Field Photo Documentation - Before, During, After Protocol

Why this matters

Photos win disputes. The customer who claims you scratched the floor, the insurance adjuster who needs to see the failed component before disposal, the inspector who wants proof the cleanup was completed, the warranty manager who needs to see the defect at the time of install - every one of them is downstream of whether the tech took the photo. A documented before-during-after protocol turns a habit-dependent practice into an institution. This SOP defines what to photograph, when, from what angle, and how to store it so the photos are findable, dateable, and defensible months or years after the job closed.

When the protocol applies

Three job categories trigger the full protocol.

• Any job over a defined dollar threshold (set per company; commonly the threshold where a callback or dispute carries real cost).
• Any job involving a system or component that will be enclosed, buried, or covered (in-wall plumbing, in-slab electrical, foundation waterproofing, roof underlayment, ductwork being drywalled over).
• Any job at a property with visible pre-existing damage that could be attributed to the tech.

For smaller jobs, an abbreviated protocol applies: arrival photo, completion photo. The protocol scales to the risk.

The four photo categories

Every full-protocol job produces photos in four categories. Treat each as required, not optional.

1. Approach and arrival: vehicle parked, property frontage, entry path, any pre-existing damage near the work zone.
2. Pre-work staging: the work area before any tools or materials are placed, condition of surfaces, condition of equipment to be serviced, any conditions that affect the scope (corrosion, prior repairs, code violations encountered).
3. In-progress: critical hidden conditions captured before they are covered, model and serial numbers of installed equipment, part numbers on installed components, fittings before they are insulated, electrical connections before they are taped, plumbing connections before they are concealed.
4. Completion: finished work in operation, work area cleaned, any items moved returned to original position, the customer's signed acknowledgment if captured digitally.

If a job involves multiple work areas (basement furnace and attic air handler), each gets its own four-category sequence.

Pre-work staging - what to photograph

The pre-work set is the evidentiary baseline.

• Wide shot of the work area from the entry direction.
• Close shot of the equipment being serviced. Capture model and serial plates legibly.
• Surrounding surfaces likely to be touched - floor near equipment, path from door, wall behind equipment.
• Pre-existing damage. Scratches, chipped paint, water stains, prior repairs - each finding individually with surrounding context.
• Conditions affecting scope - flooded crawl space, corroded service entrance, attic full of stored items obstructing access.

Anything you would not want to be blamed for, photograph before you start. Anything that would justify a price change, photograph before you start.

In-progress - what to photograph

If a leak appears two years later, the pipe joint photo taken before insulation went on tells the story.

• Model, serial, date code of every new component before installation.
• Connections, joints, terminations, seals before covered or insulated.
• Critical measurements supporting code compliance - clearance to combustibles, drain slope, depth of buried conduit, shear-wall fastener spacing.
• Condition of removed parts on a clean surface. Show what failed.
• Permits posted, inspection tags placed, equipment labels affixed.

Completion - what to photograph

• Finished work from the same angle as the staging shot, for direct comparison.
• Equipment operating - flame visible at burner, water flowing, condenser fan spinning (motion blur proves it ran).
• Work area cleaned. Floor swept, tools removed, materials packed out.
• Pre-existing damage from the staging set, re-shot - shows the condition did not worsen.
• Final invoice, signed work order, completion certificate.

Angle, lighting, and framing rules

• Hold the phone level. Tilted shots distort perception.
• Fill the frame with the subject.
• Two shots of important items: one wide for context, one tight for detail.
• Light the subject. Use the flash in dim areas - crawl space and attic shots without flash are usually unusable.
• Include a known scale reference when relevant - ruler, hand, coin.
• Shoot model and serial plates straight-on, not at an angle.
• Date and time belong in EXIF metadata, not as visible overlays - metadata is more defensible than an editable overlay.

Metadata, storage, and retention

Photos that cannot be tied to a job and a date are worthless.

• Upload to the job record before leaving the site, or at the latest before end of shift. Photos sitting on a personal device are not company records.
• Storage system must preserve EXIF metadata - date, time, GPS coordinates, device. EXIF is what makes the photo evidence-grade.
• File naming convention: job number, photo category, sequence number. Example: J-2026-04812-staging-03.jpg. Burst sequences keep sequence numbers contiguous.
• Retention: keep job photos for the longer of the labor warranty period plus one year, or any applicable statute of limitations for property damage claims. Many states' statute on construction work is six to ten years; consult counsel on the exact retention period for your operating states.
• Backup: at least one redundant copy. SaaS backup, off-site backup, or both.

Customer-facing and privacy use

• Consent before publication. A signed photo-release on the work order covers external use (website, social media, marketing). Service-record use does not require external release.
• No people without consent. Faces, plates, mail with visible addresses - blur or crop before publication.
• The in-progress set serves the customer walkthrough. Show the customer during closeout - answers "what did I pay for?" before the question is asked.
• Bedrooms, bathrooms, home offices contain personal information; photograph only the work zone.
• If a photo inadvertently captures personal documents, do not delete (the photo is part of the job record) but crop the released copy.
