How to Stop Water Leaking Under Patio Doors During Brandon FL Storms

If a patio door starts leaking at the bottom during a Brandon storm, the rain is usually exposing a weak point that has been there for a while. Wind pressure, a worn threshold, blocked weep paths, or bad flashing can all let water come in under the track instead of off the exterior side of the door.

Why Patio Doors Leak At The Bottom During Storms

The bottom of the patio door is usually where leaks begin. A worn seal, poor threshold slope, or a gap at the frame lets water bypass the door assembly and move inside when the rain is being driven sideways.

Blocked drainage is a frequent problem on patio doors. If the weep system cannot clear water fast enough, the door track fills up during a storm and the water eventually overflows where it should not.

Signs The Patio Door Needs More Than A Patch
