A leaking window can quickly turn into a frustrating and expensive issue for homeowners. Not only are they annoying, but leaks can cause serious damage. This includes wood rot, mold growth, and higher energy bills if air escapes through gaps. The good news is that many leaks can be traced back to a handful of common causes. Knowing what to look for will help you catch problems early so you can protect your home.
1. Improper Installation
Sometimes, the problem actually originates from installation. If a window isn’t installed correctly—whether it’s not level, sealed incorrectly, or has gaps around the frame—water can sneak in, especially during heavy storms.
2. Aging or Damaged Seals
Over time, the seals around windows naturally wear down. Exposure to changing temperatures, sunlight, and moisture can cause seals to crack or become brittle, leaving openings where water can slip through.
3. Gutter or Drainage Issues
Your gutter system plays a big role in directing water away from your home. If gutters or downspouts are clogged or damaged, water can pool around windows, finding its way inside.
4. Cracks in Frames or Walls
Structural damage is another common reason for window leaks. Cracks in the window frame, siding, or surrounding walls can provide an easy pathway for water to enter your home.
