What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Problems with the door itself rather than the gap around the frame
- Certifying a building or signing off its fire safety
- Large holes that need a different fire-stopping system
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Outdoor work around North Lochs 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.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents and landlords in North Lochs can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the job changes by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Workplaces and buildings in North Lochs
For seaside hotels, guest houses and holiday lets around North Lochs, 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. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments.
In and around North Lochs, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint. For buildings such as Parish Church, service openings in its walls need the right fire-rated sealant, as in any building.

Why deal with it now?
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. In an older home around North Lochs, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.

North Lochs questions
Do you cover smaller places like North Lochs?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
How do Scotland’s building regulations apply to fire-rated sealant in North Lochs?
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 do fire risk assessments; your assessor or building control can tell you what’s required.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
How long does fire rated sealant take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How do I get a quote for fire rated sealant in North Lochs?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Flag any open gap you spot round a pipe or cable
- Tell trades working in the building that fire seals must be put back
- Check whether a sealant can be painted before decorating over it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
