The short answer
Start with the Weep Holes
Weep holes are small openings at the bottom of the window frame that let water escape to the outside. If they get clogged with dirt, paint, or debris, water backs up and spills into your home. Use a small wire or compressed air to clear them gently. Check them at least twice a year, especially after storms.
Also, inspect the drainage slots along the bottom track. They can become blocked by leaves or insect nests. Keep the track clean and clear of obstructions. If the window has a screen, remove it to access the track easily. A simple cleaning often solves the problem without any repairs.
Check the Sealant and Flashing
The sealant around the window frame can crack, shrink, or pull away over time. That creates gaps where water can enter. Inspect the caulk or silicone bead on the exterior of the frame. Look for cracks, holes, or areas that feel soft. If you find damage, remove the old sealant and apply a fresh bead of exterior-grade caulk.
Flashing is the metal or plastic strip that directs water away from the top and sides of the window. If it is loose or missing, water can run behind the siding. Check that the flashing is securely attached and slopes downward. If you are unsure about the condition, a water damage inspection can help identify the exact entry point.
- Clear weep holes with a wire or air duster
- Remove debris from the bottom track
- Inspect exterior caulk for cracks or gaps
- Check flashing for proper slope and attachment
- Look for water stains on the interior sill
- Test the window by pouring a small amount of water on the exterior
Look at the Window Sill and Frame
The window sill should slope downward away from the glass so water runs off, not into the wall. Over time, the sill can rot or warp. Use a level to check the slope. If it is level or slopes inward, water will pool. You may need to add a drip edge or replace the sill if it is badly damaged.
The frame itself can also be the problem. If the window is old or poorly installed, gaps between the frame and the wall can let water in. Look for daylight around the edges from inside. If you see gaps, filling them with expanding foam or caulk can help. For major issues, window replacement might be the long-term fix.
Consider the Roof and Gutters
Sometimes a window leak is not really a window problem. Overflowing gutters or a damaged roof can send water down the wall and into the window area. Check that gutters are clear and downspouts direct water away from the foundation. If you have a roof leak, that water can travel along framing and appear at the window.
Inspect the roof for missing shingles or damaged flashing near the window. A roof leak repair may be necessary if you see signs of water on the ceiling or walls. If you are unsure, a water damage inspection can trace the moisture back to its source. Do not ignore the possibility that the leak originates higher up.
When to Call the Pros
If you have cleaned the weep holes, checked the sealant, and verified the sill slope, but the leak persists, it is time to involve the pros. A water damage inspection can use moisture meters to find hidden water and determine the exact entry point. That information guides the right repair, whether it is a simple reseal or a full window replacement.
In Rogers, window leaks can stem from a variety of causes, and a professional assessment helps avoid guesswork. If water has already damaged the interior drywall or framing, you may need structural drying to prevent mold. The pros can also help with drywall repair after the leak is fixed. Acting quickly reduces the risk of further damage.
- Persistent leaks after basic maintenance
- Visible rot or warping on the frame or sill
- Water stains on the interior walls or ceiling
- Signs of mold or mildew near the window
- Recent heavy storms that caused leaks

Why does my window leak only during heavy rain?
Heavy rain can overwhelm the weep holes or drainage system, especially if they are partially clogged. Wind-driven rain can also force water past the sealant. Check the weep holes and the exterior caulk. If the problem only happens in storms, the flashing may be inadequate for that amount of water.
Can I fix a window leak myself?
Yes, for simple issues like clogged weep holes or cracked caulk, you can do the repair yourself with basic tools. Clean the tracks and replace the sealant. However, if the leak is due to structural issues like a damaged frame or flashing, you may need professional help. A water damage inspection can confirm the cause.
What should I do if water has already damaged the wall?
First, dry the area thoroughly to prevent mold growth. Use fans or a dehumidifier to remove moisture. If the drywall is soft or stained, it may need to be cut out and replaced. Consider a water damage inspection to assess the extent. Then, address the window leak to prevent recurrence.
