- Door frames with gaps between frame and wall
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Keep pictures of seals that will be hidden
- Allow for resealing whenever new services are run
- Flag any open gap you spot round a pipe or cable
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
How we handle fire rated sealant in Heriot
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you’re dealing with joints picked up in a fire-stopping survey 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 Heriot, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Our work is backed for twelve months.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Workplaces and buildings in Heriot
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 jobs in and around Heriot, choosing the right material for each joint is as important as a tidy finish.

What affects the quote in Heriot

When to call us in Heriot
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.
The problems people normally mention when they call include:
- Damaged fire sealant left by other trades
- Linear gaps at the head of walls
- Gaps around pipes and cables through fire-resisting walls
- Standard silicone or caulk in a fire-stopping gap
Around Heriot, as everywhere, fire rated sealant is only as good as the preparation behind it.

Questions from Heriot
Is Heriot in your area for fire rated sealant?
Yes. Our work covers the whole of Scotland, and Heriot is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
Do Scottish building rules affect fire-rated sealant work in Heriot?
Building work in Scotland comes under the Building (Scotland) Regulations and their 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 don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
What does intumescent mean?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you carry out fire risk assessments?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Where do you work from?
Mr Mastic is based in Crawley. We cover Heriot and the rest of the Scottish Borders.
Why deal with it now?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a place like Heriot, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. Outside jobs in Heriot need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
