You’re staring at a crack in your house window, and you remember that kit you have for repairing your car windshield. Can you use the same stuff on your house window? Unfortunately, it’s not that simple. While the concept of fixing a crack might seem similar, car windshield repair and house window repair are different beasts.

Understanding the Difference: Car Windshield vs. House Window
Car windshields are made from laminated glass, which is essentially two layers of glass with a layer of polyvinyl butyral (PVB) in between. This construction makes them strong and prevents them from shattering into sharp pieces upon impact. A crack in your windshield is usually only on the outer layer of glass, allowing for repair with resin that fills the crack and bonds with the PVB.
House windows, on the other hand, are typically made from annealed glass or, less commonly, tempered glass. These types of glass are treated differently during manufacturing and don’t have the PVB layer.
- Annealed glass is cooled slowly to relieve internal stresses, making it easier to cut. However, it breaks into sharp shards when it does fracture.
- Tempered glass is rapidly cooled, making it stronger than annealed glass. When broken, it crumbles into small, less dangerous pieces.
Neither annealed nor tempered glass can be repaired effectively with the resin used for car windshields.

Why Car Windshield Repair Doesn’t Work on House Windows
The resin used in car windshield repair kits is designed to bond specifically with the PVB layer in laminated glass. Without this layer, the resin won’t adhere properly to a house window, leading to several issues:
- Weak Bond: The resin will likely not fill the crack completely or create a strong enough bond to hold the glass together.
- Visible Repair: Unlike the nearly invisible repairs possible on windshields, the resin will be much more noticeable on a house window, especially if the crack is large.
- Structural Integrity: House windows are designed differently than car windshields. Applying resin might not address the underlying issues that caused the crack, potentially compromising the window’s structural integrity.
When to Repair or Replace a House Window
Small cracks in a house window might seem like a simple fix, but using car windshield repair methods is not the answer. In most cases, a cracked house window requires professional replacement. Attempting DIY repairs with inappropriate materials can worsen the damage or pose safety risks.

Seeking Professional Help
When dealing with a damaged house window, it’s best to consult with a qualified glazier. They can assess the damage and recommend the most appropriate course of action, whether it’s a complete window replacement or other potential solutions.
Remember, while it’s tempting to use a quick fix, ensuring the safety and structural integrity of your home is paramount.
FAQs about Car Windshield Repair and House Windows
Can I use superglue to fix a crack in my house window?
No, superglue is not designed for glass repair and can cause further damage or create a messy, ineffective fix.
Is there a special resin for repairing house windows?
While some products are marketed for repairing small cracks in house windows, they often come with limitations and might not provide a lasting solution.
How much does it cost to replace a house window?
The cost varies depending on the size, type, and style of the window, but it’s generally more expensive than repairing a car windshield.
