Fire rated sealant for homes and businesses in Gelston
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, gap by gap. Common call-outs are for gaps flagged on a fire risk assessment and gaps where walls meet ceilings or slabs, on door frames, pipe & cable gaps and flats & HMOs.
If you look after holiday lets, a guest house or a community building in or near Gelston, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
You get a 12-month guarantee, the same in Gelston as everywhere else we work.

What sealant work can’t fix
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Fire risk assessments, which need a qualified assessor
- Doors that are not fire doors in the first place
- Big openings where sealant alone isn’t the tested solution
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on
- Flats & HMOs
- Plasterboard & masonry
- Pipe & cable gaps
- Linear gaps
- Door frames
- Service penetrations
What we do, step by step
The work is kept neat and contained to the joints we’re treating. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. Outside jobs in Gelston need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.
Gelston: your questions answered
Is Gelston within the area you cover?
Yes, Gelston is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do Scottish building rules affect fire-rated sealant work in Gelston?
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 do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why it’s worth doing now in Gelston
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Gelston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why Gelston clients choose us
- Tidy, careful work
- We never seal over old sealant
- Experience in homes, commercial sites and hotels
- Sanitary silicone with an anti-fungal additive in wet areas

Keeping the joints in good condition
Aftercare is simple:
- Check whether a sealant can be painted before decorating over it
- Look in service cupboards and ceiling voids from time to time
- Photograph sealed gaps before they’re covered up
- Report cracked or damaged seals as soon as you notice them
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.
