Common questions about replacing a car side window
-
How much does it cost to replace a side window?
The price depends on the vehicle’s make and model, but if your insurance policy includes glass cover, in most cases the cost is €0 for you—we handle everything directly with your insurer.
-
Can I drive with a broken side window?
It’s not recommended. It poses a safety risk, reduces visibility, increases the chance of theft, and you could even be fined.
-
Can it be repaired, or does it need to be replaced?
Unlike windscreens, side windows can’t be repaired. They must be replaced because tempered glass breaks into small pieces upon impact.
-
How long does it take to replace the window?
In most cases, we can do it the same day we receive the glass in the workshop. Thanks to our logistics hub, we can deliver it within 24 hours anywhere in Spain.
-
What about the broken glass inside the car?
Our technicians perform a full interior cleaning to remove any shards left on the seats, floor, or inside the door mechanisms.
-
Can I leave the car and pick it up later?
Yes, you can leave your vehicle at the workshop and we’ll call you when it’s ready. You can also book online and we’ll give you an exact time to avoid waiting.
-
Can I come without an appointment?
We recommend booking an appointment to guarantee immediate availability of the glass, but you can also come by and we’ll assist you as soon as possible.
-
Do you also check the window mechanism?
Yes, we take the opportunity to check that the manual or electric system is working correctly. If we detect any issues, we’ll let you know.
The structural importance of your car’s side windows
More than just a window: a key element in your vehicle’s safety
Although they may seem like secondary elements at first glance, car windows play a much more significant role —in every sense— than we usually imagine. Especially structurally, as they’re an active part of the vehicle’s bodywork.
The windscreen supports the roof and is essential for proper airbag deployment, while the side windows also strengthen the car’s structure. In fact, automotive glass can account for up to 30% of a vehicle’s structural resistance. So when one breaks, it’s not just an aesthetic or comfort issue — it’s a matter of safety.
What type of glass is used in car side windows?
Tempered glass: safety through controlled breakage
Side windows are made of tempered glass, a material specifically designed to shatter into many small, rounded pieces upon impact. This helps prevent serious injuries to passengers, unlike regular glass.
However, because of this shattering property, a broken side window cannot be repaired—only replaced. That’s why trusting qualified professionals makes all the difference.
Your car’s windows do more than you might think
The glass in your car plays a more important role than it may seem at first glance. In fact, the word “weight” is key here. While the windscreen supports the roof of the vehicle, the side windows also contribute structurally. Altogether, car windows can account for around 30% of the vehicle’s structural strength.
Considering their importance, it’s highly recommended to rely on experts when replacing a damaged window. Ralarsa is one of the most experienced companies in this field across Spain. As specialists in automotive glass, it’s one of our core services.
If your car insurance includes glass coverage, you won’t have to worry about anything. With no upfront payment, Ralarsa handles all communication and paperwork with your insurer. And if you don’t have coverage, we still offer some of the most competitive prices on the market.
Ralarsa provides this service either at one of our 250+ workshops across Spain or via mobile service wherever your vehicle is parked—just request an appointment in advance.

I made an appointment for one day and two days later they called me to apologize that they couldn't see me because the staff was on sick leave and they made another appointment for me and everything went very well.
I've been renting cars for 20 years, and the service and speed are truly exemplary. I've had to go twice in one week, and the speed was impressive. They even let me use a part of their office to continue working while they installed the glass.
That's a pleasure.
Kindness, good work, speed. Everything perfect.
Excellent service and speed. I dropped it off today at noon and it's already ready. The gentleman who served us was also very kind and attentive.
I'm very happy with the service I received at Ralarsa. Pedro replaced my car's windshield, and I couldn't be more satisfied: he was fast, very friendly, and the work was perfect. You can tell they're windshield specialists, and that inspires a lot of confidence. The friendly, personal approach is also very much appreciated. It's not a general repair shop, but rather a center specializing in windshield repair and replacement, and it shows in the quality of service. I definitely recommend it.
