Fire stopping in Upper Coll, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have fire seals cut back for extra cables and never reinstated and snag lists that include open service penetrations, we can put it right. Most enquiries from Upper Coll start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Travel to smaller places like Upper Coll is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.
A 12-month guarantee applies to all our work in Na h-Eileanan Siar. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we will come back to it.

Common problems we fix in Upper Coll
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.
Most enquiries start with something like this:
- Open linear gaps along the top of fire-resisting walls
- Non-fire-rated filler around services
- Snag lists that include open service penetrations
- Seals that don’t match their tested detail
Wherever services are added at a hospital such as Western Isles Hospital, 3 miles south-west of Upper Coll, the compartment line has to be made good with the specified product.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
- Who will actually carry out the work

Compartment walls and floors in Upper Coll
Being on an island, Upper Coll means planning around ferry times as well as the weather. We need the specification and a count of penetrations before we sail. 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, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.
Around Upper Coll, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Common questions from Upper Coll clients
How do Scotland’s building standards affect fire-rated sealant in Upper Coll?
Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.
Can you take on a job in Upper Coll, on the island?
Yes. Islands are part of our area, Upper Coll included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
What do you charge?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. Around smaller places like Upper Coll, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Surface by surface
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
