Different surfaces, different methods
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Fire rated sealant in Dalkeith, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. Typical jobs include gaps where walls meet ceilings or slabs and ordinary sealant used where a fire-rated product was needed, on plasterboard & masonry, door frames and service penetrations.
In a Scottish town like Dalkeith, commercial work can mean offices, shops, schools, hotels or care homes, all with washroom, kitchen and fire-rated joints to look after.
A 12-month guarantee comes as standard.

What fire rated sealant looks like in Dalkeith
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, though we do not certify buildings or do fire risk assessments.
If you look after a church, hall or community building such as East Kirk, service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Eskbank station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. A visit in Dalkeith needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

For landlords and businesses

Leave it or put it right?
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. If you live in a flat in Dalkeith, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Signs you need fire rated sealant in Dalkeith
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Signs it’s time to call us include:
- Old fire sealant that has split or come away
- Gaps filled with a product that isn’t fire-rated
- Gaps flagged on a fire risk assessment
- Holes left by a change of layout
For site and facilities teams at buildings such as Dalkeith High School, service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Dalkeith
Do you work for landlords with property near Eskbank station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is Dalkeith in your area for fire rated sealant?
Yes, Dalkeith is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you certify the fire stopping?
Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
How long does the job take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we’ll say how long yours will take.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep pictures of seals that will be hidden
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
- Do not fill fire-stopping gaps with ordinary foam or silicone
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
