Fire stopping across Thankerton

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why deal with it now?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Around smaller places like Thankerton, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Fire stopping for commercial buildings in Thankerton

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you have service penetrations left open after M&E works and fire sealant pulled out of the opening, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thankerton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Refurbishments in small hotels, schools and care homes around places like Thankerton can leave gaps around new services. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

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.

Common questions from Thankerton clients

Is Thankerton off your patch?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Good photographs up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Kello Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

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

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so check your contract first. Where it isn’t required, we install the specified sealant to the maker’s details.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you need to see the site first?

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

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What we are called out for in Thankerton

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

Typical triggers for a call:

  • Openings left by services added after handover
  • Improvised or mixed-product fire seals
  • Open linear gaps along the top of fire-resisting walls
  • Snag lists that include open service penetrations

For a building such as Covington Parish Church, new heating or data runs are the usual reason penetrations need sealing.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Where we can, we combine work around Thankerton with other jobs nearby. Tell us how flexible your dates are.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Brief every trade that openings they make must be sealed
  • Get seals inspected before ceilings and boxing close
  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Service penetrations in Thankerton buildings

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.

For a hospital such as Kello Hospital, 4.4 miles to the east of Thankerton, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Cost factors for service penetrations

Quotes vary with the job. Expect it to depend on:

  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • The site’s rules and procedures
  • Backing rod, priming and other preparation

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • When you need the work done
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
