Waterproofing for French Doors

Save

Waterproofing leaky French doors help protect the doors and your home from water damage, mold and mildew. This project also seals up air leaks that can make the interior temperature difficult to control, resulting in higher energy costs. Protecting French doors against water penetration can include weatherstripping, new threshold seals, and sealing cracks in the doors.

Door Frame

  • Cracks or gaps in the door frame can allow water penetration during storms or heavy rain. Wood filler or waterproof, shrink/crack-proof silicone caulk can be used to fill cracks or gaps around the edge of the frame. Spray foam insulation should be used to fill larger gaps or holes.

Doors

  • Broken or water-damaged doors should be repaired or replaced. Wood filler or caulk can be used to fill cracks or gaps where sections of the door have separated. Caulk applied around the edge of glass panels helps seal the gaps. A coat of exterior paint or water sealant adds further protection.

Weatherstripping

  • Installing new, or replacing worn weatherstripping along the top and sides of the door improves the seal between the door and frame, preventing water penetration. It also prevents air loss and improves the energy efficiency of the door. A self-sealing door threshold provides a water barrier between the bottom of the door and the threshold.

Hardware

  • Rubber gaskets can be installed in the door handle assembly and locking mechanism to reduce water penetration, and prevent rust or corrosion of working parts. Loose hinges should be tightened to ensure proper alignment of the door. Misaligned doors do not provide a tight seal, and are prone to water leakage.
