How To Repair Small Cracks In Your Wood Garage Door

by Harvie Simms

Wood garage doors are typically quite durable and will last many years before needing to be replaced. However, during this time, you may find that your garage door will develop small cracks as a result of extreme weather or exposure to moisture. The bad news is, these cracks can drastically impact the way your garage door looks. The good news is, repairing these cracks may be much easier than you think. In fact, most homeowners will be able to complete these repairs on their own by simply following the steps below.

Supplies You Will Need

  • Handheld sanding block
  • Fine grit sand paper
  • Clean paint brush (2)
  • Wood putty
  • Putty knife (appropriate size for the size of your cracks)
  • Wood stain or paint

Step 1: Clean The Damaged Area

Any dirt and debris will need to be removed before you can begin the process of repairing your garage door. In order to complete this task, simply use a handheld sanding block covered with fine grit sandpaper to sand the top layer off the entire area surrounding the crack. You will also need to sand inside the crack in order to remove any wood splinters or other debris that may be present. If you are unable to sand inside the crack due to its small size, the use of a rotary tool may allow you to easily reach deep inside the crack.

Once you have successfully sanded the entire area, use a clean paintbrush to clear away any sawdust or dirt that remains on the door's surface.

Step 2: Fill In The Cracks

Using wood putty, begin to fill in each crack one at a time. Be sure to reach the putty deep into the crack using an appropriately sized putty knife. Once the crack is completely filled, you can also use the edge of your putty knife to smooth the surface of the repair patch and remove any excess wood putty.

Your wood putty should be allowed to dry completely before moving on to the next step. While this process will typically take about one day, not all putties will dry at the same rate, so be sure to check your product packaging for exact drying times.

Step 3: Apply The Finishing Touches

Once your wood putty has dried completely, use a piece of fine grit sand paper to sand the surface of your repair patch until it is completely smooth. Once again, use your clean paintbrush to wipe away any sawdust that may remain on the door. Finally, apply a coat of wood stain or paint in order to protect the area from further damage and match the appearance of the repaired area to the rest of your garage door.

A Final Thought

While the repair process described above is extremely effective when repairing minor damage to your wood garage door, this process is not intended for major repairs. If your garage door has suffered serious damage over the years, you will need to turn to the expertise of a professional contractor, such as America's Garage Doors LLC, in order to have this damage repaired.
