Fire stopping for Lacasaidh sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How we handle fire stopping in Lacasaidh
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 01277 525 020 or email the details over with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are fire seals cut back for extra cables and never reinstated and fire-rated sealant that has cracked or shrunk back. Most enquiries from Lacasaidh start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Lacasaidh, 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: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Arrange inspection before areas are covered up
- Don’t let anyone top up a fire seal with the wrong product
- Treat an open penetration as a priority repair
- Check with the data sheet before painting over fire sealant
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
How a job runs
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Lacasaidh, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Make sure the joints can be reached
- Confirm the product named in the specification
- Let building users know which areas are affected

Advice
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
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.
Compartments and services around Lacasaidh
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, and products should be tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail. Being on an island, Lacasaidh means planning around ferry times as well as the weather. With the specification and photographs of the openings, the right fire-rated products travel with us.
For buildings in and around Lacasaidh, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Common questions from Lacasaidh clients
Can you take on a job in Lacasaidh, on the island?
Yes. We work across every Scottish council area, and that includes island locations such as Lacasaidh. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
Can you produce the fire-stopping design for a job in Lacasaidh?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.
How much does the work cost?
Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or email drawings and photos with a description of the work.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What we’re called out for in Lacasaidh
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Things that typically lead to an enquiry:
- Unsealed openings around new pipes and cables
- Fire sealant pulled out of the opening
- Seals that don’t match their tested detail
- Non-fire-rated filler around services
For a building such as Kinloch Church, new heating or data runs are the usual reason penetrations need sealing.
