What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a place like Sound, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Mention any tricky access
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

Advice
Fire rated sealant for homes and businesses in Sound
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you have door frames with gaps between frame and wall and gaps left after a refit or conversion, we can help, whatever the surface.
If you look after holiday lets, a guest house or a community building in or near Sound, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
There’s a 12-month guarantee on every job, whatever its size.

When it is not the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
- A wall that is not a fire-resisting element to begin with
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk.

Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Sound questions
Is Sound within the area you cover?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Can new sealant go over the old?
No, it will not 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.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.
How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- How many areas need sealing
- Mould in or behind the old joints
- Working hours on commercial sites
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
To get a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.

Fire rated sealant in Sound: local notes
If you run a hotel, guest house or holiday let in a coastal place like Sound, 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. There are hotels and other places to stay in and around Sound. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Managing a site like Anderson High School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Around Sound, as everywhere, fire rated sealant is only as good as the preparation behind it.
