Fire stopping across Albourne Street

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

How we handle fire stopping in Albourne Street

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Albourne Street. We work on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows, and what we’re called in for most is openings found when ceilings come down for a refit and fire seals cut back for extra cables and never reinstated. A single leaking joint is often how a building in Albourne Street first comes to us: we look at the rest while we are there and tell you what we find.

Smaller places such as Albourne 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.

Building owners and contractors get the same cover: 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.

Fire-rated sealing for Albourne Street buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. At about 39 miles from central London, Albourne Street is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

In a school such as Albourne CofE Primary School, fire-rated sealant goes in around service penetrations where it is specified. Halls and meeting rooms at places like The Parish Church of St Bartholomew sometimes gain new services, and any compartment wall crossed needs the specified seal. Where a unit on an estate such as Aviation Trading Estate, 1 mile south of Albourne Street, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Albourne Street is about 4 miles south-west of Burgess Hill, in West Sussex. Any commercial site in Albourne Street is covered, for single jobs and planned programmes alike. We work across 373 places in West Sussex, from busy centres to rural villages. We also cover Brighton, around 8 miles from Albourne Street.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Put resealing into every M&E and fit-out package
  • Flag new cables with no seal around them
  • Record which product was used where
  • Keep general-purpose fillers away from compartment walls

Keep the product data and installation details with the building’s fire safety information. 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.

Leave it or put it right?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Around Albourne Street, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Large openings beyond what any sealant detail covers
  • Gaps in walls that were never built as compartment walls
  • Approving the work on behalf of building control

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

  • Small duct penetrations where the tested detail allows
  • Service gaps in risers
  • Pipe penetrations
  • Cable penetrations
  • Joints between fire-resisting walls and floors
  • Linear gaps at wall heads

Your questions answered

Is a smaller place like Albourne Street outside your area?

Not at all. Albourne Street is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Albourne Street 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. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Point out any areas we must not close

What the job involves on each surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.

Plastic pipes

Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
