Trusted fire rated sealant in Mystole

How we handle fire rated sealant in Mystole

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have damaged fire sealant left by other trades and open holes round services passing through fire walls, we can put it right, whatever the surface.

For a small place like Mystole, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

There’s a 12-month guarantee on every job, whatever its size.

What happens if it’s left?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Where a wall is exposed, as many are in small places like Mystole, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Include fire stopping when you schedule refits
  • Photograph sealed gaps before they’re covered up
  • Do not paint over fire sealant until it has cured
  • Include hidden areas like risers in routine checks

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.

What happens on the day

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Mystole, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Keep children and pets away from the work area
  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints

What sealant work can’t fix

We’d rather tell you now than do work that will not last, so these are the limits:

  • Fire doors that need new seals, closers or hardware
  • Walls or floors that weren’t built to resist fire
  • Certifying a building or signing off its fire safety

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

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

Common problems we fix in Mystole

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried.

These are the problems we’re asked about most:

  • Gaps filled with a product that isn’t fire-rated
  • Linear gaps at the head of walls
  • Fire stopping disturbed by later work
  • Open gaps behind door architraves

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

What your quote should include

  • Whether they’re fully insured
  • Who does the work, and how experienced they are

How to choose a mastic man

What the job involves on each surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment, flat by flat if needed.

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Yes. We work across London and the South East, and Mystole is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.

Is intumescent sealant the same as fire-rated sealant?

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 take on fire stopping in schools and offices?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged if that suits the building.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Are you insured?

Yes. We are fully insured.

Can I choose the sealant colour?

Generally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

What fire rated sealant looks like in Mystole

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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For site and facilities teams at buildings such as Chartham Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building.
