About our fire rated sealant in Charleston
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have seals cut through by electricians, plumbers or data installers and ordinary sealant used where a fire-rated product was needed, we can help, whatever the surface.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a place like Charleston, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

FAQs for Charleston
Do you take on hotel work around Charleston?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you cover smaller places like Charleston?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
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.

What affects the cost of fire rated sealant
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- The amount of work
- Whether old sealant or filler has to be cut out
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is
- What’s wrong with the joints now
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
To get a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep photos of seals that will be hidden
- Tell trades working in the building that fire seals must be put back
- Include fire stopping when you schedule refits
- Get damaged fire seals looked at promptly
Any fire seal that’s 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.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What fire rated sealant looks like in Charleston
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’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 Charleston. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you look after a building such as Castlehead High School, service openings in fire-resisting walls need checking after any refurbishment.

Do you need fire rated sealant in Charleston?
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.
Keep an eye out for any of the following:
- Gaps filled with a product that is not fire-rated
- Open gaps behind door architraves
- Old fire sealant that has split or come away
- Fire stopping disturbed by later work
If you let a flat or house near Paisley Canal station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
