A garage door is a long-term investment, but like any mechanical system, it won’t last forever.

For UK homeowners, knowing when to repair or replace your garage door can save money, improve security, and prevent breakdowns.
This guide covers:
✔ Average lifespan of garage doors (by material)
✔ Key signs you need repairs vs. replacement
✔ Cost comparisons
✔ How to extend your door’s life
How Long Should a Garage Door Last?
Material | Average Lifespan | Factors Affecting Longevity |
---|---|---|
Steel | 15–30 years | Thickness, insulation, rust prevention |
Aluminium | 15–25 years | Coastal areas (salt corrosion risk) |
Wood | 20–30 years | Maintenance (sealing, staining) |
Fibreglass (GRP) | 10–20 years | UV exposure, impact resistance |
Roller Doors | 10–20 years | Mechanism maintenance, usage frequency |
💡 Note: Well-maintained doors can last 10+ years longer than neglected ones.
5 Signs Your Garage Door Needs Repairs
1. Noisy Operation (Grinding, Squeaking)
- Fix: Lubricate hinges, rollers, and springs.
- If persistent: Worn-out parts may need replacing.
2. Slow Response or Sticking
- Cause: Faulty springs, misaligned tracks, or opener issues.
- Solution: Adjust tracks or replace springs (don’t DIY—dangerous!).
3. Gaps or Drafts
- Problem: Poor sealing increases energy bills.
- Fix: Replace weatherstripping (£20–£50).
4. Dents or Cosmetic Damage
- Steel doors: Can often be repaired.
- Wood doors: May need sanding & repainting.
5. Remote/Opener Malfunctions
- Try first: Replace batteries, reprogram remotes.
- If unresolved: Motor or sensor issues may require professional help.
When Should You Replace Instead of Repair?
🚨 Replace If…
✔ The door is 20+ years old (efficiency & safety decline).
✔ Multiple components fail (springs + tracks + motor).
✔ Severe rust or rot compromises structural integrity.
✔ Frequent breakdowns (costly vs. new door investment).
✔ Security risks (outdated locks, easy forced entry).
💰 Cost Comparison: Repair vs. Replace
Issue | Avg. Repair Cost | Replacement Cost |
---|---|---|
Broken Spring | £80–£200 | N/A (part of system) |
New Motor | £150–£400 | £500–£1,500 (full upgrade) |
Panel Replacement | £100–£300 | £800–£3,000 (new door) |
Full Overhaul | £300–£800 | £1,000–£4,000+ |
💡 Rule of thumb: If repairs exceed 50% of a new door’s cost, replacement is smarter.
How to Extend Your Garage Door’s Lifespan
1. Annual Maintenance Checklist
✅ Lubricate moving parts (silicone spray, not oil).
✅ Tighten bolts, hinges, and track screws.
✅ Test balance & auto-reverse safety feature.
✅ Clean tracks & check alignment.
2. Upgrade Key Components
- Install nylon rollers (quieter, longer-lasting than metal).
- Replace weatherstripping every 5 years.
- Opt for a belt-drive opener (quieter than chain drives).
3. Protect Against UK Weather
- Steel doors: Apply anti-rust treatment.
- Wood doors: Re-stain/seal every 2–3 years.
- All doors: Ensure drainage to prevent water pooling.
Final Decision: Repair or Replace?
🔧 Choose Repair If:
- The door is under 15 years old.
- Only one component is faulty.
- Costs are under £500.
🔄 Choose Replacement If:
- The door is old, inefficient, or unsafe.
- You face multiple recurring issues.
- A modern, insulated door would save energy.
