With over 20 years of experience, we know exactly how water intrusion occurs around patio doors—and how to fix it right the first time.​

Why Do Patio Doors Leak?

Patio door leaks are often caused by:
  • Faulty installation or aging caulking
  • Worn-out or poorly sealed flashing
  • Insufficient flashing or a lack of Door Pan
  • Cracked stucco or siding near the door frame
  • Improper slope or drainage on balconies or decks
​
These issues can allow water to seep into walls and flooring, leading to mold, rot, and expensive structural repairs if left unaddressed.
