Fire rated sealant in North Marston

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. Common call-outs are for gaps flagged on a fire risk assessment and fire stopping disturbed by later work, across plasterboard & masonry, linear gaps and door frames.

For holiday lets, converted business premises or a community building near North Marston, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

FAQs for North Marston

Do you cover North Marston for fire rated sealant?

Yes. Our work covers London and the South East, and North Marston is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Do you work for landlords with property near Aylesbury Vale Parkway station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Will we have a record of what was sealed?

Yes. We record the locations we have sealed and the products used.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

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.

Can ordinary silicone be used in a fire-stopping gap?

No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.

What fire rating will the seal have?

That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.

What we can’t put right

In fairness, there are a few things sealant will not fix:

  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system
  • A wall that isn’t a fire-resisting element to begin with

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

What we seal

  • Flats & HMOs
  • Service penetrations

Fire rated sealant around North Marston

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.

For site and facilities teams at buildings such as North Marston Church of England School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Aylesbury Vale Parkway station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like North Marston, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises

Related advice

Different surfaces, different methods

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.

What we are called out for in North Marston

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

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

  • Old fire sealant that has split or come away
  • Holes left by a change of layout
  • Damaged fire sealant left by other trades
  • Sealant items on a fire risk assessment action list

Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Our hiring checklist

DIY sealant or a professional job?

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.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What affects the cost of fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • Mould in or behind the old joints
  • The type of sealant required
  • How much there is to do
  • Whether the work is at height

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Access, such as stairs, a lift or height
  • Where the property is
  • Roughly how big the job is
  • What’s wrong with the joints now

To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Allow for resealing whenever new services are run
  • Get damaged fire seals looked at promptly
  • Check risers, ceiling voids and cupboards during building checks
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
