Bulging Window Seals: What You Need to Know

Bulging Window Seals: What You Need to Know

At EGA Home Inspection, we often encounter various issues during our inspections—one of which is bulging window seals. This seemingly small issue can indicate larger problems with your windows and home efficiency.

In this blog, we’ll explore:

  • What causes bulging window seals
  • Why they matter
  • Steps you can take to address the issue

What Are Bulging Window Seals?

Window seals are designed to keep your windows airtight and energy-efficient by preventing drafts, moisture, and debris from entering.

When seals become deformed or begin to bulge, it’s a sign that they are failing. This failure not only compromises the seal’s effectiveness but can also lead to additional issues, such as:

  • Water intrusion
  • Energy loss
  • Damage to the window itself

What Causes Bulging Window Seals?

Bulging window seals can result from several factors, including:

  • Thermal Expansion and Contraction: Repeated exposure to extreme temperature changes can cause the seal material to expand and contract, leading to deformation over time.
  • Material Aging: Like all materials, seals deteriorate with age, especially when exposed to UV rays, moisture, and fluctuating weather conditions.
  • Improper Installation: If the seals were not installed correctly, uneven pressure or gaps may cause them to deform prematurely.
  • Moisture and Condensation: Excessive moisture buildup around windows can weaken the seal’s adhesion and structure, resulting in bulging or detachment.

Why Is This a Concern?

While bulging seals may seem like a minor aesthetic issue, they can have significant consequences for your home:

  • Reduced Energy Efficiency: Compromised seals can allow air to escape, making it harder to maintain a consistent indoor temperature and increasing energy bills.
  • Potential Water Intrusion: Damaged seals are less effective at keeping out moisture, which can lead to water damage, mold, and rot over time.
  • Window Integrity: In severe cases, a failing seal can affect the overall performance of the window, necessitating costly repairs or replacements.

What Should You Do?

If you notice bulging window seals in your home, it’s essential to act promptly. At EGA Home Inspection, we recommend the following steps:

  1. Inspect All Windows: Check for similar issues on other windows to understand the extent of the problem.
  2. Consult a Professional: A qualified window contractor can evaluate the severity of the issue and recommend appropriate solutions, such as resealing, replacing the gasket, or, in some cases, replacing the window entirely.
  3. Preventative Maintenance: Regularly inspect and maintain your windows to prevent issues like seal failure. Ensure proper cleaning, and address any signs of moisture or drafts early.
