Does Firestopping Expire?

Does Firestopping Expire? What Contractors and Building Managers Need to Know

It’s a question we’re often asked by building managers, contractors, and property owners: does firestopping expire? The answer isn’t a simple yes or no — but it’s definitely something every duty holder needs to understand.

✅ Firestopping Products: Built to Last — But Not Forever

Firestopping systems (like sealants, collars, wraps, and intumescent materials) are designed to resist fire for a specific period — usually 60, 90, or 120 minutes. But their effectiveness depends on:

• Correct installation by trained professionals

• Approved materials with third-party certification

• Ongoing protection from damage, moisture, or tampering

  
  

While the installed materials themselves don’t have an “expiry date” like food or medicine, they can degrade or become ineffective over time — especially if disturbed during refurbishments or hidden in voids no one checks.

🔍 What Can Go Wrong Over Time?

• Cracks or shrinkage in fire-rated sealants

• Mechanical damage (e.g., from retrofitted cables or pipes)

• Moisture ingress leading to material failure

• Unapproved patch repairs that compromise integrity

• Label loss, making it impossible to trace or certify

  
  

🧯 So… What Should You Do?

1. Get a professional inspection. If you’re unsure about the condition or coverage of firestopping in your building, a survey by a certified team (like R2R’s) can identify issues.

2. Keep good records. Proper documentation helps track installation dates, product types, and maintenance — all critical for compliance under the Building Safety Act.

3. Don’t DIY repairs. Firestopping systems should always be maintained and repaired by trained and third-party accredited professionals.

📌 The Bottom Line:

Firestopping doesn’t “expire” on a specific date — but it absolutely can become ineffective. Regular inspections, quality installations, and a proactive maintenance plan are essential to keep your building protected and compliant.
