We have the Pella sliding french doors, still working great after 14 years of use. Like the PP said, what is the cause of the leakage? If they only leak when it's raining and a 40 mph wind blowing the rain under the door, then it's probably the door threshold or door seals. Otherwise, look for drainage issues.
