Windows offer light, airflow, and visual appeal. However, they can also be entry points for unwelcome pests like termites. They commonly target window frames, especially where wood meets moisture.

Spotting termite damage early is crucial to keeping your windows functional and your home structurally sound. Learn the key signs of termite damage near windows that every homeowner should know.

1. Mud Tubes

Subterranean termites build mud tubes as passageways between their colonies and food sources. Homeowners commonly find these pencil-sized mud tubes near the base of windowsills or frames. They offer termites a moist environment, as they consist of:

• dirt,
• wood debris,
• and saliva.

Pro Tip

Breaking the tube and monitoring it for reconstruction can confirm the termites’ presence and activity.

2. Hollow-Sounding Wood

Knock gently on the window frame. Does it sound solid or hollow? Termites chew through wood from the inside out, resulting in a paper-thin outer layer.

If it sounds hollow or feels brittle when pressed, chances are that you have termites at work. Additionally, you may notice the wood crumbling in your hands as you inspect the wood.

3. Frass or Termite Droppings

Drywood termites, unlike their subterranean cousins, are notorious for leaving behind tiny, pellet-like droppings called frass. These tiny piles commonly accumulate along windowsills or beneath frames and are a clear indicator of drywood termite activity.

Pro Tip

It’s common for people to mistake frass for dirt or sawdust. Consider calling a professional if you’re unsure.

4. Visible Wood Damage

Take a close look at each window frame. Termite damage commonly manifests as grooves and tunnels in the wood, which can look like a maze-like pattern.

Advanced damage can result in thin, crisscrossing lines where termites have tunneled. Sometimes, the wood can also develop blistering or cracked surfaces resembling water damage.

How To Address Termite Damage

As much as compromised window frames can be unsightly, they can lead to further damage and loss. For instance, they can cause heat or air to escape the home, driving up energy costs. Avoid this by consulting a local professional contractor to assess whether you can salvage the frame or replace it entirely.
