Need fire stopping in Westwell Leacon?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What the job involves on each surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.

About our fire stopping in Westwell Leacon

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve penetration schedules that need working through and unsealed joints where partitions meet the slab, on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors. Looking for mastic applicators who cover Westwell Leacon? We have been sealing commercial buildings since 2005.

Smaller places such as Westwell Leacon still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Writing the fire-stopping specification
  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Surfaces we seal

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

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Westwell Leacon are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

Aftercare for building managers

For the best life from the joints:

  • Look above ceilings when tiles are lifted for other jobs
  • Don’t let anyone top up a fire seal with the wrong product
  • Record which product was used where
  • Put resealing into every M&E and fit-out package

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Fire stopping in Westwell Leacon: the local picture

Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Westwell Leacon is about 44 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Schools such as The Hayesbrook School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a building such as Charing Methodist Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Common problems we fix in Westwell Leacon

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

Look out for the following:

  • Unsealed joints where partitions meet the slab
  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed penetrations discovered above suspended ceilings
  • Seals that don’t match their tested detail

Wherever services are added at a hospital such as William Harvey Hospital, 5.9 miles south-east of Westwell Leacon, the compartment line has to be made good with the specified product.

Questions to ask before you appoint anyone

Westwell Leacon: questions and answers

Would you work within a site like William Harvey Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
