Fire rated sealant for homes and businesses in Langholm
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, one gap at a time. If you are dealing with open gaps behind door architraves and fire seals that have cracked with movement, we can put it right, on door frames, plasterboard & masonry and flats & HMOs alike.
For a place like Langholm, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.
Each job carries a 12-month guarantee.

What we are called out for in Langholm
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Most people get in touch when they notice one of these:
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
For buildings such as Erskine Church, service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- What the cure time is
- How the joint is cleaned and prepared
- What happens if the job turns out different
- The length of the guarantee
When something else is needed
Before booking, it’s worth knowing the limits:
- Assessing a building’s fire safety
- Sign-off of the building, which sits with building control or your assessor
- A wall that is not a fire-resisting element to begin with
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Outdoor work around Langholm depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Getting ready for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Advice
What the job involves on each surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail and we flag any that need another system.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.
Commercial buildings in Langholm
Langholm has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details; we do not certify buildings or carry out fire risk assessments.
For site and facilities teams at buildings such as Langholm Academy, service openings in fire-resisting walls need checking after any refurbishment.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What affects the cost of fire rated sealant
You will get a clear quote before we start. It’s based on:
- Which sealant suits the joint
- The number and length of the joints
- Access and height
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Questions from Langholm
How do Scotland’s building regulations apply to fire-rated sealant in Langholm?
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 is how we fit it. We do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Do you cover smaller places like Langholm?
Yes. Langholm is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep photos of seals that will be hidden
- Store the list of sealed gaps with your building paperwork
- Report cracked or damaged seals as soon as you notice them
- Keep general-purpose foam and caulk away from fire-stopping gaps
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.
