Fire stopping across Badlesmere

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

Fire stopping in Badlesmere

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with fire-stopping items raised at inspection or handover and open linear gaps along the top of fire-resisting walls, we can help, on cable penetrations, linear gaps at wall heads and service gaps in risers alike. A single leaking joint is often how a building in Badlesmere first comes to us: we look at the rest while we are there and tell you what we find.

Rural conversions around Badlesmere can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Different surfaces, different methods

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.

Common questions from Badlesmere clients

Do you decide the fire-stopping details for buildings in Badlesmere?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

Is Badlesmere too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can you work while the building is occupied?

Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What affects the price in Badlesmere

What shapes the price:

  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • Phasing around occupants
  • Induction, permit and paperwork requirements

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

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

  • Access details, including height
  • When you need the work done
  • Photos of the joints, close up and from further back
  • The site address and postcode

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Badlesmere need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  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.

Getting the site ready

  • Confirm the product named in the specification
  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Related advice

Do you need fire stopping in Badlesmere?

Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Typical triggers for a call:

  • Unsealed joints where partitions meet the slab
  • Fire-rated sealant that has cracked or shrunk back
  • Builders’ foam or ordinary silicone in compartment walls
  • Service penetrations left open after M&E works

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

What your quote should include

  • Will RAMS and insurance details be available?
  • Proof of insurance
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it

Fire stopping around Badlesmere: what changes locally

Badlesmere is about 45 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

In a building such as Church of St Leonard, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Badlesmere is about 4 miles south of Preston, in Kent. We send applicators to Badlesmere for service penetrations. Our Kent coverage takes in 931 places. For work in that direction, see our London page, about 45 miles away.

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Have penetrations checked while they can still be seen
  • Agree the fire-stopping specification before services go in
  • Look above ceilings when tiles are lifted for other jobs
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
