Compartments and services around Thurso
Thurso has plenty of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.
Hotels such as Station Hotel (less than half a mile south-east of Thurso) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Theatres, wards and plant rooms at sites like Dunbar Hospital, 0.8 miles south-west of Thurso, all have compartment walls crossed by services.

Fire stopping in Thurso, done properly
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on service gaps in risers, linear gaps at wall heads and pipe penetrations, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and hidden openings found during inspections. Searching for sealant specialists in Thurso? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
After refits and M&E works in buildings around Thurso, gaps around new services are a common finding. If fire-rated sealant is the named product, it is installed as tested; if the detail needs a different item, we’ll point that out.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Water through a failed joint in a building in Thurso can spoil ceilings, floors and stock. Putting it right early limits the damage.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Common questions from Thurso clients
What do Scotland’s building standards say about service penetrations in Thurso?
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.
Can you seal around new services in a hotel near Thurso?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How much does the work cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you need fire stopping in Thurso?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
What tends to prompt an enquiry:
- Seals disturbed by maintenance and left open
- Non-fire-rated filler around services
- Openings found when ceilings come down for a refit
- Fire-rated sealant that has cracked or shrunk back
In a school such as Thurso High School, fire-rated sealant goes in around service penetrations where it is specified.
What to look for in a quote
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
- Their plan for phasing and protecting the area
On site: what to expect
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. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in Thurso are planned with two things in mind: the forecast for external joints and the building’s hours for internal ones. Photos or drawings let us give a fixed quote and a realistic plan.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Tell us which areas need to stay in use
- Confirm the product named in the specification
- Arrange parking or a loading space

Advice
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Brief every trade that openings they make must be sealed
- Check risers and ceiling voids after each round of works
- Flag new cables with no seal around them
- Record which product was used where
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We confirm material and size first and tell you if sealant isn’t the right product.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
