Fire-rated sealant in Strathy, Highland

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
About our fire rated sealant in Strathy
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. We work on door frames, pipe & cable gaps and plasterboard & masonry, and people most often call us about gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap.
If you look after holiday lets, a guest house or a community building in or near Strathy, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Big or small, you get the same 12-month guarantee in Strathy and across Highland.

Leave it or put it right?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. In an older home around Strathy, damp from a failed joint can get into timber and plaster.

FAQs for Strathy
Is Strathy within the area you cover?
Yes, Strathy is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Can ordinary silicone be used in a fire-stopping gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long does fire rated sealant take?
It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll give you a better idea when we quote.

Do you need fire rated sealant in Strathy?

Common reasons people contact us include:
- Gaps around pipes and cables through fire-resisting walls
- Holes left by a change of layout
- Cracked or shrunken fire-rated sealant
- Gaps filled with a product that is not fire-rated
For jobs in and around Strathy, choosing the right material for each joint is as important as a tidy finish.

What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a handful of gaps, and longer for a whole building. Outdoor work around Strathy depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Ask which product was used before you paint
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
- Report cracked or damaged seals as soon as you notice them
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.
When it is not the sealant
We will not take on work that won’t last, so here’s what sealant cannot put right:
