The Top 3 Signs Windshield Sealant May Need To Be Applied Around Your Windshield

A product called sealant is used to seal off the crack between your windshield glass and the gasket, or framed part of the auto body, that the glass sits in. However, as your car sits out in the sun or is exposed to hot and cold temperatures, this sealant can wear away. When this occurs, you may need to have more sealant applied to hold the windshield firmly in place and keep moisture out. Here are three of the top signs that windshield sealant may be worn and may need to be reapplied. 

1. Water is Seeping In Through the Edges of the Windshield 

One of the top signs that the sealant that seals the gap between your windshield glass and the gasket is water or moisture present near the edges of your windshield. When the seal is intact, outside water cannot seep in through your windshield. However, when the seal is wearing off, there may be small gaps that are starting to emerge between the glass and the gasket. This allows water to seep in. You may notice the water when it rains or after sprinklers hit your car. If you suspect this is happening, spray your windshield area with a hose and see if you can see or feel moisture on the inside of the windshield. If you can, sealant needs to be reapplied. 

2. You Notice Rust Near the Windshield

In some instances, moisture may be seeping in through the windshield, but you may never actually see the water. Cars are made from metal, and when metal gets wet, it begins to rust. As such, another sign that your sealant may be wearing off around the windshield is the appearance of rust around the inside edges of the windshield. If you notice rust is present, you want to have the rust removed, and sealant reapplied as quickly as possible. 

3. Your Windshield Shakes and Rattles When Driving

While the primary purpose of windshield sealant is to seal off the gap between your windshield glass and the gasket to keep moisture out, the sealant also helps to hold the glass firmly in place. When the sealant begins to wear, you may notice that your windshield begins to shake or rattle as you drive. This may be more prevalent when you hit a pothole or are driving on a rough road. If you see the windshield shaking, rattling or bouncing, you may need to have the sealant reapplied. 

Installing sealant around a windshield is a challenging task. This is not a do-it-yourself project that the average person should attempt to undertake on their own. If you notice any of the above signs that are indicative of sealant that is worn, contact an auto glass service today to schedule an appointment to have sealant reapplied.
