Insects like termites or carpenter ants create small holes or channels as they burrow into the door, particularly wooden doors.

Wooden doors may develop soft, spongy spots that feel weak or mushy when touched. This is usually a sign of rot caused by moisture or insect infestation.

When tapping on the door, you may hear a hollow or dull sound in areas affected by rot or insects, indicating internal damage.

Rot often causes wood to change color, becoming darker or more yellow. Moisture or insect activity can also lead to water stains or mildew growth.

If you notice piles of sawdust or frass (the debris left behind by insects like termites or wood-boring beetles), it's an indicator of active infestation.

In some cases, you may see insects such as termites, carpenter ants, or beetles around the door, indicating they are actively infesting the area.

Termites are the most common culprits of insect damage to wooden garage doors. They feed on cellulose in wood, causing structural damage that weakens the door.

Carpenter ants don't eat wood but carve out galleries in wooden surfaces to create nests, leading to weakening and potential structural failure.

Wooden garage doors are particularly susceptible to rot when exposed to excessive moisture, whether from rain, humidity, or poor drainage.

A lack of protective paint, sealant, or regular maintenance allows insects to infiltrate the wood and moisture to penetrate, leading to rot.

Poor ventilation in the garage can increase moisture levels and promote the growth of mold, mildew, and rot, providing an ideal environment for insect infestations.

Thoroughly inspect the garage door for signs of insect damage or rot. Pay attention to any areas that feel soft or spongy, and look for visible signs of insects or holes.

If you suspect a termite or carpenter ant infestation, it may be necessary to consult a pest control professional to identify the insects and treat the problem.

If termites or ants are present, treat the affected area with an appropriate insecticide or hire a professional pest control service. Be sure to eliminate the source of the infestation to prevent recurrence.

For minor rot or insect damage, use wood filler or epoxy to fill small holes and cracks. Sand the surface smooth and repaint the door to restore its appearance.

For extensive damage, you may need to replace the affected panels or sections of the door. If the damage is significant, replacing the entire door may be the most cost-effective solution.

After repairs, apply a high-quality wood sealant or paint to protect the door from moisture and further insect damage. This creates a barrier that helps prevent both rot and insect infestation.

Make sure there’s adequate drainage around the garage door and proper ventilation in the garage. Use weatherstripping to seal gaps and prevent moisture from entering the door.

Address any moisture problems by repairing leaks or improving the garage’s ventilation. Installing a dehumidifier or ensuring proper airflow can help keep the door dry and prevent rot.

Periodically inspect your garage door for signs of damage, insect activity, or rot. Early detection can prevent costly repairs and extend the life of the door.

Keep the door sealed and painted to protect it from moisture and insects. Repaint or reseal the door every few years to ensure its durability.

Install proper drainage around the garage to prevent water from pooling near the door. Ensure gutters are clear and downspouts direct water away from the structure.

Consider using pest deterrents, such as termite repellents, around the garage door. If you suspect a serious infestation, call a pest control professional for an inspection and treatment.

Install barriers or shields around the door’s base or edges to prevent insects from entering. This can be especially helpful in high-risk areas.

If left untreated, insect damage and rot can spread, compromising the structural integrity of the garage door and requiring more costly repairs or replacement.

A damaged or weakened garage door may fail to operate properly, leaving your garage vulnerable to break-ins or damage.

Repairing insect damage and rot ensures that your garage door continues to protect your vehicle, belongings, and the interior of your garage from the elements.
