When to call us in Edgehead
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
The most common problems we see are:
- Gaps flagged on a fire risk assessment
- Open gaps behind door architraves
- Holes left by a change of layout
- Open holes round services passing through fire walls
Schools such as Newbattle Community High School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Fire rated sealant for homes and businesses in Edgehead
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with standard silicone or caulk in a fire-stopping gap and door frames with gaps between frame and wall, we can put it right.
If you look after holiday lets, a guest house or a community building in or near Edgehead, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a place like Edgehead, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, 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.
The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Edgehead: your questions answered
Do you cover smaller places like Edgehead?
Yes, Edgehead is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How do Scotland’s building regulations apply to fire-rated sealant in Edgehead?
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’s how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
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 much does fire rated sealant cost in Edgehead?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
How the job changes by surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
What we seal
- Linear gaps
- Service penetrations

Commercial buildings in Edgehead
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details, though we do not certify buildings or do fire risk assessments.
If you let a flat or house near Newtongrange station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Cranston Parish Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
