What fire rated sealant looks like in Markbeech

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

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

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • Access and height
  • The product the joint needs
  • The number and length of the joints
  • When we can work, for business premises

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

What to tell us for a quote

To help us quote quickly, let us know:

  • Roughly how big the job is
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that’s easy

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Leave it or put it right?

For some gaps, sealant isn’t the right answer and another system is needed. 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. Around Markbeech, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Questions from Markbeech

Is Markbeech in your area for fire rated sealant?

Yes. We work across London and the South East, and Markbeech is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Cowden station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Do you take on fire stopping in schools and offices?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

How long does fire rated sealant take?

As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we will say how long yours will take.

What does intumescent mean?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Do you need fire rated sealant in Markbeech?

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

It’s worth asking for a quote if you see:

  • Ordinary sealant used where a fire-rated product was needed
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps left after a refit or conversion
  • Seals cut through by electricians, plumbers or data installers

For landlords with property near Cowden station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before you book

  • How much experience the applicator has
  • Whether all the old sealant comes out first
  • The length of the guarantee
  • Whether they’re fully insured

10 questions to ask before you book

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Include hidden areas like risers in routine checks
  • Flag any open gap you spot round a pipe or cable
  • Photograph sealed gaps before they’re covered up
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

How it works

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Markbeech, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
