Fire stopping for Glenlochar sites

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

Surface by surface

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.

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 and we confirm each before sealing.

Fire stopping for commercial buildings in Glenlochar

A fire-rated sealant is only one part of a tested system: 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 small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and what we’re called in for most is non-fire-rated filler around services and improvised or mixed-product fire seals. Most enquiries from Glenlochar start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

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

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.

Do you need fire stopping in Glenlochar?

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.

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

  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed joints where partitions meet the slab
  • Fire-rated sealant that has cracked or shrunk back
  • Service penetrations left open after M&E works

For a hospital such as Castle Douglas Hospital, 2.7 miles to the south-east of Glenlochar, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

  • How they handle RAMS and site documents

Questions about Glenlochar

Is a hospital such as Castle Douglas Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

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

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Why it’s worth doing now in Glenlochar

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. For buildings near Glenlochar, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • 12 months’ guarantee on every job
  • Health and safety: CHAS accredited
  • A Constructionline member, so easy to vet
  • Public liability insurance in place

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Where we can, we combine work around Glenlochar with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in

Quotes

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Fire risk assessments, a job for a competent assessor
  • Issuing fire ratings or certificates for seals
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Fire stopping in Glenlochar: the local picture

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.

Holiday works at schools like Castle Douglas High School often leave service openings to seal before pupils return. For a hotel such as Culgruff House Hotel, 1.5 miles to the north of Glenlochar, penetration seals are worth checking after any refit or services upgrade.
