About our fire stopping in Throsk
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Throsk and nearby. Most enquiries involve service penetrations left open after M&E works and snag lists that include open service penetrations, on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations. Looking for mastic applicators who cover Throsk? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For a building near Throsk, we plan fire-rated sealing so it’s finished in one visit where possible. Photos of the gaps, the services and the wall or floor type help us bring the right products.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Common problems we fix in Throsk
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
These are often picked up first by site or facilities staff:
- Openings left by services added after handover
- Seals that don’t match their tested detail
- Head-of-wall gaps with no fire seal
- Old intumescent sealant that has split away
For a hospital such as William Simpson Asylum, which lies south of Throsk, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- The terms of the workmanship guarantee
- The named product and why it was chosen
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Throsk. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Questions we are asked in Throsk
Is Throsk too far out for you?
Not at all. Throsk is within our area. We work across every Scottish council area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Bandeath Industrial Estate, near Throsk?
Yes. Our area takes in Throsk and its surroundings, with estates and business parks such as Bandeath Industrial Estate included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How much does the work cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Service penetrations in Throsk buildings
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.
Schools such as Alloa Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On estates like Bandeath Industrial Estate (0.6 miles north of Throsk), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
Throsk is about 3 miles south-west of Alloa, in Stirling. Any commercial site in Throsk is covered, whether it’s a single job or part of a planned programme. Throsk is one of 52 places in Stirling on our list for service penetrations. For work in that direction, see our Glasgow page, about 24 miles away.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For work around Throsk, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Make sure the joints can be reached
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep product data and details in the fire safety file
- Don’t let anyone top up a fire seal with the wrong product
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match.
