Skylights are a wonderful addition to any home, providing natural light and a unique aesthetic. However, to ensure they continue to enhance your living space, regular cleaning and maintenance are essential. In this article, we’ll guide you through the process of cleaning and maintaining skylights yourself.

Understanding Skylight Components:

Before diving into the cleaning process, it’s important to understand the components of your skylight. Most skylights consist of a frame, glazing, and seals. Familiarize yourself with these elements to ensure a thorough cleaning and maintenance routine.

Gathering Necessary Tools:

Cleaning and maintaining skylights doesn’t require specialized equipment. You’ll need a soft brush, mild detergent, a squeegee, and a ladder if your skylights are out of reach. Avoid harsh chemicals that can damage the frame or glazing.

Exterior Cleaning:

Start by addressing the exterior of your skylights. Remove any debris, leaves, or twigs that may have accumulated on the frame. Gently brush away dirt and grime using a soft brush. For stubborn stains, create a solution of mild detergent and water, and carefully scrub the affected areas.

Cleaning the Glazing:

The glazing, usually made of glass or plastic, requires special attention. Mix a mild detergent with water and use a soft cloth or sponge to clean the glazing. If your skylights have multiple panes, be thorough in cleaning each one. Avoid abrasive materials that could scratch the surface.

Inspecting Seals for Wear:

Skylight seals are crucial for preventing leaks and maintaining energy efficiency. Inspect the seals for signs of wear, cracks, or damage. If you notice any issues, consider replacing the seals to ensure your skylights remain watertight and well-insulated.

Interior Cleaning:

Move inside to clean the interior part of your skylights. Dust and wipe down the frame with a soft cloth. If your skylights open, check the tracks and hinges for any debris that may hinder their functionality. Wipe down the interior glazing with the same mild detergent solution used for the exterior.

Ensuring Proper Ventilation:

If your skylights are designed to open, check the ventilation mechanism. Lubricate hinges and tracks with a silicone-based lubricant to ensure smooth operation. Properly functioning ventilation is essential for maintaining a comfortable indoor environment.

Checking for Condensation:

Condensation on skylights can be indicative of a ventilation issue or high humidity levels. Address any condensation promptly to prevent mold growth and water damage. Ensure that your home is adequately ventilated, especially in areas with high moisture levels.

Inspecting for Leaks:

Regularly inspect your skylights for any signs of leaks. During heavy rain, check for water intrusion around the frame and seals. If you notice leaks, address them promptly to prevent water damage to your home’s interior.

Establishing a Cleaning Schedule:

To maintain the longevity and appearance of your skylights, establish a regular cleaning schedule. Consider cleaning them at least twice a year, more frequently if you live in an area with heavy precipitation or surrounded by trees.


Clean and well-maintained skylights not only enhance the aesthetic appeal of your home but also contribute to a healthier living space. By understanding the components of your skylights and following a simple cleaning and maintenance routine, you can enjoy the benefits of natural light without compromising on efficiency.
