The short answer
Inspect the Window Well
Before touching the window itself, clear out the egress window well. Leaves, soil, and mulch can block drainage and hold water against the glass and frame. Use a shovel or shop vacuum to remove debris down to the gravel or drain tile.
Check the drain at the bottom of the well. If it is clogged, water can pool and seep through the window sill. Run a garden hose into the well briefly to see if water drains away. If it backs up, clear the drain line or extend it away from the foundation.
Check the Sealant and Flashing
Examine the caulk or sealant around the window frame, especially along the top and sides. Cracks or gaps allow rainwater to enter. Also look at the metal flashing above the window; it should overlap the frame and direct water outward.
If you spot damaged sealant, remove the old caulk with a putty knife and clean the surface. Apply a fresh bead of exterior-grade, paintable silicone or polyurethane sealant. Smooth it with a wet finger. For flashing issues, you may need a professional to re-flash the window.
- Look for cracked or missing caulk
- Check if flashing is bent or pulled away
- Inspect the window frame for rot or rust
- Feel around the sill for dampness after rain
- Note any water stains on the drywall below
Examine the Window Panes and Weep Holes
Inspect the glass panes for cracks or gaps in the glazing compound. A cracked pane can let water in. Also find the weep holes at the bottom of the window frame; these allow trapped water to escape. If they are blocked, water can back up and overflow inside.
Use a small wire or toothpick to gently clear the weep holes. Avoid enlarging them. If the window is old or the frame is warped, consider replacing the window entirely. New egress windows often have better drainage and insulation.
Address Interior Water Damage
If water has already leaked inside, dry the area quickly. Remove wet carpet, padding, or drywall if it is saturated. Use fans and a dehumidifier to speed up drying. Mold can develop within 24 to 48 hours, so act fast.
For significant water damage, local water damage pros can extract standing water, dry the structure, and repair drywall or subfloor. They can also perform moisture mapping to find hidden dampness. Do not leave wet materials in place, as that invites mold growth.
Know When to Call a Pro
If the leak is more than a minor sealant issue, or if you see rot, rust, or structural damage, you need professional help. Water can travel along framing and cause damage far from the window. A pro can assess the extent and recommend repairs.
In Rockwall, spring thunderstorms and hail can worsen window leaks. If you suspect the leak is due to poor installation or foundation settling, a window replacement or water damage inspection service can help. For ongoing leaks, a leak detection service can pinpoint the entry point.
- Rot or soft spots in the window frame
- Water stains spreading on walls or ceiling
- Mold or mildew smell in the room
- Multiple failed attempts to reseal
- Leak recurs after heavy rain

Can I fix a leaking egress window myself?
For simple sealant cracks or clogged weep holes, yes. Clean the area, apply new caulk, and keep the well clear. But if the leak comes from flashing, rot, or structural movement, you need a professional. Misdiagnosing can lead to more damage.
How long does it take to repair a leaking egress window?
A minor reseal can take a few hours. If the window needs replacement or structural repair, it may take a day or more. The pros will work at a pace that ensures the repair holds, but you can speed things up by clearing the area beforehand.
Will my insurance cover window leak repairs?
Policies vary, and your insurer decides what is covered. Water damage from a sudden storm might be covered, but gradual leaking from poor maintenance may not be. Check your policy and document the cause and damage. Your insurer will determine coverage.
