A client calls two weeks after the bathroom is finished: there's a crack in the hallway tile outside, and it must have been your crew carrying the old tub out. Maybe it was. Maybe it was there before. Without a photo it's your word against theirs, and on a small job the cheapest way out is usually to fix it for free.
Photos settle most of these arguments before they start, but only if they were taken at the right moment, show what they need to show, and can be found again. This piece is about that practice for small construction and trade crews; most of it works for cleaning crews and kitchens too.
Six moments worth a photo
1. Before you touch anything
Walk the work area and the route in on day one. Floors, door frames, the driveway, the neighbour's fence, the lawn where the skip will go. Anything already cracked, stained or dented gets a close-up. Ten minutes of photos here is the single best insurance a small contractor can buy.
2. Work that is about to be covered
Footings and rebar before the pour, pipes and wiring before the drywall, waterproofing before the tile, insulation before the ceiling. Once covered, the only way to show it was done right is a photo or a demolition. Inspectors, the next trade and a future buyer all benefit.
3. Deliveries and damage
A pallet of tile with a broken corner, the wrong window size, a door delivered scratched. Photograph it on the pallet with the delivery note in frame, before it is signed for or unwrapped further.
4. Surprises
Rot behind the old cabinet, an unmapped pipe, rock where the plan said soil. A photo taken the moment it's found is the start of a change order the client will accept, because they can see what you saw.
5. Each finished item
A punch-list line closed, a fixed leak, a tidy site at the end of the day. An after photo from the same spot as the before photo is proof that it was done and what done looked like. (How to run the punch list itself is in construction punch lists.)
6. Readings and checks
In a kitchen it's the walk-in thermometer, the sanitiser test strip, the clean hood filter. On a site, the level on a slab, a moisture meter reading, the gas test before the hot work. A photo of the reading beats a tick in a box, which is the point made in restaurant opening and closing checklists.
A photo proves something only if a stranger can tell what, where and when without asking you.
How to take a photo that proves something
Wide, then close. One shot from the doorway that shows which room and which wall, then the close-up of the crack. A close-up alone could be anywhere.
Put a reference in the frame. A tape measure along the crack, a pencil for scale, the room's door, the address on the skip.
Same spot, same angle for after. Stand where you stood for the before photo. Side by side, they make the case without words.
Light it. Turn the work lights on or use the flash for dark corners. A dark photo of a dark corner proves nothing.
Don't edit it. No filters, no crops that remove the context. Keep the original.
Take it now. A photo from the day is evidence; one taken a week later of "how it was" is a guess.
Timestamps: useful, not magic
Every phone stores the time a photo was taken, and usually the place, in the file's metadata. That helps, but it can be edited with free tools, and a phone's clock can be wrong. In US courts a photo is normally admitted because someone who was there testifies that it fairly shows what it claims to show (Federal Rule of Evidence 901); a record kept as part of the normal running of the job helps too. In practice, very few of these disputes reach a court. What settles them is a photo taken at the time, filed with the task, by a named person, in a system that records when it arrived.
That last part is where most crews fall down. A photo in one person's camera roll is hard to find in six weeks and gone if they leave. A photo attached to the task it proves, in a shared list, is found in seconds by anyone on the job, with who added it and when.
Put the photo on the task
One task per thing that needs proving. "Hall tile, existing crack at the bathroom door" is a task with a before photo, not one of 300 pictures in an album.
Before photo when you open it, after photo when you tick it. Then the task's history is the evidence.
Make it the rule for certain tasks. Hidden work, damage, readings: no tick without a photo. Everything else, use judgement; nobody needs a photo of a swept floor every day.
Share the list, not the camera roll. The client can be shown the before photos at the start. Being shown them up front is often enough to stop the argument happening.
In tick-tock-done, pictures and videos go on the task itself, in a personal list or a team's. The app records who added each one and when it arrived.
Privacy basics
A job-site photo often shows more than the job: a family's living room, a child's drawing on the fridge, a letter on the counter, a worker's face, a car number plate. Some habits keep that under control.
Shoot the work, not the house. Frame tight enough to show the problem and its location, not the client's belongings. Turn papers and screens away or leave them out of frame.
Ask before anything leaves the job. Using a photo of a client's home on your website or social media needs their permission, every time. Photos for the job record don't.
Mind the location. Phone photos usually carry the GPS position of the house. Before posting one publicly, remove it: on an iPhone, tap Share, then Options, and turn Location off; on Android, the share or edit screen of the Photos app has a similar setting. tick-tock-done saves each uploaded picture again in a smaller size, which drops that location data; the original stays on the phone.
Crews have a say too. Photos of people at work can be needed (safety gear, who was on site), but don't post someone's face without asking, and don't use photos to watch people instead of work.
Keep only what you need. Keep job photos for as long as the warranty and your records need them, and in one place, not scattered across personal phones.
Attach before and after photos to the tasks they prove, in a list the whole crew shares.
See it for construction crewsWhat this does not cover
This is not legal advice. Whether a photo is accepted, and what consent you need to take or publish one, depends on your state or country and the situation.
Insurance claims have their own rules. Your insurer may want photos in a particular form or within a deadline; read the policy.
We found no independent data on how often photos prevent disputes. The figures quoted by photo-app vendors could not be traced to a source, so none are given here.
Video and drones follow the same ideas but have more rules (recording sound, flying near people); they aren't covered here.
