However in some instances the top corner of the door is the true culprit.
Masonite french doors leak.
The astricle that meets the doors in the middle allows rain wind and other elements inside.
Whether you choose wood fiberglass or steel construction every masonite exterior door is the result of years of research design engineering and development.
Sliding doors overlap which is a more energy efficient design and creates a tighter seal.
Without proper sealing french doors also serve as a notorious source of water leaks.
However french doors come together with no overlap and an increased chance for air infiltration.
Moisture could be seeping into your home from the top.
Left untreated these water leaks can damage your flooring and may even rot the doors and surrounding.
Whether your door is sagging or bowed or just not making proper contact with the weatherstrip to seal out air and water the upper corners of your frame could be the problem.
The seal around the doors and in the middle is just a bad design.
When a door leaks the most common suspect is the bottom corner of the unit.
I had masonite french doors installed three years ago.
Also as winds blows against a french door it tends to bow causing additional air leakage.
