When to call us in St David's
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Unsealed gaps around fire door frames
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
- Holes left by a change of layout
Around St David's, as everywhere, fire rated sealant is only as good as the preparation behind it.

Fire rated sealant for homes and businesses in St David's
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. We work on linear gaps, door frames and plasterboard & masonry, and the jobs we see most are old fire sealant that has split or come away and standard silicone or caulk in a fire-stopping gap.
Work in a place like St David's is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
We stand behind the work with a 12-month guarantee.

How to look after the new joints
To keep the joints looking good and working properly:
- Ask every contractor to reseal any fire stopping they disturb
- Take photos of fire stopping before ceilings or boxing go back
- Never patch a fire seal with standard sealant
- Don’t paint over fire sealant until it has cured
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.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
FAQs for St David's
Is St David's in your area for fire rated sealant?
Yes, St David's is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Will you come out to St David's?
Yes, St David's is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you fill the gap behind a fire door frame?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
How much does fire rated sealant cost in St David's?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like St David's may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- 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.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
How to get a quote
We quote each job on its own, so start by telling us what you need. Just send an email to info@mrmastic.co.uk with the details.
Advice
Landlord and commercial work in St David's
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Doors that aren’t fire doors in the first place
- Construction that does not provide fire resistance on its own
- Fire risk assessments, which need a qualified assessor
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Door frames
- Service penetrations
- Linear gaps
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. In a place like St David's, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
What you get with us
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet
- Old sealant always removed completely
- Experience in homes, commercial sites and hotels

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
