Fire stopping in Dalton

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

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Fire stopping for commercial buildings in Dalton

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. If you have head-of-wall gaps with no fire seal and fire-stopping items raised at inspection or handover, we can help, whatever the surface. One point of contact handles commercial sealant work in Dalton from the first photos to the final walk-round, whether it’s one building or several.

Refurbishments in small hotels, schools and care homes around places like Dalton 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.

Work we carry out in South Lanarkshire comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we will arrange a return visit.

Common problems we fix in Dalton

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

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

  • Fire-stopping items raised at inspection or handover
  • Unsealed penetrations discovered above suspended ceilings
  • Head-of-wall gaps with no fire seal
  • Old intumescent sealant that has split away

Theatres, wards and plant rooms at sites like Kirklands Hospital (to the east of Dalton) all have compartment walls crossed by services.

Before you book anyone

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Different surfaces, different methods

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor
  • Large openings beyond what any sealant detail covers

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Fire-rated sealing for Dalton buildings

The 2 miles around Dalton include three care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. 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. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

On estates like Priestfield Industrial Estate, 2 miles to the south-east of Dalton, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. In a school such as High Blantyre Primary, fire-rated sealant goes in around service penetrations where it is specified.

Dalton is about 1 mile north-west of Blantyre, in South Lanarkshire. Any commercial site in Dalton is covered, for single jobs and planned programmes alike. Across South Lanarkshire, 134 places are covered, Dalton among them. Our Glasgow page has more on work in that area, about 7 miles away.

If you need fire stopping in G72, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Common questions from Dalton clients

Is Dalton too far out for you?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Kirklands Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.

Can you seal any opening with fire-rated sealant?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Travel to smaller Scottish places like Dalton is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
