General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

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.

Fire stopping in Wester Pencaitland, done properly

No fire sealant works on its own: 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. We work on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations, and what we’re called in for most is old intumescent sealant that has split away and snag lists that include open service penetrations. For commercial sealant work in Wester Pencaitland, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In smaller Scottish places like Wester Pencaitland, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Tell us who will meet us and how to get in at your building near Wester Pencaitland. That goes into the plan alongside the quote.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

Advice

FAQs: Wester Pencaitland

Do you take on work at healthcare sites like Roodlands General Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Wester Pencaitland outside your area?

No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Which standards are fire seals tested to?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.

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

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

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Do you have third-party installer accreditation for fire stopping?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What the job involves on each surface

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.

Penetration seals near Wester Pencaitland

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, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified.

Large healthcare estates like Roodlands General Hospital, 5.1 miles north-east of Wester Pencaitland, change their services often, so penetration seals are worth checking after M&E work.

What we are called out for in Wester Pencaitland

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

It’s worth sending us details if you spot any of the following:

  • Snag lists that include open service penetrations
  • Service penetrations left open after M&E works
  • Unsealed penetrations discovered above suspended ceilings
  • Fire-rated sealant that has cracked or shrunk back

Where a unit on an estate such as Macmerry Industrial Estate, which lies north of Wester Pencaitland, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • How long is the guarantee, and what does it include?
  • Which product they’ll use, and why it suits the joint

Choosing a commercial sealant contractor

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Approving the work on behalf of building control
  • Reviewing a building’s overall fire safety
  • Writing the fire-stopping specification

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Joints and surfaces we work on

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