How to Repair a Garage Door

As a result of fluctuating outdoor temperatures and high humidity levels, wood garage doors will often crack and develop small holes over the years. While this damage does not typically interfere with the operation of the door, it can have a rather significant impact on the way the door looks. Thankfully, repairing this type of cosmetic damage can be much easier than many people realize.

What You Will Need

In order to complete this repair, you will need the following supplies. All of these supplies can be purchased at a local hardware or home improvement store for a relatively low cost.

– sandpaper (varying grits)
– sanding block
– wood putty
– putty knife
– rotary tool
– wood stain or paint
– 2 paintbrushes

Step 1: Clean Away Debris

The most important part of ensuring a successful repair is to make sure you are working with a clean surface. This means cleaning away any dirt, damaged wood, existing paint, and other debris.

Start by using your sanding block and a heavy grit sandpaper to take off any existing paint and other debris from the surface of the door. Be sure to always go with the grain and apply a minimal amount of pressure so that you only take off the top layer of finish and do not further damage the door’s surface.

Next, use a rotary tool to reach into the damaged areas of your door and gently sand away wood splinter, as well as any other debris that may be present.

Finally, use one of clean paintbrushes to brush away any loose dirt or sawdust that is left on the door.

Step 2: Repair The Damaged Areas Of Your Door

Now that your garage door is ready to be repaired, start by using your putty knife to apply wood putty to each of the damaged areas. Be sure to push the putty as deep into the damaged area as possible in order to ensure a long lasting repair.

After the area is filled in, use the flat side of your knife to remove any excess putty from the door and smooth out the surface of the repair patch.

Allow the wood putty to dry overnight to ensure it is fully cured before moving on with the repair process. When returning to the job the next day, use a fine grit sandpaper to gently go over the repaired areas until they are flush with the rest of the door and completely smooth to the touch.

Step 3: Apply A Finishing Touch

Wood stain or paint will not only give your door a more finished appearance, but it will also help to protect your door from future damage by sealing out moisture. This is why it is so important to apply a fresh coat of stain or paint after completing any repairs to your wood garage door.

A Final Thought

While most garage door damage can be repaired quite easily on a do-it-yourself basis, some repairs will require the attention of a professional contractor. If you find that the damage to your door is interfering with the door’s operation or if you are struggling to complete the repairs on your own, do not be afraid to reach out to a qualified contractor in your local area to ensure the job is done right.
