Fire stopping across Crosshill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

About our fire stopping in Crosshill

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Crosshill. We work on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and what we’re called in for most is non-fire-rated filler around services and fire-rated sealant that has cracked or shrunk back. Whoever orders the work in Crosshill, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Travel to smaller places like Crosshill is planned so every penetration is sealed on one trip. Send the specification and photos of the openings, with sizes if you have them.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Crosshill

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run 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.

If one of these sounds familiar, it’s time for a closer look:

  • Unsealed openings around new pipes and cables
  • Open linear gaps along the top of fire-resisting walls
  • Improvised or mixed-product fire seals
  • Fire-rated sealant that has cracked or shrunk back

For a building at a site such as Crosshill Business Centre, less than half a mile north of Crosshill, a check of penetration seals after each fit-out is good practice.

What your quote should include

  • Health and safety accreditation such as CHAS
  • How the existing material will be dealt with
  • Their approach to joint depth and backing
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Common questions from Crosshill clients

Can work in a care setting near Crosshill go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is Crosshill off your patch?

No. Small places get the same service as large ones. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you design or specify fire stopping?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Can one quote cover more than one building?

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

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

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. The rating applies to the product as tested.

Where services cross fire walls in Crosshill

Crosshill has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.

Shop fits in centres such as Cowdenbeath Retail Park (to the south of Crosshill) can bring new services through fire-resisting walls between units, which then need the specified seal. For a school such as Lochgelly High School, penetration sealing fits best at the end of the summer works.

Crosshill is about 6 miles west of Kirkcaldy, in Fife. We send applicators to Crosshill for service penetrations, handled exactly as we handle every other area. Crosshill is one of 132 places in Fife on our list for service penetrations. Edinburgh is covered too, some 15 miles away.

How the job changes by surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. Tell us who will meet us and how to get in at your building near Crosshill. We will confirm the plan with the fixed quote.

  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. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Let us know about inductions and permits
  • Confirm the product named in the specification
  • Tell us which areas need to stay in use

What affects the price in Crosshill

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Joint width, depth and condition
  • Whether the work must be split into stages

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

We can often quote from photographs and a few details. Please tell us:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. For buildings near Crosshill, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why appoint us

  • A fixed quote before work starts
  • CHAS accredited contractor
  • Failed material removed, not covered up
  • Sealing commercial buildings since 2005

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Certain joints really need a specialist: 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.
