About our fire stopping in Blackhill
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you have fire-stopping items raised at inspection or handover and old intumescent sealant that has split away, we can put it right, whatever the surface. Searching for sealant specialists in Blackhill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Refurbishments in small hotels, schools and care homes around places like Blackhill can leave gaps around new services. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Surface by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
Why it’s worth doing now in Blackhill
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Renewing every failing joint on one visit is the sensible approach for a place like Blackhill. Send photos and we’ll quote for everything together.
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Your questions answered
Do you seal service penetrations in hotels around Blackhill?
Yes. We install fire-rated and intumescent sealant where it is specified. 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.
Can you take on a job at a hospital such as Balfour Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Large openings beyond what any sealant detail covers
- Fire doors, dampers or other fire safety equipment
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Small duct penetrations where the tested detail allows

Fire-rated sealing for Blackhill buildings
Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified. Blackhill has plenty of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a hotel such as Ayre Hotel, 1.1 miles east of Blackhill, penetration seals are worth checking after any refit or services upgrade. Wherever services are added at a hospital such as Balfour Hospital, 1.2 miles to the south-east of Blackhill, the compartment line has to be made good with the specified product.
Blackhill is about 1 mile west of Kirkwall, in the Orkney Islands. We send applicators to Blackhill for service penetrations. Blackhill is one of 51 places we cover in the Orkney Islands.

If your building is just outside Blackhill, we cover Kirkwall (1 mile east), Greenigoe (2 miles south), Grimbister (4 miles west), Finstown (5 miles west) and Heddle (5 miles west).
