What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

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

Fire stopping in Twynholm, done properly

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. Site teams most often ask us about fire-stopping items raised at inspection or handover and fire stopping installed outside its tested range, across service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. Most enquiries from Twynholm 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.

Around smaller places such as Twynholm, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Signs you need fire stopping in Twynholm

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Clients normally get in touch after noticing something like this:

  • Fire stopping installed outside its tested range
  • Fire-stopping items raised at inspection or handover
  • Non-fire-rated filler around services
  • Damaged fire seals in risers and voids

Schools such as Kirkcudbright Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Will RAMS and insurance details be available?
  • Proof of insurance
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Your questions answered

Is Twynholm too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.

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

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.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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.

How long does a typical visit take?

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

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Flag new cables with no seal around them
  • Don’t let anyone top up a fire seal with the wrong product
  • Arrange inspection before areas are covered up
  • Record which product was used where

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Twynholm before they leak.

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What the job involves on each surface

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We confirm material and size first and tell you if sealant isn’t the right product.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Twynholm, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  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. Improvised fillers and failed sealant are removed.
  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. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Warn occupants and staff about the work
  • Make sure the joints can be reached
  • Send your site hours and access windows

Compartment walls and floors in Twynholm

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.

Hotels such as The Star Hotel, under half a mile to the north-east of Twynholm, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For a hospital such as Kirkcudbright Hospital, 2.5 miles to the south-east of Twynholm, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
