About our fire rated sealant in Walston
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. If you have gaps flagged on a fire risk assessment and standard silicone or caulk in a fire-stopping gap, we can help, whatever the surface.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
Whatever the size of the job, you get the same one-year guarantee.

Walston questions
Is Walston within the area you cover?
Yes. Walston 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.
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. 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.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, large or small.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used for your files.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Do you certify the fire stopping?
We don’t 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.
Fire rated sealant in Walston: local notes
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we do not certify buildings or carry out fire risk assessments.
For buildings such as Walston Parish Church, service openings in its walls need the right fire-rated sealant, as in any building. In and around Walston, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
What affects the quote in Walston
There’s no set price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The size of the job

- The product the joint needs

Why it’s worth doing now in Walston
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- Old sealant always removed completely
- A 12-month guarantee on all work

How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- 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.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
How to get a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Related advice
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask every contractor to reseal any fire stopping they disturb
- Don’t paint over fire sealant until it has cured
- Take photos of fire stopping before ceilings or boxing go back
- Store the list of sealed gaps with your building paperwork
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
