Skylight Cleaning: Bringing Natural Light Back into Your Building

by | Feb 18, 2024 | Window Cleaning | 0 comments


Natural light is a precious commodity, not just for its aesthetic appeal but also for its positive impact on our well-being. Skylights, designed to allow sunlight into a building, play a pivotal role in maximizing the benefits of natural light. In this article, we’ll delve into the importance of skylight cleaning, the benefits it offers, and how to maintain these architectural features effectively.

Benefits of Skylights

Improved Mood and Productivity

Skylights have been proven to enhance mood and increase productivity among building occupants. Exposure to natural light boosts serotonin levels, promoting a sense of well-being and focus. Clean skylights ensure the unhindered flow of sunlight, maximizing these benefits.

Energy Efficiency

Skylights contribute to energy efficiency by reducing the need for artificial lighting during the day. Regular cleaning ensures that the skylights remain clear, allowing optimal light penetration and minimizing reliance on electric lighting.

Cost Savings

In addition to energy savings, well-maintained skylights contribute to cost savings by extending the lifespan of the windows. Preventing dirt buildup and potential damage through cleaning can save significant repair or replacement expenses.

Challenges in Skylight Cleaning

Maintaining skylights involves addressing various challenges, including the accumulation of dirt, water stains, and the growth of mold and mildew. Over time, these issues can hinder the effectiveness of skylights and compromise their aesthetic appeal.

Importance of Regular Cleaning

Regular skylight cleaning is essential to enhance natural light penetration, prevent damage, and maintain a clean and appealing appearance. Let’s explore some effective tips for both do-it-yourself (DIY) cleaning and hiring professional services.

DIY Skylight Cleaning Tips

Gather Necessary Supplies

Before starting the cleaning process, gather supplies such as a soft brush, mild detergent, squeegee, and a non-abrasive cloth. Ensure you have a sturdy ladder and take necessary safety precautions.

Safety Precautions

Safety should be a top priority during DIY cleaning. Use a stable ladder, wear appropriate safety gear, and have someone nearby for assistance. Avoid overreaching and be mindful of the skylight’s fragility.

Step-by-Step Cleaning Process

  1. Remove loose debris: Begin by gently removing any leaves, twigs, or other debris from the skylight.
  2. Mix a mild detergent solution: Create a solution using a mild detergent and water.
  3. Apply the solution: Use a soft brush or sponge to apply the detergent solution to the skylight surface.
  4. Scrub gently: Work in circular motions, paying attention to any stained or soiled areas.
  5. Rinse with clean water: Use a hose or a bucket of clean water to rinse away the detergent.
  6. Dry with a squeegee: Finish by using a squeegee to remove excess water and prevent streaks.

Hiring Professional Skylight Cleaning Services

While DIY cleaning is an option, there are distinct advantages to hiring professional skylight cleaning services. Professionals have the experience, equipment, and expertise to ensure thorough cleaning without risking damage to the skylight.

Advantages of Professional Cleaning

  • Expertise in handling different types of skylights and materials.
  • Use of specialized cleaning solutions for optimal results.
  • Thorough inspection for any potential issues.

Choosing the Right Cleaning Service

When selecting a professional cleaning service, consider their reputation, experience, and customer reviews. Ensure they are licensed and insured to guarantee quality service and protection against potential accidents.

Frequency of Professional Cleaning

The frequency of professional cleaning depends on various factors, including the location of the building, surrounding environmental conditions, and the type of skylights. Consulting with a professional can help determine the most suitable cleaning schedule.

Common Mistakes to Avoid

In the pursuit of a clean skylight, some common mistakes should be avoided to prevent damage and ensure effective cleaning.

Using Abrasive Materials

Avoid using abrasive materials or harsh chemicals that can scratch or damage the skylight surface. Stick to gentle cleaning solutions and soft tools.

Neglecting Proper Safety Measures

Whether cleaning DIY or hiring professionals, neglecting safety measures can lead to accidents. Always prioritize safety by using secure ladders, wearing appropriate gear, and working in pairs when possible.

Ignoring Early Signs of Damage

Be vigilant for early signs of damage, such as leaks or cracks. Ignoring these issues can lead to more extensive and costly repairs in the future.

Skylight Maintenance Tips

In addition to regular cleaning, ongoing skylight maintenance is crucial for preserving their functionality and appearance.

Regular Inspections

Periodically inspect skylights for any signs of damage, such as cracks, leaks, or discoloration. Early detection allows for timely repairs.

Clearing Surrounding Debris

Trim overhanging branches and remove any debris on the roof to prevent it from accumulating on the skylight. This helps maintain optimal light transmission.

Checking for Leaks

Regularly check for leaks, especially after heavy rainfall. Leaks can lead to water stains and mold growth if left unaddressed. Promptly fix any identified issues to prevent further damage.

Choosing the Right Cleaning Products

Selecting the appropriate cleaning products is vital to ensure effective cleaning without harming the skylight materials.

Non-Abrasive Cleaners

Opt for non-abrasive cleaners that are specifically designed for use on glass or other skylight materials. These cleaners effectively remove dirt and stains without causing damage.

Environmentally Friendly Options

Consider using environmentally friendly cleaning options to minimize the impact on the surrounding ecosystem. There are eco-friendly cleaning solutions available that are effective and safe for both your skylights and the environment.

Products Suitable for Different Skylight Materials

Different skylights are made from various materials such as glass, acrylic, or polycarbonate. Ensure that the cleaning products you choose are suitable for the specific material of your skylights to avoid any adverse reactions.

Addressing Specific Skylight Issues

Sometimes, skylights may present specific issues that require targeted solutions.

Removing Stubborn Stains

For stubborn stains, a mixture of vinegar and water or a baking soda paste can be effective. Apply the solution, let it sit for a few minutes, and then gently scrub the stained area.

Dealing with Mold and Mildew

A solution of hydrogen peroxide and water can be effective in tackling mold and mildew. Ensure proper ventilation during cleaning, and use protective gear such as a mask and gloves.

Polishing and Preventing Scratches

To polish and prevent scratches, use a specialized plastic or glass polish. Apply the polish according to the manufacturer’s instructions to maintain the clarity and appearance of your skylights.

DIY vs. Professional Cleaning Cost Comparison

When deciding between DIY cleaning and hiring professionals, it’s essential to consider the cost implications.

Calculating the Cost of DIY Cleaning

Factor in the cost of cleaning supplies, your time, and any potential risks or damages that may occur during the DIY cleaning process. While DIY may seem cost-effective, it’s crucial to weigh the benefits against the potential drawbacks.

Evaluating the Value of Professional Services

Professional cleaning services come with a cost, but they offer expertise, efficiency, and the assurance of a thorough cleaning job. Consider the long-term savings in terms of skylight longevity and energy efficiency when evaluating the value of professional services.

Long-Term Savings through Professional Cleaning

Regular professional cleaning not only extends the lifespan of your skylights but also contributes to long-term savings by minimizing the need for repairs or replacements. The investment in professional services pays off in terms of aesthetics, functionality, and cost efficiency.

Customer Testimonials

Positive Experiences with DIY Cleaning

Many individuals have successfully cleaned their skylights using DIY methods. They praise the simplicity of the process and the satisfaction of maintaining their skylights on their own.

Success Stories with Professional Cleaning Services

Customers who have opted for professional cleaning services highlight the convenience, thoroughness, and lasting results provided by trained professionals. Positive testimonials emphasize the value of investing in expertise for skylight maintenance.


In conclusion, skylights play a crucial role in bringing natural light into your building, contributing to a positive and energy-efficient environment.
