Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why act early in Garrabost
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. 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.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

About our fire stopping in Garrabost
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve openings found when ceilings come down for a refit and snag lists that include open service penetrations, on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations. Looking for mastic applicators who cover Garrabost? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Refurbishments in small hotels, schools and care homes around places like Garrabost 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.
Whoever the client is, the cover is the same: 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.

Common problems we fix in Garrabost
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Fire stopping installed outside its tested range
- Fire-rated sealant that has cracked or shrunk back
- Snag lists that include open service penetrations
- Seals disturbed by maintenance and left open
In a building such as Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
- Their public liability cover
- The named product and why it was chosen

Fire stopping around Garrabost: points for this area
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, and products should be tested for their end use. We install what’s specified, to the product’s tested detail. Being on an island, Garrabost means planning around ferry times as well as the weather. We need the specification and a count of penetrations before we sail.
Hospital estates such as Western Isles Hospital (to the west of Garrabost) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Garrabost is in Na h-Eileanan Siar. We cover commercial sites throughout Garrabost, for single jobs and planned programmes alike. Across Na h-Eileanan Siar, 87 places are covered, Garrabost among them.
We cover the HS2 postcode districts for service penetrations. For a building on Graham Avenue and Claypark Road or nearby, we can quote for service penetrations. Sites close to Garrabost are covered too, including Pabail Uarach (1 mile south-east), Sulaisiadar (1 mile north-east), Lower Bayble (1 mile south), Knock (2 miles south-west) and Na h-Eileanan an Iar (2 miles south-west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Common questions from Garrabost clients
How do Scotland’s building standards affect fire-rated sealant in Garrabost?
The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.
Is hospital work, at somewhere like Western Isles Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
How long do sealant joints 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.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Travel to smaller Scottish places like Garrabost is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Where we work in Garrabost
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The product specified
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
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’ll have a fixed figure to work with.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- When you need the work done
- The postcode of the building
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Check with the data sheet before painting over fire sealant
- Check risers and ceiling voids after each round of works
- Get seals inspected before ceilings and boxing close
- Keep product data and details in the fire safety file
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
