Fire stopping across Hawkhurst

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

How we handle fire stopping in Hawkhurst

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Hawkhurst. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations, and the failures we’re asked to look at most are penetration schedules that need working through and head-of-wall gaps with no fire seal. For commercial sealant work in Hawkhurst, you deal with one contact from quote to sign-off, whether it’s one building or several.

Converted and extended buildings around places like Hawkhurst can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

Our workmanship is guaranteed for 12 months, in Hawkhurst as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs

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. If neighbouring businesses or buildings around Hawkhurst need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. The specification and schedule come first, so we know which details apply.
  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.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Flag any permit to work we’ll need
  • Point out any areas we must not close
  • Have the specification and drawings to hand

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Agree the fire-stopping specification before services go in
  • Don’t let anyone top up a fire seal with the wrong product
  • Look above ceilings when tiles are lifted for other jobs
  • Get seals inspected before ceilings and boxing close

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

Signs you need fire stopping in Hawkhurst

Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.

Look out for the following:

  • Fire-stopping items raised at inspection or handover
  • Hidden openings found during inspections
  • Head-of-wall gaps with no fire seal
  • Service penetrations left open after M&E works

Holiday works at schools like Hawkhurst Church of England Primary School often leave service openings to seal before pupils return.

Before you book anyone

  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • What the guarantee covers, and for how long
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Surface by surface

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

Cost factors for service penetrations

We price every job individually. The things that drive the figure:

  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • The postcode of the building
  • Your programme or deadline
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, phone 01277 525 020 or email drawings and photos.

Your questions answered

Is Hawkhurst too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you take on work at estates like Hawkhurst Station Business Park, close to Hawkhurst?

Yes. Estates, retail parks and business parks around Hawkhurst, Hawkhurst Station Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Will you sign off the seals for us?

No. Approval sits with the designer, principal designer or building control. We’ll confirm the product and detail installed.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How do we ask for a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or use the quote form. Include photos or drawings if you have them.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Fire-rated sealing for Hawkhurst buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Hawkhurst lies roughly 41 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Tenant changes at parks like Hawkhurst Station Business Park (to the north of Hawkhurst) bring new data and services, and openings through fire-resisting walls need the specified seal. Older community buildings such as Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
