# Repair or Replace? Building a Workwear Maintenance Programme

**Repair when the repair costs less than about 30% of the replacement price and the garment still meets its certification. Replace when reflective tape, fluorescent colour, flame resistance or the compliance marking has degraded, because none of those can be restored in the field. A working programme needs three things: a written decision rule, compliant spare materials in stock, and a repair log that ties every garment back to its inspection record.**

## Key takeaways

- **Repairs are cheap; non-compliant repairs are expensive.** Thread, tape and patches must match the garment's certification.
- **Tape, fluorescent colour and FR finish cannot be repaired** — those failures mean retirement.
- **Set the threshold in writing:** repair under 30% of replacement cost, replace above it.
- **Stock spare parts for the top five failure points** and repairs take minutes instead of weeks.
- **Log every repair**, or you cannot prove the garment is still compliant.

## 1. The decision rule

| Condition | Action | Threshold |
| --------- | ------ | --------- |
| Torn seam or split seam | Repair | If fabric around the seam is sound |
| Failed zip or closure | Repair | If a matching zip is available and the garment is not FR-critical |
| Missing button, press stud or Velcro | Repair | Always, if compliant parts are used |
| Small hole or burn mark | Repair or replace | Repair if under 20 mm and outside a stress area on non-FR garments |
| Reflective tape cracked, dull or peeling | Replace the garment | Never repair |
| Fluorescent colour noticeably faded | Replace the garment | Never repair |
| FR garment with a hole or permanent contamination | Replace the garment | Repairs on FR garments must be approved by the manufacturer |
| Compliance marking illegible | Replace the garment | Marking is part of the certification |
| Repair cost above 30% of replacement | Replace | Economic threshold |

## 2. What can and cannot be repaired

| Component | Repairable? | Conditions |
| --------- | ----------- | ---------- |
| Seams | Yes | Compliant thread; seam type matched to the original |
| Zips | Usually | Matching zip; not on certified protective closures where the zip is part of the certification |
| Buttons and press studs | Yes | Metal-free where metal detection applies; FR-safe where required |
| Elastic | Yes | Heat-resistant elastic for industrial laundering |
| Pockets | Often | Compliant fabric and thread; must not alter the garment's certified construction |
| Reflective tape | No | Field repair cannot restore or verify reflectivity |
| Fluorescent fabric colour | No | Cannot be restored |
| FR finish | No | Cannot be reapplied outside a mill process |
| Arc-rated garment fabric | No | Any fabric repair compromises the rating |

The practical rule for protective garments: the more the repair changes the certified construction, the more likely it is that the garment can no longer be claimed as compliant. When in doubt, ask the manufacturer in writing.

## 3. Repair materials must match the certification

| Garment type | Thread | Patches and fabric | Trims |
| ------------ | ------ | ------------------ | ----- |
| Standard workwear | Polyester core-spun, colour matched | Matching shell fabric | Any commercial-grade equivalent |
| FR garments | FR-certified thread | FR fabric only, approved by the manufacturer | FR-safe, metal-free where required |
| Hi-vis garments | Standard thread is acceptable for seams away from tape | Certified fluorescent fabric where the visible area is affected | Never substitute uncertified tape |
| Anti-static garments | As specified by the manufacturer | Conductive-grid fabric only | Conductive closures where specified |
| Arc-rated garments | As specified by the manufacturer | Repair only if permitted; the rating may be affected | Manufacturer-approved components only |

## 4. Setting up the programme

| Decision | In-house repair | External repair partner |
| -------- | --------------- | ----------------------- |
| Equipment needed | Industrial sewing machine, thread, zips, tape, heat press for transfers | None |
| Cost per repair | Low material cost plus labour | US$3–12 per garment depending on the repair |
| Turnaround | Same day to a few days | One to three weeks including transport |
| Compliance control | You control the materials | Requires a written specification of compliant materials |
| Best for | Large fleets, laundry operations, high repair volumes | Smaller programmes and specialised repairs |

## 5. Spare parts to stock

| Part | Quantity per 100 garments | Notes |
| ---- | ------------------------- | ----- |
| Main zips, matching length and colour | 10–15 | The most common failure point |
| Press studs and buttons | 50–100 | Cheap and quick to replace |
| Thread, colour matched | 2–3 cones | FR-certified thread separately for FR garments |
| Elastic, heat resistant | 10 m | For trouser and jacket hems |
| Certified reflective tape | 5 m | For cases where the manufacturer permits tape replacement |
| Pocketing fabric | 3 m | For pocket repairs |
| Heat transfer repair patches | 20 | For small holes on non-FR garments |

## 6. The repair workflow

- **Tag on removal.** Garments entering repair are tagged with the garment ID and the reported fault.
- **Assess against the decision rule.** Repair or retire, recorded in the log.
- **Repair with compliant materials.** Thread, tape and fabric matched to the garment type.
- **Inspect after repair.** Check the repair, the surrounding fabric and the certification marking.
- **Return to service with a log entry.** Date, repair type, materials used and the inspector's name.
- **Retire what cannot be repaired.** Mark or cut the garment so it cannot re-enter service as PPE.

## 7. Repair versus replace: the arithmetic

| Scenario | Repair | Replace | Better option |
| -------- | ------ | ------- | ------------- |
| Zip failure on a US$60 jacket at month 6 | $8–12 | $60 | Repair |
| Seam repair on US$18 trousers at month 10 | $4–8 | $18 | Repair |
| Hole in coveralls in month 20 | $6–10 | $20–35 | Repair if compliant, otherwise replace |
| Tape degraded on a US$25 hi-vis jacket | Not permitted | $25 | Replace |
| FR garment with a 15 mm hole | Usually not permitted | $45–70 | Replace |
| Permanent oil contamination on FR coveralls | Not effective | $40–65 | Replace |

Across a typical industrial fleet, 40–60% of faults fall into the repairable category. Recovering even half of those instead of replacing them is usually worth 8–15% of the annual workwear budget.

## 8. Common repairs and how to do them properly

| Repair | Correct method | Common error |
| ------ | -------------- | ------------ |
| Split seam | Re-stitch matching the original seam type and stitch density | Overlocking over the original stitching, weakening the seam |
| Zip replacement | Same length, gauge and type; bar tack the ends | Using a shorter or lighter zip that fails again |
| Button or stud replacement | Matching part, correct spacing | Metal parts on garments screened for metal detection |
| Trouser hem | Re-hem to the original length with matching thread | Altering inseam length without recording it |
| Small hole, non-FR garment | Heat transfer patch or matching fabric patch | Iron-on patch on a hi-vis fluorescent area |
| Elastic replacement | Heat-resistant elastic, correct tension | Standard elastic that fails in industrial laundry |

## 9. Downgrading instead of scrapping

| Option | Appropriate for | Requirement |
| ------ | --------------- | ----------- |
| Demote to non-safety use | Garments with cosmetic wear only | Permanently mark the garment so it cannot be reissued as PPE |
| Use for training or visitors | Garments with minor cosmetic defects | Must not be worn where the standard is required |
| Cut and recycle as textile waste | Garments beyond repair | Remove tape, zips and metal where the recycler requires it |
| Dispose of as industrial waste | Contaminated garments | Follow local regulations for PPE waste |

## 10. Programme metrics

| Metric | Target | What it tells you |
| ------ | ------ | ----------------- |
| Repair rate | 40–60% of reported faults repaired | Whether the programme is capturing available savings |
| Repeat repair rate | Under 10% | Repair quality and material suitability |
| Average repair cost | Under 30% of replacement cost | Whether the threshold is set correctly |
| Turnaround time | Under 5 working days in-house | Whether the programme is fast enough to keep crews equipped |
| Cost per wear | Falling year on year | The overall economics of the fleet |
| Retirement rate | 15–25% per year, planned | Whether replacement is budgeted rather than reactive |

## 11. Documentation and audit readiness

- Garment or batch identifier.
- Fault reported, with date and source.
- Decision taken, and by whom.
- Materials used, including thread and tape references.
- Post-repair inspection result.
- Return-to-service date, or retirement date and reason.
- Evidence that retired garments were marked or destroyed.

## 12. Common mistakes

- Repairing reflective tape or FR garments in ways that break the certification.
- Using standard thread on FR garments because it matches the colour.
- Failing to log repairs, leaving no evidence of compliance.
- Setting the repair threshold by habit rather than by cost comparison.
- Returning retired garments to circulation without permanent marking.
- Stocking no spare parts, so every repair becomes a two-week wait.

## 13. Frequently asked questions

### Should workwear be repaired or replaced?

Repair when the cost is under about 30% of replacement and the garment still meets its certification. Replace when reflective tape, fluorescent colour, flame resistance or the compliance marking has degraded, because none of those can be restored in the field.

### Can reflective tape be repaired or replaced?

In practice, no. Tape performance is certified as part of the finished garment, and a field repair cannot restore or verify reflectivity, so a garment with degraded tape should be retired.

### Can FR garments be repaired?

Only with manufacturer-approved methods and materials, and never where the repair affects the certified construction. A hole or permanent contamination normally means retirement rather than repair.

### What thread should be used for repairs?

Colour-matched polyester core-spun thread for standard workwear, and FR-certified thread for flame-resistant garments. Using standard thread on an FR garment can compromise the protection.

### How much does a typical workwear repair cost?

Around US$3–12 per garment externally, and mostly material cost in-house. Zip replacement and seam repairs are the most common jobs and the cheapest to recover.

### How many repairs can a garment take?

There is no fixed limit, but repeated repairs at the same point indicate the garment is at the end of its life. Repair rate above two repairs per garment per year is usually a signal to replace.

### What should happen to garments that cannot be repaired?

They should be permanently marked or cut so they cannot re-enter service as PPE, then recycled or disposed of according to local regulations for protective clothing waste.

### Do repairs affect compliance records?

Yes. Each repair should be logged with the materials used and the post-repair inspection result, because an auditor may ask how a garment remains compliant after modification.
