The eleven questions
None of these needs technical knowledge from you. They need a specific answer from them, and a shop that gives eleven specific answers is almost always the right shop.
Ask these before you leave a deposit
- Which film line, by name? Brand alone is not an answer: most manufacturers sell a dyed, a carbon and a ceramic line under the same badge.
- What shade on each window, front, rear and quarter glass? Write the numbers down.
- What is the film's visible light transmission, and what does the law where I live allow? Ask them, and check your own state or province regulator too, because limits differ and change.
- What does the manufacturer warranty cover: bubbling, peeling, colour change? For how many years, and is it transferable?
- What does your installation warranty cover, and for how long?
- Is removing my old film included, and what does it add if not?
- Is the windshield or visor strip in this price, or extra?
- How long will the car be here today?
- How long until the film is cured, and when can I roll the windows down?
- What should I expect to see in the first week, and at what point should I call you?
- If I am not happy with a window when I collect it, what happens?
Three things to look at
Ask to see a finished car, and look at these three places rather than at the car as a whole. They are where a rushed install shows.
- The edges. Film should sit right to the edge of the glass with a consistent, tiny gap, not a wandering one. Ragged or uneven edges are a knife on glass rather than a pattern.
- The rear window. It is the hardest piece in the car: a big, doubly curved pane with defroster lines. If the rear window is clean, the shop can fit film.
- Contamination. Dust specks under the film are the one fault that never improves. A few are normal in any environment; a constellation is a dirty bay.
About the legal question
How dark you may legally go is set where you live, not by the shop and not by this page. Limits differ by state and province, they differ between front side windows, rear side windows and the windshield, and they change.
So ask the shop what they fit locally, and check your own regulator before you commit to a number. A shop that knows the local limits and volunteers them is a good sign; one that shrugs and says nobody checks is telling you what kind of shop it is.
What the percentage itself means, and how each shade reads at night, is on what tint percentage to get and in vlt meaning.
After the install
The single most common way a new tint job goes wrong is a window rolled down too early. Film is not bonded when you drive away; it is wet, and the water has to leave through the film.
That means haze, tiny water pockets and sometimes small bubbles for the first days, and it means leaving the glass alone. The published waits are on when can you roll windows down after tint and the whole timetable is how long does tint take to cure.
Published prices for the job itself, by film type, are on window tint cost.

Questions people ask
What should I ask a tint shop before booking?
The film line by name, the shade per window, both warranties and their terms, whether old film removal is included, how long the car will be there, and when you can roll the windows down.
How do I know if a tint shop is any good?
Look at a finished car: the edges should be consistent, the rear window should be clean and flat, and there should be very few dust specks under the film. The rear window is the hardest piece, so it is the honest test.
Should the shop tell me the legal tint limit?
A good one will know the limits where they operate and volunteer them. Check your own state or province regulator as well, because limits differ between windows and change over time.
Are bubbles after tinting normal?
In the first days, usually yes: the adhesive is still releasing water and small pockets and haze are part of curing. Bubbles that are still there after a few weeks, or that grow, are an adhesive or contamination problem to take back to the shop.
