About our fire stopping in Tolastadh bho Thuath

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Tolastadh bho Thuath. If you have fire-stopping items raised at inspection or handover and builders’ foam or ordinary silicone in compartment walls, we can put it right, on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads alike. Most enquiries from Tolastadh bho Thuath start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Travel to smaller places like Tolastadh bho Thuath is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Surface by surface

Metal pipes

Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Tolastadh bho Thuath: questions and answers

Do you decide the fire-stopping details for buildings in Tolastadh bho Thuath?

No. The designer or fire engineer sets the detail and building control accepts it. We install what’s specified, to the product’s tested detail.

Which Scottish guidance covers penetration seals in Tolastadh bho Thuath?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building near Tolastadh bho Thuath, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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.

What we need from you

  • Point out parking and an unloading spot
  • Make sure the joints can be reached
  • Point out any areas we must not close

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or use the quote form.

Common problems we fix in Tolastadh bho Thuath

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. Over a few years of fit-outs, a wall can collect a lot of these.

Look out for the following:

  • Fire seals cut back for extra cables and never reinstated
  • Fire-stopping items raised at inspection or handover
  • Unsealed joints where partitions meet the slab
  • Service penetrations left open after M&E works

Wherever the building is near Tolastadh bho Thuath, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with

How to choose a sealant contractor

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Walls or floors that aren’t fire-resisting to begin with
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire doors, dampers or other fire safety equipment

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

Joints and surfaces we work on

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

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Don’t let anyone top up a fire seal with the wrong product
  • Check with the data sheet before painting over fire sealant
  • Look above ceilings when tiles are lifted for other jobs
  • Have penetrations checked while they can still be seen

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
