Building owners, agents and FMs in Backburn

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Fire stopping in Backburn, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. Site teams most often ask us about fire-rated sealant that has cracked or shrunk back and snag lists that include open service penetrations, on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Backburn, preparation and product choice get the time they need.

Refurbishments in small hotels, schools and care homes around places like Backburn can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Service penetrations in Backburn buildings

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail.

Older community buildings such as St Andrew's Parish Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Backburn is about 16 miles north-west of Inverurie, in Aberdeenshire. Businesses, contractors and managing agents in Backburn can call on us for service penetrations. Backburn is one of 179 places we cover in Aberdeenshire for service penetrations. We also cover Aberdeen, around 30 miles from Backburn.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Ask the designer to confirm details early on refits
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Have penetrations checked while they can still be seen

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

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.

Site staff or a sealant specialist?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

How the job changes by surface

Metal pipes

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

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

Common questions from Backburn clients

Is Backburn off your patch?

No. Places such as Backburn are covered as much as the big towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Jubilee Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

What does an EI 60 rating mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Backburn, we aim for one trip, which is why we ask for photographs and a full list first. 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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Send any specification or drawings in advance
  • Point out any areas we must not close
  • Arrange parking or a loading space

Advice

Common problems we fix in Backburn

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

Site and facilities staff are often the first to spot these:

  • Service penetrations left open after M&E works
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire seals cut back for extra cables and never reinstated
  • Fire sealant pulled out of the opening

At a healthcare site like Jubilee Hospital, which lies north of Backburn, new services through compartment walls are a constant, and each needs the specified seal.

Questions to ask before you book

  • Proof of insurance
  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • Whether old or failed sealant will be cut out, not overlaid
