Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Leave fire sealant to cure fully before covering it
  • Don’t let anyone top up a fire seal with the wrong product
  • Report damaged or disturbed seals as soon as they’re spotted
  • Brief every trade that openings they make must be sealed

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Approving the work on behalf of building control
  • Large openings beyond what any sealant detail covers
  • Reviewing a building’s overall fire safety

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For work around Barr, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We start with your penetration schedule, drawings or specification.
  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. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Let building users know which areas are affected

Advice

Your questions answered

Is a smaller place like Barr outside your area?

Not at all. Barr is within our area. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Girvan Community Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

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.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Is it fine to apply new sealant on top of old?

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

Do you design or specify fire stopping?

No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How the job changes by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.

When to call us in Barr

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.

These are often picked up first by site or facilities staff:

  • Unsealed joints where partitions meet the slab
  • Fire sealant pulled out of the opening
  • Damaged fire seals in risers and voids
  • Fire stopping installed outside its tested range

In a building such as Old Parish Church And Churchyard, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What your quote should include

  • How long is the guarantee, and what does it include?
  • How they handle RAMS and site documents
  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

What affects the price in Barr

Each job is priced on its own details. The main factors are:

  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Working within restricted access windows
  • Whether old sealant has to be cut out first

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email the details over.
