Fire rated sealant in Mountcastle
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 flats & HMOs, plasterboard & masonry and linear gaps, and people most often call us about damaged fire sealant left by other trades and gaps flagged on a fire risk assessment.
Scotland’s cities have offices, hotels, student flats, care homes and tenement blocks looked after by factors. For a building in Mountcastle, the job might be washroom resealing or fire-rated sealant around service openings.
Whatever the size of the job, it’s backed by our one-year guarantee in Mountcastle and across Edinburgh.

What else we do in Mountcastle
Fire rated sealant around Mountcastle
If you run a hotel, guest house or holiday let in a coastal place like Mountcastle, 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. There are hotels and other places to stay in and around Mountcastle. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Managing a site like Portobello High School? Then service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Willowbrae Parish Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Brunstane station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
Mountcastle is about 3 miles east of Edinburgh, in Edinburgh. Wherever you are in the EH15 postcode area, our applicators can take on fire rated sealant. Mountcastle is one of 175 places in Edinburgh where we work for fire rated sealant.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Tell trades working in the building that fire seals must be put back
- Plan fire stopping into any work that goes through walls or floors
- Take pictures of fire stopping before ceilings or boxing go back
- Never patch a fire seal with standard sealant
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
Common questions in Mountcastle
Do you work for hotels and guest houses in Mountcastle?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do Scottish building rules affect fire-rated sealant work in Mountcastle?
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 don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
How do I get a quote for fire rated sealant in Mountcastle?
Size, access and the old material all affect the cost. Ask us for a quote.
What fire rating will the seal have?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do you have insurance?
Yes. Full insurance covers our work.
Quotes for fire rated sealant in Mountcastle
The quote reflects the job in front of us. We look at:
- The type of sealant required
- The number and length of the joints
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What we need to know
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- The problem you’ve noticed
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
- Walls or floors that weren’t built to resist fire
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Plasterboard & masonry
- Door frames
- Pipe & cable gaps
- Service penetrations
- Linear gaps
- Flats & HMOs
Leave it or put it right?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Combining jobs into one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. Parking in city streets around Mountcastle can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
