Jason is the guy to go to, exceptional service and even better work provided. My head lights look brand new worth every dollar, it was a fraction of the price if I were to just get new head lights.

Jason at Guardian did a great job repairing my windshield. I had a crack that was about 2 inches in each direction radiating from the divot hole. I called a few windshield repair places and they all said it couldn't be fixed and I'd need a new windshield, and for my car that also means a new calibration, which…

This was the best experience. I went to their new Belmont location (which is 5 mins from my house!) and I was in and out in 30 mins. Also called yesterday and they got me in today.

Flawless! Jason had availability to fix our smallish rock chip (under 1") the next day. His process was smooth, communication was clear, he was friendly, and the repair was excellent. Highly recommended. (My phone couldn't take a good "after" shot because there was no crack to focus on!)
Highly recommend Guardian Windshield Repair & Headlight Restoration for professional headlight restoration in the San Mateo County area!
Jason & his team were professional, knowledgeable, and demonstrated excellent attention to detail. The headlight restoration service made a noticeable difference in the appearance and clarity of my headlights & the grille emblem!
I’ve included before-and-after photos so you can see the results of the restoration. It’s a great example of how professional headlight restoration can improve cloudy, faded, or oxidized headlights without the expense of replacing the entire headlight assemblies.
Excellent workmanship and customer service!

Jason is the guy to go to, exceptional service and even better work provided. My head lights look brand new worth every dollar, it was a fraction of the price if I were to just get new head lights. He saved me the trouble and now my head lights actually light up the road at night! I cant express enough of the craftsman ship him and Andre display, they are masters of their craft. You will not be disappointed with their service as well as the quality of work. Service was so good I am kind of disappointed my headlights will be clear like this for years to come, I would come back annually just to have great service like that again!

Jason at Guardian did a great job repairing my windshield. I had a crack that was about 2 inches in each direction radiating from the divot hole. I called a few windshield repair places and they all said it couldn't be fixed and I'd need a new windshield, and for my car that also means a new calibration, which meant $800-900 total. Jason repaired the problem for much less and avoided any risk from a recalibration. He was upfront when assessing the problem about whether he could do it or not and what it would look like after completion. You will need to go to his garage in Belmont (he no longer does mobile services) but it's well worth it if you want to avoid a full windshield replacement.

They did a resin repair on a windshield chip and it’s way better and less noticeable than I anticipated. Was very affordable and comes with a lifetime warranty. The owner Jason was super nice too. I hope you don’t need the service, but if you do this is definitely the place to go. I’d give it 10⭐️ if I could

The shop itself is brand new, extremely clean, and conveniently located.
I would highly recommend Guardian Windshield Crack Repair and Jason and I’ll definitely be back if I ever need another repair.

Had the best experience with Jason from Guradian windshield repair. Was very communicative even when I was lagging in responding. He was very professional & very informal & prideful of his work which I loved & absolutely respected. He reassured me if the job wasn’t completely fixed or didn’t go as planned he’d accommodate something for me at the end. I was absolutely satisfied with the outcome on my headlight restoration & he broke it fully down in detail. He was kind enough to offer me a discount due to old headlights & he also fixed a chip on my windshield as well while he was there. Couldn’t be happier with the service especially the great price he offers. 10/10 experience highly recommend him & his work.
