# Construction photos: what they show and what to check
Portfolios and profiles
Use project photos to ask focused questions before selecting a sub. Check attribution, concealed work, records, references, and current credentials.
You are choosing a sub, and the finished-project photos look convincing. Use the photos to identify comparable work and ask better questions. Before deciding, check who did the work, before-cover photos, supporting records, references, and current credentials.
A clear photograph can document a visible condition. It cannot show concealed work outside the frame or tell you what a crew can take on today. Check what the photo shows. Work out which questions need another source.
## Confirm who did the work
Ask which company did the work shown and what its scope included. Distinguish installation, supply, management, and design. A photograph of a room can contain contributions from several firms.
Ask whether the example belongs to the current company, prior employment, or another contractor. Credit the experience to the right company or person. Ask which crew performed the work and who is being considered for your next job.
Start with a project label and a statement of the company's role. If the firm cannot identify its contribution, leave that question unresolved. A polished caption does not tell you who did the work unless it names their role.
Use [the construction portfolio guide](/guides/construction-portfolio/) to request an understandable project card. Focus the discussion on work like yours. The price of the house does not answer your scope questions.
## Read construction photos as evidence of visible work
Look for the visible subject, area, and stage. Ask the company to locate a close-up in a wider project view. Check whether the caption describes the same condition you can see.
Use this table to check what each photo shows:
| Image subject | What to examine | What to request next |
| --- | --- | --- |
| Finished room | Visible layout, surfaces, and interfaces | Role statement and relevant scope |
| Connection detail | The visible connection at that stage | Applicable drawing or product instruction |
| Before-cover assembly | The area photographed before closure | Stage context and relevant inspection or test record |
| Test setup | What equipment and arrangement are visible | The actual result and required procedure |
| Before-and-after pair | Whether both views represent the same scope | Dates, attribution, and status of completion |
The table offers questions, not a technical acceptance standard. Have the responsible professional check compliance against the requirements that apply. Do not infer a passing result from a selected image.
## Ask what the camera did not capture
Ask what sits outside the frame and what happened after the photo. A before-cover image may precede a correction or later work by another trade. A finished view may conceal the detail you need to assess.
Ask for photos from the same area that show the sequence of work. Keep context, detail, correction, and completion stages separate. Ask about a missing photo. Its absence does not automatically prove poor work.
For example, [PNNL's window guidance](https://basc.pnnl.gov/resource-guides/windows-and-doors-are-fully-flashed) emphasizes flashing integration before siding. A finished opening alone does not show that whole stage. Ask for the relevant evidence and the actual installation instructions.
For a roof-wall interface, [PNNL describes the water-management role of step and kick-out flashing](https://basc.pnnl.gov/resource-guides/step-and-kick-out-flashing-roof-wall-intersections). Ask about both the visible flashing and the parts you cannot see. Do not judge the assembly from a good-looking roof photo taken at a distance.
## Separate installation appearance from test results
Ask the trade which tests or checks applied to the scope and who performed them. Request the relevant records. Confirm that the job, area, date, and result match the project being presented.
[Raleigh's inspection-defect guidance](https://raleighnc.gov/permits/services/failing-inspection-residential-projects) includes missing plumbing tests and missing or incorrect duct-leakage documentation among its subjects. Ask for records as well as photos of those items. Do not treat a photographed gauge or finished grille as the record itself.
PNNL’s [duct-leakage testing guide](https://basc.pnnl.gov/resource-guides/duct-leakage-tests) describes a duct-blower test under an identified testing protocol. Ask the rater which system and work stage the supplied result covers.
Check whether a result applies to the whole scope or a defined part. Ask about corrections and later changes. If a record is unclear, ask the responsible professional to explain it. Do not interpret a test photo from memory.
Use [the rough-in photo workflow](/guides/photograph-before-it-is-covered/) to request better connected documentation on future jobs. It keeps capture and approval as separate tasks.
## Request the actual inspection status
If a caption says “approved,” ask which approval it means. Request the record and confirm the scope it covers. Keep ready-for-inspection, requested, failed, corrected, and approved stages distinct.
Ask the permit holder about unresolved items and any later required inspections. Do not turn one recorded approval into a promise about all work in the project. Confirm the applicable local process with the agency.
If the approval record is missing, leave the approval claim unconfirmed. You can still assess the visible photo while keeping that question open. Ask who can provide the answer and what evidence will resolve it.
Avoid requiring a company to publish sensitive permit records to prove a point. Arrange a private review with permission. Redact client information as appropriate for that conversation.
## Check credentials outside the gallery
For applicable NC GC credentials, the [NC Licensing Board for General Contractors](https://www.nclbgc.org/faq-consumers/) provides a license-search path. Use the correct business identity and ask the board about questions concerning scope or status.
Keep insurance and staffing questions separate from photo quality. Ask the appropriate employer, insurer, or agent about current coverage. Confirm the crew, start conditions, and responsibility for the actual job with the company.
A photograph from an earlier project does not establish today's facts. Record when you checked the evidence. Repeat a time-sensitive check when the status may have changed before work begins.
Use a private check sheet to record the source, date, identity, answer, and unresolved question. Do not write “verified” across the whole firm because one item has an answer.
## Ask a reference about the project shown
Choose a reference from similar work. Ask what they personally observed, which scope they worked with, and when. Get permission for the conversation and respect the client's privacy.
[David Weekley's vendor form](https://vendor.davidweekleyhomes.com/Home/SignUp) requests work-reference company and contact details as a separate subject. Follow the actual onboarding process of the builder involved. A gallery is not a replacement for a requested reference.
Use these proposed questions:
- What work did this company perform on the project?
- Who communicated when scope or timing changed?
- How did the handoff to the next trade work?
- Which corrections or return visits did you observe?
- What should I confirm about a comparable new scope?
Do not ask the reference to guarantee future performance. Ask them to stick to what they experienced. See [endorsements versus reviews](/guides/endorsements-vs-reviews/) for evaluating public recommendations.
## Check the evidence against your next job
Write down the proposed scope, relevant evidence, and open questions. A sub can have a strong project example that does not match your job. Ask what changes for your assembly, site conditions, or handoffs.
For each unanswered question, name the person or record that can answer it. A designer answers a design question. The trade explains its scope. The agency or issuer answers status questions within its authority.
Do not demand more photographs when the missing answer is a current document or agreement. Ask for the right evidence. Use the images to guide a focused conversation about the work.
## Where Cercha fits
The Cercha app brings portfolios, builder and sub endorsements, credential badges, and Messages into professional profiles. Use them to identify candidates and questions for follow-up. Its coverage disclosure directs users to verify with the employer or insurer, so keep current coverage checks separate from the gallery.
