Here’s our guide on what not to do after a windscreen replacement, followed by some essential maintenance tips to keep your glass in top condition.
Getting a new windscreen fitted is an important step in keeping your vehicle safe and roadworthy. Your windscreen isn’t just a piece of glass — it plays a crucial role in the structural integrity of your car, supporting the roof in case of a rollover and helping airbags deploy correctly.
A properly installed windscreen ensures clear visibility, protects you from the elements, and contributes to your overall driving safety.
However, the work doesn’t end once the glass is installed.
The first few days after replacement are particularly important. The bonding process needs time to stabilise, and small mistakes — like washing the car too soon or slamming the doors — can affect how well the windscreen sets in place.
In addition, consistent care over time will help maintain both the look and strength of your new glass, saving you money on unnecessary repairs in the future.
Below are some key points to help you protect your investment and make sure your new windscreen performs exactly as it should.
Windscreen Replacement Aftercare: What Not to Do
Even though modern adhesives and fitting methods are incredibly reliable, your new windscreen still needs a short settling period to reach its full strength. During this time, there are a few things you should avoid to ensure the best possible results.
1. Don’t Wash Your Car for 24–48 Hours
Avoid taking your vehicle through a car wash or washing it yourself for at least 24 to 48 hours. The sealant used to bond your new windscreen needs sufficient time to cure properly.
Depending on the weather and humidity, it can take between 22 and 48 hours to fully bond — in addition to the minimum safe drive-away time advised by your technician.
Washing your car too soon can compromise this seal and cause leaks or poor adhesion.
2. Don’t Slam Your Car Doors
It might seem harmless, but slamming car doors creates pressure inside the cabin that pushes outward — directly towards the freshly installed windscreen.
Until the adhesive has cured completely, this pressure could weaken the seal or even cause small shifts in the glass alignment.
Try closing your doors gently during the first couple of days after installation.
3. Don’t Skip ADAS Calibration
If your vehicle is equipped with ADAS (Advanced Driver Assistance Systems) — such as lane departure warning or automatic emergency braking — calibration is mandatory after a windscreen replacement.
If you had your glass fitted elsewhere and were told calibration isn’t needed, that’s incorrect.
Any car with a windscreen-mounted camera requires recalibration to ensure all safety features function as intended.
At UK Car Glass, our technicians are fully trained in ADAS calibration and will always ensure your system is recalibrated to manufacturer standards.
Once you’ve made it through the first couple of days after your windscreen replacement, the most critical settling period is over — but looking after your windscreen shouldn’t stop there.
Good long-term habits will help you keep your windscreen clear, strong, and safe for years to come.
Just like any other part of your car, a little regular attention goes a long way in preventing costly issues down the line.
Below are a few simple maintenance tips that can help you extend the life of your new windscreen and keep it looking as good as the day it was fitted.
Windscreen Maintenance Tips
Your windscreen faces a lot on a daily basis — temperature changes, road debris, flying stones, and even wiper blade friction. Over time, these small stresses can add up and affect both visibility and safety. The good news is that with a few simple maintenance habits, you can significantly extend the life of your glass and keep it performing at its best.
These tips are easy to follow, take only minutes, and can save you from unnecessary repairs or replacements in the future.
1. Inspect Your Windscreen Regularly
Just like checking your tyre pressure, make it a habit to inspect your windscreen from time to time. Spotting small chips or cracks early can save you from a costly replacement later.
If you notice a new chip, it won’t be covered under warranty, as it’s caused by an external factor beyond our control.
The best immediate action is to cover the area with a piece of clear tape to keep out dirt and debris — this will improve the chances of a successful repair.
2. Keep Your Windscreen Clean
It might sound obvious, but it’s especially important during the colder months.
If you leave your car parked overnight with a dirty windscreen, the dirt can freeze along with the moisture on the glass.
The next morning, when you scrape off the ice, you risk scratching your brand-new windscreen.
A quick wipe before parking can go a long way in protecting it.
3. Practise Defensive Driving
Keep extra distance from lorries and other vehicles that may kick up stones or debris.
Drive slowly on newly resurfaced roads to reduce the risk of flying objects damaging your windscreen.
Even with careful driving, chips can still happen — but by being mindful and proactive, you minimise the risks that are within your control.
