About our fire stopping in Nash

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are improvised or mixed-product fire seals and fire-rated sealant that has cracked or shrunk back. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Nash, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Nash 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

After the work

To get the most from the new sealant:

  • Treat an open penetration as a priority repair
  • Check with the data sheet before painting over fire sealant
  • Ask the designer to confirm details early on refits
  • Keep general-purpose fillers away from compartment walls

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Fire stopping around Nash: what changes locally

For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 60 miles from central London, Nash is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Hospital estates such as St Martins Hospital, 6 miles west of Nash, 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 Wingham Industrial Estate, which lies south-west of Nash, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Nash is about 7 miles east of Canterbury, in Kent. We send applicators to Nash for service penetrations, handled exactly as we handle every other area. Nash is one of 931 places we cover in Kent. London is covered too, around 60 miles from Nash.

Commercial sites across CT3 are covered. Just outside Nash, we also work in Hoaden (1 mile north-east), Perry (1 mile west), Shatterling (1 mile south-west), Elmstone (1 mile north) and Durlock (1 mile south-east). Further afield, our area takes in Canterbury (7 miles west), Margate (9 miles north-east), Dover (10 miles south), Folkestone (14 miles south), Ramsgate (8 miles north-east) and Broadstairs (10 miles north-east).

Local landmarks in Nash

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.

Do you need fire stopping in Nash?

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Most enquiries start with one or more of the following:

  • Fire sealant pulled out of the opening
  • Unsealed joints where partitions meet the slab
  • Improvised or mixed-product fire seals
  • Unsealed openings around new pipes and cables

For a building such as Elmstone Church, new heating or data runs are the usual reason penetrations need sealing.

  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Nash, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Confirm the product named in the specification
  • Arrange parking or a loading space
  • Let us know about inductions and permits

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • Phasing around occupants
  • Any access equipment needed

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • The product your specification calls for

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or use the quote form.

Questions about Nash

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

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.

Do you take on work at healthcare sites like St Martins Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it.
