Fire stopping across Brabourne

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers
  • Any access equipment needed
  • Working within restricted access windows

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • The type of building and who uses it
  • The asbestos register, for older buildings
  • When you need the work done
  • The postcode of the building

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email us.

About our fire stopping in Brabourne

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints 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. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve seals that don’t match their tested detail and fire-rated sealant that has cracked or shrunk back, on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Brabourne from the first photos to the final walk-round, for single jobs and planned programmes alike.

Barn and farm-building conversions near places like Brabourne often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Have penetrations checked while they can still be seen
  • Include service cupboards in routine inspections
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Flag new cables with no seal around them

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Questions about Brabourne

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

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.

Is Evegate Business Park, near Brabourne, within your area?

Yes. We cover Brabourne and the area around it, including industrial estates, business parks and retail parks such as Evegate Business Park. A few photographs and the unit address let us price the work.

What will the job cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Fire stopping in Brabourne: 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. We install whatever has been specified, to the product’s tested detail. Brabourne lies roughly 53 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

For a building at a site such as Evegate Business Park (2.4 miles south-west of Brabourne), a check of penetration seals after each fit-out is good practice. Wherever services are added at a hospital such as William Harvey Hospital, 3.6 miles to the west of Brabourne, the compartment line has to be made good with the specified product.

Brabourne is about 6 miles east of Ashford, in Kent. Looking for fire stopping in Brabourne? We can help, as we do across Kent. Brabourne is one of 931 places in Kent on our list. There’s a separate page for London, roughly 53 miles from Brabourne.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Brabourne, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Advice

Site staff or a sealant specialist?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Do you need fire stopping in Brabourne?

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

What tends to prompt an enquiry:

  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed penetrations discovered above suspended ceilings
  • Seals disturbed by maintenance and left open
  • Open linear gaps along the top of fire-resisting walls

Schools such as Brabourne Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing
  • Will failed sealant be removed rather than covered?
