About our fire rated sealant in Grimeston
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. If you have cracked or shrunken fire-rated sealant and linear gaps at the head of walls, we can put it right.
For a place like Grimeston, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.
A one-year guarantee comes as standard.

Fire rated sealant around Grimeston
If you run a hotel, guest house or holiday let in a coastal place like Grimeston, 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. Fire-rated sealant is installed to the manufacturer’s tested details, though we don’t certify buildings or do fire risk assessments.
Whether the job is in Grimeston itself or nearby, the right material for each joint matters as much as a neat finish.
Grimeston is about 9 miles west of Kirkwall, in the Orkney Islands. Every kind of property in Grimeston is covered for fire rated sealant, old or new, large or small. The work is guaranteed for a year. We cover 51 towns and villages across the Orkney Islands.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a place like Grimeston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
How to prepare
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

What else we do in Grimeston
When to call us in Grimeston
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Look out for these signs:
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
- Cracked or shrunken fire-rated sealant
- Open joints along the top of partitions
Around Grimeston, as everywhere, fire rated sealant is only as good as the preparation behind it.
Before you book anyone
- Whether they seal over old material or remove it
- What guarantee comes with the work
- How much experience the applicator has
- How the joint is cleaned and prepared
Why it’s worth doing now in Grimeston
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Your questions about fire rated sealant in Grimeston
Do you cover smaller places like Grimeston?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
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 don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Do you do fire sealant around door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can I use normal mastic around a pipe through a fire wall?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Issuing a fire rating or certificate for a building
- Walls or floors that weren’t built to resist fire
- Deciding what fire stopping a building needs
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
