Check the completed work against the agreed scope, look through each treated window and raise questions while the installer can explain what you are seeing.
A useful inspection is calm and specific. It should not assume that every tiny feature is a failure or that every concern can be dismissed as normal drying.
Confirm the job first
Compare the invoice with the pane list and product choice. Are the agreed windows treated? Are the film and shade recorded correctly? Are any planned exclusions or boundaries clear?
If you do not understand an area that looks different, ask the installer to show it to you. A misunderstanding about coverage is easier to resolve with the written scope in hand.
Look through the glass in ordinary conditions
The IWFA's automotive inspection guidance uses natural daylight and views through the installation. This helps distinguish normal viewing concerns from an unusual close-up or extreme angle.
Use that as context, not as a reason to ignore a problem. Pay attention to what you notice from the normal seated position and around the vehicle.
Do not lower a newly treated window for inspection until the installer confirms that it is appropriate.
Check one window at a time
For each pane, ask yourself:
| Check | Useful question |
|---|---|
| View | Can I see clearly through the area I use? |
| Overall appearance | Is there an obvious concern I want explained? |
| Edges and boundaries | Does the finish match what was discussed? |
| Nearby trim | Is there any change that needs to be recorded? |
| Normal operation | Has any existing or new issue been identified? |
If a pane has a drying effect, ask what change is expected and when to review it. Do not assume you must make a final judgment about every temporary appearance at collection.
Describe, rather than diagnose
“An edge is lifting near the upper corner” is useful. “The installer used bad glue” is a conclusion that may not be supported.
Take a photo showing the location and write down when you noticed it. Ask the shop to inspect and explain the next step.
A close-up can document detail, but it should be paired with a wider view. That gives the person assessing the concern a better sense of its position and scale.
Do not turn a guideline into a guarantee
A published inspection guide does not determine every warranty, legal right or individual installation outcome. Your agreed scope and the applicable terms still matter.
Likewise, a shop should be able to explain why it considers an appearance acceptable rather than using “industry standard” as an answer to every question.
If you disagree, ask for the relevant criterion and a clear written response.
Leave with the follow-up plan
Keep the exact product, receipt, warranty and care instructions. Record who to contact, what photos to provide and when a drying concern should be reviewed.
The aftercare guide helps organize those details. The shop-responsibility guide explains who may be involved if a later problem needs attention.
A good handover leaves you understanding the work and the next step, even when one item needs a follow-up inspection.
