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.

Sometimes the door is not the real problem. The opening around it may be out of square, the flashing may be incomplete, or the sill pan may never have been built to manage water correctly in the first place.
