A window drip cap is designed to help direct rainwater away from the top of your window or door, reducing the chance of leaks and water damage. By creating a small overhang, the drip cap helps prevent water from seeping into the frame or wall. This can be especially useful in areas with heavy rainfall or for exterior windows and doors. Installing a drip cap can help extend the life of your window frames and improve overall weather resistance.

Choosing the right size drip cap depends on the width of your window or door and the area you want to cover.

• Measure the length of the window or door top where the drip cap will be installed.
• Look for a drip cap that matches or slightly exceeds this measurement for full coverage.
• Consider the depth of the cap to ensure it extends far enough to divert water away from the frame.

Many drip caps are designed for easy DIY installation, especially self-adhesive or screw-on models.

• Start by cleaning and drying the area above your window or door.
• Follow the manufacturer's instructions, which may involve peeling off a backing for adhesive caps or using screws for metal ones.
• Make sure the cap is level and securely attached to prevent water from getting behind it.

While drip caps are most commonly used on exterior windows and doors to prevent rainwater intrusion, some models can also be used indoors.

• Indoor applications may include areas prone to moisture, like shower doors or balcony entrances.
• Flexible silicone or TPE drip caps can help manage water in bathrooms or kitchens.

Keeping your window drip cap clean helps it work effectively.

• Wipe down the cap with a damp cloth to remove dirt and debris.
• For stubborn buildup, use mild soap and water, avoiding harsh chemicals that could damage the material.
• Inspect regularly for cracks or signs of wear, especially after storms.
