Fire stopping for Margate sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a town like Margate, we try to group jobs for the same client into one visit. Tell us when the building is open and we will plan to suit.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Make sure the joints can be reached
  • Flag any permit to work we’ll need
  • Send your site hours and access windows

Fire stopping in Margate

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the failures we are asked to look at most are service penetrations left open after M&E works and snag lists that include open service penetrations. A single leaking joint is often how a building in Margate first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Many town-centre buildings in places like Margate have had layer upon layer of new services, with gaps around pipes and cables left after each change. Intumescent or fire-rated sealant is used wherever the specification asks for it, built up exactly as tested.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Look above ceilings when tiles are lifted for other jobs
  • Get seals inspected before ceilings and boxing close
  • File the specified details where the next contractor can find them
  • Treat an open penetration as a priority repair

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire doors, dampers or other fire safety equipment
  • Signing off or certifying a building’s fire stopping

If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

  • Pipe penetrations
  • Cable penetrations
  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Service gaps in risers
  • Joints between fire-resisting walls and floors

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Fire stopping in Margate: the local picture

At about 64 miles from central London, Margate is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. The area within 2 miles of Margate holds plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Hospital estates such as Queen Elizabeth The Queen Mother Hospital, less than half a mile south-east of Margate, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Where a unit on an estate such as All Saints Industrial Estate, which lies north-west of Margate, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Margate is in Kent. Businesses, contractors and managing agents in Margate can call on us for service penetrations. 931 places across Kent fall within our area, including Margate. Sites around London have their own page, roughly 64 miles from Margate.

FAQs: Margate

What does the BS 476 change mean for fire-rated sealant in Margate?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Will you plan work around the academic year at somewhere like TOPS Vocational College?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you work while the building is occupied?

Normally, yes. We phase the work so most of the building stays in use.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Signs you need fire stopping in Margate

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

What tends to prompt an enquiry:

  • Seals that don’t match their tested detail
  • Expanding foam used as fire stopping
  • Snag lists that include open service penetrations
  • Service penetrations left open after M&E works

For a site team at a college like TOPS Vocational College, 0.5 miles north-east of Margate, fire-rated sealing is best scheduled after the summer works.

Our contractor checklist

Surface by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.
