Rot often appears as soft, spongy wood that crumbles easily. It may be darkened or discolored compared to unaffected areas.

Small holes, frass (wood dust), or tunnels in the wood indicate an insect infestation, such as termites or carpenter ants.

Rot-damaged wood may swell, warp, or crack due to moisture intrusion, while insect activity can leave cracks in the frame.

Paint that blisters, peels, or flakes is a warning sign of moisture retention and potential rot beneath the surface.

Frames affected by rot or insect damage may swell, making windows hard to open or close properly.

Seeing live insects near or inside the window frame can indicate an active infestation.

Poor drainage, leaky gutters, or damaged caulking can allow water to accumulate around window frames, leading to wood rot.

Windows without protective paint or stain are more vulnerable to weather damage and insect infestations.

Small openings in window frames or seals provide entry points for insects seeking shelter or food.

Excessive indoor humidity or poor airflow can create damp conditions that encourage rot and attract moisture-loving insects.

Compromised frames lose their ability to support the window, potentially leading to more extensive repairs or replacements.

Damaged windows can create gaps that allow drafts, reducing energy efficiency and increasing heating and cooling costs.

Rot and insect damage often create pathways for water to enter the home, leading to mold, mildew, and further structural issues.

Untreated insect damage can spread to other parts of the home, causing widespread problems beyond the windows.

Decayed or insect-ridden windows detract from the property’s curb appeal and value.

Assess the extent of the rot or infestation. Check for signs of structural compromise, such as soft wood or loose frames.

Cut out and remove all affected wood, ensuring no traces of rot or insects remain.

Apply wood preservative to prevent further rot and use insecticide to eliminate pests.

Replace the damaged sections of the window frame with treated or composite materials. For extensive damage, consider replacing the entire window.

Apply caulk, paint, or stain to protect the repaired or replaced window from future moisture and pest damage.

Keep gutters and downspouts clear and direct water away from windows to prevent pooling.

Regularly inspect and repair caulking or weatherstripping around windows to prevent water infiltration.

Use weather-resistant paint or stain on wooden window frames to shield them from moisture and pests.

Conduct seasonal inspections of your windows to catch early signs of damage or infestation.

Use dehumidifiers and ensure proper ventilation to minimize indoor humidity, reducing conditions that encourage rot.

Use insect screens and close structural gaps to prevent pests from accessing window frames.
