It could be cheaper to replace your own windshield if you have the necessary tools, skills, and knowledge to do it. However, it’s important to keep in mind that the actual cost can vary depending on the make and model of your vehicle, as well as the cost of the windshield itself. In many cases, windshield replacement cost could be the most expensive part of the job.

In terms of labor, doing it yourself certainly eliminates the cost of hiring a professional. However, you should also consider the value of your own time, as the job can be quite time-consuming, especially for someone who is not experienced.

It’s also crucial to note that windshield replacement isn’t an easy task. It requires specific tools, knowledge, and precision to ensure that the windshield is installed correctly and safely. Incorrect windshield installation can lead to leaks, wind noise, visual distortion, and even risks in case of a collision because windshields play a vital role in the structural integrity of a vehicle.

Furthermore, if your vehicle has special features like a head-up display, rain sensors, or advanced driver assistance systems (ADAS) like lane departure warning or automatic braking, then it will need to be calibrated after the windshield replacement. This process requires specialized knowledge and equipment that most DIY-ers do not have, so it would be safer and more cost-effective to have a professional handle it.

Reasons why should a professional handle your vehicle’s windshield replacement

There are many reasons why you should have a professional handle your vehicle’s windshield replacement. Here are some of the most important:

Experience and Skills

Professional windshield replacement services have trained technicians who have worked on a variety of car models. They possess the expertise and the correct techniques to ensure a perfect installation.

Quality Materials

: Professionals use high-quality materials, such as top-quality adhesives and glass, that meet or exceed the original equipment manufacturer (OEM) specifications. This helps ensure the durability and effectiveness of the replacement.

Guarantees and Warranties

: Many professional windshield replacement companies provide warranties on their work. This means if anything goes wrong within the stipulated warranty period, they will fix the issues free of charge.


: The windshield contributes to the structural integrity of your vehicle, especially in the event of a rollover accident. A poorly installed windshield could pop out or shatter, endangering the vehicle’s occupants. Professionals will ensure it is properly installed to maximize safety.

Proper Tools

: Professionals have specialized tools to handle windshield replacement efficiently and correctly. These tools are typically not available to a non-professional, and improper handling can lead to further damage to the vehicle.

Adherence to Regulations

: Professional services are familiar with and adhere to the local safety standards and regulations. This ensures that your vehicle’s windshield is replaced in a legal and appropriate manner.

Convenience and Timesaving

: A professional can replace your windshield more quickly and efficiently than an untrained individual. They often offer services like mobile windshield replacement, where they will come to your location to perform the replacement.

Insurance Claims

: If you have comprehensive car insurance, it might cover windshield replacement. Professionals usually handle the insurance claim process, reducing the hassle on your part.

Disposal of Old Windshield

: Windshields are large, heavy, and made of glass, making them difficult and potentially dangerous to dispose of. A professional service will handle this task as part of the replacement process.


: Modern vehicles often have Advanced Driver Assistance Systems (ADAS) that can be in or around the windshield. When a windshield is replaced, these systems may need to be recalibrated. Professionals have the knowledge and equipment to handle this.

DIY Windshield replacement: Pros and Cons

Replacing a vehicle’s windshield can have several potential outcomes, both positive and negative, depending on the quality of the replacement job. Here’s what can happen:

Positive Outcomes:

Improved Visibility: A new windshield can provide clearer visibility, which can be a major safety upgrade if your previous windshield was chipped, cracked, or clouded. Increased Safety: Modern windshields are designed to support the structural integrity of a vehicle during a crash. A new, properly installed windshield can help ensure that your vehicle’s safety systems perform as intended. Prevention of Legal Issues: In some jurisdictions, driving with a cracked or damaged windshield can result in fines or other penalties. Replacing a damaged windshield can help you avoid such problems.

Negative Outcomes

Poor Installation: If you don’t properly replace your windshield or if the replacement is done by an inexperienced installer, it can lead to problems such as water leaks, wind noise, or even a loose windshield that could potentially pop out during an accident. Incorrect Fit: Not all windshields are created equal. An improperly fitted windshield could lead to wind noise, leakages, or impaired visibility. Cost: Depending on the make and model of your vehicle, a new windshield can be expensive. Potential Damage: If not done carefully, the process of windshield replacement can potentially cause damage to other parts of the vehicle, such as the dashboard, trim, or paint. Sensor Malfunction: Many modern cars have sophisticated technology, including sensors, cameras, and other devices, embedded into, or located near the windshield for driver assistance systems. If these are not calibrated or reinstalled correctly after a windshield replacement, they might not function properly. Inferior Quality: If you replace windshield of lesser quality, then it could affect the vehicle’s structural integrity, safety, and performance over time.


So, while it may seem like you could save money by replacing your own windshield, it’s usually best to leave this job to professionals unless you have substantial experience with this kind of work. Mistakes could lead to more costly repairs down the line, or worse, they could compromise your safety. Insurance may also cover part or all the replacement cost, depending on your policy, which is another factor to consider.
