Fire stopping in Cross

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Cost factors for service penetrations

Before we quote, we look at:

  • Phasing around occupants
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The site address and postcode
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • The product your specification calls for

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email the details over.

Fire stopping in Cross

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call the office on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you’re dealing with openings left by services added after handover and head-of-wall gaps with no fire seal, we can put it right, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Cross is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a building near Cross, 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we will come back to it.

Cross: questions and answers

Do you design the fire stopping for buildings in Cross?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

How do Scotland’s building standards affect fire-rated sealant in Cross?

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.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you take on multi-site work?

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

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Where we can, we combine work around Cross with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use
  • Confirm the product named in the specification

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Don’t let anyone top up a fire seal with the wrong product
  • Flag new cables with no seal around them
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check with the data sheet before painting over fire sealant

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

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Penetration seals near Cross

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 proprietary products, intumescent ones included, tested for their end use. We install fire-rated sealant to that tested detail where it is specified. Island jobs, Cross among them, are planned around the ferry and the forecast. With the specification and photos of the openings, the right fire-rated products travel with us.

Halls and meeting rooms at places like Church of Scotland sometimes gain new services, and any compartment wall crossed needs the specified seal.

Signs you need fire stopping in Cross

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

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

  • Fire stopping installed outside its tested range
  • Old intumescent sealant that has split away
  • Penetration schedules that need working through
  • Openings left by services added after handover

Around Cross, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Health and safety accreditation such as CHAS
