Fire stopping for Teynham Street sites

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

Why act early in Teynham Street

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Halls, stores and units around places like Teynham Street may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

About our fire stopping in Teynham Street

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve fire sealant pulled out of the opening and snag lists that include open service penetrations, on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors. For commercial sealant work in Teynham Street, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller places such as Teynham Street 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Commercial clients in Teynham Street

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Teynham Street are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  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

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Arrange parking or a loading space

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Removal of failed or old sealant

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • The site address and postcode
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or send photos by email.

Penetration seals near Teynham Street

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. What we install is set by the specification, and it goes in to the tested detail. At about 41 miles from central London, Teynham Street is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

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

When to call us in Teynham Street

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.

If one of these sounds familiar, it’s time for a closer look:

  • Builders’ foam or ordinary silicone in compartment walls
  • Hidden openings found during inspections
  • Head-of-wall gaps with no fire seal
  • Service penetrations left open after M&E works

In a school such as Teynham Parochial Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Questions to ask before you book

  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • Health and safety accreditation such as CHAS

Questions about Teynham Street

Is a smaller place like Teynham Street outside your area?

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

Can you produce the fire-stopping design for a job in Teynham Street?

No. The designer or fire engineer sets the detail and building control accepts it. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

Will you just go over the old sealant?

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

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Treat an open penetration as a priority repair
  • Agree the fire-stopping specification before services go in
  • Ask which product is in place before decorating
  • Put resealing into every M&E and fit-out package

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
