How to document existing damage before you start work

A painter finished a two-week interior job, got paid, and moved on. Ten months later the homeowner sent a photo of a gouge in the hardwood by the stairs and a bill for the refinisher. The painter knew the gouge was there before he ever carried a drop cloth through that door. He was almost sure of it. But almost sure is not proof, and he had no photo from day one, so he split the repair to keep the peace. Two hundred dollars for damage he did not do, because the only record of the floor’s condition lived in his memory, and memory does not hold up.

That is the whole reason to walk the job and photograph it before you start. Not because you expect a fight, but because the one time you get one, the house has already been standing for thirty years and every scratch in it is about to become yours. The camera is the cheapest insurance you will ever buy, and it costs you fifteen minutes on the front end.

Why the old damage becomes your damage

Here is the trap, and it catches good crews as often as sloppy ones. You show up, you do clean work, you leave. Weeks or months later the customer notices something wrong: a cracked tile, a scuffed door, a stain on the ceiling. In their mind, the house was fine before you came and it is not fine now, so you must have done it. They are not lying. They genuinely did not see it before because they were not looking. You are the change they remember, so you are the cause they assume.

Without a dated photo, you cannot answer that. You can say you did not do it, and they can say you did, and it comes down to whose word carries more weight in the moment, which is usually the person holding the checkbook. This is the same he-said-she-said that turns a callback into a two-week argument, and the fix is identical: you win it in advance, with a photo, or you do not win it at all. If you have never walked through how one of these fights actually plays out, the callback argument settled by a photo trail is the version every trade has lived.

The pre-existing-damage walk is the front-end companion to the proof photos you take at closeout. It is the same habit pointed at the start of the job instead of the end, and it belongs in the same proof and getting paid playbook.

Walk the job before your tools come off the truck

The rule is simple: nothing you brought touches anything in the house until the existing condition is photographed. Ladder stays folded. Drop cloths stay in the bag. You walk first, phone in hand.

Go room by room, not in a rush. You are looking for anything already broken, worn, scratched, cracked, or stained that a customer could later pin on you. Shoot it wide first so the room is identifiable, then shoot it close so the damage is clear. A tight photo of a cracked tile proves the tile is cracked; it does not prove which house or which day. You want both.

Talk while you walk if the customer is home. “I want to note the condition before we start, that scratch by the door and this stain on the ceiling, so we are all on the same page about what was here.” Nobody argues with that. It reads as careful, not defensive, and it does something quiet and useful: the customer sees the damage too, on day one, before you have touched a thing. Half your future disputes end right there, in the driveway, before they ever start.

A room-by-room checklist by trade

You do not need to photograph the whole house. You need to photograph the surfaces your trade puts at risk and the ones sitting closest to your work. Here is where the claims actually come from, by trade.

Painters and drywall. Floors under every wall you will cut in, hardwood scratches and gouges near baseboards, existing wall cracks and nail pops, window and trim chips, and any ceiling stain. The floor by the work is where the gouge claim lives.

Plumbers. Cabinet floors under sinks (water staining and swelling), existing wall and ceiling stains near the work, tile and grout condition in the bath, and the shutoff valves before you touch them. Old water damage becomes new water damage in a customer’s memory the moment you open a wall.

HVAC and electrical. Drywall around every register, panel, or fixture you open, attic and crawlspace access points, and the wall where the ladder lands. Anything you cut into, shoot the surrounding surface first.

Flooring, tile, and cabinet crews. Adjacent finished surfaces, door casings, existing subfloor condition, and the walls the material comes in past. The damage claim is almost always about the surface next to your work, not the one you replaced.

Anyone with a ladder or a hand truck. The path from the truck to the work. Doorframes, entry floors, stair treads, and corners. Half the damage claims in any trade are a scuff on the way in, not at the work itself.

That is not a long list, and you will not photograph every line every time. The point is to know, before you unload, which three or four surfaces on this job are the ones a customer could someday hand you a bill for.

Make the walk automatic, not a habit that fades

Here is the catch with everything above: it works right up until the morning you are behind, the customer is chatty, the crew is unloading, and you skip the walk just this once. Then that is the job the claim lands on. A habit that depends on remembering is a habit you will forget on exactly the wrong day.

The camera roll makes it worse, not better. Say you did take the photos. Ten months later they are buried in a phone with four thousand other shots, and you cannot say for certain which house or which Tuesday, which is the same weak spot the painter had. A photo you cannot date and place is barely better than no photo at all. If your proof already lives on someone’s personal phone, the photos on an ex-employee’s phone problem is the next one waiting for you.

The fix is to stop treating the walk as a separate chore and make it the first task on the job. When the pre-existing-condition photos are the thing that opens the work order, taking them is just how the job starts, the same way the huddle starts the morning. The walk stops being something you might skip and becomes something the job will not let you skip.

Where the record lives

This is what Crewmigo is built to hold. Every job gets its own thread that remembers, and the first task on that thread is the walk: shoot the existing damage, and the photos land on the task, dated and tied to that job, not scattered across a phone. Ten months later you scroll to day one of that job and the floor’s condition on the morning you arrived is right there, stamped and findable in seconds. The gouge that was there before you is on the record before your ladder ever came off the truck.

We are new, so the ask is small: put your next job on it, and take the walk-through photos as the first task. The one time a customer hands you a bill for damage the house already had, that fifteen minutes on the front end is worth more than anything else you did all week.
