How to Know If Your Window Seal is Broken: Causes and Solutions


Windows play a crucial role in maintaining the comfort, energy efficiency, and overall aesthetics of your home. At BT Window & Doors, we understand the importance of well-functioning windows and how a broken seal can impact your home. In this comprehensive guide, we will explain the signs of a broken window seal, why it happens, and what you can do about it.

What is a Window Seal?

A window seal is a crucial component designed to create a tight barrier between the panes of glass in double or triple-pane windows. Typically made from durable materials such as rubber gaskets or elastic sealants, window seals serve multiple important functions. They help keep out cold air, wind, rain, and pests, while also playing a key role in regulating indoor temperature. By maintaining an airtight seal, window seals enhance the comfort of your home, improve energy efficiency, and protect against the elements.

Signs of a Broken Window Seal

Identifying a broken window seal early can help prevent further damage and maintain your home's energy efficiency. Here are the primary indicators that your window seal may be compromised:

1. Foggy Windows: The most immediate and obvious sign of a broken window seal is fogging or condensation between the window panes. If you notice moisture that you cannot wipe away from either side of the glass, it's a clear indication that the seal is broken.

2. Distorted Views: A broken seal can cause the glass panes to slightly warp or bend, resulting in distorted views through your windows. If your view seems blurry or wavy, it could be due to a failed seal.

3. Increased Energy Bills: A broken window seal reduces the insulating properties of your windows, leading to increased energy usage. If you notice a sudden spike in your heating or cooling bills, it might be time to check your window seals.

4. Drafts and Temperature Fluctuations: Windows with broken seals often fail to maintain a consistent indoor temperature. You might feel drafts near the window or notice that certain areas of your home are cooler or warmer than others.

5. Visible Water or Ice: In extreme cases, a broken seal can lead to water or ice forming between the panes. This is a clear sign that moisture is entering through the compromised seal and can lead to further damage if not addressed promptly.

Causes of Broken Window Seals

Understanding what causes window seals to fail can help you take preventive measures. Here are some common reasons for broken seals:

1. Age and Wear: Over time, window seals naturally degrade due to exposure to the elements and the constant expansion and contraction caused by temperature changes. Older windows are more prone to seal failures.

2. Poor Installation: Improper installation can lead to premature seal failure. If the windows were not installed correctly, the seals might not have been adequately seated, leading to early wear and tear.

3. Thermal Pumping: Thermal pumping occurs when the air inside the window panes heats up and cools down, causing the panes to expand and contract. This constant movement can weaken the seals over time.

4. Manufacturing Defects: In some cases, manufacturing defects can cause window seals to fail. Poor-quality materials or assembly issues can lead to premature seal breakdown.

5. Environmental Factors: Extreme weather conditions, such as intense heat, cold, or humidity, can accelerate the degradation of window seals. Additionally, exposure to UV rays can break down the sealant materials.

What to Do If Your Window Seal is Broken

If you suspect that your window seal is broken, it's essential to take action to address the issue. Here are some steps you can take:

1. Confirm the Diagnosis: Before taking any action, ensure that the issue is indeed a broken seal. Check for the signs mentioned earlier, such as condensation between the panes and distorted views.

2. Consult a Professional: Contact a professional window service, like BT Window & Doors, to assess the situation. Our experts can provide an accurate diagnosis and recommend the best course of action to address the broken seal.

3. Consider Repair or Replacement: Depending on the severity of the seal failure and the condition of the window, you may need to choose between repair and replacement. Here are some options:

  • Repair: In some cases, professionals can repair the seal by removing moisture, cleaning the interior, and resealing the window. However, this is often a temporary fix and may not fully restore the window's insulating properties.

  • Replacement: For long-term solutions, replacing the affected window pane or the entire window unit is often the best choice. New windows will provide better energy efficiency, clarity, and overall performance.

  • 4. Upgrade to Energy-Efficient Windows: If you decide to replace your windows, consider upgrading to energy-efficient options. Windows with Low-E glass offer superior insulation and can significantly reduce your energy bills.

    5. Regular Maintenance: To prevent future seal failures, regular window maintenance is essential. Keep your windows clean, check for signs of wear and tear, and ensure proper installation. Periodic inspections by professionals can also help identify potential issues before they become major problems.
