How the job changes by surface
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Flats and HMOs
Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.
Fire rated sealant in Sandwick
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. Common call-outs are for old fire sealant that has split or come away and gaps around pipes and cables through fire-resisting walls, across plasterboard & masonry, door frames and flats & HMOs.
Work in a place like Sandwick is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.

When to call us in Sandwick
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
The most common problems we see are:
- Open gaps behind door architraves
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
In and around Sandwick, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

How it works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Sandwick may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Fire doors that need new seals, closers or hardware
- Construction that does not provide fire resistance on its own
- Deciding what fire stopping a building needs
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
Where we work in Sandwick
- Service penetrations
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames

Looking after it afterwards
Aftercare is simple:
- Include hidden areas like risers in routine checks
- Flag any open gap you spot round a pipe or cable
- Ask which product was used before you paint
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Your questions about fire rated sealant in Sandwick
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is 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.
Can you do fire rated sealant in Sandwick?
Yes, Sandwick is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used for your files.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
What should I tell you?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Can you work in occupied buildings?
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.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.
Commercial buildings in Sandwick
If you run a hotel, guest house or holiday let in a coastal place like Sandwick, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
