Do you need fire rated sealant in Castledykes?
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common.
The most common problems we see are:
- Cracked or shrunken fire-rated sealant
- Open joints along the top of partitions
- Holes left by a change of layout
- Fire stopping disturbed by later work
If you look after a building such as Dumfries Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.

Castledykes questions
Is Castledykes within the area you cover?
Yes. Castledykes is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you take on hotel work around Castledykes?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are. We will confirm how long when we quote.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How to look after the new joints
To keep the joints looking good and working properly:
- Include hidden areas like risers in routine checks
- Report cracked or damaged seals as soon as you notice them
- Don’t paint over fire sealant until it has cured
- Allow for resealing whenever new services are run
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
Honest limits
It helps to know what we cannot do:
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone is not the tested solution
- A wall that isn’t a fire-resisting element to begin with
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
What we seal
- Flats & HMOs
- Door frames
- Service penetrations
- Linear gaps
- Pipe & cable gaps
- Plasterboard & masonry
Surface by surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins to keep disruption down.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
What fire rated sealant looks like in Castledykes
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments. There are hotels and other places to stay in and around Castledykes. Hotel work can be planned room by room, with out-of-hours working where needed.
Rented homes near Dumfries station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Troqueer Parish Church are part of the picture too: gaps around pipes and cables are worth checking after any building work 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.
