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

Why Water Gets Under Patio Doors In A Storm

If you find water pooling under a patio door after a hard rain, the door itself may be part of the issue, but the wall, threshold, or drainage details often play a role too.

During summer storms and hurricane weather, water can push past worn weatherstripping, a low or damaged threshold, gaps at the sill pan, or failed sealant at the frame perimeter.

A clogged exterior drainage path, a missing or damaged sill pan, settlement that throws the frame slightly out of square, or cracked caulk at the outside trim can all let water travel inward.

If the original installation was rushed, or if the replacement did not follow the manufacturer's instructions, the door can look fine on a dry day and still fail when wind pushes rain hard against it.
