The Basics of Window Repair

One of the most common instances in car repair is addressing cracks in a windshield or replacing an entire window. It is for this reason that an entire car repair industry has been built around glass repair services.

Garages boast expertise and offer a warranty for their work, yet as repairing a broken or damaged window can sometimes cost less than an insurance premium, many owners choose to perform the repair themselves.

Here we examine the do-it-yourself steps necessary to remove and replace car glass.


A minor crack in a windshield can often be repaired with do-it-yourself epoxy and resin kits. This can be performed in a matter of minutes and the results can be a nearly flawless finished product.

Resin Application - Step by step:
  • Clean the surrounding surface area.
  • Apply the suction cup apparatus supplied with the product.
  • Insert the resin from the syringe.
  • Allow any bubbles to rise to the surface and the resin to dry.
  • Scrape off any excess material with a razor.

However, if the crack is more than six inches in length or obstructs the driver's line of sight, the entire windshield will need to be replaced. The rubber gasket around the periphery will be removed and the specific car glass manufacturer should be contacted to provide a replacement. The unit will then be put back in place and a new gasket will be used to provide a secure attachment as well as to prevent any rain water from entering.

Car Glass Repairs for Doors and Rear Windows

Repairing these areas is notably different, for side and rear windows are heat tempered. Thus, they will break in a catastrophic fashion into the characteristic cubes that are often seen. So, the first obvious step is to clean up all of these tiny pieces as although they will not cause grievous bodily harm, they can still produce nasty cuts.

Next, the specific part needs to be ordered. Most windows for main market vehicles are easy to find and glass replacement warehouses may have the necessary window on-hand or at the very least provide a referral to the relevant dealer who will. There are other times that visiting a local used car dealership or a dump can be beneficial; replacements found here will cost substantially less than through a dealer.

After the correct car window is obtained, the next step is the replacement itself. In the case of a rear window, the process is similar as it is with windshield repair; the damaged section is removed along with the gasket. The new window is put in place and a new gasket is attached.

Windshield and rear window repair - Step by step:
  • Epoxy may be used to fix small cracks in windshields.
  • Larger cracks or complete breakage will dictate the need to order a replacement part.
  • The window and surrounding gasket are removed.
  • The replacement is installed and a new gasket is attached.

However, door window repair can be a bit more challenging. The door's inner panel must first be removed. This can be done with the help of the vehicle's owner's manual. For power windows, remove the power plug found inside the door before any servicing. Remove the lower window seal, as this will make it easier to install the new window. Slide the replacement car window down vertically until it rests firmly on the top track of the raising and lowering mechanism. Bolt the piece into place into the track (there will be a bolt that held the previous window). Plug back in the door window's power supply and before reinserting the inner panel, turn on the ignition and make certain that the window is able to be raised and lowered without any difficulty or obstruction.

Door window repair -Step by step:
  • Remove the inner panel of the door.
  • Disconnect the window's power supply.
  • Temporarily remove the top rubber seal located where the window will rise from the door.
  • Insert the new piece.
  • Bolt the window into place into the track.
  • Reconnect the power supply.
  • Make certain the window has a free range of motion and is not loose before reattaching the inner lining and top rubber seal.

It is obvious that this process is anything but simple and as many vehicles have become more advanced in recent years, many situations dictate that a garage may be the best and safest option.
