Compartments and services around Pirnmill
Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, 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.
Around Pirnmill, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product. Halls and meeting rooms at places like Pirnmill Church Of Scotland sometimes gain new services, and any compartment wall crossed needs the specified seal.

Fire stopping in Pirnmill
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about penetration schedules that need working through and fire seals cut back for extra cables and never reinstated, across pipe penetrations, linear gaps at wall heads and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Pirnmill, preparation and product choice get the time they need.
Travel to smaller places like Pirnmill is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.

Questions about Pirnmill
Is Pirnmill 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.
Can you produce the fire-stopping design for a job in Pirnmill?
No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
How many days will you need on site?
It depends on the scope, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Can staff carry on working while you’re here?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Check with the data sheet before painting over fire sealant
- Settle who seals which penetrations at the start of a project
- Have penetrations checked while they can still be seen
- Brief every trade that openings they make must be sealed
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
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.
Surface by surface
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening.
Other services in Pirnmill
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Pirnmill are often grouped with others in the same area. Tell us how flexible your dates are.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in
- Tell us which areas need to stay in use
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Related advice
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Writing the fire-stopping specification
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
