Fire stopping in Lybster
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Lybster, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email the details over.
Advice
Fire stopping for commercial buildings in Lybster
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with unsealed joints where partitions meet the slab and fire stopping installed outside its tested range, we can put it right. A single leaking joint is often how a building in Lybster first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Travel to smaller places like Lybster is planned so every penetration is sealed on one trip. Send the specification and photographs of the openings, with sizes if you have them.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Other services in Lybster
Fire stopping around Lybster: points for this area
A 2-mile radius around Lybster takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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. We install fire-rated sealant to that tested detail where it is specified.
Halls and meeting rooms at places like St Mary's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
Lybster is about 22 miles south-east of Thurso, in Highland. Commercial clients in Lybster can call on us for service penetrations. 256 places across Highland fall within our area, including Lybster.
Work on service penetrations is covered throughout KW3, for business premises of every kind. If your site is on Main Street, Jeffrey Street and Russell Street or close by, we can quote for service penetrations. If your building is just outside Lybster, we cover Dunbeath (6 miles south-west), Balnabruich (7 miles south-west), Thrumster (8 miles north-east), Whiterow (11 miles north-east) and Haster (11 miles north-east). For island and remote sites, travel and materials need planning ahead, so include the location in your enquiry.
What’s near Lybster
A little further out are Swiney Castle (1.4 miles south-west) and Waterlines (less than half a mile south). Open spaces near Lybster include Ben-a-chielt.
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
When to call us in Lybster
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, so it has to come out.
It’s worth sending us details if you spot any of the following:
- Expanding foam used as fire stopping
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
- Damaged fire seals in risers and voids
For a hotel such as The Commercial Hotel (less than half a mile north of Lybster), penetration seals are worth checking after any refit or services upgrade.

Common questions from Lybster clients
What do Scotland’s building standards say about service penetrations in Lybster?
Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.
Is Lybster too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What will the job cost?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Report damaged or disturbed seals as soon as they’re spotted
- Ask which product is in place before decorating
- Keep product data and details in the fire safety file
- Ask the designer to confirm details early on refits
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
