Signs you need fire rated sealant in Hillswick
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
If you can see any of these, it’s time to have the joints looked at:
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
- Gaps left after a refit or conversion
- Open gaps behind door architraves
Around Hillswick, as everywhere, fire rated sealant is only as good as the preparation behind it.
Questions to ask before booking
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Whether they’re fully insured
- Which colour the sealant will be
How we handle fire rated sealant in Hillswick
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. Common call-outs are for linear gaps at the head of walls and new service routes left unsealed after building work, on service penetrations, plasterboard & masonry and pipe & cable gaps.
If you look after holiday lets, a guest house or a community building in or near Hillswick, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. The work generally takes from a few hours to a few days, depending on the number of gaps and the access. Outdoor work around Hillswick depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions

Related advice
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. Around Hillswick, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Your questions about fire rated sealant in Hillswick
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that’s how we fit it. 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.
Do you cover Hillswick for fire rated sealant?
Yes. Our work covers the whole of Scotland, and Hillswick is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Where is Mr Mastic based?
We work from Crawley. We cover Hillswick and the rest of the Shetland Islands, along with the rest of our area.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
