Fire stopping for businesses in Thornhill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Your questions answered
Can you seal around new services in a hotel near Thornhill?
Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is a smaller place like Thornhill outside your area?
Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What do you charge?
There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Fire stopping in Thornhill, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve fire sealant pulled out of the opening and non-fire-rated filler around services, on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Thornhill, preparation and product choice get the time they need.
Around smaller places such as Thornhill, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Different surfaces, different methods
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, 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.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
If you are not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations

What sets the cost
Before we quote, we look at:
- Removal of failed or old sealant
- Travel to remote or island sites
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
- Anything awkward about access or site hours
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs near Thornhill are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.

Preparing the site
- Point out any areas we must not close
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work

Penetration seals near Thornhill
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, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail. Several hotels sit less than 2 miles from Thornhill. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
At a healthcare site like Thornhill Hospital (under half a mile south of Thornhill), new services through compartment walls are a constant, and each needs the specified seal. In a school such as Wallace Hall Academy, fire-rated sealant goes in around service penetrations where it is specified. Hotels such as Buccleuch and Queensberry Arms Hotel (under half a mile south-east of Thornhill) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Thornhill is about 13 miles north-west of Dumfries, in Dumfries and Galloway.
