Questions from Charleston
Do you work for hotels and guest houses in Charleston?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Invergowrie station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself, and we’ll mention anything we notice about the door.
How much does fire rated sealant cost in Charleston?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Do you carry out fire risk assessments?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you cover Charleston?
Yes, we do. Our applicators work in Charleston.
Fire rated sealant in Charleston, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate. We work on pipe & cable gaps, door frames and flats & HMOs, and the jobs we see most are door frames with gaps between frame and wall and gaps where walls meet ceilings or slabs.
Hotels, serviced apartments and student accommodation in Scotland’s cities need their bathrooms kept in order between guests, so jobs in Charleston can be programmed room by room, with out-of-hours working possible to arrange.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In a city area like Charleston, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Let us know about stairs, lifts or work at height

What sealant work can’t fix

- Assessing a building’s fire safety
- Issuing a fire rating or certificate for a building
- Large holes that need a different fire-stopping system
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Plan fire stopping into any work that goes through walls or floors
- File the fire-stopping record where your assessor can find it
- Never patch a fire seal with standard sealant
- Take photos of fire stopping before ceilings or boxing go back
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
What we are called out for in Charleston
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
These are the problems we are asked about most:
- Open joints along the top of partitions
- Ordinary sealant used where a fire-rated product was needed
- Damaged fire sealant left by other trades
- Gaps flagged on a fire risk assessment
If you let a flat or house near Invergowrie station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What happens if it’s left?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that does not depend on other work. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why us?
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet
- Old sealant always removed completely
- Approved under the ARBOMaster scheme

Quotes for fire rated sealant in Charleston
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- Access and height
- Any mould that needs treating
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
To make quoting easier, please include:
- Roughly how big the job is
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Pictures of the joints, sent by email
Asking for a quote is easy: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Commercial buildings in Charleston
For seaside hotels, guest houses and holiday lets around Charleston, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.
Schools such as Menzieshill High School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Lochee Baptist Church, gaps around pipes and cables are worth checking after any building work there.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
