How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins to keep disruption down.
Commercial buildings in Keiss
For seaside hotels, guest houses and holiday lets around Keiss, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details, though we do not certify buildings or do fire risk assessments.
For buildings such as Church of Scotland, older buildings that have had new heating or wiring often have service gaps worth checking.

Questions from Keiss
Do you cover Keiss for fire rated sealant?
Yes, Keiss is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do Scottish building rules affect fire-rated sealant work in Keiss?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is 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.
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.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Do you work in flats, HMOs and commercial buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine. Out-of-hours work can be arranged if that suits the building.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
- Certifying a building or signing off its fire safety
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.

What affects the cost of fire rated sealant
You will get a clear quote before we start. It’s based on:
- The amount of work
- The type of sealant required
- How many areas need sealing
- When we can work, for business premises
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. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The problem you’ve noticed
- The address or postcode of the job
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Outdoor work around Keiss depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep the record of products and locations with your fire safety documents
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
- Make resealing part of every contractor’s brief
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What we’re called out for in Keiss
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
Look out for these signs:
- Unsealed gaps where pipes and cables go through a wall
- Unsealed gaps around fire door frames
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
In and around Keiss, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Who turns up on the day
- Are they insured?
- What product goes in the joint
