Your door has been damaged—forced in a break-in, hit by something heavy, or just finally failed after years of wear. Now you face a decision: repair what you have, or replace it entirely?
This guide helps you make the right choice based on damage type, cost, security, and practical factors. For immediate post-incident steps, see our after a break-in guide.
Repair when: Damage is superficial, frame is sound, and the door has remaining life. Replace when: Structural integrity is compromised, security is inadequate, or repair costs approach replacement costs. For break-in damage, replacement often makes sense—both for security and peace of mind.
Assessing the Damage
Damage to the Door Itself
| Damage Type | Repair Possible? | Notes |
|---|---|---|
| Lock mechanism damage | Usually | Replace lock, keep door |
| Surface scratches | Yes | Cosmetic repair |
| Dents in steel/composite | Sometimes | Depends on severity |
| Cracked panels (cosmetic) | Yes | Fill, sand, paint |
| Split stiles or rails | Rarely | Structural weakness |
| Warped door | Rarely | Won’t seal properly |
Damage to the Frame
| Damage Type | Repair Possible? | Notes |
|---|---|---|
| Lock keep area splintered | Often | Reinforce with metal plate |
| Hinge area damaged | Sometimes | May need new hinge position |
| Frame split along length | Rarely | Structural failure |
| Frame pulled from wall | Yes but complex | Major work required |
When Repair Makes Sense
Good Candidates for Repair
✅ Lock damaged but door and frame intact
✅ Surface damage only (scratches, minor dents)
✅ Strike plate area splintered but frame sound
✅ Hinges damaged but hinge positions usable
✅ Door relatively new with significant life remaining
Repair Advantages
| Advantage | Explanation |
|---|---|
| Lower cost | Typically cheaper than replacement. See when to repair vs replace |
| Faster | No manufacturing lead time |
| Less disruption | Quicker installation |
| Retain character | Keep original door if valued |
Repair Limitations
- Can’t improve door security level
- May be visible evidence of repair
- Underlying weaknesses may remain
- Problem may recur
When Replacement Makes Sense
Strong Cases for Replacement
✅ Structural damage (split, warped, cracked through)
✅ Frame also significantly damaged
✅ Door already aging/worn before incident
✅ Security upgrade wanted anyway
✅ Insurance covering full replacement
✅ Psychological need for “fresh start”
Replacement Advantages
| Advantage | Explanation |
|---|---|
| Full security | New door, new locks, known condition. See front door security |
| Warranty | Manufacturer and installer guarantees |
| Upgrade opportunity | Better security, appearance, efficiency |
| Peace of mind | No hidden damage, clean slate |
Replacement Considerations
- Higher initial cost
- Lead time for custom/specialist doors
- Installation disruption
- Matching existing architecture
Cost Comparison
Typical Repair Costs
| Repair Type | Approximate Cost |
|---|---|
| Lock replacement only | £80-200 |
| Strike plate reinforcement | £50-100 |
| Minor frame repair | £100-200 |
| Significant frame repair | £200-400 |
| Door surface restoration | £100-300 |
Typical Replacement Costs
| Door Type | Supply + Fit Cost |
|---|---|
| Basic uPVC | £400-800 |
| Quality composite | £800-1,500 |
| Solid timber | £600-2,000+ |
| Specialist/period | £1,500-5,000+ |
The Cost-Benefit Calculation
Consider replacement when:
- Repair costs exceed 50% of replacement
- Door has limited remaining life anyway
- Security upgrade is also needed
- Insurance will fund replacement
Insurance Considerations
What’s Typically Covered
Buildings insurance usually covers:
- Repair or replacement of damaged doors
- Associated frame work
- Lock replacement
- Reinstatement to pre-incident condition
Repair vs Replacement Decision
Insurers may:
- Prefer repair if cheaper and adequate
- Accept replacement if repair impractical
- Require quotes for both options
- Have approved contractor networks
Process:
- Get assessor view (if required)
- Obtain repair and replacement quotes
- Submit to insurer for approval
- Proceed only when agreement confirmed
Betterment Rules
If replacement provides improvement over original (newer, better security), insurers may:
- Deduct for “betterment”
- Pay equivalent of like-for-like only
- Require you to pay difference
Security Upgrade Opportunities
If Repairing
While the door is being worked on:
- Upgrade to BS3621 locks if not fitted
- Add hinge bolts
- Install security chain or limiter
- Fit reinforced strike plates
- Add door viewer
If Replacing
Specify upfront:
- Multipoint locking (composite/uPVC)—see multipoint locks explained
- Anti-snap cylinders as standard—see anti-snap cylinder guide
- PAS 24 security testing
- Quality hinges with anti-lift pins
- Appropriate door thickness
Breaking the Cycle
If your door was forced once, upgrading security reduces chances of repeat:
- Burglars note easy-target houses
- Same weakness may be exploited again
- Upgraded security sends different message
Timeline Expectations
Repair Timeline
| Stage | Timeframe |
|---|---|
| Assessment | Often same day - 2 days |
| Parts sourcing | Immediate - 1 week |
| Repair work | 1-3 hours typically |
| Total | 1-7 days |
Replacement Timeline
| Stage | Timeframe |
|---|---|
| Surveying and ordering | 1-3 days |
| Manufacturing (standard) | 1-2 weeks |
| Manufacturing (custom) | 3-6 weeks |
| Installation | 2-4 hours |
| Total | 1-6 weeks |
Living with Temporary Security
During the wait:
- Professional boarding provides security
- Alternative entry points remain usable
- Regular checking of temporary measures
Making Your Decision
Ask Yourself:
-
Is the door structurally compromised?
If yes → Replace -
Is the frame damaged?
If significantly → Likely replace both -
Was the door near end of life anyway?
If yes → Replace makes sense -
Is security adequate, or did this incident expose weaknesses?
If weaknesses exposed → Consider upgrade -
What will insurance cover?
If replacement covered → Why not take the opportunity? -
How do you feel about the damaged door?
If it will always remind you → Replace for peace of mind
The Right Choice
There’s no universal answer—it depends on damage extent, door condition, insurance situation, and your priorities. But the decision is worth making thoughtfully:
- Quick repair gets you secure fast but may leave issues
- Thorough replacement takes longer but resolves everything
When security is involved, doing it right matters more than doing it fast. Take the time to assess properly, involve your insurer (see our insurance claims guide), and make a decision that leaves your property genuinely secure—not just patched.
