Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine, with 7,000+ installations completed since 2011. French doors typically need replacement after 15 to 20 years of regular use — watch for foggy glass, sticking hinges, or drafts around the frame.
Signs It’s Time for New French Doors
- Foggy or Cloudy Glass: Broken seals let moisture between the panes, and clarity never returns.
- Sticking or Dragging Panels: Warped frames signal water damage or age-related wood swelling.
- Cold Drafts Near the Frame: Worn weatherstripping lets outside air slip past the seal.
- Sun-Faded or Cracked Wood: UV exposure breaks down finishes and weakens the panel core.
- Durability Concerns: Durability and longevity rank as the top priority for 100% of surveyed door contractors.
Fiberglass vs. Wood French Door Options
Top Recommendation: Fiberglass French doors from ProVia for lasting strength in a lake climate.
Best for Budget: Steel entry-style French doors for a lower upfront cost.
Best for Classic Style: Custom wood-look fiberglass panels that mimic real grain without the upkeep.
