Aftercare tips

A little care helps the new joints last. We recommend:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • File the fire-stopping record where your assessor can find it
  • Do not paint over fire sealant until it has cured
  • Photograph sealed gaps before they’re covered up

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so the item can be closed.

About our fire rated sealant in Labour-in-vain

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you have fire seals that have cracked with movement and sealant items on a fire risk assessment action list, we can put it right, on flats & HMOs, service penetrations and door frames alike.

For a small place like Labour-in-vain, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

Each job carries a 12-month guarantee, whatever its size.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.

Landlords and letting agents in Labour-in-vain can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

When it isn’t the sealant

In fairness, some problems need a different trade:

  • Problems with the door itself rather than the gap around the frame
  • Fire risk assessments, which need a qualified assessor
  • Construction that doesn’t provide fire resistance on its own

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

What we seal

  • Linear gaps
  • Plasterboard & masonry
  • Pipe & cable gaps
  • Door frames
  • Flats & HMOs
  • Service penetrations

Why it’s worth doing now in Labour-in-vain

Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. In a small place like Labour-in-vain, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Labour-in-vain questions

Do you cover Labour-in-vain for fire rated sealant?

Yes. We work across London and the South East, and Labour-in-vain is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Can you help a landlord with a rental near Borough Green & Wrotham station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.

Do you remove the old sealant?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Can you fill the gap behind a fire door frame?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

Are you insured?

Yes. Full insurance covers our work.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Commercial buildings in Labour-in-vain

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Community buildings like Church of St George are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Schools such as Wrotham School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

  • Gaps flagged on a fire risk assessment
  • Gaps filled with a product that isn’t fire-rated

Choosing a sealant specialist

What happens on the day

At the end, we look at the finished work together. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Somewhere as small as Labour-in-vain, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your records.
