VELUX Windows Leaking: Solutions and Fixes
Posted by Lawrie Fraser on 23rd November 2023
VELUX windows are a popular choice for homeowners looking to add natural light and ventilation to their homes. However, over time, these windows may begin to leak, causing damage to the interior of the house. Understanding the causes of VELUX window leaks and how to fix them is essential for maintaining the integrity of your home.
One common cause of VELUX window leaks is incorrect installation. Poor installation practices, such as using old tools and sealing techniques or inexperienced roofers fitting window frames at pitched angles, can cause leaks. In such cases, resealing the window can help stop the leaks. Another common cause of VELUX window leaks is flashing installed incorrectly, which can develop wear and tear over the years. Debris, leaves, and moss often accumulate over the flashing, which also causes window leaks.
Identifying a Leaking VELUX Window
VELUX windows are known for their quality and durability. However, they can still develop leaks over time. It's essential to identify the cause of the leak before attempting any repairs. Here are some signs that your VELUX window is leaking:
- Water stains on the ceiling or walls around the window
- Damp or wet patches on the window frame or sill
- Condensation on the inside of the window
- A musty smell in the room
If you notice any of these signs, it's crucial to act quickly to prevent further damage to your home. Start by inspecting the window for any visible damage or wear and tear. Check the frame, the glass, and the seals for any cracks, gaps, or missing parts.
Another common cause of VELUX window leaks is faulty flashing. Flashing is a thin metal or plastic strip that covers the gap between the window frame and the roof. It helps to direct water away from the window and prevent leaks. If the flashing is damaged or installed incorrectly, water can seep through and cause leaks.
It's also essential to check the roof for any damage or missing tiles. If the roof is damaged, water can seep through and cause leaks around the window. In some cases, the leak may not be coming from the window at all, but from the roof.
In conclusion, identifying a leaking VELUX window is the first step in fixing the problem. Look for signs of water damage, inspect the window for visible damage, and check the flashing and roof for any issues. By identifying the cause of the leak, you can take the necessary steps to fix it and prevent further damage to your home.
Common Causes of Leaks
VELUX windows are designed to be durable and long-lasting, but they are not immune to leaks. There are several reasons why VELUX windows may leak, including:
- Flashing issues: Flashing is the material that seals the gap between the window and the roof. If the flashing is damaged, installed incorrectly, or missing altogether, water can seep through and cause leaks.
- Condensation buildup: Condensation buildup in VELUX windows is a common problem that can be caused by a lack of ventilation and/or improper insulation. When humidity levels become too high inside your home, condensation droplets will form on the glass panes of the VELUX window.
- Roofing problems: Leaks can also occur when there are problems with the roof. For example, if the roof tiles are damaged or missing, water can seep through and cause leaks around the VELUX window.
- Installation issues: If the VELUX window was not installed correctly, it can cause leaks. For example, if the window is not level or if there are gaps between the window and the roof, water can seep through and cause leaks.
- Debris accumulation: Debris, such as leaves and moss, can accumulate over the flashing and cause leaks. It is important to regularly clean the area around the VELUX window to prevent debris buildup.
It is important to identify the cause of the leak before attempting to fix it. If you are unsure of the cause of the leak or how to fix it, it is recommended to seek professional help.
Preventive Measures Against Leaks
VELUX windows are generally reliable and long-lasting, but they can still develop leaks over time. Fortunately, there are several preventive measures you can take to minimize the risk of leaks.
Regular Maintenance
Regular maintenance is essential for preventing leaks in VELUX windows. Homeowners should clean the windows and frames at least twice a year to remove any dirt, debris, or mould that may have accumulated. This will help to prevent water from seeping through gaps and cracks in the window frame.
Additionally, homeowners should inspect the windows regularly for signs of wear and tear. This includes checking the flashing, seals, and gaskets for any cracks or damage. If any problems are detected, they should be addressed immediately to prevent water from entering the home.
Proper Installation
Proper installation is another key factor in preventing leaks in VELUX windows. When installing a VELUX window, it is important to follow the manufacturer's instructions carefully. This includes ensuring that the flashing is installed correctly and that there are no gaps or spaces around the window frame.
Homeowners should also ensure that the window is installed at the correct angle to prevent water from pooling on the surface. If the window is installed at an angle that is too low, water may collect on the surface and seep through gaps in the frame.
In summary, regular maintenance and proper installation are the two most important preventive measures against leaks in VELUX windows. By following these guidelines, homeowners can minimize the risk of water damage and ensure that their windows remain in good condition for years to come.
Steps to Fix a Leaking VELUX Window
VELUX windows are known for their durability and quality, but like any other window, they may develop leaks over time. If you notice water stains or drips around your VELUX window, it's essential to fix the issue as soon as possible to prevent further damage to your roof and home. Here are some steps to fix a leaking VELUX window:
Reapplying Sealant
One of the most common causes of VELUX window leaks is damaged or worn-out sealant. If you notice cracks or gaps in the sealant around your window frame, it's time to reapply it. First, remove the old sealant using a scraper or a putty knife. Then, clean the area with a damp cloth and let it dry completely. Apply a new layer of sealant around the window frame, making sure to fill in any gaps or cracks. Finally, smooth out the sealant using a caulking gun or your finger.
Replacing Damaged Parts
If reapplying sealant doesn't fix the issue, it's possible that some parts of your VELUX window are damaged or worn out. Check the window gasket, flashing, and weatherstripping for any signs of damage. If you notice any cracks, holes, or tears, it's time to replace the damaged parts. You can purchase replacement parts from VELUX or a certified dealer. Follow the manufacturer's instructions to replace the damaged parts.
Professional Repair Services
If you're not comfortable fixing the issue yourself, or if the leak is severe, it's best to call a professional repair service. A certified VELUX installer or a roofing contractor can diagnose the issue and fix it quickly and efficiently. They have the necessary tools and expertise to repair any VELUX window leaks. Moreover, if your VELUX window is still under warranty, it's best to call a professional repair service to avoid voiding the warranty.
In conclusion, fixing a leaking VELUX window is crucial to prevent further damage to your roof and home. Reapplying sealant, replacing damaged parts, or calling a professional repair service are some steps you can take to fix the issue. Make sure to follow the manufacturer's instructions and take safety precautions when fixing the issue yourself.
