Our Skylight Leak Repair Solutions

We focus on finding the exact cause of leaks, fixing any damage to the skylight’s structure, and repairing key parts like window flashing and seals. Our process ensures that repairs are precise and long-lasting to prevent future problems.

Targeted Leak Source Identification

We begin by carefully inspecting the skylight to locate where the water is coming in. This often means checking the glass panels, frame joints, and roof areas around the skylight. We use moisture meters and visual checks to spot hidden leaks.


Once we find the leak source, we pinpoint whether it is caused by cracks, gaps, or damaged flashing. This step is crucial because fixing the wrong area wastes time and money. Our targeted approach allows us to address the real cause quickly and effectively.

Structural Damage Restoration

Leaks can weaken the skylight frame or the roof structure. We assess all surrounding damage to avoid hidden issues that might get worse later. This includes checking wood rot, mold, and warped materials caused by water exposure.


If damage is found, we replace or reinforce weakened parts using materials that blend with the existing structure. Repairing the structure restores the skylight’s strength and makes sure it functions properly for years.

Repair of Window Flashing & Seals

Flashing and seals protect the skylight from water entry. Over time, flashing can pull away or get damaged, while seals may dry out or crack. We examine all of these areas carefully.


Our team repairs or replaces flashing to create a tight waterproof barrier between the skylight and roof. Then we apply high-quality sealants on joints and edges. These repairs prevent water from entering and extend the life of the skylight system.

Our Resealing and Waterproofing Process

We focus on thorough cleaning, skilled sealant application, and measures that keep the skylight watertight for years. Each step targets durability and reliability to prevent future leaks.

Preparation and Cleaning

Before resealing, we remove old sealant and debris around the skylight frame. This ensures no dirt or residue blocks proper adhesion.


We carefully clean the surface using non-abrasive tools and a mild cleaning solution. This removes oils and dust that could weaken the seal.


Drying the area completely is essential. Moisture trapped under new sealant can cause it to fail quickly.


Our team inspects the frame and glass edges for cracks or damage during cleaning. Identifying issues early helps us fix them before sealing.

Sealant Application

After preparation, we apply high-quality silicone or polyurethane sealants. These materials create flexible, waterproof barriers.


We use precision tools to spread the sealant evenly along all seams, gaps, and corners. This prevents water from seeping through tiny openings.


Sealants are selected based on weather resistance and compatibility with skylight materials, ensuring strong bonds that last.


The sealant curing time is carefully observed. This allows the material to set fully, preventing premature failure or shrinkage.

Ensuring Long-Term Water Resistance

To protect the seal, we check for proper drainage around the skylight. Water paths are cleared to avoid pooling.


We inspect flashings and roof connections, tightening or replacing as needed to prevent leaks.


Periodic maintenance advice is shared with clients, such as cleaning debris and inspecting seals yearly.


Our goal is to extend the life of the resealing work, reducing chances of leaks from weather wear or building movement.

Types of Skylight Windows We Service

We work with a wide range of skylight windows to fix leaks and reseal properly. Our experience covers many styles and materials.


Some common types we service include:

  • Fixed skylights: These do not open and are often set in a frame.
  • Ventilated skylights: These open to allow air flow and need special care to seal.
  • Tubular skylights: These use a reflective tube to bring light inside and have unique sealing needs.


We also handle different frame materials like aluminum, wood, and vinyl. Each material requires a specific approach to prevent leaks.


Our team is ready to work with both flat and domed skylights. Flat skylights tend to collect water differently than domed ones, so we adjust our methods accordingly.


If you have custom or specialty skylights, we can inspect those too. Our goal is to find the best repair and sealing solution for every type you have.

Frequently Asked Questions About Skylight Window Leak Repair and Resealing

  • What is the typical process for repairing a leak in a skylight window?

    We start by checking the skylight for cracks, damaged seals, or debris. Next, we clean the area and remove old sealant. Then, we apply a new waterproof sealant and test for leaks to ensure the repair is effective.



  • How do you determine if a skylight window needs resealing or a full replacement?

    We assess the condition of the frame, glass, and seals. If the damage is limited to worn-out sealant or small gaps, resealing is enough. If the frame or glass is cracked or warped, a full replacement may be necessary.



  • Can any type of skylight window be resealed to fix leaks, or are there limitations?

    Most skylights can be resealed, but older or severely damaged models might not hold new sealant well. Certain materials like wood may need special treatment. We evaluate each skylight’s condition to decide the best fix.



  • What are the most common reasons for leaks in skylight windows?

    Leaks usually happen due to cracked glass, failed seals, poor installation, or buildup of debris blocking drainage. Weather damage and aging materials also contribute to leak problems.



  • How long does it usually take to repair and reseal a leaking skylight window?

    Repairs typically take between one to three hours. Larger or more complex leaks may need more time. We aim to complete work efficiently while ensuring a watertight seal.
