Window tint replacement is due when the film turns purple, bubbles, peels at the edges, goes hazy or stops holding back the heat. Each of those means the film or its glue has broken down, and it won’t come good again. The fix is to strip it back to bare glass and fit new film.
Cory has been fitting and stripping tint around Brisbane since 2008, and tired film nearly always tells the same story. It’s usually a ute with a rear window so blistered the driver can’t see the car behind, or a family wagon where the back windows have gone a bruised purple after a few summers in the school car park. If that sounds like your car, our car window tinting service covers stripping the old film and fitting new. Here’s how to tell if yours is due.
Signs it’s time for window tint replacement
Walk around the car on a sunny morning and check each window from outside and inside.
- The colour has gone purple. Cheap dyed film gets its colour from dye, and UV breaks that dye down. What’s left is a purple or brown cast, and film in that state lets far more heat through than it did new.
- Bubbles or blisters have appeared. Pockets of air or moisture mean the adhesive has let go of the glass. The rear window usually goes first because it sits flatter and cops the full afternoon sun.
- The edges are lifting. Peeling often starts along the top of the front windows, where the glass slides through the rubber seal every time you wind it down.
- The glass looks hazy or wavy. Cloudy or rippled film is easiest to spot at night, when oncoming headlights flare across it. On the front windows it can blur your view of the side mirrors.
- It’s scratched. Seatbelt buckles, dog claws and tools sliding off the back seat all leave marks. Film can’t be polished like paint.
- The heat is back. If the steering wheel is too hot to hold after a day in the car park again, the film has stopped doing its job, even if it still looks dark.
- It’s darker than the law allows. Second-hand cars often come with a previous owner’s film. If it’s below the legal limit, it’s a defect notice waiting to happen.
How often should tint be replaced?
There’s no set schedule. Tint should be replaced when it shows the signs above, not because a certain number of years has passed. In Brisbane, budget dyed film often starts fading or bubbling within three to five years. Good carbon and ceramic films are built to last far longer, which is why ours carry a lifetime manufacturer-backed warranty.
A few habits shorten tint life on any car:
- Parking in full sun every day, especially facing west at work.
- Cleaning the glass with ammonia-based products, which soften the adhesive over time.
- Running a pressure washer along the window edges.
- Winding the windows down in the first few days after fitting, before the film has cured.
Can you put new window tint over old tint?
No. New film needs bare, clean glass to bond to. Laid over old tint, it traps every bubble and patch of haze underneath, and the new adhesive grips failing film instead of glass. Two layers can also drop the window below Queensland’s legal limit without you noticing. The old film has to come off first.
What window tint removal involves
Removal is the slow part of the job. We strip the old film, clean off the adhesive and fit the new tint as one job. The film is softened with heat or steam and peeled off in as few pieces as possible, then every trace of glue comes off the glass. Sun-baked film comes away in small flakes, so an old purple rear window takes far longer than a front window that lifts off in one sheet.
The back window needs the most care. The demister lines run across the inside of the glass, right where the film sits, and a razor blade will cut straight through them. The classic DIY result is half the film gone, the glue still there, and a demister that no longer clears the glass on a cold morning.
Is 35% tint legal in QLD?
Yes. In Queensland, front side windows can be tinted as dark as 35%, meaning at least 35% of light still passes through. Rear side windows and the back window can go to 20%, as long as the car has a mirror on each side. The windscreen can only have a narrow strip across the top.
There’s a catch worth knowing. The limit applies to the glass and film together, not the number printed on the roll. Most factory glass already carries a slight tint, so a film rated at 35% can meter darker once it’s fitted. Film also can’t be more than 10% reflective, which rules out mirror finishes. Our guide to Queensland window tinting laws covers the detail.
Replacement is a good time to fix tint that’s too dark. The Queensland Government requires a new safety certificate every time you sell a registered car, and tint below the limit is the kind of defect that holds up a sale.
How much does it cost to tint a car in Australia?
It depends on the car, the film and whether old tint has to come off first, so there’s no single national price. A small hatch in dyed film sits at the low end. A large SUV in ceramic film with old tint to strip sits at the high end. The only accurate figure is a quote on your car.
What moves the number:
- Size and number of windows. A dual-cab ute with a sliding rear window is a different job to a two-door coupe.
- Film type. Dyed film costs the least. Carbon and ceramic cost more and hold back more heat for longer.
- Removal. Stripping baked-on film and glue adds labour, especially on a rear window with demister lines.
Why cheap film costs you twice
Replacing failed tint means paying for removal and new film, on top of what the cheap job cost in the first place. A good install on cheap film is money spent twice.
That’s why we fit 3M and Ultraguard films, picked because they hold up in Queensland sun. 3M Crystalline, one of the car films we fit, blocks 99% or more of UVA and UVB on the manufacturer’s spec sheet. That counts for kids in the back seat with their arms against the glass for the whole school run. Cancer Council Australia advises people to protect their skin whenever the UV index reaches 3, and failed tint gives the back seat very little cover.
Glass Tinting Solutions was named the #1 Best Rated Window Tinting business in Brisbane Western Suburbs, QLD for 2026 by the Quality Business Awards. Cory still quotes and fits the work himself, and if a cheaper film will do your car fine, he’ll say so.
Window tint replacement FAQs
Does the warranty cover tint that’s gone purple or bubbled?
Yes, if it’s film we fitted and the fault is in the product. Our lifetime manufacturer-backed warranty covers film that peels, bubbles or discolours because of a product fault. Physical damage such as scratches isn’t a product fault, and tint another installer fitted sits under their warranty.
Can I remove old car tint myself?
Yes, on the side windows, if you’re patient. Steam and a plastic scraper work better than a hair dryer and a blade. Leave the rear window to a professional, because one slip with a blade cuts the demister lines.
Can I wind my windows down straight after new tint goes on?
No. Keep them up for the few days your installer gives you so the adhesive can cure. Wind them down early and the bottom edge can catch on the seal and start peeling.
