Photos as evidence: bookends, meter shots, run hours

On a water-damage job, the photos are the record. Months later, when an adjuster asks how many days the equipment ran or what a wall read on day three, nobody remembers. The photos either answer the question or they do not.

This guide is about what job photos can prove, what they cannot, and the traps that make a good photo say the wrong thing. It is written for crews who take the photos, adjusters who rely on them, and homeowners who want to know what their file shows. I use CompanyCam for this in the office I run, but none of it depends on the app.

Bookends: how most jobs are actually photographed

Most crews photograph a job as bookends. They shoot plenty on install day and on removal day, and very little in between.

That pattern is normal, and it is not a defect. Equipment installed on the first day and removed on the eighth was in the house on the fifth, whether anyone took a picture or not.

What the gap does tell you is how a claim will hold up if an adjuster asks for monitoring records. That is a different question from whether the job was billed honestly. So I report the gap as a column, never as a verdict.

Three verdicts, not two

When I check billed days against the photos, I use three outcomes:

• Supported. The install is photographed, the removal is photographed, the two bracket the billed days, and no crew note contradicts them.
• Unsupported. The billed days run past anything any photo or note covers. For example, days billed after the last photo with no removal ever shown.
• Contradicted. A document and a photo disagree outright. For example, a written narrative gives one moisture reading and the meter photo shows another.

The middle category is where most problems live. The fix for it is upstream: in how crews document the job, not in how the paperwork gets written afterward.

How photos fit the invoice

A mitigation invoice makes dated claims, so it can be tested against photos. The cleanest invoices tie every dated labor line to a timestamped photo. The days in between are billed only as equipment running, labeled as "running, no visit," with no labor or supervisory hours claimed for them.

That convention is correct billing. It matches what the photos can show.

A rebuild invoice is different. A lump-sum rebuild line asserts nothing dated, so "no photograph covers this" would be a false finding. When the test does not apply, say so instead of forcing it.

Meter shots: read the photo the right way up

Moisture meter photos are some of the most useful evidence on a job, and some of the easiest to misread.

A technician holding a pin meter against a ceiling often photographs it upside down. Seven-segment digits turned upside down are still valid digits, and the string reverses too. A reading of 05.6 renders as 950, and a reader trying to make sense of it can land on 39.5. Both are wrong. On a rotated display, 5 and 2 swap, 9 and 6 swap, and 0, 8 and 1 look the same.

How to spot an upside-down photo:

• The maker's logo reads inverted.
• The mode and hold buttons are on the wrong sides.
• The bargraph runs the wrong way.
• The percent sign sits to the left of the digits instead of the right.

Two quick sanity checks catch a bad read without zooming in:

• The bargraph. A lit segment at the DRY end cannot be a high wood moisture reading.
• The printed range on the case. On the meter in this example, 5 to 50 percent for wood and 1.5 to 33 percent for building materials. A value outside the range is a misread, not a measurement.

One more trap: the same meter can show relative humidity, wood moisture, or a relative scale. The mode indicator has to be read off the display. Without it, the number is only "as displayed."

Run hours: the evidence that is not evidence

Dehumidifiers have hour meters, and a photo of one looks like perfect proof of how long it ran. It is not.

Here is a real pattern, with the job details left out. Three dehumidifiers on the same job were photographed within the same minute on install day. They read 02:04, 17:01 and 18:29. No set of units installed together can show a sixteen-hour spread. The same frame showed the crew still unloading that equipment from the truck.

The explanation is simple: the crew does not reset the timers. Units arrive carrying hours from the last job. A run-hour panel cannot date an install or prove a duration unless something independent dates the install.

What does date a job:

• Photo capture times.
• Install and removal sheets whose printed address matches the claim.
• The first and last capture dates on the job's photo project.

The document that beats a photo

One document dates the end of a job better than any photo: a signed certificate of completion. It prints the completion date on its face, and the client signs it. That is the client attesting to the date, not the contractor recording it.

The check worth running is easy. Compare the completion date on the certificate against the last day the invoice bills. Where they disagree, that gap is the finding.

Supervisory time from the same photos

The photos also carry supervisory hours. My rule: hours for a job on a day run from the first photo to the last, plus 30 minutes of drive time, billed in half-hour steps and always rounded up. A day with only one photo has no span, so it gets flagged for review instead of guessed.

A short field checklist

For crews:

1. Photograph the install and the removal of every unit, with the job address visible on any sheet.
2. Hold meters right side up, with the mode showing.
3. Take a first and last photo every day you are on site.

For reviewers:

1. Check that photos bracket the billed days.
2. Read meter photos the right way up and check them against the printed range.
3. Ignore run-hour panels unless something independent dates the install.
4. Look for a signed completion certificate and compare its date to the invoice.
