Are DIY Windshield Repair Kits Safe?

Just because windshield repair kits are typically inexpensive, does not mean they are a good solution or the safest option.  You don't want to mess around when it comes to repairing chipped or cracked windshield glass.  Having professionals like Glass America repair your vehicle’s glass is always the better choice.  Here’s why you should not use DIY windshield repair kits:

  • They cause more damage.  A windshield chip repair kit is only a band-aid solution.  In a worst-case scenario, they can spread the crack in the glass further.

When the outside temperature is too warm or cold, kits cause added friction. As the glass shrinks or expands, it rubs together, resulting in more damage.

  • Your warranty may be voided.  Did you know that by using a windshield repair kit, your warranty will be voided?  It’s likely mentioned in the fine print somewhere.  Sometimes it’s best not to take matters into your own hands!

  • The crack is too large.  Most DIY repair kits are only good for small, bullseye-like cracks and not longer ones. The resin-based formula of these kits isn’t meant to glue glass together.  Instead, it acts as a space filler that bonds the center, preventing further stress.  Once a windshield crack is larger than a quarter, you can’t patch it safely.  
  • Safety hazard.  Most windshield repair kits are for small pebble-sized damages.  When installed in a direct line of sight, it can reduce your visibility.  When they dry, they don’t always achieve a crystal-clear finish, solidifying instead and obstructing your view.  Not only that, but the vibration of your car could produce enough friction to shatter the glass.  This creates a terrifying situation for yourself and the drivers around you.  

It’s likely more affordable to replace your windshield.  Depending on your vehicle’s make, model, and weight class, replacing windshields can be surprisingly affordable. Many insurance companies will even cover your costs, partially or entirely, based on your policy.  They would rather pay to replace damaged auto glass than have it break during use.  Don’t waste your money on cheap and ineffective windshield chip repair kits - contact the professionals at Glass America instead.
