How to fix a leaking car windshield DIY video

Buy the windshield glass sealant here: amzn.to/45dcWHM
Today I will show you how I repaired my windshield that was leaking into my car. When it rained we would get a bunch of water into the bottom of our car by our feet. We placed a little product to close up the leak in our windshield. If you have any questions, leave comments below and we would love to answer them.

I really appreciate your diagnosis and proof. Recommend masking the areas you don’t want the sealant to cover with yellow frog tape. This will allow you to push the sealant into the gaps more aggressively and tool it to a smooth finish. Immediately remove the tape before the sealant skins over.

So how did it go?

[@Nickm32797]

Hey guys, it went great! I put plenty of the sealant on, and even tried the jug of water trick as an experiment and it worked like a charm! Now my electronics won’t prevent me from starting the car, cheers 🍻

[@danielhill4446]

Looks exactly like one of my caulk jobs.

[@bloomerb4162]

Needs to be in caulk gun so you can force it in small areas. That probably won't work or last very long.

[@BigAl-1]

Thanks for the suggestion. Luckily it has been holding strong for almost 1 year.

[@bloomerb4162]

@BigAl-1 I just made a big mistake. Leak in truck and I found some permatex flowable silicone still in package, in garage. I knew about expiration with this kind of stuff but used it anyways. So after 3 days it was still tacky. Looked up date code and it expired in 2007

[@GenaralZod]

My Altima leaked on the driver side. i sealed it the same as you did. I hope it fixed it.

[@BigAlRepairs]

I hope so too! Let us know how it worked for you. THanks!

[@BigAl-1]

Please let us know how it turned out.

[@GenaralZod]

@@BigAl-1 It did not fix it. I have to try something else.

[@consumer1073]

would this work for a decent sized gap in the front part where you first poured water in the beginning of the video? mine has a pretty big gap where the rubber lining has separated revealing the edge of the glass

[@chrismahfouz6837]

Best to go ahead and have the windshield removed cleaned and resealed. Can get through the smallest of spaces and before you know it, you’ve went around the whole windshield and it still leaks.

[@BigAl-1]

Thanks so much for the suggestion. That is always an option. We were trying to save a few dollars. Best of luck with your next DIY project and hopefully you subscribe to Big Al Repairs.

[@timothyhua1477]

Remember when you poured water at the bottom off the windshield you will never find leak down there because water can never travel up. If you have water inside the car when you do that, that means your drain hole is clogged.

[@XDMIIIIIIIII]

How much is that roughly for normal brand cars

[@BigAl-1]

It depends on what kind of car you have. I paid around $400 for the last windshield that I had replaced.

[@evan135]

Same exact issue with me 13 civichad the windshield replaced by safelite because insurance covered it, about 5-6 months later i noticed the carpet was soaked, turns out it is leaking in the top corner of the inside seams above the headliner. Safelite tested it twice and said it wasnt the windshield but im not buying it, im taking it to a mom and pop auto glass shop to have the pull the glass and re seal it, i also was thinking it was the seam sealer in the roof channels but it still leaks

[@BigAl-1]

Thanks so much for sharing your experience. It sounds like you have the same problem that I had. Best of luck and please give us an update. I’m curious how much they will charge to re-seal your windshield. Hopefully you subscribe to Big Repairs.

@@BigAl-1 well ended up fixing it myself, used seam sealer instead of silicone this time, had to put two layers on along the top corner of the windshield and about an inch down the down of the windshield

[@lindseylambson9669]

Why would a windshield be leaking like that?!

[@BigAlRepairs]

thanks

[@user-ew5pu8yz7d]

Because the windshield in this car was changed at some point and proper installation methods weren’t followed causing the bond to not correctly adhere between the glass, urethane and body. They likely didn’t clean, prep or prime. This is why you should always choose a certified auto glass shop, make sure and read their reviews. I’m an auto glass shop owner/operator and fix hack work like this everyday. I do thousands of cars a year and none of my installations leak.

[@KameronKinser]

Thank you for sharing this was super helpful!!

[@pkginbro6456]

It could also be a dried out seal to, it’s not always because of a windshield change. We had it happen to our factory windshield.

[@timothyhua1477]

Man you doing it all wrong and making it look like crap after awhile. Proper way to do it is remove the inside pillars and cock urethane along the seal and pressed it in and smooth it out with your finger.

[@user-ew5pu8yz7d]

Just call a professional auto glass guy that will fix it the correct way. This is a temporary fix at best.

[@BigAlRepairs]

This saved us over $100 and worked great until we could get a new windshield. Thanks for the comment

[@chrismahfouz6837]

Water intrusion and the condensation that will follow will cost a LOT more. Electrical damage being a prime danger!

[@Boinks]

If you do this to your vehicle and bring it into any larger glass replacement shop in the future they will not touch your window. do this at your own risk. But my shop will turn you away

[@BigAl-1]

Interesting. Maybe you can explain why the windshield leaked. Poor installation?
