A Story from the Field: A Clean House, and Not a Single Photo

Khun Nong is a schoolteacher in her early fifties. She lives in a two-storey house, wooden upstairs and concrete downstairs, in Tambon Na Mueang, a short walk from the bank of the Mae Klong River in Mueang Ratchaburi. Her husband and their university-age son share the house with her. This year the Mae Klong pushed into the ground floor almost to waist height and stayed for nearly a week. As soon as the water went down, the family shovelled out the mud, scrubbed the floors and called in a team to disinfect the house and run an ozone treatment, because the living room smelled badly of damp and a long band of black spots had appeared along the lower wooden walls.

Three months later, Khun Nong wanted to talk to a carpenter about replacing the ground-floor boards, and she also wanted advice from the company that holds her home insurance policy. Both of them asked her the same kind of question: "Do you have photos from when the water came in, and from after the clean-up? What exactly was damaged, and what has already been done?" She opened her phone and found pictures of the flooded street that she had sent to relatives, but almost nothing clear from inside the house. The service receipt had disappeared along with a pile of soaked paperwork. She could not even remember the date the team had come.

This happens in a lot of homes after a flood. In those first exhausting days, nobody is thinking about evidence. Everyone is thinking about getting the mud out and getting the family back to normal. That is completely understandable. But a little planning makes a big difference later. This guide is written for homeowners: what to photograph, which documents to keep and how to file everything, before and after professional disinfection and ozone treatment, so that the information is ready on the day you need it.

Why Photos and Paperwork Matter More Than You Think

• Talking to an insurer or a local agency: If you have home insurance, or you plan to contact a local office about flood assistance, clear photos and documents help you explain the damage. Whether anything is covered, and what you are entitled to, depends entirely on your policy or the agency's own rules, so always ask them directly. Photos do not guarantee any outcome; they simply make your explanation clearer.
• Planning repairs: Carpenters, painters and electricians can assess the work far more easily when they can see how the house looked straight after the water receded, rather than only seeing it once everything has dried and been tidied.
• Tracking whether mold comes back: Photos taken from the same spot once a month tell you immediately if a dark patch is spreading or a smell is returning, long before the problem grows into a major tear-out.
• Selling or renting the house in the future: Many buyers and tenants ask whether a property has flooded and how it was handled. An organized record lets you answer honestly and confidently.
• Avoiding family disagreements: When several siblings share the cost of restoring their parents' home, or take turns looking after it, clear records mean everyone sees the same picture and argues less.
• Preparing for the next flood: Ratchaburi sits on the Mae Klong, and high water may well return in future years. This year's record is your lesson about which rooms and which belongings are most vulnerable, and what needs to be lifted to a higher shelf first next time.

Paperwork is important, but it is never more important than health. A flooded house carries real risks. Floodwater brings in germs from drains and sewers, including bacteria that cause diarrhea and the bacteria linked to leptospirosis, and it can trigger skin infections and rashes. The mold that grows on walls, wooden panels and furniture afterwards can set off allergies and asthma, especially in children and older family members. Making the house safe always comes first. Collecting records should happen alongside the clean-up, not instead of it, and never in a way that puts anyone at risk.

Why the Usual Approach Falls Short, for Both Hygiene and Records

• Pouring on bleach, then photographing a white wall: The surface looks clean, but mold that has grown into the timber or into the back of plasterboard is often still there. The photo you end up with does not reflect the real damage, and it does not prove the cause was dealt with.
• Running fans until everything is dry, then taking pictures: The waterline fades, which makes it much harder to show how high the water reached. Meanwhile, fans blow mold spores from one room into the next.
• Air fresheners and charcoal bags: These mask the smell for a while, but there is nothing to show that the source of the odor has actually been removed. Once the house is closed up again, the musty smell tends to come back.
• Painting over the stains straight away: The "after" photo looks lovely, but if the wall is still damp, the mold pushes the new paint into blisters within weeks, and there is no "before" photo to compare.
• Keeping receipts in a ground-floor drawer: If the water returns, the most important documents are damaged all over again.

A better approach is to photograph the true condition of the house before the big clean-up, let professionals deal with the root cause through disinfection fogging and ozone treatment, and then photograph the same spots again afterwards, keeping all the paperwork somewhere safe and dry.

Step 1: "Before" Photos. What to Shoot and How

A mobile phone is perfectly adequate. Turn on the date and time setting in your camera, or use an app that stamps the date on each image. Then work through this list in order, so that nothing is forgotten in the rush.

1. The front of the house and the house number: Make sure the house number or the soi sign is visible, so there is no doubt about which property the photos show.
2. A wide shot of every room: Stand in the doorway and capture the whole room. Take two angles per room: one from the door looking in, and one from the far corner looking back towards the door.
3. The waterline on the walls: Hold a tape measure or a long ruler against the wall from the floor up to the tide mark, and photograph it so that the numbers are easy to read. This one picture explains the flood height better than any description.
4. Close-ups of mold: Wall corners, skirting boards, the back of cupboards, the space under the stairs, the ground-floor ceiling and the legs of furniture. Put a coin or a pen next to each patch so the size is obvious.
5. Damaged belongings: Wardrobes, beds, mattresses and electrical appliances. Photograph the whole item and, where there is one, the model label or serial number, before anything is thrown away.
6. The electrical board, water pump and water tank: Photograph them from the outside only. Do not open the electrical board yourself; leave that to a qualified electrician.
7. A walk-through video: Walk slowly around the house while saying out loud which room you are in and what you can see. Three to five minutes is enough. This video is extremely useful months later, when you need to retell what happened.

Safety while photographing: Wear rubber boots, rubber gloves and a mask. Do not walk through standing water if you are unsure whether there is an electrical leak. Never touch mud or mold with bare hands, and wash your hands and your phone case afterwards. If anyone in the family has asthma or a weakened immune system, they should not be the person who goes in to take the photos.

Step 2: Documents to Keep, from Booking Day to After the Service

• A contact log: The date you called, the name of the person you spoke to, and any LINE messages that summarise the scope of work. Take screenshots and save them.
• The quotation or job description: It should show which areas are covered, how many floors, and which services were agreed, for example disinfection fogging for the whole house and ozone treatment for the ground floor only.
• Receipts or tax invoices: Photograph each one the moment you receive it, then keep the original in a waterproof plastic sleeve.
• The name of the products used: Ask, and write down, the name of the disinfectant, for example Chemgene HLD4H, and the methods used, such as fine-mist fogging and ozone treatment. Later on you will want to know exactly how the house was treated.
• Aftercare instructions: How long to ventilate, which spots to keep an eye on, and when to call back. Write them down, or ask the team to send them to you as a message so they are stored automatically.
• Documents from other trades: The electrician's inspection note, receipts for removing ceiling boards or replacing floors. Keep them together, so you have a complete picture of how the whole house was restored.

It can feel like a lot, but in practice each item takes less than a minute to capture if you do it on the day. Trying to reconstruct the same information months later is far harder.

Step 3: "After" Photos from the Same Angles

The secret of a useful before-and-after set is simple: same angle, similar light. Open the "before" photo on your phone, stand in exactly the same position, frame the shot the same way, and only then press the button.

• Only take "after" photos once ventilation is complete and the team has told you it is safe to go back inside.
• Photograph every spot where you previously recorded mold, even if you can no longer see any stain.
• Write a short note about the smell that day, such as "living room: musty smell clearly reduced; storage room: faint smell remaining." Smell cannot be photographed, so your notes are the only record.
• Repeat the same photos on day 7, day 30 and day 90 after the service, from the same angles, to see the long-term trend.
• If you have a handheld moisture meter, note the wall moisture reading at the same points. This helps you decide when the wall is dry enough to repaint.

This set of photos is useful for you and for the service team. If anyone needs to come back for a re-check, they can see immediately which areas have improved and which need further attention, instead of relying on memory.

Step 4: Build a File You Can Search in One Minute

A document you cannot find is as good as a document you do not have. We recommend keeping both a digital file and a paper file.

The digital file

• Create a main folder called something like "House Flood 2026" in the cloud storage service you already use, with sub-folders such as 01 Before clean-up, 02 Service day, 03 After service, 04 Documents and receipts, and 05 Follow-up.
• Name each file with the date and room, for example "2026-10-14 ground floor living room stair corner". You will thank yourself later when you search.
• Back up the files in at least two places, for instance the cloud plus a USB drive kept upstairs.
• Share the folder with one other family member, in case your phone is lost or broken.

The paper file

• Use a zip-lock plastic folder for original receipts, quotations and contractors' paperwork.
• Write a one-page summary for the front: the date the water came in, the date it receded, the highest water level, the date of disinfection and ozone treatment, and the company name and phone number.
• Keep the file upstairs or on a high shelf, together with other important documents such as the land title deed and insurance policy.

With this system, when a carpenter, an insurer, a buyer or a relative asks a question, you can open one folder and show them the answer.

One more tip from families along the Mae Klong: set a recurring reminder on your phone for the first day of each month for the next six months. When the reminder appears, spend five minutes walking through the house, re-shooting the same corners and adding a line to your notes about smell and dampness. It is a small habit, but it turns a pile of pictures into a genuine history of your home's recovery, and it catches small problems early, while they are still easy and inexpensive to fix.

The WHD Disinfection and Ozone Process, and When to Take Photos

1. Site survey: The team walks through every room with you. This is the ideal moment to photograph any spot the team points out as high-risk.
2. Clean-up advice: If there is still mud, soaked mattresses or swollen plasterboard, the team will recommend removing or clearing them first. Photograph anything you are about to throw away.
3. Disinfection fogging with Chemgene HLD4H: ULV fine-mist foggers carry the disinfectant into room corners, stair recesses, under furniture and onto surfaces that hand-wiping cannot reach.
4. Ozone shock treatment: The house is closed and an ozone generator runs at a controlled dose, helping to destroy mold spores and break down the odor molecules trapped in timber, fabric and walls.
5. Ventilation: Doors and windows are opened until the ozone has broken down, before the family is allowed back in.
6. Re-check and advice: The team checks the smell and the risk points again. This is the moment to take your first set of "after" photos and to write down all the aftercare advice.

Ozone safety: No people, pets or plants may stay inside during treatment, and you must never go in to take photos while the ozone is running. Sensitive electronics, artworks and rubber items should be removed or covered as advised. The team controls the ozone dose according to the size of the space, and the house must be properly ventilated before anyone re-enters.

Before and After: Khun Nong's Home File

What Homeowners Tell Us

"The first time, I didn't think about photos at all. I just wanted the house to stop smelling. When I had to talk to the carpenter, I couldn't answer anything. Later the team suggested taking pictures from the same angles and keeping them. Now I have one folder for everything, and I can show anyone who asks. Most importantly, I can see for myself that the house really is better."

Frequently Asked Questions

Q: I have already cleaned the house and have no "before" photos. What can I do now?
A: Photograph the current condition in as much detail as possible, especially any remaining waterline marks. Ask neighbours, relatives or your community LINE group for photos they took during the flood, and write down what you remember right away, while the details are still fresh.

Q: Do before-and-after photos guarantee that insurance will pay?
A: No. Photos and documents are supporting information only. Coverage depends on the terms of your own policy, so please ask your insurer directly.

Q: Can I ask the team to take photos while they work?
A: You are welcome to ask on survey day, but we recommend that you always take your own set as well, so that you have photos from the exact angles and times you want.

Q: Can I go inside to take pictures during the ozone treatment?
A: No. Nobody may be inside during ozone treatment. Take your photos only after ventilation is complete and the team says it is safe to re-enter.

Q: How long should I keep these records?
A: At least until all repairs are finished and the next rainy season has passed. If you plan to sell or rent the house, keep them for longer.

Q: Should tenants keep a file like this too?
A: Yes. Ideally the tenant and the landlord share the same set of photos and agree in writing who is responsible for which part of the clean-up and repairs, which avoids misunderstandings later.

Q: Which parts of Ratchaburi do you serve?
A: Contact us about Mueang Ratchaburi, including Na Mueang, Ko Phlappha, Khung Nam Won, Don Tako and Huai Phai, as well as nearby districts. The team will confirm dates and routes when you get in touch.
