Why act early in Bigton
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. 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.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Fire stopping in Bigton
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Bigton. Most enquiries involve non-fire-rated filler around services and openings found when ceilings come down for a refit, on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers. A specialist sealant contractor works differently from a general builder: on jobs in Bigton, preparation and product choice get the time they need.
Hotels and care homes around smaller places like Bigton often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Fire stopping around Bigton: what changes locally
For an island location such as Bigton, work is planned around ferry crossings and the weather. We need the specification and a count of penetrations before we sail. 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.
Around Bigton, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product. Halls and meeting rooms at places like St Ninian's Church And Gatepiers sometimes gain new services, and any compartment wall crossed needs the specified seal.
Bigton is in the Shetland Islands. We cover commercial sites throughout Bigton, whether it’s a single job or part of a planned programme. Bigton is one of 63 places we cover in the Shetland Islands.
Commercial sites across ZE2 are covered for service penetrations. Just outside Bigton, we also work in Levenwick (2 miles east), Hoswick (3 miles north-east), South Scousburgh (3 miles south), Sandwick (3 miles north-east) and Boddam (4 miles south). A short drive away, we cover Lerwick (13 miles north-east), Sound (13 miles north-east) and Scalloway (11 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call 01277 525 020 or email us.

Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Travel to smaller Scottish places like Bigton is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Let us know about inductions and permits
- Have the specification and drawings to hand
- Move anything stored against the joints
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

How the job changes by surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Working within restricted access windows
- Distance, for remote addresses
- How much existing material needs removing
- Any access equipment needed
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- Any specification or named product
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.
Common questions from Bigton clients
Can you produce the fire-stopping design for a job in Bigton?
No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
Will you travel to Bigton on the island?
Yes. Islands are part of our area, Bigton included. We group island work where we can and plan around the crossings.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Keep product data and details in the fire safety file
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Flag new cables with no seal around them
- Don’t let anyone top up a fire seal with the wrong product
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
