and we only begin once the family is ready.

Q: The Buddha shelf is fixed to the wall. What can be done?
A: Once the family has removed the images and offerings, a fixed shelf can be fogged and ozone-treated together with the room. We apply a fine mist in a suitable amount; we do not pour or soak.

Q: Can Buddha images go through the ozone treatment too?
A: We recommend moving them out first, especially lacquered, gilded, painted or antique images, to avoid any effect on their surfaces. Care of the images should be gentle and follow the family's beliefs, or be guided by an experienced craftsman.

Q: When can we go back into the shrine room after ozone treatment?
A: The room must be ventilated according to our team's guidance before anyone enters. Timing depends on room size and the severity of the problem, and we will explain this before work begins.

Q: Will our moldy teak altar table look beautiful again?
A: Fogging and ozone treatment deal with germs and odor. If the wood surface is stained or the finish damaged, a carpenter may need to sand and refinish it later, once the wood is completely dry.

Q: What should we do with offerings that are too damaged to keep?
A: That is a decision for the family, according to their beliefs. Many families offer such items to a temple or ask a monk they know for guidance. We suggest not throwing them away with ordinary rubbish without first seeking advice.

Q: Our shrine room is upstairs and did not flood. Does it still need treatment?
A: If the ground floor was flooded for a long time, humidity often rises and causes a mold bloom on images or walls upstairs. Check for smell and spots first; if you find them, we can assess whether the upstairs shrine room should be treated as well.
