About our fire stopping in Breach Barns

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on cable penetrations, joints between fire-resisting walls and floors and service gaps in risers, and what we’re called in for most is snag lists that include open service penetrations and fire seals cut back for extra cables and never reinstated. Most enquiries from Breach Barns start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A job near Breach Barns is normally planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why act early in Breach Barns

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Breach Barns. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: 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 you get with us

  • Work to your specification and the manufacturer’s guidance
  • A Constructionline member, so easy to vet
  • Joints cleaned back to sound surfaces
  • CSCS-carded applicators

Read our cost guide and our accreditations.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Whether the work must be split into stages
  • The total length or number of joints
  • Which sealant the job calls for
  • The site’s rules and procedures

Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Any dates the work must fit around

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

Breach Barns: questions and answers

What happens to BS 476 references for fire stopping in Breach Barns?

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.

Is Breach Barns too far out for you?

No. Places such as Breach Barns are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can staff carry on working while you’re here?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

How many days will you need on site?

That varies with the scale of the job, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Looking after the joints

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

  • Check risers and ceiling voids after each round of works
  • Brief every trade that openings they make must be sealed
  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Rural sites near Breach Barns may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Approving the work on behalf of building control
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Surfaces we seal

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

What we’re called out for in Breach Barns

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Look out for the following:

  • Penetration schedules that need working through
  • Expanding foam used as fire stopping
  • Openings found when ceilings come down for a refit
  • Fire seals cut back for extra cables and never reinstated

Tenant changes at parks like Warlies Business Park, 0.8 miles to the south-east of Breach Barns, bring new data and services, and openings through fire-resisting walls need the specified seal.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?
  • Their public liability cover

Fire-rated sealing for Breach Barns buildings

In England, Approved Document B covers fire stopping of openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail. Central London is about 15 miles from Breach Barns. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Hospital estates such as St. Margaret's Hospital (3.7 miles east of Breach Barns) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Older community buildings such as Church of St Thomas that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
