How to Fix a Leaking Window This Fall - Kansas City Leak Repair Tip
As Kansas City heads into colder months, now is the time to protect your home or business from costly window leaks.
Leaky windows may seem like a minor nuisance, but they can lead to significant problems, especially in the fall, when rain, humidity, and cooler temperatures collide. Left unchecked, leaks can cause structural damage, mold, and heat loss that drives up your utility bills. Let’s take a look at why window leaks happen, how to spot them, and what you can do before fall to seal and protect your space before the cold, damp weather of fall and winter settles in.
Why Window Leaks Are a Serious Problem in the Fall?
Temperature swings, moisture buildup, and aging window materials all contribute to leaks, especially in autumn. As the weather cools, window seals contract and fail, and water finds its way in during fall rains. Adding to the problem are drafty windows, reducing your home’s energy efficiency just as heating costs start to rise.
In Kansas City, where fall can bring cold snaps and moisture-heavy days, failing to address leaks now can result in:
- Water damage to frames, sills, and drywall
- Mold and mildew growth
- Increased energy bills due to heat loss
- Air drafts that make living areas uncomfortable
Common Signs of Leaking Windows to Watch For
If you’re unsure whether your windows are leaking, look for these telltale signs:
- Condensation between window panes
- Peeling paint or bubbling walls near windows
- Musty smells or mold growth
- Water pooling on the sill after storms
- Drafty, cold air is entering the room even when the windows are shut
- Warped or soft wood on the frame or sash
What Causes Window Leaks in Homes and Commercial Buildings
Leaks can affect all
types of windows, from residential bay windows to storefront commercial units. Common causes include:
- Cracked or shrinking caulk that no longer seals properly
- Broken or failed window seals in double- or triple-pane windows
- Gaps in framing or flashing from poor installation or age
- Damaged weather stripping that allows air and moisture through
- Clogged weep holes that prevent proper drainage
Whether you're in an older home or a newer office building, these issues worsen in the fall and can lead to costly winter repairs.
How to Fix A Leaking Window This Fall: A Step-by-Step Guide
1. Re-Caulk Window Edges
Remove old, cracked caulk and reseal with an exterior-grade silicone or polyurethane sealant. Be sure to apply a smooth bead around all sides where the window meets the frame. When in doubt, follow the instructions on the sealant tube.
2. Replace Worn-Out Weather Stripping
Choose weather stripping suited to your
window style (foam tape, rubber, V-strip) and replace any flattened or brittle sections.
3. Install Window Insulation Film
Window insulation film is a simple and affordable DIY fix for drafty glass, especially in older single-pane windows. These kits use a plastic film that creates a barrier when heated with a hair dryer.
4. Clear Window Weep Holes
If you’re not familiar with weep holes, they are small openings that are typically found in the base of window frames, designed to allow water to drain out. Use a small wire brush or toothpick to remove dirt and debris from weep holes in your window frame. This will ensure proper drainage and prevent water buildup inside the window.
5. Consider Window Replacement
If your windows are severely damaged, outdated, or repeatedly leaking, replacement may be the most cost-effective solution. Modern,
energy-efficient windows provide superior insulation, protection, and curb appeal.
