About our fire rated sealant in Crossmichael
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have seals cut through by electricians, plumbers or data installers and unsealed gaps around fire door frames, we can help.
If you look after holiday lets, a guest house or a community building in or near Crossmichael, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep the record of products and locations with your fire safety documents
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
- Include fire stopping when you schedule refits
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.
Surface by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the sealant bonds.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
What fire rated sealant looks like in Crossmichael
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 don’t certify buildings or do fire risk assessments.

Do you need fire rated sealant in Crossmichael?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.
People normally contact us when they notice something like this:
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls
- Door frames with gaps between frame and wall
- Standard silicone or caulk in a fire-stopping gap
If you look after a church, hall or community building such as Balmaghie Parish Church And Churchyard, older buildings that have had new heating or wiring often have service gaps worth checking.

Why it’s worth doing now in Crossmichael
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own. In an older home around Crossmichael, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- 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
- Let us know about parking restrictions
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

Common questions in Crossmichael
Will you come out to Crossmichael?
Yes, smaller places are covered as well as towns. We work across all of Scotland. 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 Crossmichael?
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.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, large or small.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
