What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Plastic pipes whose detail calls for a collar or wrap
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
Where we work in Mossbank

Fire stopping in Mossbank
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. The enquiries we see most involve unsealed openings around new pipes and cables and fire sealant pulled out of the opening, on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations. Looking for mastic applicators who cover Mossbank? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Hotels and care homes around smaller places like Mossbank often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Fire stopping around Mossbank: how the place shapes the job
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. Island jobs, Mossbank among them, are planned around the ferry and the forecast. We need the specification and a count of penetrations before we sail.
For buildings in and around Mossbank, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. Around Mossbank, fire-stopping design belongs to the designer and building control; installation to the specification is our part.
Mossbank is in the Shetland Islands. Commercial clients in Mossbank use us for work on service penetrations. 63 places across the Shetland Islands fall within our area, including Mossbank.
Work on service penetrations is covered throughout ZE2, whatever the building. Among the streets we cover are Smuggabank, Rayburn Road and Burraness, and sites on any of them can send details for a fixed quote. If your building is just outside Mossbank, we cover Firth (1 mile south-west), Scatsta (4 miles south-west), Burravoe (5 miles north-east), Ollaberry (6 miles north-west) and Vidlin (6 miles south). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call the office on 01277 525 020 or email the details over.

What the job involves on each surface
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we’ll tell you what the detail says instead.

Why act early in Mossbank
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Mossbank before they leak.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Questions about Mossbank
Will you design a fire-stopping scheme for our building in Mossbank?
No. The designer or fire engineer sets the detail and building control accepts it. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
How do Scotland’s building standards affect fire-rated sealant in Mossbank?
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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
What happens if old sealant might contain asbestos?
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.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Include service cupboards in routine inspections
- Arrange inspection before areas are covered up
- Brief every trade that openings they make must be sealed
- File the specified details where the next contractor can find them
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near Mossbank, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let us know about inductions and permits
- Agree which areas must stay open
- Send your site hours and access windows
