A cornice is an architectural element that provides decorative or protective finishes to the eaves and/or edges of a building. They are often used on the exterior of a building but can also be used on the interior to create a decorative finish. Cornices can be made from various materials, including wood, stone, plaster, metal and even plastic.

How to Take Care of Your Cornice

If you have a cornice in your home, it is important to take care of it to keep it looking its best and to prevent it from becoming damaged. Here are a few tips for taking care of your cornice:

1. Dust Regularly

Cornices are a beautiful and elegant addition to any room, but they can also be a bit of a dust magnet. To keep your cornices looking their best, it’s important to dust them regularly with a soft, dry cloth. Avoid using abrasive cleaners or brushes, as these can damage the cornice.

2. Protect from Sunlight

Unfortunately, cornices can be susceptible to damage from the sun. Sunlight can fade or damage cornices, so it’s important to protect them from direct sunlight whenever possible. Use curtains or blinds to shield your cornices from the sun’s rays.

If you need to expose your cornices to sunlight, be sure to do so gradually. Sudden exposure to sunlight can cause cornices to warp or crack. And be sure to inspect your cornices regularly for any signs of damage.

3. Avoid Moisture

A cornice is a decorative element often used to add architectural interest to a room. They are typically made of wood or plaster and can be either simple or ornate in design. Cornices can be damaged by moisture, so it’s important to avoid hanging wet laundry on them and to wipe up any spills quickly. When choosing a cornice for your home, it’s important to consider the overall style of the room and the materials that will best complement it.

4. Repair Cracks Promptly

Cracks in cornices can worsen over time, so it’s important to repair them as soon as possible. There are a few different ways to repair cracks in cornices, depending on the severity of the damage. For small cracks, you can use a plaster or wood filler to fill in the crack and then paint or varnish over the repair. For more serious damage, you may need to replace the entire cornice.

5. Add Support If Needed

If your cornice starts to sag or crack, it may need additional support. You can add support by screwing brackets into the wall or by installing a cornice box.

When installing a cornice box, it is important to ensure that the box is the correct size for your window or door. The box should be slightly larger than the opening so it can be properly secured. You will also need to choose a cornice box that is compatible with the material of your cornice. For example, you must choose a wood cornice box if your cornice is made from wood.


It is important to take care of your cornice to maintain the integrity of your home’s exterior. Cornices are susceptible to weather damage, so it is important to inspect them regularly and make repairs as needed. You can avoid costly repairs by regularly cleaning your cornice and keeping it in good repair.
