Skylights are a fantastic addition to any home, providing natural light and a unique aesthetic touch. However, like any other part of your home, skylights can suffer from wear and tear over time, leading to leaks, drafts, and other problems.

But what should you do when dealing with skylight damage? In this comprehensive guide, we will explore:

  • Common sources of skylight damage
  • How to repair a skylight
  • The costs involved
  • Tips for finding a reputable contractor to help you with the process

Common Reasons for Skylight Damage

Whether you are dealing with a skylight leak or cracks in the glass, skylight damage can be frustrating. The first step in dealing with a leaking skylight or any other damage is to find out what caused the damage in the first place. Here are a few of the common culprits:

  • Weather and Age: Skylights are exposed to the elements year-round, which can lead to wear and tear. Over time, weather conditions such as rain, hail, and strong winds can damage the skylight’s frame, sealant, and glazing. Aging skylights may also experience deterioration in their materials, making them more susceptible to damage.
  • Poor Installation: Improper installation is a frequent cause of skylight problems. If the flashing, sealant, or frame is not installed correctly, it can lead to leaks and drafts. This is why it’s crucial to hire a professional for skylight installation to ensure it is done correctly from the start.
  • Condensation: Skylights can develop condensation on their interior surface, especially during temperature fluctuations. If not properly managed, this moisture can damage the frame and surrounding materials over time.
  • Debris Buildup: Debris like leaves, twigs, and dirt can accumulate around and on top of skylights, leading to clogs and water pooling. This can compromise the integrity of the skylight’s structure and lead to leaks.

How to Repair a Skylight in 7 Steps

Repairing a skylight may seem like a daunting task, but with the right tools and knowledge, you can tackle many common issues. Here’s a step-by-step guide to repairing your skylight:

1) Safety First

Before starting any repair work, ensure your safety by wearing appropriate protective gear and using a sturdy ladder if necessary. Exercise caution when working at heights.

2) Identify the Problem

Begin by inspecting the skylight to identify the source of the damage. Look for cracks in the glazing, damaged seals, or visible leaks during rainy weather.

3) Replace Damaged Seals

If you notice that the seals around the skylight have deteriorated or are damaged, you can replace them. Remove the old sealant carefully and apply a new, high-quality sealant compatible with your skylight’s material.

4) Fix Glazing Issues

Cracked or damaged glazing can be a common problem. Depending on the severity of the damage, you may need to replace the entire glazing or use a sealant to fill in minor cracks.

5) Clear Debris

Remove any debris or clogs around the skylight to prevent future damage. Regularly clean the area to avoid buildup and maintain the skylight’s functionality.

6) Address Condensation

If condensation is a recurring issue, consider installing ventilation to regulate the humidity around the skylight. Proper ventilation can help prevent moisture-related damage.

7) Seek Professional Help

Some skylight repairs may require specialized knowledge and equipment. If you’re unsure or uncomfortable with any aspect of the repair, it’s best to hire a professional skylight contractor.

How Much Does Skylight Repair Cost?

The cost of repairing a skylight can vary widely depending on the extent of the damage and the type of skylight you have. Here’s a breakdown of potential costs:

  • DIY Repairs: If you can address the issue yourself, the cost may be limited to the price of sealant or replacement glazing, which can range from $20 to $100 or more, depending on the product’s quality and size.
  • Professional Repairs: Hiring a professional skylight contractor is recommended for complex or extensive repairs. The cost of professional repair services can range from $200 to $1,500 or more, depending on the nature of the repair and labor costs in your area.
  • Skylight Replacement: In some cases, the damage to your skylight may be severe enough to warrant a complete replacement. Skylight replacement costs can vary significantly, ranging from $500 to $5,000 or more, depending on the size, type, and features of the new skylight.
  • Additional Costs: Keep in mind that additional costs may arise if the skylight damage has led to interior water damage or structural issues in your home. Repairing these secondary damages can add to the overall cost of skylight repair.

How to Find a Reputable Contractor for Skylight Repair

When it comes to repairing or replacing your skylight, hiring a reputable contractor is crucial to ensure the work is done correctly and to avoid potential issues down the road. Here are some tips for finding the right professional for the job:


Start by conducting online research to identify local skylight contractors with positive reviews and a strong reputation. Check websites, online directories, and customer feedback to gather information about potential contractors.

Ask for Recommendations:

Seek recommendations from friends, family, or neighbors who have recently had skylight repairs or installations. Personal referrals can provide valuable insights into a contractor’s reliability and workmanship.

Verify Licensing and Insurance:

Ensure that any contractor you consider is properly licensed and insured. This protects you in case of accidents or issues during the repair process.

Request Quotes:

Contact multiple contractors to request quotes for your skylight repair or replacement project. Compare the quotes, taking into account the scope of work, materials used, and estimated completion time.

Check References:

Ask potential contractors for references from previous clients. Contact these references to inquire about their experiences with the contractor, including the quality of work, professionalism, and timeliness.

Review Contracts:

Before hiring a contractor, carefully review the contract, including payment terms, warranties, and a detailed description of the work to be performed. Make sure you understand and agree to all terms before signing.


Effective communication is essential throughout the project. Choose a contractor who is responsive to your questions and concerns and keeps you updated on the progress of the repair.
