About our fire stopping in Grantshouse

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we’re called in for most is fire-stopping items raised at inspection or handover and head-of-wall gaps with no fire seal. A specialist sealant contractor works differently from a general builder: on jobs in Grantshouse, preparation and product choice get the time they need.

For a building near Grantshouse, we plan fire-rated sealing so it’s finished in one visit where possible. Photos of the gaps, the services and the wall or floor type help us bring the right products.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. Where we can, we combine work around Grantshouse with other jobs nearby. Let us know if your dates have any give.

  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. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned.
  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

  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Advice

Compartments and services around Grantshouse

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Halls and meeting rooms at places like Grantshouse Church (Church Of Scotland) sometimes gain new services, and any compartment wall crossed needs the specified seal. For buildings in and around Grantshouse, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Settle who seals which penetrations at the start of a project
  • Look above ceilings when tiles are lifted for other jobs
  • Don’t let anyone top up a fire seal with the wrong product
  • Put resealing into every M&E and fit-out package

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.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

How the job changes by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Plastic pipes whose detail calls for a collar or wrap
  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on

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

What we seal

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

Questions about Grantshouse

How do the Scottish rules apply to fire-rated sealing in Grantshouse?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with 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.

Do you design the fire stopping for buildings in Grantshouse?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

What hours do you work?

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

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can you work while the building is occupied?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

What happens if it’s left?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Grantshouse, a repair visit takes planning, so it’s better to act early.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.
