Broken side mirrors - directions how to fix them

To have a minimal cost when repairing broken side mirrors of a vehicle you can do the job by yourself.


What to Use: replacement glass, silicone – 3 oz. tube, masking tape, putty knife.

  • Buy replacement glass from an auto parts shop. In case they don’t have it in store, you will have to order it and wait few days until it arrives. It should cost around 12-30 dollars.
  • Take off all the broken pieces that remained from the old mirror. Use the putty knife to scrape off all glue or adhesive. Make sure that the surface is properly cleaned before moving to the next step.
  • Take an economy or generic brand silicone – blue, black or clear – as this type of silicone hardens properly, unlike the ultra silicone which is more expensive. Put 4-6 teaspoon sized blobs on the backing plate.
  • Take the new mirror and mount it carefully against the backing plate. Press gently. Use 3-4 strips of masking tape to hold the mirror in the position that it was put. Attach the tape to the surface of the mirror and then  stick them to the edges of the mirror holder. For the silicone to cure and harden properly leave the tape for almost 4 hours.
  • Use a window cleaner to remove the tape and to clean the glass. Now, the only thing left is to adjust the mirror and to drive safely.
